Consequence of enough people unwilling to distinguish inductive intuition from superstition is falling for formal-sounding folk wisdom. We ate fatty meats, nuts, and dairy just fine for thousands of years, but that doesn't satisfy our dutiful impulse to feel in control of their circumstances. My soy-minded father was also concerned with excess servings of protein (better than forced veganism), or jogging ruining fast-twitch muscles (which would have effected me if I wasn't already blessed with substandard cardiovascular organs. He was not a bodybuilder or powerlifter). Thanks, leaded gasoline.
