What percentage of fat, protein, and carbohydrates is necessary for a balanced diet?
Asked by rindi on Jun 10, 2008 in Nutrition

In the last week, 30% of my diet was fat, 27% was protein, and 43% were carbohydrates. Is that healthy?


The Dietary Guidelines for Americans recommends this distribution of energy nutrients:

Fat: 20 - 35% of total calories (average 30%)
Protein: 10 – 35% (average 15%)
Carbohydrates: 45 – 65% (average 55%)

Some healthy diets, like the Mediterranean Diet, promote 40% of calories from fat, as long as it's from healthy olive oil, while saturated fat from meat is low and fiber from beans, grains and vegetables is high.  Your diet might meet those criteria if your fiber intake is at least 25 grams a day and your saturated fat is less than 10% of total calories.
