- Nutrition is the scientific study of nutrients and their usage in the body.
Antioxidants and Phytochemicals
- Antioxidants protect other compounds from damage or destruction.
- Phytochemicals are non-nutrient compounds produced by plants, such as organosulfides found in garlic and cruciferous vegetables.
Essential Nutrients and Risk Factors
- An essential nutrient must be obtained from food.
- A risk factor is a personal characteristic that increases the likelihood of developing a disease.
Macronutrients and Nutrient Density
- Carbohydrates, fats, and proteins are categorized as macronutrients.
- Nutrient density refers to the ratio of nutrition to calories in food.

- The Federal Trade Commission investigates misleading health claims.
Study Examples
- The placebo effect occurs when participants believe a treatment improves their condition despite not receiving it.
- Anecdotes, such as personal claims of strength gain from supplements, are not scientifically valid evidence.
Obesity Research and MyPlate
- Epidemiological studies explore factors affecting obesity in populations.
- According to the MyPlate plan, cheese is not categorized with protein.
Nutrient Recommendations
- The Tolerable Upper Limit indicates the maximum daily intake unlikely to harm most individuals.
- The Recommended Dietary Allowance (RDA) for vitamin C meets the needs of approximately 98% of the population.
- The Acceptable Macronutrient Distribution Range (AMDR) suggests that carbohydrates should comprise 45 to 65% of total energy intake.
