10 Common Nutritional Deficiences

In western societies nutritional deficiencies aren't too common, but are generally present in sub-populations.

Below are 10 common nutritional deficiencies and the daily recommended amounts for adults by the US Government.

Calcium (mineral)

Overview: Calcium is essential in promoting optimal bone structure and support. The Journal of the American College of Nutrition noted that calcium deficiency is most common in subpopulations that include older adults, teenagers, minorities, and those who are low income and overweight and/or obese. However, excess consumption should be guarded as calcium supplements have been found to cause kidney stones. Recommended daily amount: 800-1,000mg males / 800-1,000mg females (800mg pregnant, 800mg lactating)

Food sources: Dairy (yoghurt, cheese, milk), sardines, spinach, kale, soybeans

Vitamin A (fat soluble vitamin)

Overview: Vitamin A is essential for vision as it's shown to protect against cataracts and plays an important role in bone growth. Recommended daily amount: 900mcg males / 700mcg females (750-770mcg pregnant, 1,200-1,300mcg lactating)

Food sources: Liver and fish oils

Folate / Vitamin B9 (water soluble vitamin)

Overview: Folate is vital for new cell creation. While commonly used by pregnant women, as it's shown to reduce birth defects, it can also help lower the risk of heart disease, colon cancer, and breast cancer. Recommended daily amount: 320mcg males / 320mcg females (520mcg pregnant, 450mcg lactating)

Food sources: Spinach, broccoli, asparagus, mushrooms, liver, dry beans and peas

Vitamin B12 (water soluble vitamin)

Overview: Vitamin B12 assists in new cell formation, and may reduce the risk of heart disease. It can also help regulate sleep and moods, improves cognitive ability, and supports a healthy immune system. Since vitamin B12 is water soluble, it's easily dissolved in water, but can be stored in the liver. Recommended daily amount: 1.5-2.0mcg males / 1.5-2.0mcg females (2.2mcg pregnant, 2.4mcg lactating)

Food sources: Animal products including meat, milk, cheese, eggs
