Five crucial nutrients that are only found in meat, fish, and eggs

The human brain is the most complex organ in your body, and it requires a lot of energy. The brain represents only 2 percent of our body weight, but uses 20 percent of the body's entire energy supply.

For all of documented history, humans have been omnivores, meaning that we eat meat as well as plants. These foods contain nutrients that are critical for the full functionality of the brain.

Here are five nutrients which are very important for brain function and presence of mind. You will only find them in animal food sources.

1. Vitamin B12

This vitamin is of critical importance for a good nervous system and brain health. It is found only in foods of animal origin. A lack of vitamin B12 can lead to the development of clinical symptoms after 5 or 6 years of deficiency or decreased absorption. Getting enough vitamin B12 is essential for normal haematogenesis and neurobiological functionality. Deficiency of this vitamin leads to macrocysticity, megaloblastic aneemia, and/or neurological symptoms due to the deterioration of the spinal cord, brain, and optic and peripheral nerves. Therefore, vegetarians must consume B12 food supplements.

2. Creatine

Creatine is an important nutrient for both the muscles as well as the brain. It helps provide energy to both of them. Studies have shown that vegetarians usually suffer from creatine deficiency, which is the reason why vegetarians lose muscle mass. Brain creatine deficiency syndrome occurs in patients who experience varying degrees of mental underdevelopment, the development of expressive speech disorders, autistic behavioral traits, and a decrease in muscle tone or inflammation in the muscles.

3. Vitamin D3

A very large part of the world population has vitamin D3 deprivation. Again, it is found only in foods of animal origin. Scientific studies have proven that vitamin D3 is important for the correct functionality of bone tisuse, and the development of the brain during childhood. Low levels of vitamin D are also associated with diabetes, autoimmune diseases, infectious diseases, and the development of epilepsy. It’s also an essential vitamin for the treatment of asthma, tuberculosis, and other infectious diseases. Vitamin D deficiency may increase the chances of falling victim to intestinal cancer, high blood pressure, and cardiovascular diseases.

4. Carnosine

Carnosine is a protein found in animal cells. This nutrient can reduce damage in the body caused by elevated blood sugar levels. It also has anti-aging effects.

5. DHA

DHA, or docosahexaenoic acid, is an omega-3 fatty acid. It’s of critical importance to proper brain function. It is found mostly in foods of animal origin, such as fatty fish. Studies have shown that vegans and vegetarians suffer from a deficiency of this substance.

If your thoughts drift towards cutting off meat from your diet as a weight loss strategy, consider instead the option of consuming a healthier balanced diet. That way you don't have to eat food supplements, and you can be sure that your body and brain will get all the nutrients necessary for good health in the most natural manner.
