Vitamin K and vitamin D are not made in our body it come from the balance diet (Norris, and et. al., 2020). FibreFibres are responsible for the regulation of the sugar. It also assists body to keep appetite. It assists in the digestion of food in human body. Soluble decrease the bad cholesterol level in human body.

MineralMinerals make bone, muscles, brain and heart workingappropriately.Mineralsarealso responsible for formation of hormones and enzymes. Minerals play a many different role involving muscle contraction and relaxation. Choose three from the following list, describe what the deficiency is, and the effects each has on the body: (AC 2.2)Vitamin D deficiency:Vitamin D does not form in our body. It is obtain from the external food and sunlight. Vitamin deficiency can cause decrease of bone density and results broken bone and osteoporosis. It also play an important role in immune health. It 3
may assist to prevent cancer diseases. It deficiency can cause depression, bone loss, type 2 diabetes, heart disease, and multiple sclerosis.Iron deficiency:it is a condition in which too little amount of iron found in our body. Most common cause of this deficiency ischronic, slow blood loss in the body due to the Hiatal Hernia, Peptic Ulcer, Colorectal Cancer, Colon Polyp and so on. Iron deficiency can results anaemia. Iron cell assist to produce red blood cell in our body so, deficiency of iron can cause decrement in number of Red blood cell. Red blood cell carry oxygen but in the deficiency of iron number of Red blood cell decrease so number of Oxygen taken also decreases (Sato, and et. al., 2018). Vitamin C deficiency:Vitamin C deficiency occur due to the poor vitamin c rich diet, anorexia, smoking, mental illness, dialysis and alcoholism. It deficiency can cause scurvy, inflammation of gums, fatigue, small purple or red spots on theskin, poor wound healing and so on (Singh, and et. al., 2018).
