Why do they add fructose to it? Only glucose would be more healthy and more appropriate for sports
Sports nutrition is not about health (at least not primarily), it's about maximizing energy intake. Using Maltodextrin/Glucose on one hand and fructose on the other you can utilize two different path of energy intake.
Here a bit more detailed explaination:
The key benefit comes from using different intestinal transport mechanisms:
- Glucose uses SGLT1 transporters, which can become saturated at around 60g/hour
- Fructose uses GLUT5 transporters, which can handle about 30g/hour
- By using both pathways simultaneously, you can absorb more total carbohydrates (up to ~90g/hour)
The typical optimal ratio is:
- 2:1 glucose:fructose ratio
- For example: 60g glucose + 30g fructose per hour
