Document Summary
Calorie: a unit that measures heat energy. Plants package calories into carbs, photosynthesis glucose molecule (energy stored in its carbon hydrogen bonds) Also found in lipids and proteins (+ carbs) Energy content in food is measured in calories calorie. Heat energy necessary to raise the temperature of 1g of water by 1 degree. Hear energy required to raise the temperature of. ** 1000 calories = 1 calorie = 1 kilocalorie. Glucose, protein and lipids store energy in their carbon-hydrogen bond. Per gram, lipids store more energy than glucose and protein greater abundance of carbon-hydrogen bonds. Carbs: 4 kilocalories per gram (need at least 50-100g per day) High fat foods have a weak effect on satiation (passive overconsumption), energy dense = more kcal per bite. Strong satiety signals once it enters the intestine. Protein = most satiating, decreases energy intake of the next meal. Can measure the energy liberated when proteins, carbs and lipids are burned separately.
