Dietary carbohydrates and fats

"Dietary carbohydrates and fats" refers to two primary types of macronutrients required in large amounts for human nutrition. Carbohydrates comprise sugars, starches, and fiber, serving as a main energy source through their breakdown to glucose, which is especially vital for brain and nerve cell function[1][4][7]. Fats (lipids) also provide energy, at a higher caloric density than carbohydrates, and are essential for cellular structure, insulation, and the production of bioactive molecules like hormones and eicosanoids[3][10]. Both classes of molecules are necessary for health but excessive intake, particularly of refined carbohydrates and certain fats, is implicated in chronic diseases such as obesity, diabetes, and cardiovascular disorders[4][10]. Diverse subtypes (e.g., saturated, unsaturated fats; simple, complex carbohydrates) have different metabolic and health impacts.
