Study Notes
Carbohydrate Consumption Patterns
- In industrialized nations, people tend to eat more highly refined starches and added sugars, whereas in developing nations, diets are largely based on unprocessed carbohydrates, such as whole grains, beans, potatoes, and starchy vegetables.
- Nutritionally adequate diets should provide 45-65% of total energy from carbohydrates.
- The typical diet of adult Americans supplies about 46% of calories from carbohydrates, with a significant portion coming from added sugars.
Added Sugars in American Diets
- Added sugars are sources of empty calories, with the average American consuming about 22 teaspoons (almost 18% of daily energy) per day, exceeding the recommended daily limit of 12 teaspoons (200 kcal) for a 2000 kcal diet.
- A 12-ounce can of cola-flavored soft drink contains about 37g of added sugar, contributing to 150 kcal of added sugars (three-quarters of the daily limit).
- Main sources of added sugars in Americans' diets include sugar-sweetened beverages, snacks, and "sweets".
Reducing Added Sugar Consumption
- Practical ways to reduce added sugar consumption include:
- Replacing soft drinks with plain water or infused water
- Making carbonated drinks with 100% fruit juice and club soda
- Reading labels for juice content and avoiding "fruit drinks" with added sugars
- Preparing portable, nutritious snacks, such as fresh fruit and vegetables, to replace processed snacks
- Choosing whole, unprocessed foods, like fruits, over processed snacks, like pastries or chips
