Food Nutrition

Macronutrients are essential components of a balanced diet, providing energy and building blocks for growth and repair. These include carbohydrates, proteins, and fats.
Carbohydrates are the primary source of energy for the body. Simple sugars provide quick energy, while complex carbohydrates (e.g., starches) provide sustained energy.
Proteins are critical for building and repairing tissues, and also play a role in various bodily functions. They are composed of amino acids, some of which the body cannot produce (essential amino acids) and need to be obtained from foods.
Fats are crucial for hormone production, vitamin absorption, and insulation. Unsaturated fats are generally healthier than saturated fats. Trans fats are considered the least healthy type of fat.
Micronutrients, including vitamins and minerals, are needed in smaller amounts but are essential for many bodily functions, such as metabolism and immune function. Vitamins are organic compounds, and minerals are inorganic.
Water is essential for various bodily functions, such as temperature regulation, nutrient transport, and waste removal. It comprises a significant portion of human body weight.

Food Hygiene

Food safety involves practices that prevent foodborne illnesses.
Safe food handling starts at the farm or source of the food and continues through preparation and cooking methods.
Cross-contamination is a major risk factor in foodborne illness. This happens when pathogens are transferred from one food item to another.
Proper temperature control is essential for food safety. Foods should be stored and cooked at appropriate temperatures to kill or inhibit the growth of harmful bacteria and other microorganisms.
Foodborne illnesses can be caused by various microorganisms, including bacteria (e.g., Salmonella, E. coli), viruses (e.g., norovirus), and parasites.
Personal hygiene is crucial for food safety. Food handlers should wash their hands thoroughly and frequently, wear appropriate protective gear, avoid handling food when ill, and maintain a clean workspace.
Cleaning and sanitizing food preparation areas and utensils regularly prevents the buildup of harmful bacteria and contaminants.
Proper food storage is essential to prevent bacterial growth. Foods should be stored at appropriate temperatures and for appropriate periods, depending on their type and the conditions of storage.
Food preservation methods, such as refrigeration, freezing, and canning, help extend shelf life and maintain food safety.
Food labeling is important for consumers to know what food products contain. This is particularly important to identify allergies and sensitivities.
