Open Future HealthDietary Guidelines Advisory Committee 2015 Report

WWW LinkThe 2015 DGAC Scientific Report hints at further need for scientific research, but essentially reconfirms previous recommendations. WWW LinkDietary Guidelines for Americans is the version of the report intended for the public.

WWW LinkThis work is further refined into a usable eating guide called My Plate. However by now the strong criticism of the recommendations is being felt and there are some minor concessions.

Good News: There is a recommendation to avoid sugary drinks and the use of sugar substitutes. The recommendation to avoid eating dietary cholesterol has been removed. They concede that the Mediterranean Diet might have some advantages. And they even recommend a vegetarian diet.

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

Healthy Diet

A healthy dietary pattern is higher in vegetables, fruits, whole grains, low or non-fat dairy, seafood, legumes, and nuts; moderate in alcohol (among adults); lower in red and processed meats; and low in sugar-sweetened foods and drinks and refined grains.

Strong evidence shows that it is not necessary to eliminate food groups, or conform to a single dietary pattern, to achieve healthy dietary patterns. Rather, individuals can combine foods in a variety of flexible ways to achieve healthy dietary patterns, and these strategies should be tailored to meet the individual's health needs, dietary preferences and cultural traditions.

The Banting Diet suggests Local Filethat if you have damaged your metabolism, and the evidence is that most of us have, eliminating all high-carbohydrate foods from your diet, is beneficial. The more damaged your system is, (How carbohydrate intolerant you've become.) the more restrictive your diet needs to be.
