Published in Nature, the research showed that a healthy, balanced diet was linked to superior brain health, cognitive function and mental well-being. The study, involving researchers at the University of Warwick, sheds light on how our food preferences not only influence physical health but also significantly impact brain health.

The dietary choices of a large sample of 181,990 participants from the UK Biobank were analysed against and a range of physical evaluations, including cognitive function, blood metabolic biomarkers, brain imaging, and genetics unveiling new insights into the relationship between nutrition and overall well-being.

The food preferences of each participant were collected via an online questionnaire, which the team catagorised into 10 groups (such as alcohol, fruits and meats). A type of AI called machine learning helped the researchers analyse the large dataset.

A balanced diet was associated with better mental health, superior cognitive functions and even higher amounts of grey matter in the brain linked to intelligence compared with those with a less varied diet.

The study also highlighted the need for gradual dietary modifications, particularly for individuals accustomed to highly palatable but nutritionally deficient foods. By slowly reducing sugar and fat intake over time, individuals may find themselves naturally gravitating towards healthier food choices.

Genetic factors may also contribute to the association between diet and brain health, the scientists believe, showing how a combination of genetic predispositions and lifestyle choices shape well-being.

Lead Author Professor Jianfeng Feng, University of Warwick, emphasised the importance of establishing healthy food preferences early in life. He said: "Developing a healthy balanced diet from an early age is crucial for healthy growth. To foster the development of a healthy balanced diet, both families and schools should offer a diverse range of nutritious meals and cultivate an environment that supports their physical and mental health."

Addressing the broader implications of the research, Prof Feng emphasized the role of public policy in promoting accessible and affordable healthy eating options. "Since dietary choices can be influenced by socioeconomic status, it's crucial to ensure that this does not hinder individuals from adopting a healthy balanced dietary profile," he stated. "Implementing affordable nutritious food policies is essential for governments to empower the general public to make informed and healthier dietary choices, thereby promoting overall public health."

Co-Auhtor Wei Cheng, Fudan University, added: Our findings underscore the associations between dietary patterns and brain health, urging for concerted efforts in promoting nutritional awareness and fostering healthier eating habits across diverse populations.

Dr. Richard Pemberton, Certified Lifestyle Physician and GP, Hexagon Health, who was not involved in the stud, commented: This exciting research further demonstrates that a poor diet detrimentally impacts not only our physical health but also our mental and brain health. This study supports the need for urgent government action to optimise health in our children, protecting future generations. We also hope this provides further evidence to motivate us all to make better lifestyle choices, to improve our health and reduce the risk of developing chronic disease.

New research shows profound link between dietary choices and brain health - Anti Aging News

Kelly Clarksons image has been repeatedly misappropriated online to purportedly sell diet products.

Weve debunked multiple claims including several involving altered videos that appear to show the singer endorsing diet products, but the original footage proves this didnt happen.

The latest scam weve encountered: a Facebook post warning users about "other Keto scam ads."

"Read the REAL stories of popular celebrities like Kelly Clarkson," the April 18 post says, "who have changed their lives beyond recognition with the help of our only officially licensed Keto product."

The post features a link with an image of Clarkson and text over her that reads: "I will clarify a fact regarding a scam "

The link leads to what looks like Kelly Clarksons Facebook page but isnt.

This post was flagged as part of Metas efforts to combat false news and misinformation on its News Feed. (Read more about our partnership with Meta, which owns Facebook and Instagram.)

The url at the link is a nonsensical series of letters, and Clarksons supposed post is a missive replete with typographical and grammatical errors about a weight loss journey that involved "the director of the Olympic opening ceremony" asking Clarkson to "lose 100 pound" for "the sake of national image."

We found no such post on Clarksons actual Facebook page. Weve also found no credible evidence that Clarkson has promoted weight loss gummies or other diet products.

Melissa Kates, Clarksons publicist, didnt respond to PolitiFacts questions about the post. But she has told The Associated Press that Clarkson "does not have any affiliation as a spokesperson" for any "weight loss products/programs."

We rate claims that Clarkson has promoted weight loss gummies or other diet products False.

GOTHENBURG, Sweden Irritable bowel syndrome is often misunderstood because of its many nuances and complexities. The chronic condition usually causes abdominal cramping, bloating, constipation, and diarrhea. Typically, either diet, medication, or both are used in the treatment. However, new research now shows that dietary treatment is actually more effective than medications when it comes to IBS.

Standard dietary advice for those with IBS includes things like focusing on eating smaller, more frequent meals rather than eating three larger ones. Additionally, greatly limiting common triggers like alcohol and coffee is widely advised. If medications are used, its typically to improve certain symptoms like constipation or bloating. Sometimes, even antidepressants are utilized.

To explore things further, a team of researchers conducted a study including adult patients with severe or moderate IBS symptoms at Sahlgrenska University Hospital in Gothenburg, Sweden. They compared three treatments: two dietary and one based on medication. The first group received conventional IBS dietary advice, like changing certain eating behaviors in combination with eating lower amounts of fermentable carbs commonly referred to as FODMAPs. High FODMAP foods are dairy and beans that can cause more pain and gas in people with IBS.

The second group was advised to eat a lower-carb, higher protein and fat diet. Then, the third group took medication based on the patients most pressing symptoms. Each group had around 100 participants, and the treatment period lasted four weeks. The researchers used an established IBS symptom scoring scale for analysis and found that, among those who received traditional IBS dietary advice and ate low-FODMAP foods, 76 percent had significantly reduced symptoms.

In the second dietary group, 71 percent had significantly reduced symptoms, while only 58 percent did in the medication group. Of note, all groups reported significantly better quality of life and reduced physical and mental symptoms.

At a six-month follow-up, when participants in the dietary groups had partially returned to their typical eating habits, 68 percent still had clinically significant symptom relief in the low FODMAP group, while 60 percent did in the low-carbohydrate diet group.

With this study, we can show that diet plays a central role in the treatment of IBS, but that there are several alternative treatments that are effective, says Sanna Nybacka, a researcher, dietitian, and study leader, in a media release.

We need more knowledge about how to best personalize the treatment of IBS in the future and we will further investigate whether there are certain factors that can predict whether individuals will respond better to different treatment options.

IBS treatment often needs to take many different approaches because of how variable it can present itself. There also isnt one cause of IBS, which inherently makes effective treatment measures more difficult to pinpoint.

Stress is often considered a big trigger, but a bacterial infection could also be behind someones gut trouble. Eating low FODMAP has been a top dietary intervention and definitely helps people find symptom relief as long as they stick to the dietary protocol.

This study showed that a majority of participants who partially returned to their previous eating habits after six months still reported relief. It would be interesting to see how those results hold true after one year or more.

For many with IBS, conventional dietary advice works for the short term, specifically while the guidance is being followed. Typically, once people allow more leniency in their diet, they find themselves back at square one at some point. For these reasons, taking a deeply individualized approach to care for IBS patients is important for providing lasting results. If you think you may be struggling with IBS, be sure to work with an experienced physician and registered dietitian who specializes in gastrointestinal health.

The findings are published in The Lancet Gastroenterology & Hepatology.

What do weight loss drugs mean for a diet industry built on eating less and exercising more? - WV News

Jane Ammeson Times correspondent

Dr. Shishin Yamada, colorectal surgeon at of Silver Cross Hospital, notes the symptoms that should prompt a checkup for colon cancer.

Four years ago, the death of 43-year-old actor Chadwick Boseman who starred in Black Panther among other movies,was stunning. It also brought tolight that colorectal cancer wasnt just a disease for those 55 and older.

The American Cancer Society reports that the number of people younger than 55 diagnosed with colorectal cancer (which includes cancers of the colon and rectum) doubled to 20% (1 in 5) in 2019 from 11% (1 in 10) in 1995.

Colon cancer is on the rise, including a surge in people in their 20s, 30s and 40s, and it is predicted that around 20,000 diagnoses, and nearly 4,000 deaths from advanced colon cancer occur in people younger than 50, says Dr. Shishin Yamada, a board-certified general surgeon at Silver Cross Hospital in New Lenox. According to the American College of Surgeons, colon cancer has moved up to the No. 1 cause of cancer death in men and No. 2 in women (after breast cancer in women younger than 50), where just 20 years ago colon cancer was No. 4 4 cause in the 1990s.

The reasons for this uptick aren't clear but some of the same causes of colon cancer in older adults are likely at work.

Diets high in red meats, processed foods, fats and fried foods as well as those low in fiber are considered risk factors, says Bethany Wignall, an oncology nurse navigator at the Methodist Hospitals Oncology Institute.

Heavy alcohol use and smoking and lack of fruits and vegetables in a diet also may increase risk, she continues.

Other risk factors include adenomatous or pre-cancerous polyps, a history of colorectal cancer and/or inherited conditions.

Lynch syndrome is the most common hereditary condition, says Wignall. Its linked to 2-4% of all colorectal cancers. The lifetime risk of colorectal cancer in people with Lynch syndrome is between 10-80%.

Environmental factors may come into play as well. The National Toxicology Program, part of the National Institutes of Health,has identified 18 chemicals that cause cancer in the intestines of mice or rats. These chemicals might damage DNA and thus lead to harmful mutations in colon and rectal cells.

A new study by researchers at the Fred Hutchison Cancer Center in Seattle have discovered a link between a microbe found in the mouth and a more aggressive colon cancer. In 200 people studied, the microbe was present in 50% of the patients. Testing for the microbe can result in earlier screening and improved treatments, the researchers note.

One thing is clear, it is not just genetics. There are many more cases out-of-the-blue occurring sporadically in those under 50, says Shishin.

Screening and lifestyle changes are the best way to prevent colorectal cancer or catch it early, when it is much more likely to be successfully treated.

Shishin says that young people, like everyone else, need to communicate and see a doctor for such symptoms as rectal bleeding, blood in their stools and/or blood in the toilet after a bowel movement.

Other signs to look for include unusual looking stools.

Digested blood, if it's had time to go through your bowel, may have the iron stripped out, and then it looks more like iron ore, dark or black stools, he says. Sometimes a tumor may compress the stool passing by, like a pasta-maker, so talk to your doctors if you notice narrow, thin or ribbon pasta like stools.

Diarrhea and constipation (fewer than three bowel movements per week) can indicate a problem particularly if these conditions last more than two weeks. Low energy and/or feelings of being more tired than usual can indicate a slow and chronic blood loss that may also be a symptom of colorectal cancer.

Even if you are a young woman with chronic anemia that you assume is due to menstrual bleedings, it's not a bad idea to check for other causes, says Shishin. Obstruction and pain are late symptoms, so many early colon cancers may not feel much wrong if at all. Your most reliable symptom checker is yourself and to communicate these symptoms with your doctor.

As a result of this significant increase in colon cancer, 45 is the new 50 to begin colorectal cancer screening, says Wignall, noting that the U.S. Preventive Services Task Force updated its colorectal screening recommendation in 2021. Screening earlier may moderately increase life-years gained and decrease colorectal cancer cases and deaths compared with beginning screening at age 50, she says.

Shishin notes that the colonoscopy is what's considered a gold standard test, a test that works great and has withstood the test of time.

It's been the gold standard for 50 years now, he says of the outpatient procedure that involves a small flexible fiberoptic camera on a tube inserted in the rectum while the patient is under light anesthesia. We look at the walls of the colon for abnormalities and can take samples and remove lesions.

If cancer is discovered, treatment depends upon its stage and can include surgery, chemotherapy, radiation therapy and immunotherapy.

Paying attention to any symptoms, communicating with your doctor and knowing that colorectal cancer is surging are all necessary steps that, according to Shishin, just might save your life.

Not-So-Sweet Deal

A campaign without reporting is like an undressed salad. But Sweetgreen has to eat it anyway.

Ive been pushing my Google reps, the brands director of media and growth Jeff Lin declared during a panel at the Possible conference in Miami, Adweek reports. You want me to spend more money, give me more reporting.

Lin also urged advertisers not to inherently trust an ad platforms own measurement reports, which have a tendency to, you know, over-attribute the value of their own media.

One issue many advertisers have with PMax, for example, is that it doesnt distinguish between Google channels, which makes it hard to know exactly whats working. PMax reports everything as Google.

Sweetgreen must also untangle local campaigns. PMax may power up campaigns in certain cities, for instance, if thats where conversions happen. But Sweetgreen wants more local visibility and control.

Too bad.

Brands may take a tough tone with Google, but almost all accept the visibility trade-off.

Do you care whether its display or video, or did you just care about getting the conversions and the revenue? Lin says.

Thats kind of a rhetorical question.

Mired In MFA

Ad verification vendors arent the only ones in the hot seat over made-for-advertising (MFA) sites.

Advertisers and agencies are also scrutinizing the Media Rating Council (MRC), which accredits the verification vendors responsible for blocking MFA from the programmatic bid stream.

The definition of MFA has shades of gray, but the recent case of a Forbes MFA subdomain exemplifies probably the highest level of fraud, a marketing exec tells Ad Age. It certainly counts as domain spoofing, which MRC standards are meant to address and yet.

The MRC says its been working to update its invalid traffic standards since 2022 but buyers cant wait years.

With MFA in the spotlight, the MRC is now hurrying to update its standards by the end of the month.

The new standards will direct verification vendors to compare the header-bidding wrapper of a bid request with log-file data. The MRC will also put more pressure on vendors to identify and prevent instances like the Forbes www3 subdomain.

Even so, MRC CEO George Ivie told AdExchanger earlier this month that its unlikely vendors will lose accreditation unless the organization spots what it considers material noncompliance.

Whose Tube?

Nielsens monthly TV ratings report is out, and it underscores some interesting trends in the category.

Cable TV loses out overall surprising nobody. But live news and sports still drive real scale and perhaps account for why broadcast ad revenue is so persistent. In May 2021, when Nielsen first launched this report, which it called The Gauge, broadcast accounted for 25% of television viewership. Now its 22.5%. Not bad, considering.

Broadcast got a boost this year from high ratings for the State of the Union speech and NCAA basketball tournaments, especially the womens tourney.

Another insulator for the traditional broadcast business is that cable TV as a medium is down, but cable content viewership is up.

Some of that shift has come from FAST channel providers (Pluto TV, The Roku Channel and Tubi TV), with a considerable portion of the titles being fueled by cable network content, Nielsen writes.

Another standout is the YouTube app, which now represents 9.7% of all TV viewership.

Netflix, by comparison, gained 0.8% market share year over year which is outstanding, by the way. Hulu, Disney and Amazon lost share in that time. (YouTube gained 1.9% share.)

Sweetgreen Wants A Healthy PMax Diet; The MRCs MFA Quagmire - AdExchanger

The climate crisis is becoming a direct threat to all. Extreme weather phenomena are accelerating in frequency and intensity, provoking death and disease, social and economic turmoil. Greece, Cyprus and other parts of Southern Europe are on the front line. It is possible that in 10 years their environment will resemble that of the Middle East.

There is a pressing need to reduce emissions of greenhouse gases, as the Earths average temperature is heading towards being close to 3 degrees Celsius higher than pre-industrial levels at the end of the century, almost double the target set by international agreements. Fossil fuels account for 70 percent of these emissions, food production for the other 30 percent. If humanity were to adopt a healthier diet, if it applied sustainable methods of food production, this could be halved, to 15 percent.

Scientists who study the problem propose solutions. But developments demand faster procedures, more initiatives, so that this knowledge can be translated immediately into effective policies. This was the subject of a very interesting discussion organized by the Academy of Athens Center for Public Health Research and Education and Harvards T.H. Chan School of Public Health (HSPH) at this years Delphi Economic Forum.

We need to listen to each other and come up with solutions that benefit everyone, said Walter Willett, professor of epidemiology and nutrition at HSPH, one of the worlds leading scientists in the field. He noted that shifting to a model such as the Mediterranean diet would have health benefits, would reduce greenhouse gas emissions and would lead to economic savings.

Antonia Trichopoulou, member of the Academy of Athens and a pioneer of research into the Mediterranean diet, stressed that this is not simply a diet but also social practice based on skills, knowledge and tradition. It is a model for sustainable nutrition with a low burden for the environment.

Klea Katsouyanni, professor of public health at Londons Imperial College, focused on the impact of climate change, food systems and other environmental exposures on health. She highlighted the threat posed by air pollution and non-optimal temperature, especially when they combine, adding that social inequality amplifies this. Petros Koutrakis, professor of environmental science at the HSPH, presented the problems faced by Greece and the need for new models of production. He called for a national strategy that is not dependent of the European Union, as countries do not all face the same challenges. He noted the need to safeguard the health of people and to protect the environment from the consequences of the climate crisis.

In a video presentation, Kari C. Nadeau, John Rock Professor of Climate and Population Studies at the HSPH, presented the three key pillars of food system transformation, Consumption: shifting diets towards healthy plant-based diets consistent with Mediterranean diet principles. Production, processing, distribution: improving agricultural production methods. Reducing food waste and loss.

Lluis Serra Majem, rector of the University of Las Palmas, sent a message presenting an initiative for spreading the need for a sustainable diet, like the Mediterranean one, in Latin America and Africa. The mission will be undertaken by a task force of six distinguished women to whom his university has awarded honorary doctorates.

The aim of Wednesdays session (and of a discussion the previous day which included officials from the ministries of Economy and Rural Development) was to find a way for the scientists knowledge to contribute towards shaping policy for managing the climate crisis fallout, for the sustainable cultivation of products based on better nutrition models. Working groups will be established for this. Rural Development Minister Lefteris Avgenakis, who took part in Wednesdays discussion, welcomed the initiative and explained his ministrys priorities and policy.

This discussion may not have been on Delphis center stage. But it is a substantial step towards the necessary cooperation between science and politics, between various ministries. It also provided the crucial knowledge that this existential crisis demands.

A healthy diet for people and the environment - Kathimerini English Edition

Sumamry: A high-fat, sugary diet during adolescence may cause long-lasting memory impairments. The study found that rats raised on a junk food diet exhibited significant memory deficits that persisted into adulthood, despite switching to a healthier diet.

These effects were linked to disruptions in acetylcholine, a crucial neurotransmitter for memory and learning, highlighting the critical impact of diet on brain development. The research suggests that poor dietary habits in youth could have irreversible effects on cognitive functions.

Key Facts:

Source: USC

A new USC-led study on rats that feasted on a high-fat, sugary diet raises the possibility that a junk food-filled diet in teens may disrupt their brains memory ability for a long time.

What we see not just in this paper, but in some of our other recent work, is that if these rats grew up on this junk food diet, then they have thesememory impairmentsthat dont go away, said Scott Kanoski, a professor of biological sciences at the USC Dornsife College of Letters, Arts and Sciences.

If you just simply put them on ahealthy diet, these effects unfortunately last well into adulthood.

Thestudyappears in the May issue of the journalBrain, Behavior, and Immunity.

In developing the study, Kanoski and lead author and postdoctoral research fellow Anna Hayes considered thatprior researchhas shown a link between poor diet and Alzheimers disease.

People who suffer from Alzheimers disease tend to have lower levels of a neurotransmitter called acetylcholine in the brain that is essential for memory and functions such as learning, attention, arousal and involuntary muscle movement.

The team wondered what this could mean for younger people who may be on a similar fat-filled, sugary Western diet, particularly during adolescence when their brain is undergoing significant development.

By tracking the impact of the diet on the rats levels of acetylcholine, and running the rats through some memory testing, they could learn more about the important relationship between diet and memory.

The researchers tracked the acetylcholine levels of a group of rats on a fatty, sugary diet and in a control group of rats by analyzing their brain responses to certain tasks designed to test their memory. The team examined the rats brains post-mortem for signs of disrupted acetylcholine levels.

The memory test involved letting the rats explore new objects in different locations. Days later, the researchers reintroduced the rats to the scene that was nearly identical except for the addition of one new object.

Rats on the junk food diet showed signs they could not remember which object they had previously seen, and where, while those in the control group showed familiarity.

Acetylcholine signaling is a mechanism to help them encode and remember those events, analogous to episodic memory in humans that allows us to remember events from our past, lead author Hayes explained.

That signal appears to not be happening in the animals that grew up eating the fatty, sugary diet.

Kanoski emphasized that adolescence is a very sensitive period for the brain when important changes are occurring in development.

I dont know how to say this without sounding like Cassandra and doom and gloom, he said, but unfortunately, some things that may be more easily reversible during adulthood are less reversible when they are occurring during childhood.

There is at least some hope for intervention. Kanoski said that in another round of the study, the research team examined whether the memory damage in rats raised on the junk food diet could be reversed with medication that induces the release of acetylcholine.

They used two drugs, PNU-282987 and carbachol, and found that with those treatments given directly to the hippocampus, abrainregion that controls memory and is disrupted in Alzheimers disease, therats memory ability was restored.

But without that special medical intervention, Kanoski said more research is needed to know how memory problems from a junk food diet during adolescence can be reversed.

In addition to Kanoski and Hayes, the team included other USC Dornsife researchers Logan Tierno Lauer, Alicia E. Kao, Molly E. Klug, Linda Tsan, Jessica J. Rea, Keshav S. Subramanian, Cindy Gu, Arun Ahuja, Kristen N. Donohue and La Dcarie-Spain; Natalie Tanios of Keck School of Medicine of USC; as well as Anthony A. Fodor, Shan Sun of University of North Carolina-Charlotte.

Original Research: Open access. Western diet consumption impairs memory function via dysregulated hippocampus acetylcholine signaling by Anna M.R. Hayes et al. Brain, Behavior, and Immunity

Abstract

Western diet consumption impairs memory function via dysregulated hippocampus acetylcholine signaling

Western diet (WD) consumption during early life developmental periods is associated with impaired memory function, particularly for hippocampus (HPC)-dependent processes.

We developed an early life WD rodent model associated with long-lasting HPC dysfunction to investigate the neurobiological mechanisms mediating these effects. Rats received either a cafeteria-style WD (ad libitumaccess to various high-fat/high-sugar foods; CAF) or standard healthy chow (CTL) during the juvenile and adolescent stages (postnatal days 2656).

Behavioral and metabolic assessments were performed both before and after a healthy diet intervention period beginning at early adulthood.

Results revealed HPC-dependent contextual episodic memory impairments in CAF rats that persisted despite the healthy diet intervention. Given that dysregulated HPC acetylcholine (ACh) signaling is associated with memory impairments in humans and animal models, we examined protein markers of ACh tone in the dorsal HPC (HPCd) in CAF and CTL rats.

Results revealed significantly lower protein levels of vesicular ACh transporter in the HPCd of CAF vs. CTL rats, indicating chronically reduced ACh tone. Using intensity-based ACh sensing fluorescent reporter (iAChSnFr)in vivofiber photometry targeting the HPCd, we next revealed that ACh release during object-contextual novelty recognition was highly predictive of memory performance and was disrupted in CAF vs. CTL rats.

Neuropharmacological results showed that alpha 7 nicotinic ACh receptor agonist infusion in the HPCd during training rescued memory deficits in CAF rats.

Overall, these findings reveal a functional connection linking early life WD intake with long-lasting dysregulation of HPC ACh signaling, thereby identifying an underlying mechanism for WD-associated memory impairments.

Junk Food Diet in Teens Linked to Long-term Memory Issues - Neuroscience News

Dear Dietitian,

I just read an article that said a high-fiber diet helps prevent colon cancer, but other articles on this topic have said the opposite. Can you help clear things up?

Joseph

Dear Joseph,

Scientific studies are often confusing because the results are different. Before something becomes clear in science, it has to be tested several times in different cultures in various parts of the world. It must also be tested on men and women of different ages. The -studies must reveal the same results to be accepted as valid by the scientific community. Sometimes this takes several years.

Nutrition studies seem even more confusing because nutrition is in its infancy. We have barely scratched the surface of most nutrition topics. When a new topic is studied, results often vary until the matter is hammered out. The good news is that we are learning more about nutrition now than at any other time in history.

A study of the role of fiber in disease prevention was published in The Lancet in February 2019. Researchers found a 16-24% decrease in rates of heart disease, strokes, type 2 diabetes, and colorectal cancer when comparing people with the highest dietary fiber consumption with those who ate the least amount. Furthermore, there was a 15-30% reduction in death from any cause in the high-fiber group. It is important to note the study was conducted on fiber in food, not supplements.(1) As with most nutrition studies, this was an observational study, which does not show cause and effect. Even so, it strongly suggests that fiber is a crucial ingredient of a healthy diet.

Researchers assigned high fiber intake as 25 to 29 grams daily. Americans eat about half that amount. When increasing fiber, do so gradually, and drink plenty of water; otherwise, you may feel uncomfortable, and the gas your body produces may make you unpopular.

Good sources of fiber include fruits, vegetables, nuts, seeds, and whole grains. As always, choose foods you enjoy. Start with highfiber cereal, one with 5 grams of fiber or more per serving. Add three fruits each day to increase fiber by another 12 grams. Youre already up to 17 grams. Next, have two slices of whole wheat bread on your sandwich at lunch (2 grams of fiber). Include one-half cup of beans (7 grams). Finally, enjoy one-half cup of green peas (4 grams) at dinner, and you have 30 grams of fiber for the day. Bon apptit.

Until next time, be healthy.

From shakes to meal prep, it seems like everyones trying to get more protein in their diet. But which protein sources are best?

We asked an expert for seven ways to add more protein into your diet.

Protein needs vary from person to person, says Cassandra Vigue, RDN, registered dietitian with Hartford HealthCare, but she says theres a good rule of thumb you can follow.

Anywhere from 20-25% of your daily calories should come from protein, says Vigue.

Not sure how to eyeball it?

You should be aiming for 3-4 ounces of protein per meal, which is roughly the size of your palm, she says. And its important to incorporate protein in your snacks, too, to stay full throughout the day.

It probably doesnt come as a surprise, but lean meat tops the list.

Lean, or low-fat, protein is typically the best option, says Vigue. If its possible, choose something without skin or visible fat. These include chicken breast, pork tenderloin and 90% lean ground beef.

They arent just great sources of protein, these foods are also packed with zinc and iron.

Zinc supports the immune system and helps your metabolism, while iron is key for red blood cell production, Vigue notes.

Low in bad fat and high in good fat, fish is another promising option.

Fish tends to be lower in both fat and calories than other animal proteins, making it a popular choice. Its also rich in omega-3 fatty acids, which are important for heart health, says Vigue.

Not sure where to start? Here are some of the most nutrient-dense fish you can choose:

These arent just a healthy carbohydrate, theyre a great source of protein, too.

Legumes offer plenty of different benefits, says Vigue. Theyre known for their fiber and protein, but are also loaded with folate, potassium, iron and zinc. Theyre also versatile you can substitute them for a carbohydrate or a protein to get some extra nutrients.

New to eating legumes? Here are a few to try:

These are easy to add to salads, grain bowls or even stews for some extra protein or fiber. Or you can use chickpeas for a homemade hummus spread, which is great to add to wraps, says Vigue.

Sound too intimidating? Try starting with a simple substitution like lentil pasta.

Struggling to get enough protein in your diet without relying on meat? Look no further.

Soy proteins like tofu and tempeh are some of the most nutritious options out there. These are considered complete proteins, because they contain all nine essential amino acids that our body needs to promote healthy cell growth, says Vigue.

And if one bad experience with tofu put you off?

Just like meat, soy proteins should be well seasoned, says Vigue. I love to break tofu up and saut it in a pan like ground beef, or marinate it and bake or air fry until crispy.

Looking for another plant-based option? Nuts make a great snack, while seeds can be roasted with olive oil for a savory treat.

Like everything, its important to have these in moderation, says Vigue. Nuts can be high in calories, so try to stick to a portion size of one ounce (or roughly a quarter cup).

Both nuts and seeds have a variety of different benefits, ranging from fiber to healthy fats. Choose options like:

If buying lean meat for every meal just doesnt seem practical anymore, eggs offer an inexpensive alternative.

Eggs are packed with amino acids the building blocks for protein, Vigue notes.

And according to some research, eating an egg every day can also reduce your risk of a stroke.

The best way to get protein is from whole foods, says Vigue.

Solid protein, from the food you eat, will make you feel more full because it takes longer to chew and digest, she says.

But protein shakes can still have a role in your diet.

If you need a quick source of protein as a snack, these shakes can be a good option. Theyre also a better choice than skipping a meal altogether, she adds.
