When it comes to ideas about healthy eating, there are all sorts of rules, trends and advice about what’s good for you and what isn’t.

Some of the guidance may be legitimate — yet some of it should be taken with a grain of salt.

Multiple experts and researchers from Mass General Brigham in Boston investigated some popular diet concepts that have been circulating — and separated fact from fiction.

Here are six popular concepts — and a clear explanation of whether they hold water or not, according to experts.

True or false?

1. ‘To live longer, women should follow the Mediterranean diet’

True. In recent studies, the Mediterranean diet has been shown to be beneficial for overall health.

Mass General supports this theory, referencing its own study that found women who followed the nutrition plan for more than 25 years had up to 23% lower risk of mortality, with reductions in cardiovascular and cancer-related deaths.

The study also found that introducing a single component of the diet led to a 5% reduction in the long-term risk of death from certain diseases.

The Mediterranean diet incorporates healthy foods like fruits, vegetables, legumes, olive oil, nuts and fish, while avoiding sugar and processed or red meats.

Most people don’t realize the impact diet has on health and longevity, according to Samia Mora, M.D., director of the Center for Lipid Metabolomics at Brigham and Women’s Hospital.

“What we eat today has major implications for living a long and healthy life,” she wrote in a statement to Fox News Digital.

“The benefits [of the Mediterranean diet] were seen for both cancer and cardiovascular mortality – the top two causes of death for women and men – and related to multiple biological mechanisms, in particular to lower inflammation and insulin resistance and improved metabolism.” 

2. ‘Removing trigger foods is always the best treatment for digestive issues’

False. While some people do suffer from food allergies or autoimmune conditions, the experts at Mass General found this diet concept to be false overall — as many digestive symptoms are known to have “more complex causes.”

When patients have bad reactions to certain foods, it’s not the food itself causing the issues, but the digestive tract’s response to eating “in general,” according to Kyle Staller, M.D., director of the Gastrointestinal Motility Laboratory at Massachusetts General Hospital.

A poor digestive response might not just be caused by the food you’re eating, a doctor said. (iStock)

“While some people have true allergies to certain foods (for example, an allergy to gluten in celiac disease) or an inability to digest certain foods (such as dairy in lactose intolerance), many symptoms attributed to specific foods are actually driven by your body’s response to eating,” he told Fox News Digital. 

Eating starts a “cascade of nerve activity in the gut” regardless of the kind of food that’s eaten, according to Staller.

Those with sensitive gut nerves can develop GI discomfort in the form of gas, bloating and a feeling of abnormal fullness.

“These are what we call ‘disorders of gut-brain interaction’ — feeling abnormal sensations even when digestion is seemingly working normally,” Staller said. 

Eating starts a “cascade of nerve activity in your gut” regardless of the kind of food that’s eaten, a doctor said. (iStock)

“Irritable bowel syndrome (IBS) is the most classic example.” 

The best way to alleviate these symptoms is to target the abnormal nervous system responses while only eliminating the “most troublesome” foods, according to Staller.

3. ‘Eating blueberries can decrease the risk of some eye diseases’

True. The researchers found this claim to be true: Blueberries indeed can be beneficial for your eyes.

IS A SALAD ALWAYS A BETTER CHOICE THAN A SANDWICH? THINK TWICE ABOUT THAT

A Mass General study of nearly 40,000 U.S. middle-aged and older women found that one or more servings of blueberries per week was associated with a 28% lower risk of age-related macular degeneration (AMD), an eye condition that can lead to significant vision loss.

Dr. Howard D. Sesso, director of nutrition and supplements research at Brigham and Women’s Hospital, confirmed that blueberries can optimize eye health.

“Blueberries contain anthocyanins, a bioactive polyphenol that gives them their blue color, and has been linked with possible reductions in eye disease,” he told Fox News Digital.

4. ‘Following a plant-based diet will always improve health outcomes’

False, with caveats. Mass General experts say a plant-based diet is not always the best way to go, though it may seem super healthy.

Plant-based nutrition plans have “diverse and sometimes contrasting health effects,” according to Dr. Qi Sun, associate professor of medicine at Brigham and Women’s Hospital.

“Diet is not a magic bullet by itself.”

A plant-based diet that is dense in refined grains, sugary beverages and candies differs greatly from one containing fresh fruits and vegetables, whole grains, coffee, tea and more, he noted.

Plant-based diets should be well-rounded to include fruits, vegetables and whole grains, according to an expert. (iStock)

The first diet is associated with “many adverse health outcomes,” according to the researchers.

The second diet is considered a “healthy version of a plant-based diet,” which Sun said has been “robustly associated with better health outcomes, including lower risk of developing diseases such as diabetes, obesity and gout.”

The “healthy version” of a plant-based diet is proven to lower the risk of developing diseases such as diabetes, obesity and gout, experts say. (iStock)

In a statement sent to Fox News Digital, Sun encouraged people to focus on quality ingredients — such as fresh fruits, non-starchy vegetables, whole grains, legumes and nuts, and olive oil and other vegetable oils — and to limit sugary and salty foods.

“Don’t forget regular activity and other healthy lifestyle choices,” he advised. “After all, diet is not a magic bullet by itself.”

5. ‘Food location in the grocery store has no impact on purchases’

False. Mass General deemed this concept as flat-out “false,” as the “choice architecture” of the grocery store “strongly influences what we purchase.”

When healthy items are stocked in visible or convenient locations, that increases the likelihood of making a healthier choice, according to the researchers.

“Healthy choice architecture” refers to when healthy items are stocked in visible or convenient locations, Mass General reported. (iStock)

In the Mass General Hospital cafeteria, the foods and beverages are labeled as red, yellow and green – red being the least healthy and green being the most healthy.

The researchers found that when the healthiest items were in convenient locations or at eye level, employees were more likely to make healthier choices.

Anne Thorndike, M.D., primary care physician at Massachusetts General Hospital, shared with Fox News Digital that the opposite is also true.

People are more likely to choose food items that are convenient and visible, researchers said. (iStock)

“This is well-known by the food industry, which has been placing sugar-sweetened beverages, salty snacks, candy and baked goods in checkout lanes, aisle endcaps and at the front of store,” she said. 

6. ‘Early introduction of foods like peanut butter can prevent allergies’

True. Introducing a small child to foods known to cause allergic reactions can be scary for parents, but Mass General confirmed it can be beneficial in the long run.

Introducing “developmentally appropriate” forms of peanuts to children between 4 and 6 months old can cause an 80% reduction of peanut allergy in those who are at high risk, according to the LEAP Trial (Learning Early About Peanut Allergy).

Michael Pistiner, M.D., director of Food Allergy Advocacy, Education and Prevention at Mass General Hospital for Children, stressed that these findings show that “timing is important.”

“Once a child reaches a pediatric allergist, it might be too late to prevent some food allergies that could have been avoided with early allergen introduction and family education,” he told Fox News Digital.

Pistiner added, “With limited access to allergy providers and long wait times that can exceed three months, primary care clinicians play a crucial role in supporting families through infant feeding, early allergen introduction, eczema management, and food allergy diagnosis and referral.”

Dementia may be a disease of the mind, but its effects can be highly emotional.

Those suffering from cognitive decline can experience frequent changes in emotions and have less control over their feelings, according to the Alzheimer’s Society — which can make communication difficult.

“Most people do not have regular interactions with those living with dementia, so it can be hard to know the do’s and don’ts of what to say and how to behave,” Dana Eble, outreach manager for the Alzheimer’s Caregivers Network in Detroit, Michigan, told Fox News Digital.

DEMENTIA HAS 2 SHOCKING NEW RISK FACTORS, STUDY FINDS, WITH TOTAL OF 14 NOW ON LIST

“Unfortunately, even the most well-meaning of interactions can lead to stress or confusion for someone experiencing cognitive decline.”

When communicating with a dementia patient, experts say it’s important to choose your language carefully and avoid certain phrases or questions, including the items on the list that follows.

1. ‘Don’t you remember?’

This topped the list as the worst question to ask someone with dementia, according to experts.

“This question can be frustrating or embarrassing for someone with dementia, as memory loss is a central symptom of their condition,” Timothy Frie, a nutritional neuroscientist in Atlanta, Georgia, who studies how traumatic stress causes neuroinflammation, told Fox News Digital.

HIGH BLOOD PRESSURE AND ALZHEIMER’S DISEASE COULD GO HAND IN HAND, STUDY FINDS

“It can make them feel inadequate or upset about their cognitive decline.”

Forcing the person to acknowledge that they don’t remember a memory or conversation can make them feel bad, added Christina Chartrand, the Florida-based vice president of Senior Helpers, a home care company that often helps dementia patients.

2. ‘Let me do that for you’

One of the hardest parts of having dementia is the daily realization of things that can no longer be done independently, according to Adria Thompson, a licensed speech-language pathologist in Massachusetts with 10 years of experience in dementia care.

It is best to avoid arguing or reasoning with someone with dementia, as it will likely anger and agitate them, experts said.  (iStock)

“Often, well-meaning individuals might prematurely take over tasks without asking or assessing if they need to, which can diminish the person’s sense of autonomy,” she told Fox News Digital. 

“Instead of assuming they can’t do something, it’s more respectful to offer help and let them tell you if they need it — and allow them to still do the things they can for as long as possible.”

3. ‘You’re wrong’

It is best to avoid arguing or reasoning with someone with dementia, as it will likely anger and agitate them, experts agreed.

HEALTH CARE IS ‘OVERWHELMINGLY COMPLEX’ FOR OLDER ADULTS, EXPERTS SAY: ‘EVER-INCREASING HURDLE’

“People with dementia do not need to be corrected when they believe it’s Tuesday the 13th and not Monday the 1st,” Elizabeth Landsverk, M.D., a California-based geriatrician and founder of Dr Liz Geriatrics, an online education and support resource, told Fox News Digital.

“Keep the peace,” she advised. “It’s better than being right.”

4. ‘Would you like to make plans for next week?’

“As dementia patients lose their sense of time, they lose a frame of reference that would make this question meaningful to them,” said Leonie Rosenstiel, president of Dayspring Resources, Inc., in Albuquerque, New Mexico, which helps families of elders plan and cope with the problems of aging. 

“Repeatedly pointing out that someone is repeating themselves can lead to feelings of frustration and self-consciousness” for that person, an expert said. (iStock)

“If you expect to do something with them at a particular time in the future, they will not be able to keep track of this appointment.”

To prevent frustration, Rosenstiel recommended ensuring that someone else can remember or write down the plans, and that those plans don’t conflict with activities such as medical appointments.

5. ‘You seem fine’

“Society often has a preconceived notion of what dementia looks and acts like, and if someone doesn’t fit that stereotype, it might seem tempting to use this phrase as a compliment,” noted Thompson.

“However, this phrase can belittle the individual’s daily struggle and experiences.”

It’s important to be aware that symptoms and experiences can vary greatly among individuals with dementia, Thompson told Fox News Digital.

6. ‘I just told you that’ or ‘You already told me that’

Along the same lines of “Don’t you remember?” experts recommend not asking questions or making statements that are likely to upset the person. 

Continually “pointing out that someone is repeating themselves can lead to feelings of frustration and self-consciousness,” said Frie.

“It’s better to gently redirect the conversation or respond as if it’s new information.”

This is especially true in the middle stages of their disease, when patients may have moments when they know their brain isn’t working right, according to Jennifer Fink, a caregiver expert in California who facilitates support groups for the Alzheimer’s Association.

7. ‘How have you been feeling this week?’

This might seem like a natural question to ask if it’s been a week since you’ve visited a loved one or friend, and you’re trying to catch up.

Yet it could do more harm than good, Rosenstiel said. 

“We ask each other questions like this all the time, but someone with dementia might not remember how they were feeling five minutes ago, let alone how they felt yesterday,” she warned. 

“They might make something up, in an effort to satisfy you, or they might get frustrated or angry.”

“Instead of assuming they can’t do something, it’s more respectful to offer help and let them tell you if they need it — and allow people to still do the things they can for as long as possible,” an expert advised. (iStock)

8. ‘You’re not making any sense’

Criticizing dementia patients’ communication can damage their self-esteem and discourage them from expressing themselves, according to Michael Kramer, a long-term care educator and director of community relations for retirement residences that accommodate seniors with dementia.

“Having patience and making an effort to understand their perspective helps to maintain their dignity and encourages open communication,” said Kramer, who is based in Ontario.

9. ‘Do you remember this?’

It’s best to avoid asking if the person recalls specific pieces of information, such a name or date or event, as it can put the person on the spot and feel like a test, experts said.

“Instead, start by introducing yourself,” Eble suggested — “something like, ‘Hey, Grandma, it’s Dana, your granddaughter!’ It might feel strange at first, but it will put your loved one at ease by reminding them of your name and connection to them.”

The same goes for events or memories, she said.

Instead of asking if they remember, start with “I remember when…” and then continue with your story. 

“Those with dementia love reminiscing, but don’t frame it as a test of their memory,” Eble added.

10. ‘You’re being difficult on purpose’

This phrase is “hurtful and dismissive,” Kramer warned. 

“It overlooks the fact that behavioral challenges are a result of the dementia itself, not intentional actions,” he said.

In some cases, phrasing activities as a question can cause confusion for a dementia patient, experts warned. (iStock)

“Using empathy and understanding instead of frustration is crucial in managing these situations.”

Labeling behavior as “difficult” can increase frustration and tension, Frie agreed.

“Understanding that challenging behaviors are often a symptom of the disease can help in responding with patience and empathy,” he said.

11. Using words like ‘bib’ or ‘diaper’

“As dementia progresses, caregivers may need to start using products to help with incontinence and/or to help make meal times easier,” Eble pointed out.

“Sometimes a limited choice is too much of an effort for a dementia patient.”

She recommended using positive language for these products, such as “protective underwear,” “cloth” or “apron.”

12. ‘Remember, she died last year, we went to the funeral…’

Reminding someone with dementia of the death of a loved one can be upsetting, as the person is likely not retaining this information, according to Kate Granigan, a geriatric social worker and president of the Aging Life Care Association Board in Boston.

“This can trigger a grief response over and over again, as if the information is newly learned,” she told Fox News Digital. 

Instead, she recommended saying something like, “It seems like you are really thinking about Uncle Harold today. Do you have a favorite memory from when you were kids?”

13. ‘That’s not how it happened’

“Dementia can cause confusion and altered perceptions of events,” said Kramer.

“Correcting someone sharply can increase their distress and confusion.”

Instead, it’s better to validate their experiences and gently guide them rather than insisting on correctness, the expert recommended.

14. ‘Do you want to [insert activity]?’

In some cases, phrasing activities as a question can cause confusion for a dementia patient, according to Eble.

“If you’re the primary caregiver in charge of your loved one’s toileting, showering, feeding or sleeping schedule, instead of asking ‘Do you want to,’ lead with ‘Let’s go to the [bathroom, shower, kitchen],’” she recommended. 

“Adding that bit of direction will help maintain their schedule.”

15. ‘What would you like to wear today?’

Open-ended choices may leave a dementia patient confused or frustrated, noted Rosenstiel. 

“They also might have no idea whether they’ll need a sweater or not, because they don’t remember what they heard on a weather report an hour ago,” she told Fox News Digital.

A more productive question might be, “Here’s a red sweater and a blue one. Which one would you rather wear?” 

“Even then, sometimes a limited choice is too much of an effort for a dementia patient,” the expert said.

16. ‘Get your coat and shoes, grab your bag and meet me by the door’

Long sentences with multiple parts or commands can be overwhelming and confusing for someone with dementia, according to Granigan.

“It is more successful to provide one short direction or piece of information at a time,” she told Fox News Digital. 

“Pause between each and guide the person through the task if needed before starting the next.”

The U.S. Food and Drug Administration (FDA) has approved a novel treatment that is designed to stop severe bleeding in a matter of seconds.

TRAUMAGEL — made by Cresilon Inc., a Brooklyn-based biotechnology company — is a plant-based hydrogel that comes in a pre-filled syringe, according to a press release. 

First responders, paramedics and combat medics can use the gel to rapidly stop severe blood loss from wounds due to gunshots, stabbings or other traumatic events.

BLOOD BANKS SEARCHING FOR TYPE O BLOOD AMID EMERGENCY SHORTAGE: ‘WE ALWAYS HAVE A NEED’

Joe Landolina, Cresilon’s CEO and co-founder, invented the gel in his dorm room when he was a 17-year-old chemical and bioengineering student at NYU.

There are currently many gauzes, powders and sponges used to stop bleeding, but they have limitations, according to Landolina. 

“Compared to TRAUMAGEL, these products are difficult to apply into wounds, as they must be packed physically into a bullet wound by a first responder, which is painful and highly risky,” he told Fox News Digital via email.

TRAUMAGEL, which is “the color and texture of hummus,” works by instantly creating a mechanical barrier against bleeding at the site of the wound, Landolina said.

“That barrier then allows the patient to quickly produce their own natural clot that doesn’t become incorporated with TRAUMAGEL, allowing TRAUMAGEL to then be removed without disturbing the clot.”

The gel is supposed to be removed within 24 hours.

Dr. Marc Siegel, senior medical analyst for Fox News and clinical professor of medicine at NYU Langone Medical Center, confirmed that this is the first gel-based hemostatic agent to be cleared for use in the U.S. to stop bleeding.

The product appears to be a “major step forward” in managing acute bleeding in the field — “even including head trauma and military uses [in combat], as well as gunshot and knifing wounds outside of combat,” Siegel told Fox News Digital.

“Also, it can be squirted from a syringe to get it into ‘nooks and crannies,’ and doesn’t require external pressure.”

Severe blood loss in traumatic wounds can kill in a matter of minutes, and is responsible for more than 35% of all pre-hospital deaths, studies show.

Up to 60% of hemorrhage deaths occur within the first three hours of injury.

The product is slated to launch in the U.S. in late 2024, according to the company.

Cresilon will target the U.S. military, trauma hospitals, emergency medical services (EMS) agencies and medical professionals who treat traumatic wounds, the company states.

When you walk into your favorite café for breakfast or to grab a morning coffee, you’ll likely spot a matcha option on the menu, too. 

Matcha has origins in China and became extremely popular in Japan.

More recently, it’s become a drink of choice in many other countries, including the United States. 

COFFEE VS. MATCHA TEA: WHAT DOES YOUR MORNING DRINK CHOICE SAY ABOUT YOU?

Matcha, which is green, offers consumers earthy notes in every sip. It’s a type of powered green tea made from the Camellia sinensis plant, which is similar to green tea. 

What really makes matcha different is the way the plant is grown, being protected by the shade leading up to its harvesting. When the plant is harvested, its stems and veins are removed, and the entire leaf is turned into a fine powder. 

Matcha can be consumed in a variety of ways, most commonly in the form of a beverage. In order to make matcha tea, which can be enjoyed hot or iced, simply mix the powder into your water. You can also combine matcha powder with milk, for more of a latte-type drink. 

Alternatively, you can include matcha powder in baked goods or sprinkle it over oatmeal or a healthy acai bowl. 

Matcha isn’t famous for its taste alone, it’s also popular for its health benefits. 

Matcha can be served hot or iced. You can buy matcha from your local café or make it yourself at home. (iStock)

Some of the health benefits, which are thought to stem from consumption, are as follows:

1. Full of antioxidants
2. Enhanced brain function
3. Protects the liver

1. Full of antioxidants

Matcha is full of antioxidants, including catechins, which are plant compounds found in green tea that act as natural antioxidants, according to Healthline. 

The high amount of antioxidants found in matcha can be attributed to the fact that the whole leaf is turned into a fine powder, differentiating it from other green teas, which are usually brewed from the leaves. 

The high level of antioxidants in matcha may help prevent cell damage and lower risk for certain diseases, according to WebMD. 

2. Enhanced brain function

In a study published in 2017 by PubMed per the National Library of Medicine, a group of 23 individuals were examined for how they performed different tasks aimed at measuring brain performance. 

Some of the individuals were given four grams of matcha in tea or a bar, while the control group had a placebo.

Matcha is prepared differently than the typical tea, being directly stirred into water instead of seeped. (iStock)

The study found that those who consumed four grams of matcha had improvements in attention, reaction time and memory compared to those that were given a placebo. 

Further studies are needed to solidify the idea that matcha improves brain function, as scientists have noted that the enhanced brain function could be a result of the caffeine in matcha, according to WebMD.

An average cup of matcha contains about 19 to 45 milligrams of caffeine per gram, which is about 38 to 176 milligrams of caffeine per cup on average, according to Healthline. 

For comparison, a cup of coffee has about 70 to 140 milligrams per brewed cup, according to the source. 

Matcha does contain caffeine, with the average cup ranging from between 38 and 176 milligrams. (iStock)

3. Protecting the liver

Matcha and green tea could reduce your risk of liver disease. 

In 2015, a review published by PubMed Central was done of 15 studies that found drinking green tea was associated with a decreased risk of liver disease.

In 2020, experts noted that the protective properties of matcha for the liver benefit those with nonalcoholic fatty liver disease (NAFLD), a condition where fat builds in the liver, by reducing liver enzymes, but could have the opposite impact in those without NAFLD, according to Heathline.
