How much dietary protein is needed?

Acceptable Macronutrient Distribution Range (AMDR)

• Developed by the Food and Nutrition Board of the
  Institute of Medicine
• Range of intakes for macronutrients expressed as
  a of total energy.
• Protein 10-35 depending on age
• Higher Protein diets 20-35 calories from protein

12
Recommended Dietary Allowance (RDA)

• The average daily dietary intake of a nutrient
  that would be sufficient to meet the needs of 97
  to 98 of healthy people.
• The RDA is intended to be used as a goal for
  daily intake.

Protein is 0.8 g/kg

Proteins Role in Optimal Health

• Build muscle
• Deliver oxygen to tissues
• Boost immunity
• Provide energy
• Aid satiety/fullness
• Help metabolize other nutrients
• Build better brains
• Manage weight

15
Protein Boosts Benefits of Exercise

• Exercise more effective when paired with
  moderately high-protein diet
• 2005 Journal of Nutrition
• Protein-rich diet lost more weight and almost
  100 of the weight was fat loss
• Maintenance of muscle mass attributed to leucine
  which works with insulin to promote muscle growth
• High-carb diet 25-30 was muscle loss

additive effects on body composition during
weight loss in adult women. Journal of Nutrition.

Outcomes for low carb, high protein diets

Why Maintain Lean Body Mass?

• Activities of daily living
• Weight maintenance via energy expenditure of
  muscle
• Survival from chronic illness such as cancer and
  cardiac events
• Bone health
• Muscle plays a central role in whole-body
  metabolism

Misunderstood Fat Profile

• More than half of beefs fatty acids are
  monounsaturated (good) fat the same
  heart-healthy fat found in salmon and olive oil
• 1/3 of beefs saturated fatty acid is stearic
  acid, a neutral saturated fat

A New Way to THINK about PROTEIN

• Deficiency
• Impaired growth and development
• Impaired brain function in children
• Depressed immune system
• Impaired gut mucosal function
• Adversely effect kidney function
