    Im having problems understanding the details of why some food have higher effect on bloodsugar than others. For instance, why does diffent types of bread, have diffrent effect on bloodconcentration?

    What happends if you like combine foods like fruit and cheese?

    I would love a detailed explanation of this.

    If like a person eats cake or oatmeal his blodconcentration increases rapidly unlike someone who eats fibers. Why is that?

    i think its related with the food glycemix index. the highe the GI, the quicker it will affect blood sugar. The food with lower GI will release sugar to the blood slowly. U can try to search more about it.

    This is not my area but it's to do with how the carbohydrates in food are broken down. "Blood sugar" is the concentration of glucose in the blood, most of the food you eat does not contain glucose but more complex carbohydrates that are broken down into glucose. The effect of different foods on blood sugar will depend on how much and what type of carbohydrate they contain and the rate and efficiency of the conversion of these carbohydrates into glucose.

    Cake has sugar and processed wheat flour which is carbohydrate that can be rapidly digested. I've never heart that about oatmeal. Oatmeal has lots of fiber, and fiber slows down the digestion of the carbohydrates, so I don't think it is comparable to cake.

    Depends on how it's processed. Quick oats are digested quicker so have a higher GI.

    Most important factor is fibre content. Wholemeal bread, for example, has a lot more fibre than white bread. Since both have about the same amount of starch, the amount of sugar released after digestion is about the same. But with the fibre, the digestion is slower, and the sugar is released more slowly, meaning less of a spike in blood concentration.

    If you mix a food with lots of sugar with another food with lots of fibre, it will slow the release of sugar into your blood.

    Wholemeal is not as good as whole grain. Though I'm a bit perplexed by the numbers on this chart Glycemic index and glycemic load for 100+ foods - Harvard Health Publications

    Seems to be a mixture of general descriptions and specific manufacturers' products.

    This person doesn't give numbers, but she says you need to distinguish wholemeal, wholegrain and multigrain. She also recommends white sourdough bread. Best Breads for Lunchboxes | Dr Joanna Read the labels, especially the nutrition/ ingredients panel.
