100% nutrienti ..... 50% glucide ..... 30%proteine ..... 20%lipide
trebuie sa stim cate calorii elibereaza 1g proteina/ glucide / lipide
=>
1g de proteine = 4 kcal,
1g de glucide = 4 kcal,
1g de lipide = 9 kcal.
notam masa de glucide cu a , masa de proteine cu b si masa de lipide cu c
100% nutrienti ..... 50% glucide ..... 30%proteine ..... 20%lipide
m ............................. 4a ........................ 4b ....................... 9c
= 0,5m = 0,3m = 0,2m
4a + 4b + 9c = 1800
0,5m + 0,3m + 0,2m = 1800
=> m = 1800/1 = 1800 g
=> a = 0,5m/4 = 225 g glucide
b = 0,3m/4 = 135 g proteine
c = 0,2m/9 = 40 lipide
