Trends in Intake of Energy and Macronutrients --- United States,
1971--2000
During 1971--2000, a statistically significant increase in average
energy intake occurred (Table). For men, average energy intake
increased from 2,450 kcals to 2,618 kcals (p<0.01), and for women, from
1,542 kcals to 1,877 kcals (p<0.01). For men, the percentage of kcals
from carbohydrate increased between 1971--1974 and 1999--2000, from
42.4% to 49.0% (p<0.01), and for women, from 45.4% to 51.6% (p<0.01)
(Table). The percentage of kcals from total fat decreased from 36.9% to
32.8% (p<0.01) for men and from 36.1% to 32.8% (p<0.01) for women. In
addition, the percentage of kcals from saturated fat decreased from
13.5% to 10.9% (p<0.01) for men and from 13.0% to 11.0% (p<0.01) for
women. A slight decrease was observed in the percentage of kcals from
protein, from 16.5% to 15.5% (p<0.01) for men and from 16.9% to 15.1%
(p<0.01) for women.
The decrease in the percentage of kcals from fat during 1971--1991 is
attributed to an increase in total kcals consumed; absolute fat intake
in grams increased (5). USDA food consumption survey data from
1989--1991 and 1994--1996 indicated that the increased energy intake
was caused primarily by higher carbohydrate intake (6). Data from
NHANES for 1971--2000 indicate similar trends. The increase in energy
intake is attributable primarily to an increase in carbohydrate intake,
with a 62.4-gram increase among women (p<0.01) and a 67.7-gram increase
among men (p<0.01). Total fat intake in grams increased among women by
6.5 g (p<0.01) and decreased among men by 5.3 g (p<0.01).

Carb intake increased, obesity increased, diabetes increased, cvd's
increased.
Better cut them fats, eh?
You guys better tell me again how the only factor is calories and fat.
