It’s worth looking at how protein, carbs, dietary fat and caloric intake have changed in the U.S. from 1971–2000.
We eat more calories. For men, up from 2,450 kcals/d to 2,618 kcals; for women, up from 1,542 kcals to 1,877 kcals/d.
Carbs increased 1971–1974 (Atkins 1) and 1999–2000 (Atkins 2), for men from 42.4% to 49.0%, and women, from 45.4% to 51.6% .
Fat went down 36.9% to 32.8% for men and from 36.1% to 32.8% for women. On average, daily.
Protein went down a little, from 16.5% to 15.5% for men and from 16.9% to 15.1% for women.
In 1970, 12% of men and 17% of women were obese. In 2000, this was 31% and 34%.
In 1996, according to the CDC, weight gain came from eating more often away from home; eating more salty snacks and drinking more soft drinks; and eating bigger portions.
It is probably still true, 10 years later.
Last week’s too-often misreported breast cancer whi 2006 jama study about dietary fat, breast cancer and heart disease didn’t help clear things up…but as always, the details are what makes the story interesting.
