Human evolution shows that we are predominately plant based eaters. (34a, 34a1) and human biochemistry has not yet evolved to adapt to an animal based diet explaining the high levels of our morbidity and mortality (34b, 34c) Proof of this lag in evolutionary change is that when patients suffering from dietary causes of cardiovascular disease, stop eating animal products, (including milk, fish, eggs) and processed foods they reverse their disease and heal. (34d, 34e, 34f) These diet related ailments are causing enormous impact on healthcare costs and productivity.
Mageuzi ya binadamu yanaonyesha ya kwamba binadamu kupanda makao walaji (34a, 34a1) na kemia ya binadamu haijabadilika kukabiliana na mlo wa wanyama ikielezea kwa nini kuna kiwango cha juu cha maradhi na vifo (34b, 34c). Ushahidi wa hii bakia ni wa mabadiliko ya kwamba wagonjwa wanaougua kutokana na sababu za mlo wa ugonjwa wa moyo na mishipa, wakiacha kula vyakula vilivyo na mlo wa wanyama, ugonjwa wao unabadili na wanapona. (34d, 34e, 34f). Haya magonjwa yanayotokana na mlo yanasababisha athari kuu kwa gharama ya afya na uzalishaji.
