Update, 7 September 2017: No, carbohydrates are not detrimental. People who eat vegetables, fruit and beans (all high-carb) live longer than people who don’t. That’s what the PURE study found. See my follow-up post: PURE Study Couldn’t Tease Apart Affects Of Poverty And Diet (Dr. Katz: PURE Diet Nonsense).
High carbohydrate intake was associated with higher risk of total mortality, whereas total fat and individual types of fat were related to lower total mortality. Total fat and types of fat were not associated with cardiovascular disease, myocardial infarction, or cardiovascular disease mortality, whereas saturated fat had an inverse association with stroke. Global dietary guidelines should be reconsidered in light of these findings.
