The Claim
Replacing refined grains with whole grains to meet the 48 g/day recommendation does not increase total energy intake when total food volume is held constant.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When people replace refined grains with whole grains to meet the daily 48 gram recommendation, their total calorie intake does not increase if they eat the same amount of food by volume.
See the scientific wording
The economic modeling suggests that replacing refined grains with whole grains to meet the 48 g/day recommendation does not necessarily increase energy intake, as the substitution can be achieved without increasing total food volume or calories.
Whole grains contain more fiber than refined grains, so when you swap them without eating more food, the extra fiber takes up space in the stomach and intestines without adding calories. This means the same volume of food has fewer usable calories because fiber isn't digested and absorbed.
