1. Food is any substance consumed to provide nutritional support for an organism. Food is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals.
2. A food is something that provides nutrients. Nutrients are substances that provide: energy for activity, growth, and all functions of the body such as breathing, digesting food, and keeping warm; materials for the growth and repair of the body, and for keeping the immune system healthy.
3. Nutrients are molecules in food that all organisms need to make energy, grow, develop, and reproduce. There are two major types of nutrients that we need to supply our bodies with energy, macronutrients and micronutrients. Macronutrients are carbohydrates, protein, and fat. Micronutrients are vitamins and minerals.
4. A food ingredient is any substance that is added to a food to achieve a desired effect. The term “food ingredient” includes food additives, which are substances added to foods for specific technical and/or functional purposes during processing, storage or packaging.
5. Protein is an important part of a healthy diet. Proteins are made up of chemical 'building blocks' called amino acids. Your body uses amino acids to build and repair muscles and bones and to make hormones and enzymes. They can also be used as an energy source.
Most animal sources of protein, such as meat, poultry, fish, eggs, and dairy, deliver all the amino acids your body needs, while plant-based protein sources such as grains, beans, vegetables, and nuts often lack one or more of the essential amino acids.
6. Vitamins. Vitamins are a group of substances that are needed for normal cell function, growth, and development. There are 13 essential vitamins. This means that these vitamins are required for the body to work properly. Some vitamins are:
Vitamin A.
Vitamin C.
Vitamin D.
Vitamin E.
Vitamin K.
Vitamin B1 (thiamine)
Vitamin B2 (riboflavin)
Vitamin B3 (niacin)
7. The energy components of food include: carbohydrates (sugars and starches) proteins. lipids (fats).
The non-energy components include:
vitamins.
minerals.
dietary fibre.
water.
8. Test for Carbohydrates:
Molisch’s test – Given sample food + Molisch’s reagent → Purple or violet ring confirms the presence of carbohydrate.
Fehling’s test – Given sample food + Fehling’s reagent → Red precipitate confirms the presence of carbohydrates
Benedict’s test – Given sample food + Benedict’s reagent → Red precipitate confirms the presence of carbohydrates.
Tollen’s test – Given sample food + Tollen’s reagent → Silver mirror confirms the presence of carbohydrates.
Iodine test – Given sample food + Iodine solution → Blue colour solution confirms the presence of starch.
9. A balanced diet is a diet that contains differing kinds of foods in certain quantities and proportions so that the requirement for calories, proteins, minerals, vitamins and alternative nutrients is adequate and a small provision is reserved for additional nutrients to endure the short length of leanness.
10. The main sources of our food are Plants and Animals. Plants are the sources of food ingredients like grains, cereals, vegetables and fruits. Animals are the another source which provide us with milk, meat products and eggs. Cows, goats and buffaloes are some common animals which give us milk.
