Sea vegetables have a high mineral and nutritional profile. For centuries, Oriental medicine has recognized that sea vegetables contribute to general well-being and especially to the health of the endocrine and nervous systems. Over the last few decades, medical researchers have discovered a diet that includes sea vegetables reduces the risk of some diseases and helps the body eliminate dangerous toxins. In fact, surveys show that people living in areas where sea vegetables are regularly included in the diet tend to live longer, healthier lives.
Edible plants from the sea also contain important vitamins including vitamin A (in the form of beta-carotene), B1, B2, B6, niacin, vitamin C, pantothenic acid, and folic acid. Analysis has shown trace amounts of vitamin B12, which rarely occurs in land vegetables. Sea vegetables offer other health benefits.
