Your data is mostly lies. The actual fact is that, other than iodine deficiency, malnutrition has to be extreme and prolonged to cause developmental problems. Not even the worst privation of WWII in Europe caused noticeable developmental changes in children compared to the pre- and post-war cohorts. The data on American children show the opposite of starvation. IQs continue to climb, height and growth rate remain high, and the age of puberty continues to fall. This is especially true for the "deprived" Africans in your references, who have the fastest IQ growth of any Americans and an astonishingly low age of puberty (8 and falling for girls). Your references trot out the high rate of welfare handouts to the poorest Africans. That's because they have an average IQ below 80 and most of their jobs have been taken over by machines. This is the expected transition to a post-scarcity society.
