Question 4 please

3. Table 4 below compares the compositions of human and bovine milk. Table 4 Nutrient (g/L) Human Cow Protein 11 35 Fat 45 37 Carbohydrate (lactose) - 68 49 Calculate the caloric value per litre of each kind of milk. Which one provides more energy per unit volume? (1 pt) Human Energy from Fat = 9 kcal/g 45*9 = 405 Carb = 4 kcal/g 68*4 = 272 Protein = 4 kcal/g 11*4 = 44 Total 721 kcal/L Cow 37*9 = 333 49*4 = 196 35*4 = 140 669 kcal/L Human milk provides more energy than cow milk 4. It is frequently recommended that a lactating woman should consume an extra 500 kcal/day, in addition to her normal diet. If she is producing 2 L/day of milk, what is her expected weight change per day? (refer to Table 4 above) (1 pt)

Answer 1

1 kg of weight = 7700 calories that is 7.7kcal.

Lactating women consume 500kcal / per day.

Amount of calories in 2L of milk = 721 $\times$ 2 = 1442 kcal.

Amount of calories in milk - Extra calories consumed = 1442-500

= 942 kcal.

Weight change is equal to 942/7700

= 0.12 kg

0.12kg of weight is lost everyday.
