Micronutrients are commonly referred to as minerals and vitamins. There are many different micronutrients, for example iron, which is an essential mineral helps transport oxygen throughout the body. And since iron is an impirya t part of haemoglobin (which equals roughy 2/3 of the body's iron) which is the stuff inside of red cells which transports oxygen from the lungs to the rest of the body. And if you don't get enough the body can't produce healthy red blood cells and a lack of these leads to an iron deficiency known as anemia. Another micronutrient which is a type of vitamin known as vitamin k which is important as it controls normal blood clotting in the body. Vitamin K also aids in transporting calcium throughout the body, and vitamin K may also help reduce bone loss as weall as bone fractures. A deficiency in this micronutrients can result in inadequate blood clotting, an increased amount of bleeding as well as osteopenia. Another type of micronutrient is magnesium which is important as it helps the heart maintain a normal rhythm as all as helping the body convert glucose into energy.

There is also macronutrients which are made refer to things such as carbohydrates, proteins and lipids. One example of a carbohydrate is starch, which is broken down by digestion into constituent sugar molecules, which in turn supply energy to the tissues of the body. If not enough starch is eaten a condition known as hypoglycemia, otherwise known as blood sugar occurs,which can negatively impact health. Another micronutrient example is a lipid, a type of polyunsaturated fat called
omega-3 fatty acids which help the body by preventing irregular heartbeat patterns, reducing the buildup of fatty plaques inside of stern walls, decreased amounts of blood clotting, as well as increasing the amount of HDL, otherwise known as good cholesterol. Another example is dietary fibre which is another macromolecule which is important in maintaining a healthy digestive system i.e. regular bowel movements, research has also shown that a diet high in fibre is associated with a reduced risk of stroke, type 2 diabetes, heart disease as well as bowel cancer, it also helps maintain blood sugar levels and cholesterol levels, and keep them in a normal range.
