USDA:n kommenttipyynnössä mainitaan tyydyttynyt rasva ja sokeri (erityisesti juomissa) sekä vanhusten ravitsemus.

With this announcement, USDA and HHS implied there are other topics where recommendations could be out of sync with current nutrition science. Saturated fats have clearly been the subject of much rethinking in recent years, and the DGA’s three “Dietary Patterns,” have been criticized for being nutritionally insufficient, in addition to remaining a one-size-fits-all diet.
USDA and HHS are also seeking public feedback on nutrition for infants, proper nutrition for those over 65, and the role of beverages and sugars in the diet for adults.
Tärkeimmät asiat, joista USDA saa kommentteja ainakin Nutrition Coalitionin asiantuntijoilta:

Here are the two topics that rise to the top for The Nutrition Coalition:
Saturated fats: the science has clearly evolved. See our primer on the latest science here.
The DGA should offer a true range of diets, including one for people with metabolic conditions, such as obesity, type 2 diabetes, and heart disease. We suggest an additional, low-carbohydrate “Dietary Pattern” for these populations. Carbohydrate restriction is supported by a sizeable body of rigorous clinical trial evidence, showing it to be both safe and effective for combatting these diseases. The diet is clearly “evidence-based,” as demonstrated in a recent letter signed by nearly 34,000 people. The text of this letter provides a summary of the evidence.
Also important are:
There is scant scientific evidence on diets for infants 0-2, post weaning, or children generally. Past recommendations have extrapolated from data on adults, based on the assumption that the same diet would be appropriate for children, but the advice given to middle-aged men and women, for the avoidance of heart disease, obesity, etc., may very well not appropriate for growing children, who have different nutritional needs. Based on the principle of “first, do no harm,” The Nutrition Coalition recommends that the DGA not issue recommendations for these populations, other than for nutritional sufficiency.
There is a lack of rigorous clinical trial data showing health benefits of a vegan/vegetarian diet. A review prepared by the USDA Nutrition Evidence Library (NEL) for the 2015 Dietary Guidelines report concluded that the evidence for this diet’s disease fighting powers is only “limited,” which is the lowest rank for available data. Moreover, although the NEL conducted eight reviews on fruits and vegetables, none found strong (grade 1) evidence to support the assertion that these foods can provide health benefits.
