Nutrition and obesity have a remained a pivotal point for emotive discussions because weight issues can be very personal and quite difficult to get unbiased opinions. It is true that the world is growing fatter on a daily basis, but human nutrition is quite a complex phenomenon affected by numerous factors such as genetic endowment and the environmental milieu. The first question arises from a fact that is often taken for granted. Most people would easily assume that a better nutrition means a superior intellect or cognition. There is no evidence to support this. We may grow taller with good food but the essential functioning of the brain that defines our intelligent quotient appears to be unaffected by the quality or amount of food that we consume.
A better income should simply manifest itself with more adipose tissue around the trunk. This is not true, at least not for the men. The greater the purse, the more appropriate the weight is for men. The simple explanation is that the toils involved in gathering the income help disperse the excess calories. While the ladies in this setting put on weight because the physical and mental exertion is often not shared between both of them.
Beauty they say is in the eyes of the beholder. It is expected that love and affection should be blind to weight. This is not particularly true, particularly in women. Ladies who are in a relationship or married are significantly slim compared to their single counterparts. Marriage appears to exert its own negative effect on weight. Married women have a higher weight when compared to those unmarried women who are in a relationship.
In young people, peer pressure does not appear to affect the body weight of men unlike is the case in substance abuse. This effect is reserves for women. It appears that because women are more conscious about their body weight and hence more receptive to peers pressure than men.
As nutrition and the weight story continue to change, what has provoked a renewed interest is the advantages of breast milk over infant nutrition. This specie specific fluid is associated with better cognitive development in breastfed individuals. Until we disprove this, the tendency should be to encourage it.
