12(b). Now discuss another health advantage of a vegan diet. Again, discuss the connection between the health benefit and specific nutrients in the diet. Include at least 2 sentences in your discussion of this health advantage. Include a reference..

Answer 1

question 1

1585.5 kilocalories per day

question 2

(a) equation and calculations

(b) unit of measure

Weight = 125 pounds = 56.6 kg

Height = 5'5" = 165 cm

Age = 23 years

Basal Metabolic Rate = 10 * weight (kg) + 6.25 * height (cm) – 5 * age (y) + s

= 10 * 56.6 + 6.25 * 165 - 5 * 23 -161 (s= -161 for females)

= 1321.25

Total calories needs = BMR * 1.2

1.2 = appropriate activity factor for a sedentary life

= 1321. 25 * 1.2

= 1585.5 kilocalories per day

(c) rationale for physical activity

Physical activity factor 1.2 is for little or no exercise. It was chosen as Amanda doesn't perform any exercises.

Answer 2

discuss another health advantage of a vegan diet. Again, discuss the connection between the health benefit and specific nutrients in the diet. Include at least 2 sentences in your discussion of this health advantage. Include a reference..
