Seafood is very high in vitamin B-12; with the best sources being sardines, salmon, tuna and cod. Scallops, shrimp and also lamb is a great source of vitamin B12 as well. Vegetarians or those who don’t tend to eat very much fish may want to discuss a possible B12 deficiency with a nutrition expert, and consider supplementing.
Sardines and salmon are also among the highest source of omega-3 fats as well, but flax seed and walnuts are even better. Sprinkle walnuts on salads and put flax in your smoothie often to get the anti-inflammatory benefits of these nutrients, and help combat depression and anxiety.
