What are the Sources of Vitamin D?

Presentation Transcript

  1. What are the Sources of Vitamin D? Vitamin D is the only nutrient your body produces when exposed to sunlight. In this Presentation we will be discussing about some of the top sources of Vitamin D.

  2. What is Vitamin D? Vitamin D is a group of fat-soluble secosteroids responsible for increasing intestinal absorption of calcium, magnesium, and phosphate, and many other biological effects. In humans, the most important compounds in this group are vitamin D₃ and vitamin D₂. The major natural sources of vitamin D is synthesis of cholecalciferol in the lower layers of skin epidermis through a chemical reaction that is dependent on sun exposure (specifically UVB radiation). Vitamin D from the diet, or from skin synthesis, is biologically inactive. It is activated by two protein enzyme hydroxylation steps, the first in the liver and the second in the kidneys.

  3. Sources of Vitamin D Salmon Canned tuna Egg yolks Fortified foods

  4. 1. Salmon Salmon is a popular fatty fish and great source of vitamin D. According to the United States Department of Agriculture (USDA) Food Composition Database, one 3.5-ounce (100-gram) serving of farmed Atlantic salmon contains 526 IU of vitamin D, or 66% of the DV Whether the salmon is wild or farmed can make a big difference. On average, wild-caught salmon packs 988 IU of vitamin D per 3.5-ounce (100-gram) serving, or 124% of the DV. Some studies have found even higher levels in wild salmon — up to 1,300 IU per serving

  5. 2. Canned tuna Many people enjoy canned tuna because of its flavor and easy storage methods. It’s also usually cheaper than buying fresh fish. Canned light tuna packs up to 268 IU of vitamin D in a 3.5-ounce (100-gram) serving, which is 34% of the DV. It’s also a good source of niacin and vitamin K. Unfortunately, canned tuna contains methylmercury, a toxin found in many types of fish. If it builds up in your body, it can cause serious health problems

  6. 3. Egg Yolks People who don’t eat fish should know that seafood is not the only source of vitamin D. Whole eggs are another good source, as well as a wonderfully nutritious food. While most of the protein in an egg is found in the white, the fat, vitamins, and minerals are found mostly in the yolk. One typical egg yolk contains 37 IU of vitamin D, or 5% of the DV. Vitamin D levels in egg yolk depend on sun exposure and the vitamin D content of chicken feed. When given the same feed, pasture-raised chickens that roam outside in the sunlight produce eggs with levels 3–4 times higher

  7. 4. Fortified foods Natural sources of vitamin D are limited, especially if you’re vegetarian or don’t like fish. Fortunately, some food products that don’t naturally contain vitamin D are fortified with this nutrient. Some of the best fortified foods are: Cow Milk Soy Milk Orange Juice Oat Meatl
