    ‘Everything in moderation’ diet advice may lead to poor metabolic health in US adults

    HOUSTON – (Oct. 30, 2015) – Diet diversity, as defined by less similarity among the foods people eat, may be linked to lower diet quality and worse metabolic health, according to researchers at The University of Texas Health Science Center at Houston (UTHealth) and the Friedman School of Nutrition Science and Policy at Tufts University. The study was published today in PLOS ONE.

    “‘Eat everything in moderation’ has been a long-standing dietary recommendation, but without much empiric supporting evidence in populations. We wanted to characterize new metrics of diet diversity and evaluate their association with metabolic health,” said Marcia C. de Oliveira Otto, Ph.D., first author and assistant professor in the Department of Epidemiology, Human Genetics and Environmental Sciences at UTHealth School of Public Health.

    Using data from 6,814 participants in the Multi-Ethnic Study of Atherosclerosis, a study of whites, blacks, Hispanic-Americans and Chinese-Americans in the United States, the authors measured diet diversity through different measures. These included the total count (number of different foods eaten in a week), evenness (the distribution of calories across different foods consumed), and dissimilarity (the differences in food attributes relevant to metabolic health, such as fiber, sodium or trans-fat content).

    Researchers evaluated how diet diversity was associated with change in waist circumference five years after the beginning of the study and with onset of Type 2 diabetes 10 years later. Waist circumference is an important indicator of central fat and metabolic health.

    When evaluating both food count and evenness, no associations were seen with either increase in waist circumference or incidence of diabetes. In other words, more diversity in the diet was not linked to better outcomes. Participants who had the greatest food dissimilarity actually experienced more central weight gain, with a 120 percent greater increase in waist circumference than participants with the lowest food dissimilarity.

    To compare with the results seen for diet diversity, the researchers also examined how diet quality relates to metabolic health. Diet quality was measured using established scores such as the Dietary Approaches to Stop Hypertension (DASH) score and the Alternative Healthy Eating Index (AHEI) score. At five years, diet quality was not associated with change in waist circumference.

    At ten years, higher diet quality was associated with about a 25 percent lower risk of developing Type 2 diabetes.

    “An unexpected finding was that participants with greater diversity in their diets, as measured by dissimilarity, actually had worse diet quality. They were eating less healthy foods, such as fruits and vegetables, and more unhealthy foods, such as processed meats, desserts and soda,” said Otto. “This may help explain the relationship between greater food dissimilarity and increased waist circumference.”

    Dietary diversity as measured by food count and evenness was also associated with higher intakes of both healthy and unhealthy foods.

    “Americans with the healthiest diets actually eat a relatively small range of healthy foods,” said Dariush Mozaffarian, M.D., Dr.P.H., senior author and dean of the Friedman School of Nutrition Science and Policy at Tufts University in Boston. “These results suggest that in modern diets, eating ‘everything in moderation’ is actually worse than eating a smaller number of healthy foods.”

    Nikhil S. Padhye, Ph.D., from UTHeath School of Nursing, was a coauthor on the study. Funding came from a research supplement grant awarded to Otto by the National Heart, Lung and Blood Institute of the National Institutes of Health, as part of a larger research grant number R01HL085710, whose principal investigator is the senior author Mozaffarian.

    ‘Everything in moderation’ Reminds me of Sid and Noblyhead at the flog. This bloke is their hero.

    Type two diabetic-low carb diet (50 carbs per day) and two 500mg Metformin pills per day. Apart from diagnosis HbA1c almost 12-all HbA1c results none diabetic. For over eight years my diabetes medication has not changed. My weight has remained stable, I have suffered no ill effects from my diet whatsoever. Every blood test has proved, I took the right road to my diabetic salvation. For almost seven years, I have asked medical professionals and naysayers, how do I maintain non diabetic BG levels on two Metformin other than low carb ? The silence has been deafening !

    Gotta love Dariush Mozaffarian, even if he is hard to spell he does Good Work.

    Yes I read a lot of recipes but don't often follow them mainly because now i live alone I can't be bethered to buy things I'm probably only going to use once. I tend to stick to a reliable range of foods that work and somehow I never get bored with. The main changes are seasonal.

    Also I've found that not eating arsenic or cyanide in moderation is a good plan.
