Sugar includes two main types: added sugar and naturally occurring sugar. Sugar is often added to processed foods such as baked goods, desserts, breakfast cereals, condiments, salad dressings and marinades. In contrast, sugar occurs naturally in fruit, vegetables and milk.
Both natural and added sugars are ultimately broken down into fructose and glucose, which are metabolised the same once they reach your gut,
What does differ is how fast they’re broken down. Because the sugar in fruits is paired with fibre and water, it’s released much more slowly into your body, providing you with a consistent stream of energy, Added sugar, without fibre and water, is broken down immediately, leading to a surge in insulin and blood sugar levels. As a result, you don’t feel full at all - you just crave more sugar.
You should obviously eat plenty of fruit. But doing that means you will take in some sugar. The health benefits of the fruit are an acceptable trade off to me.
