Carbohydrate tolerance and food frequency

Carbohydrate tolerance and food frequency.

Dietary and pharmacological approaches to slowing the rate of glucose absorption and blunting the insulin response show promise in the treatment of diabetes and hyperlipidaemia. These approaches include dietary fibre, low-glycaemic-index foods and gastrointestinal digestive enzyme inhibitors. One common feature is that they spread the nutrient load over time. A potentially simpler approach is t...

Food Structure and Carbohydrate Digestibility

Food Carbohydrate Chemistry

The reactions of sugars that are critical in food science applications can be organized into a few general types of reactions that are heavily influenced by pH. Although there are a few exceptions, most of these reactions occur under the relatively mild conditions that prevail during processing and storage. This chapter will not address reactions of chemical synthesis and sugar structure proof....

The Effect of Chloroform and Phosphorus Poisoning on Carbohydrate Tolerance

In a previous communication (1) we reported the results of a study of the tolerance of normal dogs for glucose, fructose, and galactose. It was pointed out that fructose is less effective and galactose more effective than glucose in producing alimentary hyperglycemia. Dogs show relatively slight variations in their tolerance for fructose. Judging from a number of similar experiments on normal h...

The food frequency questionnaire.

To the Editors: Of course we agree with Kristal et al. (1) that validity is an issue of degree rather than a dichotomy and that multiple methods will usually be useful when evaluating validity because a perfect standard is rarely available. However, their examples based on face validity, construct validity, and predictive validity do not provide evidence that food frequency questionnaires shoul...
