The absorption of carbohydrates via the intestinal epithelium is achieved by transport proteins. Glucose is transported by a sodium-dependent glucose transporter 1 (SGLT1). This protein becomes saturated with a high glucose intake of approximately 60g per hour. GLUT5 is another transporter that transports fructose. If both transporters are used simultaneously, it is possible to absorb…
Carbohydrate intake during exercise can enhance endurance exercise performance. The recommendation is to consume 30-60 g/h carbohydrate for events lasting 1 – 2.5 h and for events over 2.5 h up to 90 g/h. If more than 60g/h is ingested it is important to realise that the type of carbohydrate that is ingested is critically…
In the last three years we helped a lot of triathletes with their optimal nutrition strategy towards half distance and full distance ironman triathlons. In the spring of 2017 we introduced the NutrID Kerosine (ratio 2:1, ratio 3:2 and ratio 1:1). The three different ratios stand for three different carbohydrate intakes per hour. Ratio 2:1…
