Food Nutrition Basics

Study Notes

Food Nutrition

Macronutrients are the body's primary energy source, including carbohydrates, proteins, and fats. Carbohydrates provide quick energy, proteins are crucial for building and repairing tissues, and fats are important for hormone production and insulation. These are essential for maintaining overall health.
Micronutrients, including vitamins and minerals, are essential for various bodily functions. Vitamins support metabolism, growth, and immunity. Minerals play a role in numerous biological processes, like blood clotting and bone health.
Balanced diets containing a variety of foods from different food groups provide the necessary nutrients in appropriate proportions.
Dietary guidelines advise consuming fruits, vegetables, whole grains, lean proteins, and healthy fats. These guidelines emphasize portion sizes and limit intake of processed foods, sugary drinks, and saturated fats.
Nutrient deficiencies can lead to a range of health problems. For example, iron deficiency can cause anemia, while vitamin D deficiency can weaken bones.
A person's nutritional needs vary based on age, sex, activity level, and health conditions.

Food Hygiene

Food hygiene practices are crucial to prevent foodborne illnesses. These practices ensure the safety and wholesomeness of foods.
Proper food handling procedures should be observed throughout the food production and handling processes.
Washing hands thoroughly with soap and water before and after handling food, as well as between handling different foods is a critical aspect of food safety.
Maintaining a clean environment is essential. This includes clean surfaces, equipment, and utensils. Food preparation surfaces must be sanitized to prevent bacterial contamination and cross-contamination.
Proper cooking temperatures are necessary to kill harmful bacteria. Food should reach the appropriate internal temperature for the proper duration to ensure safety.
Storing food at the proper temperature is critical to prevent bacterial growth. Refrigeration prevents rapid bacterial growth.
Avoiding cross-contamination is essential to limit microbial spread.
Food packaging and processing, from storage to transportation, must adhere to specific hygiene and safety standards.
Avoiding raw food contact is another important element of food hygiene.
Expiry dates and safe storage methods should be followed to prevent food spoilage and illness.
Food handlers must have a clear understanding of food hygiene principles, and regular training is often necessary.
Knowledge of food safety hazards and the appropriate protocols for handling these hazards is essential.
The principles of food safety extend to food storage and handling in the home.
