Open Future HealthDietary Guidelines Advisory Committee

The original recommendations of the DGAC were made in 1977.

Good News: Every five years, they revise their recommendations. This text is about what you know about, the old 2010 Report. In the new 2015 report, some of these recommendations were changed.

Dietary Guidelines Advisory Committee Recommendations

2010 Guidelines

My comments are in this style. This is a short summary of key ideas.

Despite the new science I write about in this site, the DGAC continues to make STRONG recommendations largely confirming the original dietary goals. In many places, there is acknowledgement that the new science exists, but the committee stands firm. For instance; "Healthy diets are high in carbohydrates" (Not always true.).

The U.S. Department of Health and Human Services (HHS) and the U.S. Department of Agriculture (USDA) jointly publish the Dietary Guidelines for Americans. I suspect, that the reluctance to change guidelines when the evidence that they cause obesity is so strong, is political. The U.S. Department of Agriculture (USDA)has a primary responsibility to support American farmers.

The fact that the American public continues to get fatter and fatter is acknowledged, even large numbers of children. But constantly the DGAC says that the failure of the public to follow the guidelines is the problem. They blame the public. (Which is unfair. Over 30 years the American diet has moved quite a lot, always towards the guidelines. Diets have much fewer saturated fats. People eat more chicken and less red meat. The consumption of whole grains and carbohydrates have increased tenfold. Remember the DGAC said. "Healthy diets are high in carbohydrates".).

The DGAC often affirm that losing weight is a simple matter; eat fewer calories than you burn in your daily life. Calories in v calories out, it's simple mathematics. For instance: "There is strong and consistent evidence that when calorie intake is controlled, the macro-nutriment proportion of the diet is not related to losing weight." (Not true)

They recommend a "shift of food intake patterns to a more plant-based diet that emphasizes vegetables, cooked dry beans and peas, fruits, whole grains, nuts and seeds." (That's an option not necessarily a healthy option. For instance Local FileThe Women's Health Initiative, found there were NO health advantages in the low-fat high-carbohydrate diet for older women.)

The DGAC speaks strongly against low-carbohydrate high-fat diets, while admitting that they are effective in reducing weight. So the committee would see nutritional ketosis as "less safe," and "can't be maintained in the long term," and "will cause a dramatic increase in triglycerides," and "the increase in dietary saturated fat will increase the risk of heart disease".

The key factor in ketogenic diets is to reduce carbohydrate intake. Local FileThe new science claims that Nutritional Ketosis is the preferred treatment for Local Filetype 2 diabetes, is highly protective against Local Filecardio-vascular disease, and significantly reduces dental caries. In contrast the DGAC strongly state: "There are no detrimental effects of carbohydrates as a source of calories on these or other health outcomes."

2015 DGAC Report

WWW LinkThe full report is 500 pages long. These two statements, on sugary drinks and cholesterol are new:

"Added sugars should be reduced in the diet and not replaced with low-calorie sweeteners, but rather with healthy options, such as water in place of sugar-sweetened beverages."

"Individuals have many potential options for reducing the intake of added sugars. Strategies include choosing beverages with no added sugars, such as water, in place of sugar-sweetened beverages, reducing portions of sugar-sweetened beverages, drinking these beverages less often, and selecting beverages low in added sugars."

"Previously, the Dietary Guidelines for Americans recommended that cholesterol intake be limited to no more than 300 mg/day. The 2015 DGAC will not bring forward this recommendation because available evidence shows no appreciable relationship between consumption of dietary cholesterol and serum cholesterol … [because] Cholesterol is not a nutrient of concern for over-consumption."
