4. Iodine

Not very popular but one of the major nutrients vegetarians are not getting enough is iodine. Many might have an idea that iodine is not an important nutrient needing the limelight! Well guess what? Iodine is immensely functional. To begin with, it is the prime nutrient needed to convert food into energy. Secondly, iodine plays a big-league role in regulating the thyroid hormone.

Non-vegetarians rack up iodine in posh quantities from the scrumptious seafood. However, vegetarians can stick to the healthy kelp and iodized salt for best help.
