What are vitamins and minerals?


Vitamins and minerals are needed to make your body work properly. Vitamins come from plants and animals, while minerals originally come from the earth.

Most people can get all the vitamins and minerals they need from the 5 food groups in a balanced diet. However, some groups in the community are more at risk of developing deficiencies.

Vitamins are found in:

  • ➥ fresh foods
  • ➥ frozen foods
  • ➥ canned foods

An example is Vitamin C. It is found in many fruits. Some vitamins can be lost by cooking in water. Fresh fruit and uncooked vegetables are good sources of vitamins.

Minerals can be found in food and in water. An example of a mineral is calcium. It is found in milk, fish and some plant foods like green vegetables and sesame seeds.
Every single day, your body orchestrates an intricate symphony of biological processes, tirelessly generating skin, muscle, and bone. It diligently manufactures rich red blood cells, ensuring the delivery of essential nutrients and oxygen to far-flung corners of your body, while simultaneously transmitting nerve impulses along extensive networks spanning thousands of miles within your brain and body. Moreover, it meticulously formulates chemical messengers that traverse between organs, issuing vital instructions crucial for sustaining your life.

However, to execute these remarkable feats, your body relies on a fundamental requirement: raw materials. These encompass a minimum of 30 essential vitamins, minerals, and dietary components that your body urgently needs but cannot produce in adequate quantities by itself.

Vitamins and minerals stand as undisputed cornerstones of nutrition, performing a multitude of indispensable roles within the body. They serve as pillars in fortifying bones, accelerating wound healing, and fortifying the immune system. Furthermore, they play pivotal roles in converting food into energy and repairing cellular damage, ensuring the seamless functioning of your body's intricate machinery.

Water-soluble vitamins


Water-soluble vitamins are found in the watery parts of the foods you eat. They get into your bloodstream as your body digests food or when you take a supplement that dissolves.

Since a lot of your body is made of water, these vitamins move around easily. Your kidneys keep tabs on the levels of these vitamins, getting rid of any extras through your urine.

Type of Water-soluble vitamins

    B vitamins:
  • ➥ Biotin (vitamin B7)
  • ➥ Folic acid (folate, vitamin B9)
  • ➥ Niacin (vitamin B3)
  • ➥ Pantothenic acid (vitamin B5)
  • ➥ Riboflavin (vitamin B2)
  • ➥ Thiamin (vitamin B1)
  • ➥ Vitamin B6
  • ➥ Vitamin B12
  • ➥ Vitamin C

What do'water soluable Vitamin' do
Even though water-soluble vitamins perform various tasks in the body, one of their primary functions is aiding in the release of energy stored in the food you consume. Additionally, they contribute to maintaining the health of your tissues. Here are some examples of how different vitamins contribute to your overall well-being:

1. Release energy. Several B vitamins are key components of certain coenzymes (molecules that aid enzymes) that help release energy from food.
2. Produce energy. Thiamin, riboflavin, niacin, pantothenic acid, and biotin engage in energy production.
3. Build proteins and cells. Vitamins B6, B12, and folic acid metabolize amino acids (the building blocks of proteins) and help cells multiply.
4. Make collagen. One of many roles played by vitamin C is to help make collagen, which knits together wounds, supports blood vessel walls, and forms a base for teeth and bones.

Fat-soluble vitamins


Fatty foods and oils are reservoirs for the four fat-soluble vitamins. Within your body, fat tissues and the liver act as the main holding pens for these vitamins and release them as needed.

    Type of Fat-soluble vitamins
  • ➥ Vitamin A
  • ➥ Vitamin D
  • ➥ Vitamin E
  • ➥ Vitamin K

What do 'fat soluable Vitamins' do
Together this vitamin quartet helps keep your eyes, skin, lungs, gastrointestinal tract, and nervous system in good repair. Here are some of the other essential roles these vitamins play:

1. Build bones. Bone formation would be impossible without vitamins A, D, and K.
2. Protect vision. Vitamin A also helps keep cells healthy and protects your vision.
3. Interact favorably. Without vitamin E, your body would have difficulty absorbing and storing vitamin A.
4. Protect the body. Vitamin E also acts as an antioxidant (a compound that helps protect the body against damage from unstable molecules).

Major minerals


The body requires significant quantities of major minerals, which it stores for future use. While these minerals are not more crucial to your health than trace minerals, they are simply found in larger amounts within your body.

Major minerals move through the body via different pathways. For instance, potassium is rapidly absorbed into the bloodstream, where it freely circulates and is eliminated by the kidneys, akin to water-soluble vitamins. Conversely, calcium behaves more similarly to fat-soluble vitamins, necessitating a carrier for absorption and transport.

    Type of Major minerals
  • ➥ Calcium
  • ➥ Chloride
  • ➥ Magnesium
  • ➥ PhosphorusK
  • ➥ Potassium
  • ➥ Sodium
  • ➥ Sulfur

What do 'major minerals' do
Having too much of one major mineral can result in a deficiency of another. These sorts of imbalances are usually caused by overloads from supplements, not food sources. Here are two examples:

1. Salt overload. Calcium binds with excess sodium in the body and is excreted when the body senses that sodium levels must be lowered. That means that if you ingest too much sodium through table salt or processed foods, you could end up losing needed calcium as your body rids itself of the surplus sodium.
2. Excess phosphorus. Likewise, too much phosphorus can hamper your ability to absorb magnesium.

Trace Minerals


These are the trace minerals

    Type of Major minerals
  • ➥ Chromium
  • ➥ Copper
  • ➥ Fluoride
  • ➥ Iodine
  • ➥ Iron
  • ➥ Manganese
  • ➥ Molybdenum
  • ➥ Selenium
  • ➥ Zinc

What do 'major minerals' do
Trace minerals carry out a diverse set of tasks. Here are a few examples:

1. Iron is best known for ferrying oxygen throughout the body.
2. Fluoride strengthens bones and wards off tooth decay.
3. Zinc helps blood clot, is essential for taste and smell, and bolsters the immune response.
4. Copper helps form several enzymes, one of which assists with iron metabolism and the creation of hemoglobin, which carries oxygen in the blood.

The other trace minerals perform equally vital jobs, such as helping to block damage to body cells and forming parts of key enzymes or enhancing their activity.

Antioxidants


An antioxidant is a broad term used to describe any substance capable of neutralizing unstable molecules like free radicals, which can cause damage to DNA, cell membranes, and various cellular components.

Your body's cells naturally produce ample antioxidants to combat these threats. Additionally, the foods you consume, along with potentially some supplements, serve as additional sources of antioxidant compounds. Examples of antioxidants found in food include carotenoids (such as lycopene in tomatoes and lutein in kale) and flavonoids (such as anthocyanins in blueberries, quercetin in apples and onions, and catechins in green tea). Furthermore, vitamins C and E, as well as the mineral selenium, possess antioxidant properties.

Why free radicals may be harmful
Free radicals are produced naturally as a result of energy metabolism and are also generated by exposure to ultraviolet rays, tobacco smoke, and air pollution. Due to their incomplete electron configuration, they are inherently unstable, leading them to snatch electrons from other molecules, resulting in damage to those molecules.

Although free radicals are notorious for causing cellular harm, they also serve a beneficial role. When immune system cells mobilize to combat invaders, the oxygen they utilize produces a cascade of free radicals that actively eliminate viruses, bacteria, and impaired body cells in what is known as an oxidative burst. Vitamin C plays a crucial role in neutralizing these free radicals, thereby mitigating their destructive effects.

How antioxidants may help
Trace minerals carry out a diverse set of tasks. Here are a few examples:

Antioxidants possess the ability to counteract invaders like free radicals by relinquishing some of their own electrons. When a molecule of vitamin C or E performs this act of sacrifice, it can potentially safeguard vital proteins, genes, or cell membranes from harm, thereby interrupting a cascade of damage that might otherwise affect numerous cells.

It's crucial to understand that the term "antioxidant" denotes a chemical characteristic rather than a singular nutritional trait. Each nutrient exhibiting antioxidant properties also encompasses various other functions and should be evaluated individually. Additionally, the context in which these nutrients operate is significant; for instance, while vitamin C acts as an antioxidant in certain scenarios, it may function as a pro-oxidant in others.
