Hello.
We know that fructose is metabolized differently (in the liver without the involvement of insulin). So why is it generally recommended to consume fruit after finishing physical activity? Does fruit also contain other simple sugars?
Thank you for your response.
Fruit is also a source of sucrose. The recommendation to consume fruit after exertion is a topic for discussion - the advantage lies in the rapid initial satiation, satisfaction of sweet taste, providing fiber, carbohydrates, and micronutrients, thus initiating processes leading to the replenishment of depleted glycogen. Another perspective (opinion) suggests that the increased activity of insulin related to carbohydrate metabolism, which you supply immediately post-exertion, suppresses the production of growth hormone, which is (especially in strength sports) important for the regeneration of muscle tissue. The intake of fruit after exertion is, therefore, a matter of personal consideration based on the requirements for metabolism.
