Fat, protein and carbohydrate are the three nutrients that provide
energy. Alcohol also provides energy. There is some evidence to
suggest that a poor energy mix of the diet is a risk factor in
various diseases such as coronary heart disease and certain cancers.
The COMA panel reviewed this evidence and concluded that it would
be useful to set DRVs[414]
for total fat (fatty acids and glycerol), fatty acids, sugars
and starches (Table 3)Suggested

Carbohydrates have not been included in Guideline Daily Amounts
because these were thought to be less important than other categories
for which GDAs were given, and potentially misleading. Back
