Study Notes
Nutrient Classes and Energy Sources
- Alcohol is not classified as a nutrient.
- Fats provide the highest energy yield, delivering 9 kilocalories per gram.
Digestion and Muscle Control
- Sphincters are ring-like muscles preventing the backflow of partially digested food in the gastrointestinal tract.
Dietary Principles
- Moderation in a diet involves paying attention to portion size to avoid excessive calorie intake.
- Recommended carbohydrate intake for Americans is 45-65% of total calories.
Carbohydrates and Fiber
- Fiber consists of polysaccharides that are indigestible by human enzymes and cannot be absorbed.
- The three main disaccharides in foods are maltose, sucrose, and lactose.
- Dietary fiber consists of substances in plant foods that remain undigested.
Nutritional Recommendations and Values
- Daily Value reflects the percentage of RDA met by a specific serving of food.
- A balanced diet should balance caloric intake with calories burned daily.
- RDAs are set to meet the needs of nearly all healthy individuals.
Enzymes, Energy, and Food Sources
- The primary enzyme for carbohydrate digestion is pancreatic amylase.
- Carbohydrates are utilized by the body for energy, preserving protein, and preventing ketosis.
- In the American diet, most calories from fat come from animal sources.
Nutrient Densities and Toxicities
- Nutrient density is defined as the amount of nutrients relative to calorie content.
- Overconsumption of vitamins, minerals, or water can lead to toxicity.
Sites of Digestion and Physiological Responses
- The small intestine is the main site for digestion and nutrient absorption.
