Nutrition Basics and Food Groups

Study Notes

Nutritional Needs and Components

Food provides the body with energy, nutrients, and substances for growth, maintenance, and tissue repair.
Macronutrients (carbohydrates, proteins, and fats) are needed in large amounts.
Carbohydrates, the primary energy source, are composed of sugars, starches, and fibers.
Proteins build and repair tissues, produce hormones and enzymes, and contain amino acids.
Fats are crucial for hormone production, insulation, and cell membrane structure. Different types of fats have varying health impacts.

Food Groups and Varieties

MyPlate guidelines encourage a balanced diet from various food groups.
Fruits and vegetables provide vitamins, minerals, and fiber for bodily functions.
Grains furnish complex carbohydrates and fiber, promoting sustained energy.
Protein sources include meats, poultry, fish, beans, lentils, and nuts.
Dairy (or alternatives) offer calcium and vitamin D for bone health.

Food Safety and Preparation

Safe food handling and storage prevent foodborne illnesses.
Bacteria and pathogens contaminate food, causing infections.
Safe food practices involve proper temperatures for storage and cooking, handwashing, and avoiding cross-contamination.
Cooking food to appropriate internal temperatures kills harmful bacteria.
Clean kitchen sanitation prevents foodborne illnesses.

Food Allergies and Intolerances

Food allergies are immune system reactions to food proteins.
Common allergens include peanuts, tree nuts, milk, eggs, soy, wheat, fish, and shellfish.
Allergy symptoms range from mild skin reactions to severe anaphylaxis.
Food intolerances do not involve the immune system, but can cause digestive issues or discomfort.
Lactose intolerance is a common example, involving reactions to dairy components.

Food and Health

A balanced diet supports overall health and reduces chronic disease risk.
Proper nutrition maintains a healthy weight and reduces risks of heart disease, type 2 diabetes, and certain cancers.
Dietary recommendations emphasize whole foods, limit processed foods, and control portion sizes.
Food choices affect nutrient balance, energy levels, mood, and overall health.

Food and Culture

Food traditions and preferences vary culturally and geographically.
Cultural traditions shape dietary habits, food choices, and the importance of specific foods.
Specific ingredients and cooking methods are emphasized in some cultures; food is often central to social gatherings.

Food Production and Sustainability

Food production significantly impacts the environment.
Sustainable food practices minimize environmental damage, boost biodiversity, and improve resource use.
Sustainable agriculture employs practices like reduced pesticide use and crop rotation to lessen the environmental footprint of food production.
Consumer choices influence food production practices and promote sustainability.
