Calorie Intake
Calorie Intake
Calorie Intake
Calorie intake varies worldwide due to differences in wealth, food supply, diet, climate, and population, affecting global food demand and supply.


Understanding calorie intake
Understanding calorie intake
- Calorie intake measures the energy people get from food daily.
- Calorie intake reveals nutritional patterns.
- Average calorie needs depend on age, gender, and activity levels.
- Global calorie supply affects health and development across countries.


Global variations
Global variations
- High-income countries have average calorie intakes above 3,000 per person per day.
- Low-income countries often have calorie intakes below 2,200 daily.
- Regions like North America and Europe show higher calorie consumption.
- North America and Europe have higher consumption of meat, processed grains with added sugars, and saturated fats.
- Parts of Africa and South Asia have lower calorie intakes due to limited food availability.


Economic factors
Economic factors
- Wealthier countries afford diverse, abundant food, leading to higher calorie intake.
- Poorer countries face food insecurity, reducing average calorie intake.
- Economic growth can increase calorie intake by improving food access and diets.
