It is the seventh leading reason behind death in the country and can cause serious health issues including heart disease, blindness, kidney failure and amputations. Among adults, diabetes improved in men and women and in all age groups, but still disproportionately affects the elderly. Almost 25 % of the population 60 years and old had diabetes in 2007. After adjusting for populace age differences between several groups, the rate of diagnosed diabetes was highest among American Indians and Alaska Natives . This is accompanied by blacks and Hispanics , which include rates for Puerto Ricans , Mexican Americans , and Cubans . By comparison, the rate for Asian Us citizens was 7.5 %, with whites at 6.6 %..Unexpectedly, the authors discovered the obese people experienced higher levels of particular types of lipids made up of polyunsaturated fatty acids within their adipose cells than did their nonobese twins. This finding is normally interesting because cell membranes are primarily made up of lipids, and different lipids can transform a membrane’s physical properties, such as fluidity. When the authors used computers to model the effect of these different lipids on adipose cell membranes, they found that the fresh lipids observed in the cells of the obese twins well balanced each other in such a way that general membrane fluidity was unaffected.
