Carb pairing is a type of food combining diet.
Food combining refers to a way of eating in which certain types of foods are not eaten together. Proponents of food-combining diets believe improper combinations lead to disease and digestive distress.
So far, only one study has examined the principles of food combining. It tested whether a diet based on food combining had an effect on weight loss.
there is no evidence to support most of the supposedly scientific principles of food combining.

Many of the original food-combining diets were developed more than 100 years ago, when much less was known about human nutrition and digestion.
But what is now known about basic biochemistry and nutritional science directly contradicts most of the principles of food combining.
The principles of food combining diets are not backed by science, but that doesn't mean that the way you combine foods is always irrelevant. Vit C improves the absorption of non-heme iron (Iron from plant sources) for example.
