Let me break it down for you:
Total energy supply for IND/BD/PAK = 2459/2450/2440 kcal per person per day
A protein provides 4kcal/gram as does a carbohydrate.
A fat provides 9 kcal/gram.
Taking the protein supply (protein quality is variable but lets just stick to the raw energy provided) of the three countries: IND = 59 grams BD = 55 grams PAK = 64 grams
That means 236 kCal, 220 kCal and 256 kCal respectively of energy supply from protein.
That is 9.6%, 9% and 10.5% of the total energy supply for each country.
Now the remaining non-starch/carb is obviously made up by the fat intake.
Thus for India, it would be 41% - 9.6% = 31.4% from fat intake
For BD it would be 20% - 9% = 11% from fat intake
For Pakistan it would be 50% - 10.5% = 39.5% from fat intake.
So by energy breakdown of carb/protein/fat for each country:
IND = 59/10/31
BD = 80/9/11
PAK = 50/10.5/39.5
According to 2010 Dietary guidelines for USA:
http://blog.myfitnesspal.com/ask-th...rb-protein-and-fat-breakdown-for-weight-loss/
The 2010 Dietary Guidelines for Americans recommends eating within the following ranges:
- Carbohydrates: 45-65% of calories
- Fat: 20-35% of calories
- Protein: 10-35% of calories
Now you compare these intake profiles with that....tell me which of the three is doing worst? All 3 can definitely increase their protein intake somewhat for sure....but only one is heavily dependent on carbs for energy (and thus low diet diversity score).
The problem regarding BD is not so much the fat being half of the recommended minimum, but your protein quality being pretty abysmal according to the food security index....and your carb intake is 80% of your calories (well above 65% max recommended).
Why do you think all those BD immigrants are having 3 times the diabetes rate of the regular population? Its all the eating of rice. Ideally protein is the best substitution, but even transferring say 20% of energy intake to healthy fats from rice carbs would be much better.
