V is for Vitamins
V is for Vitamins
By Megan Barnes, Dietetic Intern
Vitamins are micro-nutrients our body cannot produce on its own. Instead, we need the help from the foods we eat to consume the vitamins necessary for normal bodily function. Vitamins are categorized by the process of which they are digested and absorbed in the body. Fat-soluble vitamins need to be consumed with a fat source for optimal absorption and utilization while water-soluble vitamins are absorbed with water present.
Vitamins are in many foods including fruit, vegetables, dairy, oils, nuts and seeds, beans, whole grains, and protein. Try to eat a variety from all food groups to get all your essential nutrients!
