Describe any 3 challenges that a vegan faces when developing an eating plan that ensures nutritional adequacy
She will need to get enough vitamin B12, vitamin D, and zinc from her foods or from supplements since these nutrients are more abundant in animal-based foods.
She will need to obtain enough non-heme iron from plant sources to ensure adequate iron intake. Meats contain heme iron, which is more absorbable than non-heme. She will want to consume more vitamin C to help her absorb the non-heme iron more efficiently.
She will need to get enough omega-3 fatty acids, since they come primarily from fish. She can find these fatty acids in flaxseeds and walnuts, but she will want to make sure that she does not take in large portions with excessive calories.
She will need to make sure that she receives enough calcium from a variety of plant sources since she does not eat dairy products.
