A recent news headline proclaimed, "An Egg a Day May Keep Heart Disease Away" (Time, May 21, 2018), based on a study of 512,891 adults in urban and rural areas of China. Those who ate one egg a day were reported to have an 18 percent reduced incidence of heart attacks and an incredible 26 percent reduction in bleeding strokes.
Restricting calories, even in non-obese people, reduces inflammation, helps to prevent cancers and increases autophagy. Autophagy or cellular recycling extends the lives of many different species. Autophagy means "self-eating." When a cell dies, the body has a quick way to break down the dead cell’s parts (protein-making, power-generating and transport systems) into small molecules that can be reassembled to be used for making new cell parts.
Gluten is a group of proteins found in wheat, rye and barley that causes about two percent of North Americans to become sick: those with celiac disease or gluten allergies. In spite of all its bad publicity from authors of popular diet books, gluten may actually offer health benefits to the remainder of the population.
Sugared drinks are associated with increased risk for obesity, diabetes, heart attacks, certain cancers and premature death (J Am Coll Cardiol, 2015;66(14):1615-1624). Yet Coca Cola has given more than 118 million dollars to prestigious health research institutions, athletic groups, disease foundations, cancer and diabetes organizations and university researchers over the last five years. These...
Fats are classified by their chemical structures into saturated, polyunsaturated and monounsaturated types. The chemical stability of a fat is determined by its structure. All fats are made of carbon atoms held together by electrical bonds. These bonds can be single bonds that are stable and double bonds that are far less stable. The stability of a fat or oil depends on the number of double bonds between the carbon atoms. The more double bonds, the less stable the fat.
I have reported before on TMAO (trimethylamine N-oxide) that is produced by certain bacteria in your gut when you eat foods that contain lecithin, carnitine and choline, such as meat, eggs and dairy products. High levels of TMAO in the bloodstream have been associated with increased risk for heart attacks, strokes, clots, diabetes and certain cancers.
Many scientific studies show that eating whole fruit is healthful, even for people who are diabetic. However, this month I learned that some people, especially those who are overweight, prediabetic or diabetic, may be harmed by eating very large amounts of fruit.
Sugar-added to foods, but not in whole fruits, increases risk for diabetes, heart attack and premature death, according to a new summary of animal and human studies, clinical trials in humans and epidemiological human population studies (Mayo Clinic Proceedings, published online January 29, 2015). The report shows that adding sugar to foods and processing...
This week, a study from Spain adds to the evidence that eating any type of meat (red, white processed, cured or organ meat) is associated with increased risk of colon cancer, and that cooking and processing meat increases risk.
A new study from the University of Southern California shows that restricting calories just five days a month for three months: • helped people lose weight, • reduced a number of risk factors for cancer, diabetes and heart attacks, and • improved markers for living a longer life and tests for immune function (Cell Metabolism, published online June...
The PURE (Prospective Urban Rural Epidemio.logy) Study, reported at the European Society of Cardiology Congress in Munich on August 28, 2018, concludes that increasing intake of fruits, vegetables, nuts, legumes, fish, dairy and non-processed red meat is linked to reduced death rate and reduced incidence of heart attacks in three data sets. However, I hope that you do not use these results as a reason to increase your intake of meat.
Wheat Belly by Dr. William Davis and Grain Brain by Dr. David Perlmutter are two best-selling books that tell you to avoid wheat and other grains. Dr Davis claims that wheat makes you fat and causes many diseases, and by eliminating wheat you will lose weight and prevent these diseases. Actually, he proposes a low-carbohydrate diet that may cause you to lose weight, but he does not have data to show that it helps you keep that weight off over time. He and Dr. Perlmutter both claim that avoiding wheat cures diseases, but they have no data to support these wild claims . . .
Hundreds of studies done in the last 15 years have shown how your microbiome (gut bacteria) helps you to retain your health, and that what you eat determines the ratio of healthful to harmful types of bacteria in your colon. These bacteria govern your immune system that determines, to a large degree, what diseases you will develop and how long you will live.
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.
The United States Public Health Service says that alcohol kills more than 88,000 people in the United States each year, and has shortened the lives of those who died by an average of 30 years. Alcohol also causes one in 10 deaths among working-age adults aged 20-64 years and the health damage it causes costs $223.5 billion, or $1.90 per drink.
The European Food Safety Authority has just released a 120-page report reviewing the health benefits and risks of coffee and advises against drinking more than four cups of coffee per day. The U.S 2015 Dietary Guidelines Advisory Committee recommends close to the same limit.
We have known for a long time that high-fiber foods such as vegetables, fruits and seeds are associated with lower risk for heart attacks, strokes, many cancers, obesity, type 2 diabetes, dementia and other diseases. Recent studies on gut bacteria are helping to explain why fiber-rich foods are beneficial.
For many years I have recommended oatmeal as the ideal breakfast food. It is filling, does not cause a high rise in blood sugar and is an excellent source of soluble fiber. You can enhance the flavor and nutritional value of your oatmeal by adding your choice of nuts, raisins or other dried fruits,
Researchers at Boston University and Harvard reviewed three studies following more than 225,000 adults over age 50, for eight to twenty years, and showed that being even slightly overweight can increase your risk of dying by six percent, and in those who are obese, by a whopping 73 percent (Annals of Internal Medicine, April...
Advertisements for products such as coral calcium or alkaline water claim that they will neutralize acid in your bloodstream, but eating calcium or drinking alkaline water does not affect blood acidity. You should not believe that it matters whether foods are acidic or alkaline, because no foods change the acidity of anything in your...
Virtually all scientists agree that North Americans need to reduce their intake of sugar, but their views on artificial sweeteners are not as clear. Increasing evidence is showing that artificial sweeteners are not benign substitutes for sugar. In a new study, people who took sucralose (an artificial sweetener) for just one week developed signs of insulin resistance and diabetes.
Obese people who have taken aspartame or saccharin in the last 24 hours had higher blood sugar rises after taking sugar than those who had not used artificial sweeteners. Lead author Dr. Jennifer Kuk says, "Our study shows that individuals with obesity who consume artificial sweeteners, particularly aspartame, may have worse glucose management than those who don't take sugar substitutes."
Researchers from Denmark performed a detailed survey of studies published between 2005 and 2015 on the associations between egg consumption, cardiovascular diseases and type 2 diabetes.. They concluded that "up to seven eggs per week can safely be consumed, but in patients with established cardiovascular diseases or type 2 diabetes, only with special emphasis on a prudent diet and proper medical treatment."
Our hunter-gatherer ancestors spent all their waking hours scrounging for food and trying to keep from starving to death. They developed a taste for the most calorie-dense foods that satisfied best, such as honey, meats and starchy roots.
A review of 83 scientific studies covering almost 600,000 current alcohol drinkers in 19 higher-income countries shows that men and women who take in as few as six drinks a week (100 grams of alcohol) are at increased risk for death from strokes, heart failure, heart disease and aortic aneurysms, but not heart attacks.
Most doctors tell patients suffering from osteoporosis to increase their intake of calcium, but the scientific literature shows that calcium pills do not help to prevent or treat bone fractures. This implies that you should get your calcium from foods rich in that mineral. A review of the scientific literature found 18 articles following 363,557 participants for 3 to 23 years showing that yogurt and cheese, but not milk or cream, are associated with decreased risk for hip fractures.
