Explanation / Answer
Maria daily diet includes: 200g carbohydrate, 50g protein and 80g fat. Total= 330g.
To calculate percentage, we must divide each type of food between the total grams *100%
%car=(200/330)*100%= 60.61%.
%pro=(50/330)*100%= 15.15%
%fat=(80/330)*100%=24.24%
Between the options given there is not the answer, the nearest is option d.
The AMDR stablishes following ranges:
Carbohydrates: 45 - 65%
Protein: 15 - 25%
Fat: 20 - 35%
Knowing that, we can say that Maria intake is option a. Adequate carbohydrate, inadequate protein and high fat.
She follows an online article from a star, this testimonial is option a, an anecdotes because is not a fact, or is not support by a specialist.
