Fortunate to contribute to this edition of @AnnualReviews and the timing couldn't be more serendipitous as nutrition is at the forefront of many folks' minds and there is active conversations about what future Dietary Guidelines should look like. In this review, I detail a history of nutritional guidance in the USA, how it evolved over time and the factors that contributed to its evolution. My hope is that the review is both useful to newcomers to the field as well as experts and that it can inform productive conversations about what the future of nutrition guidance should look like. annualreviews.org/content/jo…

New prospective cohort in @AJCNutrition relevant to the seed oil debates: adipose linoleic acid (% total fatty acids; marker of longer term intake) in the Diet Cancer and Health danish cohort is inversely related to all cause morality (21yr follow up). Arachidonic acid levels tended to be associated with increased risk. As expected, high adipose linoleic acid is related to high vegetable oil intake. Linoleic acid levels & vegetable oil intake were not correlated with adipose arachidonic acid levels. Somewhat limited by only a single baseline biopsy but nevertheless supportive of other cohorts using measures of linoleic acid intake (eg RBC linoleic) as well as feeding trials that the simplistic model of high linoleic intake -> arachidonic acid enrichment in membranes -> inflammation/disease is too simplistic. ajcn.nutrition.org/article/S…
