The vegan diet is very rich in some nutrients but not so much in others. Vegan diets can be extremely lacking in the B vitamins, especially vitamin B12, and B6. Protein and iron can be other nutrients that the diet as far as food alone cannot provide all the nutrients that are needed.
Vegan diets are high in vitamins and certain other nutrients. A multi vitamin supplement would not be out of order here that encompassed the necessary B vitamins and iron that the vegan diet may lack at times.
It is very important that any child who partakes of the vegan diet to be supplemented with both the vitamin B complex, with special attention paid to vitamin B12 as their livers do not store that vitamin like an adult liver does.
Vitamin B12 deficiency can lead to pernicious anemia amongst other problems so it is very important for vegan parents to make sure that their children are receiving the proper supplements in order to provide all the needed ingredients and nutrients that a growing child needs.
Protein is another concern on a vegan diet. Granted that tofu is a great source of protein and certain beans and sprouts can become complete proteins when combined with grain. Plant based meat is another good source of protein and you can buy plant based meat online. However, there are very limited resources for protein which may lead to people practicing the vegan diet not eating the proper amounts of protein.
Protein supplements such as powders and shakes can be purchased in health food establishments which can be used by vegans who want to make sure that they have adequate amounts of protein in their diets without eating the same foods over and over that contain protein on a daily basis. This is a good alternative for them to make sure they have adequate protein in the diet.
