Say it over and over to yourself: Don't eat highly processed foods, don't eat foods with additives (e.g., emulsifiers, colors), don't eat foods/beverages with high fructose corn syrup, don't eat lots of pre-packaged foods or fast foods.

Why? This kind of high fat, low-fiber Western diet (which most of us eat), is linked to lots of health problems  and also an unhealthy gut microbiome. Cancer, diabetes, heart disease!

Instead, eat a Mediterranean style diet - a diet rich in fruits and vegetables, whole grains, seeds, nuts, whole grains, legumes. Also, lots of olive oil. This is a high fiber diet linked to good health and a healthy gut microbiome.

Research finds harms (e.g., harmful alterations of the gut microbiome or intestinal lining, cancer) from ingredients added to highly processed foods, such as emulsifiers, carrageenan, artificial sweeteners, maltodextrin, carboxymethyl cellulose, polysorbate-80, artificial colors and flavors, high fructose corn syrup, etc. Bottom line: Try to avoid any ingredient that's not normally in your kitchen! Read ingredient lists on labels.

Excerpts from a commentary (transcript of podcast) by Dr. D. Johnson from Medscape: Forget Fad Diets, Here's the One You Need

Hello. I'm Dr David Johnson, professor of medicine and chief of gastroenterology at Eastern Virginia Medical School in Norfolk, Virginia. Welcome back to another GI Common Concerns.

All of us routinely see diet recommendations on the Internet — like TikTok — or in new books. Every possible diet seems to receive this promotional push, although the evidence behind them is often lacking.

So what do we mean when we talk about a "healthy diet"? ...continue reading "Doctors Recommend Mediterranean Style Diet For Health"

Published on Leave a comment on Some Foods With Organic Labels Are Not So Organic

There is a big problem with the label ORGANIC. Many organic farmers are upset and disappointed with how "organic factory farms" have taken over the multi-billion organic food industry. And they should be upset.

Organic foods are foods grown and processed following organic farming standards (rules). But... Big Business (who support factory farms) has influenced the organic rules and has found all sorts of loopholes which they use. This is not for the better for the farmer or consumer.

Ethical organic farmers are paying the price. Doing organic correctly (e.g., cows actually graze outdoors, berry crops actually grown in soil) costs more than factory farming which ignores organic rules (e.g., stuffing thousands of animals into buildings without any real access to outdoors). So... the smaller organic farmers actually following the spirit of organic standards can't compete with factory farms and are being forced out of farming.

Also, much "organic" food and products coming from countries such as China and Turkey are NOT organic - the label is a total fraud. That is why their "organic" is so cheap compared with North American and European  grown organic food.

Organic farmers are now fighting back by developing labels that distinguishes their food and products as "real" organic - organic how it's meant to be. For example, the animals receive organic feed from the start, do go outside, and crops are grown in soil (and not artificially in water filled containers). A new label gaining popularity is Real Organic Project. So far over 1000 US farms have joined.

What you can do: Go check out farmers markets and support small farms. Buy organic food that is known to support real organic practices (e.g., Organic Valley - a co-op of organic farmers) rather than factory farmed food (e.g., Horizon, Aurora).

Written by organic blueberry farmer Hugh Kent, from Mother Earth News: Real Organic Project: Is “USDA Organic” Really Organic?

Is “USDA Organic” Really Organic?

Many of us who want good, healthy food look at labels in hopes they’ll help us evaluate our food and its quality. We’ve turned with hope to terms like “all-natural,” “sustainable,” and, lately, “regenerative,” but none of these has an established or consistent meaning. In the U.S., the word “organic” stands alone as a term defined by law. “Certified Organic” can only be used if the product complies with the law (which emphasizes the enhancement of soil quality as its foundational principle). ...continue reading "Some Foods With Organic Labels Are Not So Organic"

Published on Leave a comment on Study Finds Calorie Intake More Important Than Timing of Meals For Weight Gain or Loss

scale, weightThere has been a debate going on for a while about what is better for weight loss: intermittent fasting (eating only during designated time periods, without calorie counting) or actually cutting back calories. One recent study examined this issue and found that...drum roll.... the frequency of meals (and calories) a person eats every day is more important for weight loss than intermittent fasting.

Main finding: Large or moderately sized meals (no matter when eaten) were associated with weight gain over the 6 year period of the study, while eating fewer, small meals were associated with weight loss. In other words, the number of meals eaten each day and meal sizes (calories), and not their timing, was most important in determining weight gain or loss.

The results did not support intermittent fasting (time-restricted eating) as a weight loss strategy. Instead, focus on calorie intake. Bummer... You didn't think it would be easy, did you?

Excerpts from Science Daily: Reducing total calories may be more effective for weight loss than intermittent fasting

The frequency and size of meals was a stronger determinant of weight loss or gain than the time between first and last meal, according to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association. ...continue reading "Study Finds Calorie Intake More Important Than Timing of Meals For Weight Gain or Loss"

Published on Leave a comment on The Nutrient Choline Is Necessary For Brain Health

Choline appears to be a neglected nutrient. It is essential for healthy brain functioning, yet researchers of a recent study say the great majority of us do not get the recommended daily intake of choline in our diet. They suggest that this could be causing harm to our health, including the brain.

They also pointed out that since eggs and meat are the best dietary source, people on restricted or vegan diets are especially at risk of a choline deficiency. It is not found in most multivitamins.

The  Arizona State Univ. researchers found that choline deficiency is involved with multiple health problems throughout the body (e.g., inflammation, insulin production, cardiovascular disease, brain function) and even Alzheimer's disease. Their study was conducted on mice, but they felt similar processes occurred in humans.

Good dietary sources of choline: eggs, meat, dairy products, poultry, and fish. Lower amounts are in nuts, beans, potatoes, and cruciferous vegetables (e.g., broccoli).

Related to all this is that one should also try to lower intake of anti-cholinergic medications, if possible. Studies find that their use is linked to cognitive decline and dementia - they block the action of the brain neurotransmitter acetylcholine (which is produced by choline).

Excerpts from Science Daily: Study explores effects of dietary choline deficiency on neurologic and system-wide health

Choline, an essential nutrient produced in small amounts in the liver and found in foods including eggs, broccoli, beans, meat and poultry, is a vital ingredient for human health. A new study explores deficiency in dietary choline adversely affects the body and may be a missing piece in the puzzle of Alzheimer's disease.  ...continue reading "The Nutrient Choline Is Necessary For Brain Health"

Published on Leave a comment on Study Finds Vitamin D Supplements are Linked to Lower Risk of Melanoma

The results from well done studies on vitamin D supplements have frequently been disappointing due to lack of health benefits. However, a recent study found that the risk of melanoma (a skin cancer) was significantly reduced in persons taking vitamin D supplements.

The Univ. of Eastern Finland researchers also found no link between vitamin D supplementation and facial photoaging, actinic keratoses, nevus count, basal cell carcinoma and squamous cell carcinoma.

Just keep in mind that the people were not randomly selected  - these were self-selected groups, and thus this is a correlation study. There could be a reason other than vitamin D for the different outcomes.

From Science Daily: Fewer cases of melanoma among people taking vitamin D supplements

Fewer cases of melanoma were observed among regular users of vitamin D supplements than among non-users, a new study finds. People taking vitamin D supplements regularly also had a considerably lower risk of skin cancer, according to estimates by experienced dermatologists. The study, conducted in collaboration between the University of Eastern Finland and Kuopio University Hospital and published in Melanoma Research, included nearly 500 people with an increased risk of skin cancer. ...continue reading "Study Finds Vitamin D Supplements are Linked to Lower Risk of Melanoma"

The results of a recent study may give extra motivation to those trying to cut back on the amount of fast food that they eat. The study found that consumption of fast food is linked to nonalcoholic fatty liver disease (NAFLD).

The researchers found moderate increases in liver fat in everyone consuming  20% or more of daily calories from fast food (about 1 meal a day). They also found that obese individuals or people with diabetes who consume 20% or more of their daily calories from fast food had severely elevated levels of fat in their liver.

We already know that fast foods are associated with a greater risk of diabetes and heart disease, and now NAFLD can be added. It is thought that NAFLD affects 30% of the U.S. population!

According to the US National Institute of Health: "Nonalcoholic fatty liver disease (NAFLD) is a condition in which fat builds up in your liver. Nonalcoholic fatty liver (NAFL) and nonalcoholic steatohepatitis (NASH) are types of NAFLD. If you have NASH, you have inflammation and liver damage, along with fat in your liver."

What to do about this abnormal build up of fat in the liver? The only treatment is changing your diet and losing weight. A healthy diet is one rich in fruits, vegetables, legumes, whole grains, seeds, and nuts. For example, a Mediterranean style diet.

From Science Daily: Consumption of fast food linked to liver disease

A study from Keck Medicine of USC published today in Clinical Gastroenterology and Hepatology gives people extra motivation to reduce fast-food consumption. ...continue reading "Fast Food and Liver Disease"

Published on Leave a comment on Drinking Tea Every Day Has Health Benefits

Some good news. A study found that frequent consumption of foods and beverages containing flavonoids by elderly women had health benefits. Flavonoids are compounds found naturally in plants, and that have health-promoting effects.

The 881 women (aged 78 to 82 years) in the Australian study were less likely to have abdominal aortic calcification (AAC) if they ingested high levels of flavonoids in their diet. This is significant because AAC is a major predictor of cardiovascular disease events, such as heart attacks, strokes, and death.

Drinking black tea daily was their major source of flavonoids. Drinking 2 to 6 cups a day lowered the risk of having extensive AAC.

Good flavonoid sources are: black tea, green tea, wine, apples, nuts, citrus fruits, berries, grapes, onions, broccoli, kale, parsley, and dark chocolate. There are different types of flavonoids, each with different health-promoting effects. This is why it's good to eat a variety of fruits and vegetables.

Published on Leave a comment on A Dietary Supplement That Might Increase Cancer Risk

Some dietary supplements can do serious harm, especially when taken in high doses. A recent study found cancer associated with high doses of the supplement nicotinamide riboside (NR), which is a form of vitamin B3.

Keep in mind that this study was done in vivo and in vitro (in a lab), and also in mice.. and not humans. But the results are concerning.

Swiss and Univ. of Missouri researchers found that high levels of NT could increase the risk of developing triple-negative breast cancer, and also for it to metastasize to the brain. Yikes.

By the way, while NR can be purchased as a supplement, it is normally not found in ordinary multi-vitamins that many take daily. Low levels of NR are found in fruit, vegetables, meat, and milk - it is necessary for health (it increases levels of cellular energy). It's the large amounts found in supplements that the researchers were concerned with and that can be problematic.

Stay tuned for further research...

From Science Daily: Popular dietary supplement increases breast cancer risk, brain metastasis, study suggests

While previous studies have linked commercial dietary supplements like nicotinamide riboside (NR), a form of vitamin B3, to benefits related to cardiovascular, metabolic and neurological health, new research from the University of Missouri has found NR could actually increase the risk of serious disease, such as development of breast cancer and brain metastasis. ...continue reading "A Dietary Supplement That Might Increase Cancer Risk"

Great news for those who like honey! Even though honey is really sweet (lots of sugars!), eating it actually helps your health. Univ. of Toronto researchers analyzed 18 well done studies and found that honey improved key measures of cardiometabolic health, including blood sugar and cholesterol levels.

These results are interesting because they contrast with other research finding a high intake of sugars (e.g., sugar, high fructose corn syrup, soda) contributing to obesity, type 2 diabetes, and cardiovascular disease. Unfortunately, most regulatory agencies, including the World Health Organization, the Heart and Stroke Foundation, and the FDA (US Food and Drug Administration), include honey within their definition of free or added sugars. And advise limiting intake.

However, honey is not like other sugars. Honey has a complex composition of organic acids, minerals, vitamins, enzymes, proteins, amino acids, and bioactive substances. Rare sugars constitute around 14% of the sugar content of honey. Raw honey also contains probiotic bacteria.

All sorts of studies (in vitro, animal, clinical) have shown that honey has health benefits for cardiometabolic health. Among these benefits are improvements in body weight, inflammation, lipid profile, and glycemic control.

What kind is best? The Univ. of Toronto researchers found that the best health results are found with consumption of raw honey, clover honey, and robinia honey. In other words, honey that is not processed (raw honey) or from only 1 floral source (e.g., clover, acacia/robinia).

How much is best? The median dose consumed was 40 g or about 2 tablespoons daily, usually added to foods or beverages as a sweetener (e.g., in tea, mixed with yogurt, spread on bread) . Enjoy!

Researchers at the University of Toronto have found that honey improves key measures of cardiometabolic health, including blood sugar and cholesterol levels -- especially if the honey is raw and from a single floral source.  ...continue reading "Study Finds Health Benefits From Eating Honey"

All of us should be concerned about harmful health effects from a sedentary lifestyle, along with drinking lots of sugary soda. However, according to a (very) small study, ten days of adopting this lifestyle seems to have more of a negative effect on healthy young men than on women, at least in the short term.

Even just 10 days of reducing physical activity (from greater than 10,000 steps to less than 5000 steps per day) and increasing soda intake (to 6 cans a day!) was enough to have a negative effect on insulin levels (vascular insulin resistance) in healthy young men. But the Univ. of Missouri researchers found no real effect on the young women.

From Medical Xpress: Sedentary lifestyle and sugary diet more detrimental to men, study finds

A new study from the University of Missouri School of Medicine is the first evidence in humans that short-term lifestyle changes can disrupt the response to insulin of blood vessels. It's also the first study to show men and women react differently to these changes. ...continue reading "Ten Days of Unhealthy Lifestyle Has Greater Effect on Young Men than Women"
