David Katz, M.D.

The nation's official position for the next five years on diet for health is on the line, imperiled by bullies. I am speaking out simply because we don't know how many others, encountering the same forces, have decided doing so is not worth the abuse. I am speaking out because: it is.

David Katz, M.D. | Posted 10.11.2016 | Healthy Living
David Katz, M.D.

The controversy and clamor attached to the report of the 2015 Dietary Guidelines Advisory Committee would seem to suggest that something that radical had been proposed. But that's not quite the case.

Milking Dietary Discord: Who Holds the Bucket?

David Katz, M.D. | Posted 10.07.2016 | Healthy Living
David Katz, M.D.

David Katz, M.D.

There may well be duties in these data for university officials. But there are duties in them for parents, too. The victims are, inescapably, our daughters. The report is shockingly silent on the fact that the perpetrators are, inevitably, our sons.
