Mariam Haider Micronutrients Vitamins Written Task Design Brief; Foods are not ‘pure’ substances. Although referred to as protein foods‚ or carbohydrate foods‚ this only recognized the food to be high in a particular nutrient. In fact‚ foods are mixtures of different nutrients and other chemical substances such as toxins‚ pigments and additives. Protein‚ carbohydrates and fat are regarded as macronutrients due to the size of their molecules. These nutrients are needed in large quantities

VITAMINS AND MINERALS Vitamins and minerals make people’s bodies work properly. Although you get vitamins and minerals from the foods you eat every day‚ some foods have more vitamins and minerals than others. Vitamins fall into two categories: fat soluble and water soluble. The fat-soluble vitamins — A‚ D‚ E‚ and K — dissolve in fat and can be stored in your body. The water-soluble vitamins — C and the B-complex vitamins (such as vitamins B6‚ B12‚ niacin‚ riboflavin‚ and folate) — need to dissolve

Investigating the Effect of Caffeine on the Heart Rate of Daphnia Daphnia are extremely small aquatic invertebrates. They are transparent‚ so you are able to see their internal organs; this means it is easy to monitor their heart rate by observing them through a microscope [1]. Physiological results from caffeine consumption include the stimulation of heart rate‚ blood pressure‚ metabolism‚ body temperature and alertness. [2] In this practical investigation the aim was to determine whether the hypothesis

The experiment users an new and old lemon‚ orange and blackcurrant juice‚ each with varying amounts of vitamin C content. Each experiment has independent and dependent variables. The solutions of soft drinks contain different levels of vitamin C (with old and new varieties) will be the independent variables in the experiment as the vitamin C content is unknown. The dependent

Investigating the vitamin C content of fruit juices Vitamin C (ascorbic acid) is a water-soluble nutrient which is found in certain foods. It acts as an antioxidant (inhibits oxidation) in the body‚ helping to protect cells from the damage caused by free radicals. The body requires vitamin C in order to make collagen‚ a protein essential to help wounds heal. Vitamin C also improves the absorption of iron from plant-based foods and helps the immune system work properly to protect the body from disease

Vitamins‚ Nutrients‚ and Minerals Vitamins‚ nutrients‚ and minerals are all important substances that are required to lead a happy‚ healthy life. Firstly‚ vitamins are an organic compound required by the body in small amounts of metabolism‚ to protect health‚ and for proper growth of children. Vitamins also assist in the formation of hormones‚ blood cells‚ nervous systems chemicals‚ and genetic material. There are 13 well-identified vitamins. Some examples of the 13 well-identified
