We're not vegans, and none of us on raw paleo diets get protein deficiencies. I don't know about you. I'm not sure any of us would touch an onion. We definitely are not big on grain, to say the least. I know my nails got stronger and younger looking by eating RAFs.
diet should include a lot of fruits and raw vegetables so that they get the required vitamins, minerals and enzymes. Eat food that is rich in silicon like broccoli, fish and onions. Eat foods rich in biotins like whole grains. Drink plenty of water and other fruit juices. Food rich in zinc and vitamin B will strengthen your nails. Fresh carrot juice rich in calcium and phosphorous is perfect for strengthening nails. In addition remember the following things:
* Lack of vitamin A and calcium in your body causes dryness and brittleness.
* Lack of protein, folic acid and vitamin C causes hangnails.
* White bands across the nails are a result of protein deficiency.
