What is Fructose
Fructose s a common sugar. It is a monosaccharide. Fructose is extracted from a number of different fruits.
It makes up around 50% of table sugar (also known as inverted sugar). As well as this, it is the component part of many other sugars.
How is the Glycaemic Index of a Sugar Relevant to Keto?
The Glycemic Index (GI) is a way of rating carbohydrates. All sugars are carbohydrates.
The GI is rated from 0-100. In simple terms, it measures how quickly a food will affect your blood sugar(glucose) levels when you eat that food, or in the case of sugars, normally a food that contains the sugar.
If you have been living a keto diet for any time, you will likely know that one of the main aims is to maintain static blood sugar levels.
It is the spiking up of blood sugar levels that leads to that euphoric feeling, followed by a feeling of hunger, which makes you want to eat more.
It is by controlling these blood sugar levels which prevents cravings for further sugary foods.
If you have diabetes or know somebody who has, they are probably very conscious of the GI value of a food as they will use this rating to help control their blood sugar levels.
Foods scoring zero, or as close to zero as possible, will not spike your blood sugar levels. These foods are broken down more slowly. Foods that are closer to the higher end of the GI are broken down quickly in the body causing a rapid increase in blood glucose levels. This is also known as a ‘sugar rush’. Once this ‘rush’ has peaked, we then start to feel rubbish in ourselves and crave another ‘rush’ to make us feel good again.
It is for this reason that sugars are limited on the keto diet, if not your blood sugar levels would constantly be yo-yo-ing.
This is not health for anybody. More importantly, it will make it very difficult for your body to remain in a state of ketosis.
In this article, we will take you through which sugars to avoid and which ones are safe to consume.
