How Much Water Do You Need?

Do you believe that a person needs to drink eight glasses of water every day? If you do, you will spend a lot of time running to the bathroom.

How Much Alcohol is Safe?

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.

Do You Need Vitamin D Pills?

North Americans spent more than $936 million on vitamin D pills in 2017, doctors ordered more than 10 million laboratory tests for vitamin D for Medicare patients at a cost of $365 million in 2016, and 25 percent of older adults take vitamin D supplements. A Kaiser Health News investigation recently reported that the man most responsible for the obsession with vitamin D pills, Boston endocrinologist Michael Holick, has been paid hundreds of thousands of dollars by supplement and drug manufacturers, the indoor-tanning industry and commercial laboratories that run blood tests for vitamin D.

Cheese and Yogurt May Help to Prevent Fractures

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.

No Simple Cure for Obesity

More than 70 percent of North American adults are overweight, which increases risk for high blood pressure, heart disease, diabetes and premature death. A review of 45 trials of 11 weight loss programs (Weight Watchers, Jenny Craig, Nutrisystem, HMR [Health Management Resources], Medifast, OPTIFAST, Atkins, The Biggest Loser Club, eDiets, Lose It! and SlimFast) showed that most had no good long-

Why We Use Intermittent Fasting

Intermittent fasting does not mean complete avoidance of foods and drinks. Instead, you markedly reduce your intake of food during certain periods. The benefits of intermittent fasting can be seen as long as you significantly reduce your total caloric intake during those periods.

How Eating Less May Prolong Life

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.

Fried vs Unfried Potatoes

A study of 4400 North American men and women, ages 45 to 79, followed for eight years, showed that those who ate fried potatoes two or more times a week were at increased risk for dying during the study period, compared to those who ate fried potatoes occasionally. Those who ate potatoes that were not fried had no increased risk of death.

Auto-Immune Diseases and Gut Bacteria

Lifestyle changes that affect gut bacteria may help to prevent and treat auto-immune diseases such as rheumatoid arthritis and psoriasis. More than 50 million Americans suffer from autoimmune diseases that look just like a person has an infection because laboratory tests show that a person has an over-active immunity that is trying to kill some germ.

Another Reason Not to Take Calcium Pills

A well-planned study shows that taking calcium pills, both with and without vitamin D, is associated with increased risk for pre-malignant serrated colon polyps.

Why You Feel Sleepy After Eating

If you feel sleepy after eating, particularly after sweets or bakery products, you are normal. Eating sugary foods causes your brain to make large amounts of the neurotransmitter, serotonin, that makes people fall asleep naturally at night.

Are Processed Foods Making Us Fatter?

A small but well-designed study from the National Institutes of Health (NIH) shows how eating processed foods, compared to unprocessed foods, leads you to eat more calories per day and gain more weight.

Coffee Guidelines

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.

WHOLE Grains are Better than Any Flour

When grains are processed into flour or cereals, the primary concern is loss of nutrients. This is explained in report #N178, Why Flour is Like Sugar. However, if you grind your own grains or use products that are made from the whole grain without discarding anything, you get all or most of the nutrients of the original grain. But grains that have been broken apart in any way will be digested more quickly. That's a big disadvantage for diabetics and dieters.

Soluble and Insoluble Fiber

Fiber is the indigestible structural material of plants that is found in all fruits, vegetables, whole grains, beans, nuts and other seeds. Before food can be absorbed from your intestines into your bloodstream, it must be broken down into basic building blocks. Since you lack the intestinal enzymes to break down fiber into its building blocks of basic sugars, you do not absorb fiber in your upper intestines. Fiber passes through your intestines into your colon where soluble and insoluble fiber are treated differently by the bacteria in your colon.

Good News About Nuts and Peanuts

Several recent articles show that eating tree nuts or peanuts with a high-fat or high-sugar meal prevents the expected high rise in blood factors that increase risk for the inflammation that can lead to diabetes, heart attacks or strokes.

Fiber, a True Superfood

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.

Is Honey More Healthful than Sugar?

Some people believe that honey is more healthful than sugar. They tell us that honey is a quicker source of energy and a rich source of minerals, and is less fattening. All of these claims are untrue. As far as your body is concerned, there is no difference between honey and table sugar.

Sweet Potatoes vs White Potatoes

Should you avoid white potatoes and eat sweet potatoes instead? Both white potatoes and sweet potatoes contain a variety of nutrients. Here’s the comparison:

Eat Nuts, Live Longer

People who ate nuts five times a week had a significantly lower rate of heart disease than those who ate less or none. The rate of heart disease decreased by 10 percent for every serving per week of increased intake of nuts.

Sugar-Added Foods Increase Diabetes Risk

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...

Cheese, Yogurt or Milk?

Much controversy still exists over whether dairy products are healthful or harmful. However, the recent literature shows that milk is a high-sugar drink, and accumulating evidence over the last few years shows that fermented dairy products such as cheese and plain yogurt, which humans have made for more than 8000 years, may be far more healthful than milk.

How to Cook Whole Grains

Whole grains are easy to cook on the stovetop, just as you would cook rice or pasta. I always cook one pound (2½ cups) of whole grains at a time, since they keep well -- refrigerated or frozen. Leftovers can be reheated in a microwave or used in salads. I make my own "instant grains" by packaging ½-1 cup portions in baggies and storing them in the freezer. They take a minute or less to thaw in the microwave.

Keto Diets Increase Risk for Fatty Liver

The various ketogenic diets that severely restrict all carbohydrates and replace them mostly with fats are associated with increased risk for non-alcoholic fatty liver disease or NAFLD. NAFLD can lead to diabetes, heart attacks, strokes, liver cancer and other cancers.

Amphetamines Found in Supplements

The U.S. Food and Drug Administration scientists tested 21 "all natural" supplements claiming to help weight loss, increase energy and stabilize mood, and found that nine of them contained manufactured amphetamines (Journal of Pharmaceutical and Biomedical Analysis, November 2013). Manufactured amphetamines are found nowhere in nature and therefore cannot be "natural". It is incredible...

Grass-fed vs Corn-fed Meat

Nobody has presented good evidence that eating meat from grass-fed animals is more healthful than the meat from corn-fed animals. The main health arguments for eating grass-fed meat are its lower fat content and higher content of omega-3 fatty acids.

Why Nuts Won’t Make You Fat

Nuts are a rich source of fat, but many studies have shown that the fat in nuts is absorbed very poorly. This month a study explains why nuts are not fattening.

High Fructose Corn Syrup plus Beekeeping/Honey information

contributed by Lazslo Pentek I am the owner of Hex Apiaries in Arlington, Virginia, where I raise honeybees and harvest honey using no chemical pesticides, or antibiotics. I'm writing to address something you said in your e-zine. It concerns this question and answer: "In last week's ezine, you talked about drinks made with fructose, but you...

Coca Cola Pays to Convince You that Sugared Drinks are Safe

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...

The More Vegetables, The Better

Researchers followed 38,981 adults for 16 years (1999-2014) and found that those who ate the most vegetables and the widest variety of vegetables, particularly dark green vegetables, had the lowest rate of heart attacks and heart disease. Studies show that many of the impressive health benefits from eating vegetables, beans, whole grains and fruits come from the short chain fatty acids produced when bacteria in your colon ferment soluble fiber from plants.
