Summary
Dietary fat intake correlates with many nutrients, but not fat concentration. Antioxidants like carotene and ascorbic acid are inversely related to dietary fat concentration, important for cancer research.
Area of Science:
- Nutrition Science
- Dietary Epidemiology
Background:
- Dietary fat intake is linked to chronic diseases like heart disease and cancer.
- Associations may be confounded by other dietary factors.
- Understanding fat intake correlates is crucial for identifying confounders.
Purpose of the Study:
- To describe the correlates of total grams of fat intake.
- To examine the relationship between nutrient intake and dietary fat concentration (% of energy from fat).
Main Methods:
- Cross-sectional study of 863 women and 538 men (ages 50-85).
- Participants randomly selected from two western New York counties.
- Analysis of nutrient intake, including total fat, protein, carbohydrates, fiber, cholesterol, retinol, iron, calcium, carotene, and ascorbic acid.
Main Results:
- Most nutrients correlated with total grams of fat intake.
- Carbohydrates and dietary fiber were not related to fat concentration.
- Alcohol intake negatively associated with fat concentration in men.
- Carotene and ascorbic acid negatively associated with fat concentration.
Conclusions:
- Dietary fat intake correlates with various nutrients, but not necessarily fat concentration.
- Inverse relationship between antioxidants (carotene, ascorbic acid) and fat concentration is significant for cancer research.
- Findings highlight potential confounders in diet-disease relationship studies.
