For example, the World Health Organization recommends keeping added sugar intake to 10% of total calories. For the average 2000 calorie-diet that's a maximum of 50 grams. The American Heart Association recommends 6 teaspoons of sugar for women and 9 for men (1 teaspoon of sugar has about 4g of sugar).
In developmental biology, cellular differentiation is the process by which a less specialized cell becomes a more specialized cell type. Different tissues have different kinds of cells.
With a few exceptions, cellular differentiation almost never involves a change in the DNA sequence itself. Thus, different cells can have very different physical characteristics despite having the same genome. A cell that can differentiate into all cell types of the adult organism is known as pluripotent.
