The orange group (carrots, squash, sweet potatoes etc) get their colour from Beta Carotene which gets converted to vitamin A by the cells in the body. Preformed Vitamin A can be found in meat and dairy products, it also acts as a hormone (retinoic acid) and is important for your vision and to normalize cells. Vitamin A is concentrated mostly at the back of the retina as CIS Retinal where light hits the to create a visual image which is then sent to the brain. The images are then organized and made 3D and full colour. The earliest signs of Vitamin A deficiency is night blindness and a more serious deficiency could lead to a total loss of sight. The Yellow/Orange Group is formed from citrus fruits. Many fruits we have today have come from crossing lemons, Mandarin oranges and the pomelo which is a type of grapefruit. This group contributes to the vitamin C and citrus flavanoids that we need. Humans and primates all lost the genes to create vitamin due to the abundance of it in the diet of ancient man. It's an key antioxidant and should be included in everyone's diet. This particular family of citrus flavanoids can be found in the juice, pulp and peel of any citrus fruit. If you squeeze the peel, you'll notice some juice comes out separate from the meat of the fruit. This contains Geranoil and Limonen which are fat soluble flavours added to fruit juices to give it a fresh taste. #poweredbyherbalife #orangegroup #phytonutrients #vitamina #info #learning #drdaveheber (at Brighton)
