In addition, with increasing amounts
of available carbohydrate in the food challenges, the calculated meal GI and GL values that were obtained on the basis of the published formula (21) were increased and were similar to the increased values in measured meal GI and GL values.
Consistent with these findings, it has been previously reported that the glycemic response rises with an increasing amount
of available carbohydrate after being challenged with a wide range of foods (43).
The tart green Granny Smith apples benefit the growth of friendly bacteria in the colon due to their high content of non-digestible compounds, including dietary fiber and polyphenols, and low
content of available carbohydrates.
If you continue longer aerobic exercise without a
lot of available carbohydrates, your body adapts by increasing its workforce of enzymes that metabolize fat (the muffin top and bat wings...) for energy.
In developing countries such as in Africa and parts of Asia, cereals can contribute as much as 70 per cent of energy intake, while in industrial countries, for example, the UK, they provide approximately 30 per cent of energy intake and 50 per
cent of available carbohydrates.
Glycemic load is based on the glycemic index, and is defined as the
grams of available carbohydrate in the food times the food's glycemic index and divided by 100.
Because we tend to de-emphasize grain intake in our WHFoods recipes and meal plans, and because we generally tend to emphasize intake of low glycemic index foods that have limited to moderate
amounts of available carbohydrates, we set a WHFoods recommendation level of 225 grams for total carbohydrate — about 10 % higher than the low end of the range recommended by the National Academy of Sciences (NAS) in its discussion of Dietary Reference Intakes.
Each contained 50 grams
of available carbohydrate.
For starters when food is chosen, it's consumed in whatever serving size that will provide 50 grams of carbohydrates (Note: Fiber is subtracted in order to get to 50 grams
of available carbohydrates).
Differences in testing methods include the use of different types of blood samples (capillary or venous), different experimental time periods, and different portions of foods (50 g of total rather than
of available carbohydrate).
