Folate Everyone needs folate vitamin B9 to make new cells every day. Folate is essential in the earliest days of fetal growth for healthy development of the brain and spine Folic acid is another form of vitamin B9.
Women of reproductive age need micrograms of folic acid every day Ensuring sufficient levels of folate in women prior to conception can reduce neural tube defects such as spina bifida and anencephaly Providing folic acid supplements to women years and fortifying foods such as wheat flour with folic acid reduces the incidence of neural tube defects and neonatal deaths Folate is especially important before and during pregnancy.

For example, vitamin A is essential for healthy mucous membranes, skin and eyes. B vitamins are involved in the production of energy and in the functioning of the nervous system.
Trace elements chromium, iron, iodine, copper, zinc are present in very small quantities in the body. The difference between a trace element and a mineral primarily sodium, potassium, magnesium, calcium, phosphorus and sulphur is that minerals are present in larger quantities.
All are responsible for numerous vital functions. These compounds give fruit and vegetables their colour and have anti-oxidant properties. Countless studies have shown that a diet rich in fruit and vegetables reduces the risk of cancer and cardiovascular disease primarily by preventing the formation of atheromatous plaques.
By combatting free radicals and inflammation, polyphenols, flavonoids and carotenoids protect the cells from premature ageing. The body continually produces free radicals, which can be thought of as a particularly aggressive waste product, and which, in very large amounts, cause chain reactions which damage tissues and the organs, and can even modify certain genes.
A second line of defence is provided by anti-oxidants obtained from the diet.

They play critical roles in disease prevention. A few micronutrients are vitamins A, C, and D and the minerals iron, potassium, and calcium. This article discusses micronutrients in food, the need for micronutrients, symptoms of micronutrient deficiency, and how many micronutrients are needed daily. Vitamins and minerals can be classified as fat-soluble vitamins, water-soluble vitamins, macrominerals, and trace minerals.
