Nutritional Facts and Thermogenesis in Human Health
Key Nutritional Facts and Their Implications
Here’s a review of essential nutritional concepts and their impact on health:
- Food composition tables allow for the calculation of nutrient intake, which implies a certain amount of food. True
- Nutrients are involved in the prevention and development of pathologies. True
Thermogenesis and Its Role in Metabolism
Thermogenesis is the body’s ability to generate heat due to metabolic reactions. Heat dissipation balances this internal generation, resulting in thermal

Essential and Non-Essential Amino Acids
Essential Amino Acids: Isoleucine (Ile), Leucine (Leu), Valine (Val), Threonine (Thr), Methionine (Met), Cysteine (Cys), Tryptophan (Trp), Phenylalanine (Phe), Tyrosine (Tyr), Lysine (Lys), Arginine (Arg), Histidine (His).
Non-essential Amino Acids: Alanine (Ala), Asparagine (Asn), Aspartate (Asp), Glutamate (Glu), Glycine (Gly), Proline (Pro), Serine (Ser).
Ammonia Elimination
Organisms eliminate ammonia through different mechanisms:
- Ammonotelic: Excretion of
Carbohydrates: Fueling Your Body & Health Impacts
Carbohydrates: Fueling Your Body
The primary function of carbohydrates in the body is to provide energy. Fructose, galactose, and glucose are examples of monosaccharides, not polysaccharides.
Understanding Sweetness and Blood Sugar
The sweetness in a banana comes mostly from fructose and sucrose. A blood glucose level of 60 mg/dL is considered to be representative of hypoglycemia. In comparison with table sugar (sucrose), honey tastes sweeter because it contains fructose.
Dietary Choices and Carbohydrate
Baby Nutrition and Feeding Milestones (0-12 Months)
Alimentation from 0 to 14 Months
Breastfeeding (0-14 months):
- Provides the ideal amount of protein to meet the organism’s needs.
- Reduces the risk of allergies or intolerances.
- Fats promote healthy brain development, prevent high cholesterol, and protect against chronic conditions.
- Adequate amounts of mineral salts help avoid water retention and prevent anemia.
- The Q-factor improves the defenses of the digestive tract.
- Promotes close contact between mother and baby, affecting emotional and psychological
