Task

A man aged 20 has a body weight of 60 kg, a body height — 1.7 m. His meal includes: rice — 50g, steak — 170 g, white bread — 25 g, tea — 60g. How many calories does he get with proteins, fats, carbohydrates?

Solution (according to Table 4)

1. Amount of calories consumed:

a) 100 g rice — 230 kcal 50 g rice — X kcal X = (50 x 230): 100 = 115 kcal

b) 50 g steak — 370 kcal 170 g steak — X kcal X = (170 x 370): 50 = 1,258 kcal

c) 100 g white bread — 220 kcal 25 g white bread — X kcal

X = (25 x 220): 100 = 55 kcal

d) 100 g tea — 99 kcal 60 g tea — X kcal X = (69 x 99): 100 = 68 kcal

e) Amount of calories: 115 + 1258 + 55 + 68 = 1,496

2. Proteins consumed:

a) 100 g rice — 8 g proteins 50 g rice — X g proteins X = (50 x 8): 100 = 4 g proteins

b) 50 g steak — 19 g proteins 170 g steak — X g proteins

X = (170 x 19): 50 = 64 g proteins

c) 100 g white bread — 7.6 g proteins 25 g white bread — X g proteins

X = (25 x 7,6): 100 = 1.9 g proteins

d) 100 g tea — 2 g proteins 60 g tea — X g proteins X = (69 x 2): 100 = 1.4 g proteins

e) Amount of proteins: 4 g + 64 g + 1.9 g + 1.4 g = 71.3 g

3. Fats consumed:

a) 100 g rice — 5 g fats 50 g rice — X g fats X = (50 x 5): 100 = 42.5 g fats

b) 50 g steak — 21 g fats 170 g steak — X g fats X = (170 x 21): 50 = 71 g fats

c) 100 g white bread — 0.9 g fats 25 g white bread — X g fats

X = (25 x 0.9): 100 = 0.2 g fats

d) 100 g tea — 0 g fats 60 g tea — X g proteins X = (69 x 0): 100 = 0 g fats

e) Amount of fats: 42.5 g + 71 g + 0.2 g = 113.7 g

4. Carbohydrates consumed:

a) 100 g rice — 29 g carbohydrates 50 g rice — X g carbohydrates

X = (50 x 29): 100 = 14.5 g carbohydrates

b) 50 g steak — 18 g carbohydrates 170 g steak — X g carbohydrates

X = (170 x 18): 50 = 61.2 g carbohydrates

c) 100 g white bread — 50 g carbohydrates 25 g white bread — X g carbohydrates

X = (25 x 50): 100 = 12.5 g carbohydrates

d) 100 g tea — 8.5 g carbohydrates 60 g tea — X g carbohydrates

X = (69 x 8.5): 100 = 5.8 g carbohydrates

e) Amount of carbohydrates: 14.5 g + 61.2 g + 12.5 g + 5.8 g = 94 g

The answer: The food contains: calories — 1496, proteins — 71.3 g, fats — 113.7 g, carbohydrates 94 g.

5. Conclusion (variants)

· A daily energy consumption exceeds (corresponds to, is lower than) caloric content of nutrition per day, therefore it is necessary to increase (maintain, decrease) the caloric content of nutrition by ______ Kcal.

· The ratio of proteins, fats, carbohydrates in nutrition makes up __________, but 1:1:4 ratio is required; so it should be increased (decreased) (to specify by what nutrients).

· The regimen of nutrition meets (does not meet) the demands of a balanced diet (to specify the available malnutrition), therefore it is necessary ___________ (references, recommendations for change of a nutrition regimen are given). For correction of nutrition it is necessary to ____________ (to specify the necessary changes in nutrition).
