The skin is regenerated in 28 days, the bones takes about 10 years, the red blood cells live for about four months, the cells of the colon are rejuvenated every three to four days, and as far as brain cells, they cannot regenerate and what we get at birth, we got (so they should be kept).
Health means a good regeneration of organs, because the old cells have replaced in order to continue living. Food is very important for regeneration of the bodies and it is useful to know which foods are most helpful.
There is a wide range of natural compounds that act on the nerve regenerating. A study from 2010 published in Rejuvenation Research shows that the combination of blueberries, green tea and carnosine (found in pork, beef, fish) helps nerve regeneration and stem cells in animals with neurodegenerative diseases.
Other substances with similar facts are: curcumin (turmeric root plants), apigenin (compound found in celery, parsley, artichokes), resveratrol (red wine, red grapes, dark chocolate), jelly theanine (green tea) and coffee.
There are other substances that help heal nerve repairing the sheath of nerve fibers myelin. Also, music and falling in love have a positive effect on the regeneration and recovery of neurons.
Glycyrrhizin is a compound found in licorice root, and which, according to one study proved to be a great stimulus to regeneration in animals in which was surgically removed on a part of the liver. Other substances that help regenerate the liver are: carvacrol (from oil of oregano), curcumin (turmeric root plants), ginseng, Korean artichoke vitamin E (tofu, spinach, almonds, sunflower seeds, avocado, shrimp, fish, olive oil, broccoli, pumpkins and squash).
Beta cell regeneration
Beta cells in the pancreas produces insulin. With the following compounds was successfully experimented in order to help diabetics: black cumin, vitamin D (fish, caviar, eggs, cheese), curcumin (turmeric root), arginine (red meat, soy, eggs, seafood, sesame) , avocado, bitter melon, chard, corn silk, stevia, sulforaphane (broccoli sprouts, kale, brussels sprouts, cabbage, cauliflower).
One of the compounds that regenerates hormones, which are weakened by losing electrons, is the vitamin C (peppers, kale, kiwi, broccoli, strawberries, oranges, peas). This vitamin has the ability to restore form and function of estradiol (estrogen, E2), progesterone and testosterone, which can be a good addition or replacement of hormone therapy.
Until recently it was thought that muscle tissue is not able to regenerate. New research shows that there are compounds to stimulate the building of the heart muscle cells that make up a healthy heart tissue.
What to eat? Resveratrol (red wine, red grapes, dark chocolate), Siberian ginseng, N-acetyl-cysteine (oatmeal, pork, chicken, wheat germ, cheese)
Regeneration of cartilage, the joints of the spine
Curcumin and resveratrol are proven to be effective with the recovery from spinal cord injury, while for osteoarthritis, a degenerative joint disease, there is a wide range of potentially regenerative substances found in nettle, fish oil and other foods rich in vitamin E.
