Diet and Nutrition Basics

Diet refers to the total food and beverages consumed by an individual.
Nutrients are substances utilized by the body for tissue growth, maintenance, and repair.

Macronutrients and Dietary Components

Starch is identified as a macronutrient crucial for energy provision.
Resistant starch is the portion of starch that escapes digestion; legumes are high in resistant starch content.
Dietary fiber is essential for digestive health, while starch does not fall under its classification.

DNA and Health

DNA adducts represent chemical modifications that can occur in DNA, indicating potential health risks.
Microscopic analysis shows that samples from individuals on a healthy diet have significantly fewer DNA adducts compared to those on less healthy diets.

Essential Nutrients

Essential amino acids cannot be synthesized by the body and must be ingested through diet.
Vitamins are organic nutrients required in minute amounts for various biological functions that promote health and well-being.
