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.

Published on Leave a comment on Eating Healthy Foods Lowers Risk of Chronic Diseases

Want to improve your odds of not getting a chronic disease, such as heart disease or diabetes? A recent study found that following any healthy dietary pattern, whether Mediterranean or DASH or Diabetes Risk Reduction Diet or other similar healthy dietary styles, are all linked to a lower risk of chronic diseases.

These healthy dietary patterns all stress fruits, vegetables, whole grains, seeds, nuts legumes, but they vary in minor ways, e.g., whether salt, coffee, tea, or wine is allowed. People weren't following specific diets over the 3 decades of the study, but it's how they generally ate - their dietary pattern.

The Harvard T.H. Chan School of Public Health researchers found that persons who were in the top 10% of a healthy dietary pattern, no matter which one, were compared to persons in the bottom 10% of that dietary pattern. Overall they found that being near the top of any of the healthy dietary patterns was associated with a lower disease risk.

Interestingly, larger amounts of coffee, whole grains, wine and desserts had lower risk of associated major chronic diseases.

Eating some foods frequently were associated with developing major chronic diseases, such as processed meats, energy drinks, french fries, red meat, and eggs.

Published on Leave a comment on A Mediterranean Style Diet Is Associated With A Lower Dementia Risk

Another large study found that eating a Mediterranean diet is beneficial to health - specifically, that it is associated with a decreased risk for dementia. As much as 23% lower (compared to those who didn't eat a Mediterranean style diet)! It didn't matter if a person had a genetic risk for dementia or not - diet was more important.

By the way, other studies also find that eating a Mediterranean style diet has benefits for the brain and body.

A Mediterranean style diet is one rich in fruits, vegetables, whole grains, legumes (beans, lentils), nuts, seeds, herbs, spices, and olive oil. Some lean meat, especially chicken, and fish. This way of eating is high in fiber (good for health!). Try to avoid processed meats, highly processed foods, fast food, and hydrogenated oils. Eat less meat in general.

Experts at Newcastle University found that individuals who ate a Mediterranean-like diet had up to 23% lower risk for dementia than those who did not. ...continue reading "A Mediterranean Style Diet Is Associated With A Lower Dementia Risk"

Published on Leave a comment on Six Lifestyle Habits Associated With Less Memory Decline In Older Adults

Memory declines over the years as we age. For some it can be mild (being forgetful), but very severe for some others.  The good news is that there are things we can all do to prevent, slow, or even reverse (!!) the memory decline. Studies suggest the key is adopting healthy lifestyle habits.

A large study found that there are six healthy lifestyle habits that were linked to a slower decline in cognitive decline (memory) in older adults followed for a decade. The more healthy habits, the slower the memory decline. The average age of participants was 72 years when the study started.

The six healthy lifestyle habits are a healthy diet, cognitive activity (use your brain!), regular physical exercise, not smoking, and and not drinking alcohol. Having a healthy diet (e.g., Mediterranean style diet) was the most important thing one can do, followed by cognitive activity (e.g., reading, writing, playing cards) and physical exercise or activity.

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.

Published on Leave a comment on Walking Is A Good Treatment For Knee Arthritis

Walking may be the best way to deal with arthritis pain in the knees (knee osteoarthritis) and to slow its progression. Yes, rather than resting arthritic knees, the best treatment appears to be walking.

A study of individuals over the age of 50 found that walking for exercise prevented flare ups of arthritis knee pain from becoming persistent pain. This might be because consistent movement can help create muscle mass, strengthening ligaments around the joints that have osteoarthritis.

The study also found that walking for exercise is an effective way to slow the damage that occurs within the knee joint. Who would have guessed?

From Science Daily - Walking Towards Healthier Knees

A new study published in Arthritis & Rheumatology led by researchers at Baylor College of Medicine reveals that walking for exercise can reduce new frequent knee pain among people age 50 and older diagnosed with knee osteoarthritis, the most common form of arthritis. Additionally, findings from the study indicate that walking for exercise may be an effective treatment to slow the damage that occurs within the joint. ...continue reading "Walking Is A Good Treatment For Knee Arthritis"

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 Crossword Puzzles Are Good For the Brain

One of the fears about aging is the possibility of developing dementia. Even in healthy older adults it is normal for the brain to slowly shrink with increasing age, and thinking processes can deteriorate. A recent study lasting 78 weeks offers hope to persons already diagnosed with mild cognitive impairment (MCI).

In older adults with MCI, there is an increased risk it can progress to dementia, especially Alzheimer's disease. Studies are finding that doing complex mental activities that stimulate the brain may decrease the risk of cognitive decline and dementia.

In this study, researchers found that doing crossword puzzles was better than doing computer games in improving memory loss and thinking processes, and slowing the progression of decline in persons already diagnosed with MCI. The crossword puzzle group also showed less decline in daily activities, and MRIs showed fewer decreases in brain size (hippocampal volume and cortical thickness).

Persons (average age 71.2 years) were randomized to either of the groups, and they did the online games or crossword puzzles (provided by Lumos Labs) at home. Total time spent each day: 30 minutes four times per week.

Are online crossword puzzles better than computer games for persons without any cognitive impairment?  This is where it gets interesting - the answer is no. One study found that computer games were better in a group of 18 to 80 year olds, even though doing either results in improvement.

By the way, numerous "brain training" claims by a computer mind games company such as Lumos Labs were viewed as deceptive by the FTC ($2 million fine back in 2016 for all sorts of unsupported claims).

What to do for brain health? The reality is that activities that stimulate the mind (reading, art, computer games), getting vaccines in adulthood, and exercise/physical activity are all good for the brain. And of course, eating well (especially more fruits, berries, nuts, and eggs) and getting enough sleep. Avoid anticholinergic medicines and smoking.

Mild cognitive impairment (MCI) can even improve on its own without any special treatments - even in adults 65 years or older.

Published on Leave a comment on Sleeping Less Than Five Hours A Night Ups the Risk For Health Problems

Many of us do not get enough sleep at night. Unfortunately, this is bad for our health. Another large study just confirmed this - they found that consistently getting 5 or fewer hours per night during mid-life or later in life is linked to developing several diseases.

Sleeping 9 or more hours at 60 or 70 years of age (but not at age 50) was also associated with developing multiple chronic diseases. No association was found between sleep duration and early death among those with existing chronic diseases.

The study, conducted in the UK, looked at sleep amounts in more than 7000 persons over a 25 year span (when they were 50, 60, and 70 year old). Persons with short sleep duration (5 or fewer hours) had a higher risk of developing not just one chronic disease, but multiple chronic diseases.

The possible chronic diseases were: diabetes, cancer, coronary heart disease, stroke, heart failure, chronic obstructive pulmonary disease (COPD), chronic kidney disease, chronic liver disease, depression, dementia, mental disorders, Parkinson's disease, arthritis/rheumatoid arthritis.

Published on Leave a comment on Large Study Finds Women Have Better Verbal Abilities Throughout Life

People have been saying this for years, but now a big study confirmed it: women and girls are better than men and boys at verbal fluency and remembering words. The difference may be small, but it is consistently there over the lifetime.

In other words, women have better verbal abilities. By the way, girls generally start talking earlier and with more complex speech than boys.
