Vegan Diet Low in Omega-3, B12
February 17, 2011
HANGZHOU, China—Individuals who follow a strict vegan lifestyle have an increased risk of heart-related disease because the diet is critically low in several key nutrients, including iron, zinc, vitamin B12, and omega-3 fatty acids, according to an article published in the Journal of Agricultural and Food Chemistry.
Researchers at Zhejiang University reviewed of dozens of articles published on the biochemistry of vegetarianism over the past 30 years. They found that while a balanced vegetarian diet can provide enough protein, this isn’t always the case when it comes to fat and fatty acids; therefore, vegans tend to have elevated blood levels of homocysteine and decreased levels of HDL cholesterol.
The researchers concluded vegetarians and vegans should increase their dietary omega-3 fatty acids and vitamin B12 by eating more salmon and other oily fish, walnuts and certain other nuts, seafood, eggs, and fortified milk.
