• The Institute of Medicine of the National Academies published dietary reference intakes for energy, carbohydrate, fiber, fat, fatty acids, cholesterol, protein, and amino acids in 2002.
• The Food and Nutrition Board of the United States Institute of Medicine identifies Acceptable Macronutrient Distribution Ranges (AMDR) for adults as 45–65% carbohydrate, 10–35% protein, and 20–35% fat as a percentage of total energy, which are associated with reduced risk of chronic diseases while providing adequate nutrients.
• The anterior pituitary produces growth hormone, a protein that influences metabolic activity by causing the body to store carbohydrates, synthesize proteins for growth, and use fat for energy.
• In 2006, the typical American diet consisted of approximately 2,200 kilocalories (9,200 kJ) per day, with 50% of calories from carbohydrates, 15% from protein, and 35% from fat.
• Carbohydrates spare protein more efficiently than fat under conditions of marginal calorie, protein, or glucose intake, making plant foods a more efficient substitute for fatty animals despite the higher processing requirements (Speth and Spielmann 1983).
• Nitrogen isotope data from bulk collagen samples underestimates the significance of plant foods in Neanderthal diets because it only provides evidence for protein consumption, leading to an undercalculation of carbohydrate and fat intake from plants.
• The nutritive content per 100g fresh weight of Ocimum basilicum Linn. includes 28.84g carbohydrate, 0.64g fat, 3.15g protein, and 92.06g water.
• The macronutrient ratio of the traditional Inuit diet was approximately 56% protein, 43% fat, and 1% carbohydrate, indicating that pre-contact Inuit people were in ketosis due to very low carbohydrate intake.
• The leaves of Vernonia amygdalina contain varying concentrations of protein, moisture, carbohydrates, ash, fat, minerals, oils, and vitamins.
• The authors suggest that Inuit and other indigenous diets, which are characterized by lower levels of carbohydrate and higher levels of fat, contain wisdom that could be realized to improve health outcomes.
• During exercise, the human endocrine system releases hormones that mobilize stored energy from fat and carbohydrates.
