Vitamins and minerals are essential substances that our bodies need to function normally. They are organic compounds that our bodies use in very small amounts for a variety of metabolic processes. They are required by the body to carry out a range of normal functions, but they are not produced in our bodies and must be derived from food. Vitamins and minerals are sometimes called micronutrients and are needed in small amounts to make our bodies work properly. They are involved in the metabolic processes that enable us to get energy from carbohydrates, protein and fat, which are also known as macronutrients. Different vitamins serve different purposes and contribute to different bodily functions. For example, some vitamins help you resist infections and keep your nerves healthy, while others may help your body get energy from food or help your blood clot properly.

What You'll Learn
Vitamins and minerals are essential micronutrients
Vitamins are tiny substances found in the food we eat. They are made by animals and plants. Vitamins are grouped into two main types, based on how they dissolve and are stored in the body: water-soluble and fat-soluble. Water-soluble vitamins include vitamin C, B2, B6, B12, and folic acid. They dissolve in water and are not stored in the body. Fat-soluble vitamins include vitamin A, D, E, and K. They dissolve in fat and can be stored in the body's fatty tissues and liver for later use.
Minerals are inorganic elements present in the soil and water, which are absorbed by plants or consumed by animals. They are also essential micronutrients that help the body function. Some minerals, like iodine and fluoride, are only needed in trace amounts. Others, such as calcium, magnesium, and potassium, are needed in larger amounts.
A healthy and varied diet that includes all five food groups is usually all that is needed to stay healthy and obtain the necessary vitamins and minerals. Fresh fruits and vegetables are good sources of vitamins, and cooking them may reduce vitamin content. Eating enough fat is essential to a healthy diet, as it helps our bodies absorb vitamins and nutrients. However, it is important to limit fat intake due to its high calorie content.
In some cases, vitamin and mineral supplements may be recommended to correct deficiencies. However, taking supplements without professional advice can be harmful, and it is always best to get nutrients from food whenever possible.

They enable the body to function properly
Vitamins and minerals are essential for the body to function properly. They are organic compounds that our bodies use in very small amounts for a variety of metabolic processes. They are sometimes referred to as micronutrients.
Vitamins and minerals enable the body to perform a range of functions, including helping to fight infection, wound healing, making our bones strong, and regulating hormones. For instance, vitamin C helps to prevent scurvy, while vitamin B3 prevents pellagra. Similarly, vitamin D is vital for bone growth and health, and without it, bones become soft, malformed, and unable to repair themselves normally.
Minerals are inorganic elements found in the soil and water, which are absorbed by plants or consumed by animals. They are also essential for the body to function properly. For example, calcium helps to build strong bones and teeth and regulate heartbeat. Iron is another important mineral that helps prevent anaemia. Zinc is involved in various bodily functions, including growth, development, and immune function.
Vitamins and minerals work together to keep the body functioning properly. For example, zinc helps to produce and transport vitamin A in the body. Similarly, folic acid (vitamin B9) works with vitamin B12 to form healthy red blood cells and prevent anaemia.
A healthy and varied diet that includes fruits, vegetables, whole grains, lean meats, and dairy products can provide the body with the vitamins and minerals it needs to function properly. However, in some cases, vitamin and mineral supplements may be recommended to correct deficiencies.

They cannot be produced by the body
Vitamins and minerals are essential nutrients that the body requires to function properly. They are sometimes referred to as micronutrients as they are needed in small amounts. However, these micronutrients cannot be produced by the body and must be derived from food or supplements.
Vitamins are organic compounds that play a crucial role in various metabolic processes. There are 13 essential vitamins, including vitamins A, C, D, E, K, and the B vitamins (thiamine, riboflavin, niacin, pantothenic acid, biotin, B6, B12, and folate). Each vitamin has specific functions, such as helping to resist infections, keeping nerves healthy, aiding in energy production, and promoting proper blood clotting. For example, vitamin C is essential in preventing scurvy, and vitamin A deficiency can lead to blindness.
Minerals are inorganic elements found in the soil and water, absorbed by plants or consumed by animals. They are classified as either major or trace minerals. Major minerals, such as calcium, magnesium, and potassium, are required in larger amounts. Calcium, for instance, helps build strong bones and teeth and regulates heartbeat. On the other hand, trace minerals like iodine, zinc, and selenium are needed in smaller quantities but are still essential for various bodily functions. Iodine, for example, is necessary for the production of thyroid hormones, which maintain healthy cells and metabolic rates.
While a healthy and balanced diet that includes fruits, vegetables, whole grains, lean meats, and dairy products should provide sufficient vitamins and minerals, some individuals may require additional support. Vitamin and mineral supplements can be beneficial in addressing specific deficiencies, especially during certain life stages, such as pregnancy or for older adults. However, it is important to consult a healthcare professional before taking supplements, as excessive intake can be harmful.

They must be derived from food
Vitamins and minerals are essential micronutrients required by the human body to function properly. However, the body cannot produce these micronutrients by itself and, therefore, they must be derived from food. Vitamins are organic substances that are either fat-soluble or water-soluble. Fat-soluble vitamins, such as vitamins A, D, E, and K, dissolve in fat and can accumulate in the body. Water-soluble vitamins, such as vitamin C and the B-complex vitamins, must dissolve in water before being absorbed by the body and cannot be stored. As a result, any excess water-soluble vitamins are excreted through urine.
Minerals, on the other hand, are inorganic elements found in soil and water, which are absorbed by plants or consumed by animals. Essential minerals include calcium, iron, and potassium, which are necessary for building strong bones and teeth and converting food into energy. A balanced diet that includes a variety of fruits, vegetables, whole grains, beans, legumes, low-fat protein, and dairy products can provide the body with the necessary vitamins and minerals.
The National Academy of Medicine in the United States develops Dietary Reference Intakes (DRIs) for vitamins and minerals, providing guidelines specific to age, gender, and life stages. These guidelines are based on reports of deficiency and toxicity for each nutrient. While most people can obtain the required nutrients from a healthy diet, some may choose to take vitamin and mineral supplements, although advice should be sought before doing so.
Vitamins and minerals are essential for maintaining good health, and their discovery has helped us understand the importance of a varied and balanced diet. By including a range of food groups in our diet, we can ensure that our bodies receive the micronutrients they need to function optimally.

Deficiency can lead to diseases
A deficiency in vitamins and minerals can lead to a variety of diseases and health problems. Vitamins and minerals are essential micronutrients that our bodies require in small amounts to function properly and maintain overall health. While most vitamins and minerals are derived from our diet, some people may require supplements to meet their nutritional needs.
Vitamin B12 deficiency is one of the most common deficiencies, especially among vegetarians, vegans, and older adults. It can lead to blood disorders, impaired brain function, and elevated homocysteine levels, which are risk factors for various diseases. Vitamin B9, also known as folate, is another critical nutrient, and its deficiency can cause birth defects during pregnancy and increase the risk of central nervous system defects in unborn babies. Folate deficiency is also associated with an increased risk of developing folate deficiency anaemia, characterised by fatigue, shortness of breath, and dizziness.
Vitamin A deficiency is prevalent in many developing countries and can result in eye damage, blindness, suppressed immune function, and increased mortality among women and children. Similarly, a lack of vitamin C can lead to scurvy, a disease characterised by fatigue, weakness, and gum and tooth infections.
Mineral deficiencies can also have significant health consequences. Iron deficiency, for example, is common and can lead to iron deficiency anaemia, affecting both adults and children. Zinc deficiency can impair growth and development and compromise immune function. Magnesium deficiency is prevalent in Western countries and is associated with type 2 diabetes, metabolic syndrome, heart disease, and osteoporosis.
Overall, vitamin and mineral deficiencies can lead to a range of diseases and health issues, and it is important to maintain a balanced diet or take supplements to prevent these deficiencies.
