The Maasai people of East Africa live in southern Kenya and northern Tanzania along the Great Rift Valley lands. This group of peoples till date haven't been diagnosed with, high blood sugar, High blood pressure, insulin resistance, type 1 or 2 diabetes, cancer, hypertension, kidney or liver disease, etc. Traditionally, the Maasai diet consisted of raw meat, raw milk, and raw blood from cattle, buttermilk, Butter ( mostly Fats & 1st class Protein), as we can see there are no Grains, Sugars, Starchy vegetables, Sweet Fruits, Burgers, Pizza, Macaroni, Beagle, sweet dessert, etc. in their diets. In the summer of 1935 Dr. Weston A. Price visited the Maasai and reported that according to Dr. Anderson from the local government hospital in Kenya most tribes were disease-free. Many had not a single tooth attacked by dental caries nor a single malformed dental arch. He attributed that to their diet consisting of (in order of volume) raw milk, raw blood, raw meat and some vegetables and fruits, although in many villages they do not eat any fruit or vegetables at all. He noted that when available every growing child and every pregnant or lactating woman would receive a daily ration of raw blood. Butter is also an important infant food." Most of the milk is consumed as fermented milk or buttermilk or curd (which converts lactose(one of a form of Sugar) into Lactic acid). Electrocardiogram tests applied to 400 young adult male Maasai found no evidence of heart disease, abnormalities or malfunction. These findings were ascribed to the amazing fitness of morans, which was evaluated as "Olympic standard". From above mentioned evidence we can understand that what is going wrong with most of our diets (which mostly consists of Carbohydrate & Sugars), who is main culprits behind, whatever metabolic disease & illness most of the people suffering from.
