Area of Science:

  • Public Health Nutrition
  • Dietary Guidelines
  • Cancer Prevention

Background:

  • National health objectives for 2000 recommended reduced dietary fat and alcohol, and increased fruit, vegetable, and grain intake to lower cancer risk.
  • This study assesses dietary trends in relation to these public health goals.

Purpose of the Study:

  • To evaluate trends in the consumption of key dietary components (fat, alcohol, fruits, vegetables, grains).
  • To determine if these trends align with national health objectives for cancer risk reduction.

Main Methods:

  • Review of national food supply data.
  • Analysis of national food consumption survey data for trend monitoring.

Main Results:

  • Americans show modest but significant dietary improvements, increasing intake of fruits, vegetables, and grains.
  • Decreased consumption of dietary fat and alcohol observed.
  • Dietary trends correlate with improved mortality rates for diet-associated cancers (colon/rectum, prostate, breast).

Conclusions:

  • Average intake of fruits, vegetables, and grains has increased, approaching national objectives.
  • Further dietary improvements are possible within food groups; focus needed on children's diets.
  • Continued monitoring of dietary habits in children and specific subgroups is recommended.
