A Quick Vegan Guide: Functions and Food Sources of Vitamins

The word “vitamin” comes from the Latin for “vital to life.” These important nutrients help release energy from food, fight infection, protect against damage to cells, promote normal growth and development and generally keep us healthy.

Some vitamins are water soluble, which means they are not stored in the body. Your body uses what it needs and releases excess amounts in your urine, making it necessary to consume these vitamins daily. Examples of water soluble vitamins include Vitamin C and the B vitamins (thiamine, riboflavin, niacin, B6, B12, biotin, folate and pantothenic acid). Others are fat soluble. These vitamins are stored in the body, but you need to eat a certain amount of fat to ensure that they are properly absorbed. Vitamins A, D, E and K are fat-soluble vitamins.

The following is a list of the different functions of some important vitamins and list of food sources for them.

Vitamin A: FUNCTIONS IN THE BODY
  • Aids in normal bone and tooth development
  • Aids in night vision
  • Helps maintain the health of skin and membranes

Some Food Sources dark root vegetables such as carrots and sweet potatoes, pumpkin, cantaloupe, pink grapefruit, tomatoes, broccoli and dark leafy green vegetables including callaloo, dandelion spinach, beet greens, Swiss chard and kale

Vitamin C: FUNCTIONS IN THE BODY
  • Helps in the development and maintenance of bones, cartilage and teeth
  • helps heal cuts and wounds and keeps gum healthy
  • Acts as an antioxidant
  • Aids in iron absorption

Some Food Sources oranges and orange juice, grapefruit and other grapefruit juice, kiwifruit, strawberries, bell peppers, broccoli, Brussels sprouts, potatoes and tomatoes

Vitamin D (the “sunshine vitamin”): FUNCTIONS IN THE BODY
  • Helps the body absorb and use calcium and phosphorus
  • Plays a role in bone and tooth formation and maintenance

Some Food Sources mushrooms (the only plant source of vitamin D), almond milk (original fortified with vitamin D), soy yogurt fortified with vitamin D, ready-to-eat cereals and oatmeal fortified with vitamin D, orange juice fortified with vitamin D

Our bodies can actually make and absorb vitamin D from sun exposure. According the the National Institute of Health, 5 – 30 minutes of sun exposure between 10 am and 3 pm twice a week to the face, arms, legs, or back without sunscreen is usually enough to help boost vitamin D intake. This process varies widely depending on the season, time of day, cloud cover, skin color, and sunscreen use, so eating food sources of vitamin D (such as fortified dairy products, or some mushrooms) is also important. Vitamin D is also available as a dietary supplement.
