Dietary Polyunsaturated Fats and Your Cell Membranes

  • James L. Hargrove
Part of the Modeling Dynamic Systems book series (MDS)


It is often said that “one is what one eats.” Think of this in relation to the three macronutrient categories of carbohydrate, protein, and fat. If one eats more carbohydrate, does this change one’s body composition in some fundamental way? More glycogen will be stored in muscle and other tissues, but there will be no other fundamental change in body composition. Similarly, if one eats more protein, only a small part of the excess amino acids is stored as labile protein in liver; the rest is quickly used for energy. Again, there is no fundamental change in one’s body composition, for the amino acids used to make more proteins are assembled using the genetically encoded templates of messenger RNA, and one’s diet does not change that code.
