Another new micronutrient has been discovered in breast milk. This is a sugar molecule called myo-inositol that promotes brain development in infants.

Researchers found that this sugar molecule is most abundant in human breastmilk early after birth when neuronal connections are rapidly forming in the infant brain. Three weeks after birth the levels found in breast milk slowly start to decrease.

This micronutrient was found in breast milk from women at all three study sites (Mexico City, Shanghai, and Cincinnati) - and at similar levels. The researchers stated that this could be one of the reasons why breast milk is so beneficial for a baby's brain development.

Interestingly, adults get myo-inositol from foods, with an adult eating a Western diet getting about 1 gram per day. It is also produced in the brain and other organs. It is especially abundant in fruits (e.g., cantaloupe and oranges), beans, grains, and nuts.

Published on Leave a comment on Study Finds Mediterranean Diet Lowers the Risk of Developing Heart Disease In Women

A recent study was good news for those wishing to lower their chances of developing heart disease (cardiovascular disease) without the use of medications. Instead, focus on the foods you eat, specifically those in a Mediterranean-style diet.

The Univ. of Sydney researchers did an analysis of 16 existing studies (with 722,495 women) and found that women following a Mediterranean diet lowered their odds of developing heart disease by 24% and lowered their risk of early death by 23%.

In this study, a Mediterranean diet meant eating a diet rich in fruits, vegetables, whole grains, legumes, nuts, seeds, extra virgin olive oil. Moderate amounts of seafood, low to moderate in wine consumption, and low in red/processed meats, dairy products, animal fat, and processed foods.

Why is the Mediterranean diet beneficial? The diet focuses on whole foods that are also rich in fiber, antioxidants, has an increased intake of all sorts of nutrients (vitamins, minerals, flavanols, etc.), less oxidative stress, it's anti-inflammatory, reduced glycemic load, boosts the immune system, and feeds the beneficial microbes in our gut microbiome.

Interestingly, studies find that frequent consumption of extra virgin olive oil (EVOO) lowers the risk of death from several diseases (heart disease, cancer, neurogenerative disease, and respiratory disease), lowers the incidence of breast cancer, and promotes healthier brain aging. A Mediterranean diet is associated with numerous health benefits (e.g., lower dementia risk) besides a lower heart disease risk.

These findings are important because heart disease is the leading cause of death globally, according to the World Health Organization. According to the CDC, it is the number 1 killer of women in the United States.

Published on Leave a comment on A Good Diet Is Associated With Lower Rates Of Miscarriage

It absolutely makes sense that a good diet before and during pregnancy is associated with better pregnancy outcomes, including the risk for miscarriage.

Researchers at the University of Birmingham reviewed 20 studies (for a total of 63,838 women) and found that a good diet with healthy foods (both preconception and during pregnancy) is linked to a lower chance of miscarriage. On the other hand, a diet high in processed foods was associated with a doubling of miscarriage risk. Interestingly, higher intake of fried foods and a lower intake of chocolate is also associated with higher miscarriage odds.

What is a "good diet" linked to lower risk of miscarriage? One that is rich in fruits, vegetables, dairy, eggs, and seafood. A high intake of fruits was linked to 61% reduction of miscarriage risk, high intake of vegetables had a 41% reduction, dairy was linked to a 37% reduction, and consumption of eggs had a 19% reduction. Seafood (fish) had a 19% reduction.

Hmmm.... overall the results sound like Mediterranean-style or healthy Nordic foods diets are beneficial. By the way, the researchers were unable to draw any conclusions regarding meat, red meat, white meat, fat, and oil.

There are many reasons for the lower rate of miscarriage with a healthy, whole foods diet: from an increased intake of all sorts of nutrients (vitamins, minerals, flavanols, etc.), rich in anti-oxidants, less oxidative stress, lower rates of inflammation, boosts the immune system, to feeding beneficial microbes in our gut microbiome.

Fun fact: the developing fetus can taste the foods the mother eats.

A preconception and early-pregnancy diet that contains lots of fruit, vegetables, seafood, dairy, eggs and grain may be associated with reducing risk of miscarriage, a new review of research suggests. ...continue reading "A Good Diet Is Associated With Lower Rates Of Miscarriage"

Published on Leave a comment on Health Risks From Popular Artificial Sweetener

Artificial sweeteners are very popular, with sucralose (Splenda) being the most widely used artificial sweetener in the US. However, there is increasing evidence that these sweeteners are linked to health problems. Recently, a study found that basically all safety claims by the manufacturer of sucralose are nonsense (deceptive advertising!), and that the sweetener instead can cause health harms.

Health harms from sucralose include: damages DNA (it's genotoxic), it causes "leaky gut" (makes the wall of the gut more permeable), bioaccumulates in the body, leukemia, alters gut microbes, drives glucose intolerance, causes weight gain, increases appetite. decreases insulin sensitivity, metabolic dysfunction, enters into breastmilk of nursing mothers, promotes intestinal inflammation, and more.

Of course the European Union has stricter standards regarding sucralose than the US. (Why am I not surprised?).

The following two articles discuss different aspects of sucralose and its health harms. The one from US Right to Know is worth reading in full.

Excerpts from Medical Xpress: Chemical found in common sweetener damages DNA

A new study finds a chemical formed when we digest a widely used sweetener is "genotoxic," meaning it breaks up DNA. The chemical is also found in trace amounts in the sweetener itself, and the finding raises questions about how the sweetener may contribute to health problems. ...continue reading "Health Risks From Popular Artificial Sweetener"

Published on Leave a comment on Eating A Diet Rich in Flavanols May Help With Memory

One fear people have is of developing problems with their memory in their later years, called age-related memory loss. A recent study finding a possible way to maintain memory in older adults is intriguing and offers hope. And best of all, it's fairly easy to do - just increase the intake of flavanol rich foods.

A large Columbia University study of adults over age 60 found that daily flavanol supplementation (cocoa extract with 500 mg flavanols) over a 3 year period improved the memory of persons whose diet was low in flavanol intake from foods, but not in persons with high intake of flavanols. The researchers suggest that a low flavanol diet is one of the drivers of age-related memory loss.

The researchers stated that flavanols only improved memory processes governed by the hippocampus, and did not improve memory mediated by other areas of the brain.

Flavanols are natural substances found in certain fruits and vegetables, especially berries, onions, kale, lettuce, tomatoes, apples, grapes, and cocoa. Flavanols are a type or class of flavonoids, all of which have health benefits. Eat a variety of plant foods (includes tea and wine) to ensure you're eating a variety of flavonoids.

Some other benefits of flavonoids: they are anti-inflammatory, anti-oxidative, have anti-mutagenic and anti-carcinogenic properties, lower heart disease death rates, and prevention of heart disease.

From Medical Xpress: Low-flavanol diet drives age-related memory loss, large study finds

Published on Leave a comment on Certain Foods Are Great For Gut Health

Another recent study confirmed that what you eat determines the microbes living in your gut (small intestines). This is the gut microbiome or microbiota (the community of bacteria, fungi, viruses). The microbes living in a person's gut can be determined by analyzing a sample of a person's poop.

The researchers found that persons eating more fruits, vegetables, and foods high in fiber (e.g., whole grains, fruits, vegetables, nuts, seeds) have gut microbes associated with health. They also have more diversity of species in the gut (this is a sign of health). But eat a diet rich in highly processed foods and low in fiber, and you'll have microbes associated with health problems (e.g., heart disease, cancer, diabetes).

The researchers point out that following the recommendations of the Dietary Guidelines for Americans (DGA) supports a healthy gut microbiome. Especially important for a healthy gut microbiome were vegetables, whole grains, legumes, and dairy. Yes, dairy foods have oodles of microbes (your cheese is alive!), whole fat dairy is beneficial, but skim milk or 0% is not. Eating a variety of high fiber foods is important because then you'll be eating a variety of fibers.

Bottom line: you are what you eat.

Excerpts from Medical Xpress: How diet quality affects the gut microbiota to promote health

We know that eating a healthy diet affects body weight, cholesterol levels, and heart health. A new study from the University of Illinois focuses on another component: the role of diet in supporting a healthy gastrointestinal microbiota. The researchers conclude that following the Dietary Guidelines for Americans (DGA) promotes a gut microbiota composition that may support overall health. ...continue reading "Certain Foods Are Great For Gut Health"

Ready to eat some insects for your gut health? Hah! A recent research paper made the case that eating insects will improve the gut microbiome and health.

The researchers point out that eating insects already happens throughout the world. Edible insects are good sources of protein, micronutrients, and contain dietary fiber and omega-3 fatty acids. Also, insects can be farmed using fewer resources than conventional livestock (e.g., beef, pigs)

The most commonly consumed insects: beetles, caterpillars, wasps, bees, ants, grasshoppers, true bugs; and termites.

From Science Daily: Chitin from consuming insects can help both gut microbiota and global health

Chitin (kai'tin) and healthy fats from insects appear to contribute to healthy gut microbiota and are strong sources of protein and nutrients, according to a paper co-authored by a Colorado State University researcher and published in Nature Food. ...continue reading "Are You Ready to Eat Insects?"

Published on Leave a comment on Plant-Based Copies of Meat and Dairy Are Not the Same Nutritionally As Real Milk and Meat

Not all foods are equal. Especially dairy milk vs alternative "milks", such as almond or oat milks. Or plant-based "meat" vs animal meat. A recent study analyzed popular plant-based "milk" and "meat" products and found that they are not nutritionally equivalent to real milk and meat.

They contain different nutrients, amount of protein, calories, etc. The researchers concluded that eating only or mainly the plant-based substitutes can result in dietary deficiencies  - that is, of nutrients found in meat and dairy.

Meat and dairy products are good sources of vitamin B12, zinc, iodine, long-chain omega fatty acid, and choline. All of these are necessary for good health. Eating cheese (a dairy product) such as Jarlsberg cheese is great for bone health because of the microbes (Proprionebacterium freudenreichii) living in the cheese  and which produce vitamin K and DHNA (both necessary for bone health).

Instead of eating fake substitutes (many of which are highly processed, with lots of additives), why not focus on eating more real plant-based foods? This means eating more whole grains, seeds, nuts, legumes (beans), fruits, vegetables, and then just reduce the amount of meat and dairy eaten.

From Medical Xpress: Switching meat and milk for plant-based copies misses vital nutrients

Mitigating climate change is a key challenge of our time. One way many people try to reduce their greenhouse gas emissions is to eat less animal-source food—like meat and dairy—and instead eat more plant-based food. ...continue reading "Plant-Based Copies of Meat and Dairy Are Not the Same Nutritionally As Real Milk and Meat"

Published on Leave a comment on Some Harmful Food Additives Could Finally Be Banned

Finally... two states (California and New York) are seeking to ban 5 chemicals frequently added to food that are known to cause health problems (cancer, neurological problems, hormone disruptors). They have no reason to be in food (and yes, safer alternatives exist). The five chemicals of concern are: red dye 3, titanium dioxide, potassium bromate, bromated vegetable oil, and propylparaben.

These additives are most commonly found in candy, baked goods, and soda. They are already banned in Europe. Once again the FDA is not protecting consumers, while Europe is way ahead of the US in protecting consumers. Of course the chemical industry is pushing back ($$ before consumer health!).

The bills are AB-418 Food product safety (California) and Bill S6055A - Prohibits certain food additives and food color additives (New York). If approved, both would go into effect in 2025.

Bottom line: Read ingredient lists on labels and avoid these 5 ingredients, plus as many other additives, preservatives, colors, artificial or natural flavors (all laboratory concoctions) as you can. Avoid ultra-processed foods and high-fructose corn syrup as much as possible. Best are ingredients that we all have in our kitchens.

Published on Leave a comment on Magnesium Is Important For Brain Health

Another important nutrient for brain health is magnesium. A recent study found that ingesting higher levels of magnesium from foods (dietary magnesium) is associated with better brain health and brain volume. Brains normally shrink a little with age, but ingesting higher levels of dietary magnesium resulted in less age-related shrinkage.

The researchers found that the effects were especially beneficial for postmenopausal women. It is important to note that all study participants had recommended or higher levels of magnesium intake from foods. No one had a magnesium deficiency. Recommended dietary allowances are 400–420 mg for men and 310–320 mg for women - but the results from this study suggest that ingesting even more from foods is better.

In other words, consider magnesium important for a healthy brain. Try to increase intake of magnesium rich foods. The researchers point out that recent studies suggest that dietary magnesium is associated with better cognitive function and may reduce the risk of dementia.

Foods rich on magnesium: pumpkin seeds, almonds, spinach, cashews, pumpkin seeds, chia seeds, peanuts, shredded wheat cereal, quinoa, soymilk, black beans, edamame, dark chocolate, bread, whole wheat, avocado, potato, nuts, bananas.
