: Dissolves in water to form a viscous gel, slowing gastric emptying and delaying glucose absorption, which stabilizes postprandial blood glucose. It also binds bile acids in the intestinal lumen, effectively lowering circulating serum cholesterol levels.

Saturated fatty acids (mostly animal sources), monounsaturated (MUFAs), polyunsaturated (PUFAs), and trans-fatty acids. Functions: High-density energy storage (

Includes triglycerides (saturated, monounsaturated, and polyunsaturated fatty acids), phospholipids, and sterols (such as cholesterol). human nutrition lecture notes jimma university pdf

Clinical signs : Bilateral pitting edema, "moon face", thin/reddish hair, flaky skin dermatitis, enlarged fatty liver, and apathy.

: Indicates wasting; reflects acute, recent nutritional deficits. : Dissolves in water to form a viscous

Human nutrition is a cornerstone of global public health, clinical medicine, and socio-economic development. In developing regions, understanding the precise mechanisms of nutrient metabolism and dietary requirements is vital for combating the dual burden of malnutrition.

Carbohydrates are the primary source of metabolic energy. They are organic compounds composed of carbon, hydrogen, and oxygen. : Monosaccharides : Glucose, fructose, galactose. Human nutrition is a cornerstone of global public

Optimal nutrition occurs when nutrient intake perfectly aligns with metabolic requirements, physical activity levels, and physiological states. Achieving this equilibrium prevents cellular oxidative stress, optimizes metabolic pathways, and fortifies immunological defenses against infectious pathogens.

The most concentrated energy source, yielding 9 kcal/g. Lipids are vital for cellular membrane structure, signaling molecules, and the absorption of fat-soluble vitamins. Essential fatty acids, such as linoleic and alpha-linolenic acids, must be obtained via diet. Micronutrients

: NAD and NADP coenzymes. Deficiency results in Pellagra , characterized by the 4 Ds: Dermatitis, Diarrhea, Dementia, and Death.

Characterized by severe wasting, loss of subcutaneous fat, muscle wasting ("old man face"), and extreme energy deficiency.
