I’m currently Rewiring Your Brain, which is a fascinating book on how can you go about change how you feel about certain things, and remain optimistic throughout difficult times.
The book touches upon good dietary habits in quite a lot of detail and I was quite amused to come across how the term redneck came to be.
Vitamin B3 (niacin) is involved in as many as forty different biochemical reactions in the body and the brain. One of its principal effects is to participate in the process of increasing red blood cells, which carry oxygen to the brain.
It also is involved in the pathways for ATP, which, as I mentioned earlier, is the cells’energy substance. In moderate doses B3 lowers blood cholesterol, and in high doses it causes dilation of the blood vessels, increased blood flow to the brain, and decreased blood pressure.
Niacin can be manufactured from L-tryptophan, which, as I have noted, is a precursor to serotonin. The amount of L-tryptophan that is converted to niacin depends on your diet. Niacin and L-tryptophan should be balanced in your diet. A severe deficiency of niacin causes a condition called pellagra, which leads to dementia, diarrhea, and dermatitis. The dermatitis symptoms include a condition of extremely red skin.
Here’s a little factoid with which you can entertain people at a party: the term redneck has its origin in niacin-deficient white field-workers. Due to the deficiency, they developed a red “necklace”on the skin of their necks.
