Masterclass on Nutrition | Nutrition Expert

Explore the basics of nutrition, emphasizing health promotion through a balanced diet, the six essential nutrients, energy roles, and how malnutrition affects health.

Navigate the diet binge cycle: deprivation triggers cravings, leads to binge eating, and fuels guilt and repeated dieting. Distort hunger and satiety cues; yo-yo dieting harms health.

Discover how good food and key nutrients support life and health, and how a balanced diet provides energy, builds tissues, and regulates metabolic processes to promote health and disease prevention.

Explore carbohydrates as the body's main energy source, from simple sugars to complex starches, and their digestion, glycogen storage, fiber benefits, and glycemic index in a balanced diet.

Discover how carbohydrate foods from grains, legumes, vegetables, and fruit provide energy, compare simple and complex carbs, and explain how dietary fiber supports digestion and health.

Explore fats as essential nutrients and concentrated energy sources, covering saturated, unsaturated, trans fats, essential fatty acids, and their health implications and dietary sources.

Explore fats as essential nutrients that fuel and build the body. Learn about saturated and unsaturated fats, cholesterol, triglycerides, and their digestion via bile and pancreatic processes with lymphatic transport.

Explore how amino acids assemble into proteins, the body's protein balance, and how complete and incomplete proteins from animal and plant sources meet essential amino acid needs.

Discover how indispensable amino acids build tissues, differentiate complete proteins from incomplete ones, and compare animal, soy, and plant proteins, with vegan risks of protein imbalance and nutrient deficiencies.

Explore how digestion and absorption form a continuous process where mechanical and chemical breakdown enables nutrient absorption and metabolism, aided by enzymes, gastrointestinal secretions, liver, and pancreas.

Digestive processes break down nutrients, absorb them in the small intestine, transport them to cells, and fuel metabolism to ATP, with genetic diseases needing nutrient-specific diets.

Explore how energy balance dictates weight and health by examining energy intake, expenditure, and metabolism, including basal metabolic rate, energy density, and the roles of carbohydrates, fats, and proteins.

Explore how energy from food powers the energy system, measured in kilocalories, as metabolism converts nutrients into chemical, electrical, mechanical, and Tollman energy, using glycogen, fat, and muscle protein stores.

Explore how vitamins function as non-caloric micronutrients essential for metabolism, acting as coenzymes, antioxidants, and regulators of gene expression, with fat-soluble and water-soluble classifications and absorption differences.

Explore fat-soluble vitamins A, E, and D, detailing their functions, requirements, deficiency symptoms, safety risks, and food sources to support vision, immunity, bone health, and antioxidant protection.

Explore water-soluble vitamins, including vitamin C and B vitamins, their antioxidant roles, collagen synthesis, energy metabolism, deficiency risks, daily requirements, and food sources.

Explore phytochemicals' functions, including antioxidant activity, hormonal actions, enzyme interactions, and antibacterial effects, and learn how a colorful diet of fruits, vegetables, legumes, nuts, and whole grains supports antioxidant status.

Assess vitamin supplementation as dietary supplements taken by mouth in capsules, tablets, or liquids. Consider lifestyle, restricted diets, smoking, and alcohol; read labels and favor foods.

Explore fat-soluble and water-soluble vitamins, their coenzyme roles, and vitamin c as a reducing agent. Learn how plant phytochemicals link to lower chronic disease risk and why whole foods matter.

Explore how minerals perform diverse metabolic tasks, distinguish major and trace minerals, and explain absorption, transport, and dietary sources for health.

Explore trace minerals, their functions and requirements, deficiencies, toxicity, and food sources, including iron for hemoglobin and immune function, iodine for thyroid hormone, zinc, selenium, and more.

Explore how minerals, major and trace, are absorbed in the intestines and support tissue building, metabolic regulation, and neural signaling; a balanced diet often suffices over supplementation.

Explore how the body maintains water balance through intracellular and extracellular compartments, homeostasis, and regulated water intake and loss, including dehydration risks and kidney roles.

Learn how body water supports survival, transport, temperature regulation, and lubrication, with intracellular water around 40–45% of body weight and electrolytes plus albumin maintaining extracellular balance.
