Restricting Calories for Just Five Days a Month May Prolong Life

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...

Calcium Pills Do Not Prevent Fractures

In light of the overwhelming evidence that extra dietary calcium does not prevent fractures, it is very puzzling that many medical and public health organizations still recommend extra calcium

Dietary Changes Lecture Slides

This video contains slides from Dr. Gabe Mirkin's 2018 lecture on Dietary Changes to Help You Lose Weight and Prevent Heart Attacks, Diabetes and Cancers    

Gluten-Free Diets Can Harm

Two studies in prestigious medical journals show that gluten-free diets can cause nutritional deficiencies in all age groups (Clinical Nutrition, published online May 7, 2016) and interfere with growth and development in children.

Do Vegetarians Live Longer?

Three recent large studies provide more support for a primarily plant-based diet. Two of the studies compared dietary protein from plants and animals and the third one compared dietary fats from plant or animal sources.

Animal Products Linked to Increased Heart Attack Risk

For more than 60 years we have heard that saturated fat and cholesterol may be the driving forces behind the high rate of heart attacks in North America. A new study shows strong statistical links between eating a lot of high-cholesterol animal products -- eggs, meat, poultry, and dairy -- and risk for heart attacks.

Two Clues to the Obesity Epidemic

Certain bacteria in your colon may turn dietary fat into body fat to make you fat, and antibiotics may alter gut bacteria to a larger proportion of the types that make you fat

Obesity Epidemic Now Worldwide

The rate of obesity worldwide has doubled in 73 countries since 1980. Today 30 percent of North Americans and 10 percent of the world's population are obese, an estimated 604 million obese adults and 108 million obese children. A recent article suggests that this world-wide increase in obesity is driven by the huge companies that make processed foods, sugared drinks and refined carbohydrates, and the extensive advertising they do for their products.

Long Fasts May Increase Diabetes Risk

At the European Society of Endocrinology meeting in Barcelona (May 20, 2018), a study was presented that found that three months of alternating 24-hours of fasting on one day and eating unrestricted food on the next day caused rats to eat less total food and lose total body fat, but the rats developed signs of becoming diabetic.

Should You Eat Breakfast?

Skipping breakfast will not help you lose weight or cause you to gain weight. This month's issue of The American Journal of Clinical Nutrition contains three studies on breakfast. One study shows that whether you eat breakfast or not doesn't affect your weight at all (American Journal of Clinical Nutrition, 2014;100:507-13). Three hundred volunteers...

New Dietary Guidelines

the Dietary Guidelines issued in January 2016 by the U.S. Department of Agriculture and the Department of Health and Human Services recommend * restricting sugar, salt, saturated fat, and trans fats, and eating more fruits, vegetables, whole grains, lean meat, and low-fat foods. The recommendation to eat lean meat has caused the most criticism by scientists.

How Red Meat May Increase Risk for Cancer

This week, Dr. Ajit Varki of the University of California at San Diego showed for the first time that feeding genetically-engineered mice a sugar called Neu5Gc, found in red meat, caused them to produce anti-Neu5Gc antibodies that caused spontaneous cancers (Proceedings of the National Academy of Sciences, published online Dec. 29, 2014). Several previous studies...

Will Gluten-Free Make You Feel Better?

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.

Phytochemicals

Phytochemicals are substances found in plants that have been identified by researchers as beneficial to humans. We have identified only a few of the thousands of phytochemicals, and we do not fully understand how they work. Here are a few that have been linked to prevention of specific diseases. Phytochemicals That Help to Prevent Cancer: peppers contain...

Chewing Raises Blood Sugar Response to Food

Chewing rice 30 times before swallowing it raised blood sugar much higher than chewing rice 15 times.

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-

Added Sugars: Labels Can Deceive

Sugar added to food affects you differently than sugars in whole fruits and vegetables. Clinical trials in humans and population studies show that sugar added to foods increases risk for diabetes and heart attacks, while sugar in whole fruits does not.

Big Sugar Uses Big Tobacco Tactics

The U.S. Food and Drug Administration proposes that, to reduce heart disease, all foods with added sugar have labels listing the amounts of added sugar and recommended restriction levels. The proposed rule sets the intake of added sugar for packaged food and beverages at no more than 200 calories a day, or 10 percent of the 2,000-calorie diet generally used for nutrition guidance.

Big Sugar Does It Again

n eye-opening new report shows that between 2011 and 2015, Coca-Cola gave more than $6 million a year and PepsiCo gave more than $3 million a year to 96 national health organizations. At the same time, they gave more than $1 million a year to the American Beverage Association, their industry lobbying group, to influence legislation to favor the soda industry and against the interests of public health.

Weight Gain with Sugar Plus Meat

If you take a sugared drink while eating meat, the animal protein reduces your ability to burn off the calories from sugar by more than a third. In this elegant new study, 27 healthy-weight adults spent two full days in a sealed "metabolic room" that measured how many calories their bodies burned each minute by tracking their intake of oxygen and outflow of carbon dioxide and measuring calories lost in their urine.

High Dose Vitamins Associated with Increased Risk for Lung Cancer

Vitamins B6 and B12 have been promoted by the supplement industry for many years, touting benefits such as increased energy and higher metabolism. A new study suggests that these high-dose vitamin supplements are associated with increased risk for lung cancer in men, particularly in smokers.

Dangers of Processed Foods

Many processed foods are full of sugar and salt that raise blood pressure, increasing risk for heart attacks, strokes, and premature death. Most dietary salt does not come from the salt shaker and most dietary sugar does not come from the sugar bowl.

More Reasons to Eat Plants

Two strong studies show that 1) giving people with heart disease a diet that is high in fruits and vegetables and low in red meat is more effective than taking statin drugs in preventing heart attack deaths, and 2) eating red meat regularly increases risk for death from a heart attack.

Major Alcohol Study Cancelled for Conflict of Interest

The National Institutes of Health cancelled and withdrew funds for a prospective study on how drinking alcohol affects heart attack risk because it was to be largely funded by the alcohol industry itself, and for "concerns about the study design that cast doubt on its ultimate credibility."

Why Excess Weight Kills

Of the many factors causing more than 40 percent of Americans to die of heart attacks and 35 percent to become diabetic, the strongest are eating too much and exercising too little. Being Fat Makes You Even Fatter Having diabetes is one of the strongest risk factors for heart attacks and premature death. Before insulin can...

Dietary Recommendations Opposed by Industry

Corporate interests from the meat and sugar industries are actively disputing dietary recommendations that could help prolong the duration and enhance the quality of the lives of many North Americans.

Take Vitamin D Pills Only If You Have a Deficiency

Doses of vitamin D greater than 4,000 IUs increase risk for kidney stones, calcification of blood vessels and even the very cardiovascular disease you were seeking to prevent. The dose of vitamin D recommended by the National Academy of Sciences is 600 international units daily for those up to 70 years of age , and 800 IU for those over 71.

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...

Does stress increase your need for vitamins?

Several years ago a major drug company claimed that its vitamin pills helped to relieve stress from the "complications of everyday life" and gave their products names such as "StressTabs." The New York Attorney General forced them to stop their deceptive advertising, but many people still remember and believe this claim.

Drinking Water Does Not Cause Weight Loss

Drinking extra water with meals will not reduce the amount of food that you eat. If you drink several glasses of water with your meals, the extra water will distend your stomach and make you feel full for a minute or two, but the water leaves your stomach so quickly that you feel hungry again.
