Study Notes
Definition of Food and Nutrition
- Food is defined as substances consumed by people and animals that provide nutrients to sustain life.
- Good nutrition is important for health as it helps in preventing chronic diseases.
Factors Influencing Food Choices
- Social interaction is one of the factors that influence our food choices.
Nutrients and Energy
- There are six major classes of nutrients.
- Energy balance refers to the balance between energy intake and expenditure in the body.
- Energy values of food are determined by analyzing their nutrient composition.
- Energy expenditure is contributed by basal metabolic rate, physical activity, digestion and absorption, and thermic effect of food.
Energy Intake and Body Weight
- Consuming more calories than the body needs for energy expenditure leads to weight gain.
Measuring Obesity and Body Composition
- Obesity and body composition can be measured using body mass index (BMI), waist circumference, and skinfold caliper measurements.
Misinformation in Nutrition
- Misinformation in nutrition can lead to poor health outcomes, be misleading and inaccurate, and create confusion among the general public.
Identifying Reliable Nutrition Information
- Reliable nutrition information can be identified by checking the credibility of sources, looking for peer-reviewed research, and considering the context of the information.
