Maybe these people should eat meat. They are clearly missing some nutrient in their diet. Why would you do this to yourself?
From Memory Foundation:
Protein is brain-food at its finest!
Proteins in our diet affect brain performance because they provide the amino acids (simply put, protein is made of amino acids) that make up our neurotransmitters. Think of neurotransmitters as biochemical messengers whose job it is to carry signals from one brain cell to another. These brain cells then transmit various signals to the different parts of the body to carry out their individual tasks. The better these messengers are fed, the more efficiently they deliver the goods. (Think Mother telling daughter to clean her room, and daughter then paying younger brother to do it – the more he’s paid, the cleaner the room!). You can see why it’s so important to be eating plenty of good protein – without it, the messengers won’t be working fast enough to keep your mind and memory sharp!
Protein – amino acids – are also essential for our happiness. When we don’t eat enough good protein, the brain can’t produce enough neurotransmitters such as serotonin, which is one of the main chemicals which regulates our moods. Some doctors practising in natural medicine believe that amino acid therapy is more effective in some cases than the traditional drugs that are used to treat depression. Eating good sources of protein helps to boost our levels of serotonin and dopamine and this is really important as these help to boost energy, mental clarity, and basically make you feel happier as well as regulate pain, reduce anxiety, initiate deep sleep. Char grilled chicken fillet anyone?
