Investigation:
A new study has found out why glucose is so important to fat cells. Research groups have shown how fat cells can protect our bodies against diabetes. Because fat cells control healthy blood sugar and insulin throughout the body, fat cells need only a small portion of sugars from food. The problem in obesity is that it cuts off sugar molecules needed which as a result, blocks the glucose from entering the fat cells. Cells that have trouble taking in sugar, usually leads to diabetes. For the future, scientists will actually investigate fatty acids (glucose metabolism in adipose tissue) and altering fat cells and the molecules they secrete since they are recommended as a healthy part of our diet.
