The body does not require any added sugar to stay healthy. Hunters/gatherers and our ancestors consumed fruits and milk that are natural sugar to obtain energy.
<h3>What is the difference between added sugar and natural sugar?</h3>
- Natural sugars are found in unprocessed food such as fruits and milk.
- Fruits contain fructose and milk contains lactose.
- On the other hand, added sugars are the artificial sweeteners that we often add to our daily diet in the form of white sugars and caloric sweeteners.
- From the perspective of health, it is always better to opt for natural sugar that keeps our body stable energy and stable metabolism.
- Added sugars are harmful when consumed in higher quantities.
