The Rising Tide of Vitamin B12 Deficiency

The Rising Tide of Vitamin B12 Deficiency



With the current trend towards veganism gathering more and more pace (see our recent article on vegan fish) it is important to be clear about some of the health issues around it.



In most cases veganism, without hefty supplementation, leaves the body deficient in many vitamins and minerals. 



This is a growing issue for the public to deal with and some education is important in terms of what can combat the deficiency. The good news is that fish, and especially shellfish, are some of the highest B12-packing foods of all.



Foods that  are particularly high in B12 include the following:

◦ Clams

◦ King Crab

◦ Eggs

◦ Yoghurt

 ◦ Liver

◦ Mackerel

◦ Beef

◦ Salmon

◦ Tuna

◦ Trout



So next time you or a friend are aware of needing to boost your B12, remember to add shellfish to your diet and take advantage of its high proportions of essential nutrients.
