Dietary Fat Consumption of U.S. General Population and LSAH Participants (LSAHNEWSV13_1_1)

Metabolism and nutrition

Scientific Name: Homo sapiens Species: Human

Nationwide, heart disease is the leading cause of death in both men and women. Many clinical studies have shown a correlation between nutrition and cardiovascular health. Much of this research has been focused on dietary fats and oils, which can promote either good health or disease depending on their quality and quantity. So choosing quality fats and oils should help improve personal cardiovascular disease risk and help decrease national cardiovascular disease rates.

The three main types of fats are called saturated, monounsaturated, and polyunsaturated. Excessive consumption of saturated fats is one of the major risk factors for heart disease. Substituting either monounsaturated or polyunsaturated fats for saturated fats may help lower the blood cholesterol level and has been shown to have a protective effect on the cardiovascular system. This investigation compared the quality and quantity of dietary fat intake of the Longitudinal Study of Astronaut Health (LSAH) participants (astronauts and a group of comparison participants) with the U.S. general population.
