Some people have food intolerances or allergies that cause negative reactions when consuming certain foods. There are several types of food intolerances including enzyme deficiencies that prevent proper digestion, malabsorption issues that impair nutrient absorption, and allergic reactions from the immune system. Coeliac disease is an autoimmune reaction to gluten that damages the small intestine lining. Managing food intolerances requires identifying the specific intolerance and following dietary guidelines developed by a dietitian to avoid problematic foods.

The document serves as a recipe book covering many food categories.
Hygienic practices in food handling and preparation are important to prevent contamination and food poisoning. Regulations cover manufacturing, packaging, transport, storage, food handler health and hygiene, facility sanitation, waste disposal, food preparation, and retail premises. Personal hygiene practices include washing hands and cleaning nails before preparing food, not coughing or sneezing over food, covering infections and cuts, wearing a clean apron, and avoiding licking fingers or touching food with hands. Food should be purchased from clean shops and stored properly at home according to label instructions, with leftovers consumed within 24 hours. Kitchen hygiene requires regularly cleaning surfaces, utensils, and floors and preventing animal access. Waste should be disposed of
Cell respiration converts oxygen and glucose into energy, water, and carbon dioxide. This energy obtained can be used for mechanical movement, maintaining body temperature, metabolic reactions, and transmitting nerve impulses. An individual's energy intake from food should equal their energy output from basal metabolism and physical activity to maintain energy balance. Basal metabolism is the minimum energy required to sustain life and can be calculated based on factors like age, sex, height, weight, and health. Food energy is measured in kilocalories, with 1 g of carbohydrates providing 4 kcal, 1 g of proteins providing 4 kcal, and 1 g of fats providing 9 kcal.
Carbohydrates, proteins, lipids, water, vitamins, and minerals are the main nutrients. Carbohydrates include sugars, starches, and fiber. They provide energy, aid protein use, and are found in fruits, vegetables, grains, and dairy. Proteins build tissues and aid functions; essential amino acids must come from diet. Lipids provide energy storage and insulation; fats can be saturated or unsaturated. Water regulates functions and temperature; dehydration causes thirst and fatigue. Non-starch polysaccharides aid digestion and prevent disease. Nutrients work together as coenzymes to control metabolic reactions.
Meal planning considers various factors about individuals such as age, health conditions, customs, daily activities, likes/dislikes, and climate that influence nutritional needs and food requirements. Preparation and consumption of food is also impacted by the interests, abilities, resources, and atmosphere of the person cooking and eating. Advances in kitchen technology have led to faster lifestyles with more convenience foods and variety available, making meal planning even more important whether at home, restaurants, schools, hospitals, or hotels. Meal planning involves creating balanced meals that provide all necessary nutrients and considering special diets and definitions of meals like breakfast, lunch, dinner, and terminology used.
The nutritional value of foods is affected by many factors from production to consumption. Practices like heating, soaking, and exposure to air, light can destroy nutrients like vitamins C, B1, B2, and proteins. Steaming, using gravy or stew liquids, and pressure cooking help retain more nutrients. Combining complementary proteins and vitamins as well as food preparation methods like grating and homogenizing can enhance nutrition. Proper storage and minimal cooking also helps maintain vitamin content.
Organic chemistry covers the major macromolecules that make up living things: proteins, carbohydrates, and lipids. These macromolecules are made through polymerization reactions where smaller monomers like amino acids and monosaccharides combine through dehydration synthesis. Carbohydrates include sugars, starches, and cellulose and are made of carbon, hydrogen, and oxygen. Proteins are made of amino acid monomers and have specific shapes important for their functions. Lipids include fats and are made of fatty acids and glycerol. Enzymes are important protein catalysts that allow reactions to proceed in living cells.
The document summarizes the organs, enzymes, and chemical breakdown involved in digestion. The mouth breaks down starch into dextrin and maltose using salivary amylase. The stomach uses hydrochloric acid and pepsin to break polypeptides into peptides. The duodenum contains enzymes from the liver, pancreas, and intestines that further break down peptides, fats, and starches into smaller molecules that can be absorbed by the small intestine. Undigested material then passes to the colon for water absorption before excretion.
This document contains sample exam questions and answers related to animal nutrition from the Cambridge IGCSE Biology past paper. The questions cover topics such as the digestion process, testing for nutrients, labeling the digestive system, and the roles of the liver and pancreas in fat digestion.

After eating a large Thanksgiving dinner, many people feel sleepy due to the high levels of tryptophan in turkey meat. Tryptophan is an amino acid that is converted into serotonin, a chemical that promotes sleep. However, there is little evidence that turkey leads to more sleep than other meals. While people often attribute sleepiness after Thanksgiving dinner to turkey, the meal itself is likely not the only or primary cause of any effects on sleepiness.
