5. Vitamin B12
This vitamin is an essential component to healthy brain function. It not only helps people cope with depression, but it can also prevent dementia and confusion. Unfortunately, there are many people that suffer from a vitamin B12 deficiency such as the elderly, those with gastrointestinal conditions or pernicious anemia, and vegetarians and vegans. The elderly lack sufficient amounts of hydrochloric acids in their stomachs which is what helps absorb this vitamin, and vegetarians and vegans may not be getting enough vitamin B12 since it is found primarily in animal products. Because of its importance, it is recommended that you take a vitamin B12 supplement in addition to including foods that are rich in vitamin B12.
Foods that contain high levels of vitamin B12 include red meat, fish, poultry, milk, eggs, and fortified cereals.
