Milk in the island of Chole [Tanzania] is high in lauric, myristic, arachidonic and docosahexaenoic acids, and low in linoleic acid reconstructed diet of infants born to our ancestors living in tropical coastal regions

BACKGROUND: We need information on the diet on which our genes evolved. OBJECTIVE: We studied the milk fatty acid FA] composition of mothers living in the island of Chole Tanzania, Indian Ocean]. These mothers have high intakes of boiled marine fish and coconut, and consume plenty amount of fruits and vegetables. DESIGN: The outcome was compared with three fish-eating tribes living along Tanzanian freshwater lakes Kerewe, Nyakius, Nyiramba], four tribes living in the Tanzanian inland Hadzabe, Maasai, Sonjo, Iraqw] and our milk FA database. RESULTS: Milk from Chole contained high levels of 12:0 20.17 g%], 14:0 21.19], 12:0/14:0 ratio 0.92 g/g], arachidonic acid AA, 0.50 g%] and docosahexaenoic acid DHA, 0.73], but low levels of linoleic acid LA, 4.23]. The combination of a high medium chain fatty acid MCFA;
