Document Summary
Lifestyle (hunting, gathering, shelter, etc) = high physical activity. Diet = mostly vegetarian diet, intermittent game meat, wild leaves, fruits, etc. Cases of death = accident, illness, starvation, thirst. Lifestyle (growing crops, raising animals) = less physical activity. Diet = mo(cid:396)e (cid:396)elia(cid:271)le sou(cid:396)(cid:272)e of food, (cid:448)a(cid:396)iet(cid:455), (cid:373)eat (cid:272)o(cid:374)su(cid:373)ptio(cid:374), pla(cid:374)t (cid:272)o(cid:374)su(cid:373)ptio(cid:374) Causes of death = deficiency diseases, crop failure, osteoporosis. Lifestyle (big cities, limited living space, sedentary work) = physically inactive. Diet = plentiful, high sugar/fat, low cho/fibre and vegetables. Causes of death = chd, diabetes, obesity, etc. Gl(cid:455)(cid:272)ae(cid:373)i(cid:272) load change in quantity and quality of cho = type 2 diabetes, chd.
