Enjoying some chicken breast or thighs is a good way to get some vitamin B12 into your diet. 1 cup, or 140g, contains around 11% vitamin B12. Along with B vitamins, chicken is very high in protein. Chicken also contains iron, vitamin B6, and phosphorus. As an added bonus, chicken is great for all kinds of meals. You can make a chicken salad, stew, or even grill it. Whatever you may like, there’s no doubt that chicken will go good with it.
