Three recent large and well-controlled studies showed that omega-3 fish oil pills did not prevent heart attacks or surgical procedures for heart disease in people at high risk for heart attacks, while one study showed reduced heart disease.
Researchers followed 104,760 participants and found that people who drink large amounts of either sugared drinks or artificially sweetened beverages are at increased risk for developing new heart disease such as stroke, transient ischemic attacks (TIAs), heart attacks or acute coronary syndrome
A study of 20 healthy, normal-weight people found that changing their evening meal from 6PM to 10PM significantly increased their markers for becoming obese and developing diabetes.
Overweight people who lose weight without dieting after age 65 are at high risk for dementia. Excess weight is a major risk factor for dementia.
In the last year, I have seen two experienced cyclists who suffered recurrent numbness and tingling of their hands when they rode long distances. Both had low blood levels of vitamin B12 and one was cured by taking 1000 mcg per day of vitamin B12 pills, the other by eating fish.
Taking sugared drinks in any form increases risk for heart attacks, but exercise may offset some of the damage. Exercise increases blood flow in people who have even severe blockage of their arteries leading to significant heart disease.
No drugs, supplements or potions have been shown to extend your life, in spite of the fact that the internet is full of an incredible number of fraudulent life-extension products that provide no benefits while they steal your money. However, we do have overwhelming evidence that several healthful lifestyle habits can extend how long you live and improve your quality of life in your later years.
Coconut oil does not help a person lose weight, lower blood sugar levels, or dampen down harmful inflammation (Circulation, Jan 13, 2020). The authors reviewed 17 studies and found that coconut oil increased blood levels of the harmful LDL cholesterol much more than the increase from soybean, olive, safflower, canola or palm oils.
Probiotics are foods or supplements containing healthful bacteria that pass to your colon when you eat them. The National Center for Complementary and Integrative Health reports that close to four million adults in the U.S. use probiotics.
The main argument for drinking milk is its high calcium content. Milk and cheese contribute 46 percent of the calcium intake by the average American, but researchers have found many recent studies showing that American adults do not need to take in that much milk to provide enough calcium to help prevent bone fractures.
If you are trying to control your weight, you should not skip breakfast because the food that you eat in the morning causes you to burn more than two and a half times as many calories as the food you eat at night.
A recent study in mice showed that increasing dietary protein from 15 percent to 46 percent of calories caused the mice to develop 30 percent more arterial plaques than mice on their normal-protein diet, even though they did not gain more weight.
A study of 5571 adults found that people who have higher blood levels of vitamin B12 are more likely to die prematurely. Compared to those with lower B12 blood levels, people with higher B12 levels were likely to be fatter and have higher blood pressure, higher cholesterol, and higher blood sugar.
Two new studies add to the huge body of research showing that perhaps the most important dietary recommendation is to eat lots of fiber, which is found in plants. You keep on gaining health benefits until you reach at least 25 to 29 grams of fiber per day.
North Americans eat far more fat than they need, primarily from the vegetable oils that are added to just about every packaged food or fast food meal you can buy, and from our tendency to cook most of our foods in fat. It is harmful to take in a lot of fats from vegetable oils because excessive fat intake can cause high insulin levels and insulin resistance, which can cause diabetes.
Egg yolks are among the richest food sources of cholesterol, and almost 100 million North American adults have high blood cholesterol levels, signifying increased risk for heart attacks. Most of the cholesterol in your body is made by your liver and less comes from the food that you eat.
In a recent study of time-restricted eating, a group of 19 people with metabolic syndrome (also called pre-diabetes) ate their usual meals but ate only between 8AM and 6PM (10 hours) and took in no calories during the other 14 hours each day.
Researchers at the U.S. Centers for Disease Control and Prevention (CDC) found that for every five percent increase in calories from ultra-processed foods, there is increased risk for heart attacks and strokes. Taking in 70 percent of calories from processed foods doubles heart attack risk factors.
Two companies -- Impossible Foods and Beyond Meat -- dominate the market for plant-based burgers that taste like meat. A major concern is that these products have not been tested for long-term safety.
It is well-known that taking large doses of the fat-soluble vitamins -- A, D, E and K -- can harm you. You may also be harmed by large doses of the water-soluble B vitamins or vitamin C.
Don't believe the recent headlines suggesting that people can continue to eat their usual amounts of meat without suffering any increase in risk for illness or premature death.
