True/False (Part 7)

Is it true that excess sugar is transformed into fat?

TRUE… This is due to the fact that such excess promotes the production of insulin which causes glucose being stored inside the cells. Therefore, and especially in the case of sedentary people, i.e. those who don’t have enough physical activity which helps eliminate this excess, sugar stocks pass into the cells where they are stored as fat. It is for this fundamental reason that we always recommend eating less fat and less sugar and having a regular physical activity.

Is it true that tuna and sardines contain the same amount of calories?

FALSE… Before answering, it is good to note that either the sardine or the tuna are, both, good for our health. Also, let’s not forget that we should always diversify foods so that we take full advantage of them. From the caloric point of view, these two types of food do not have the same values. In fact, and according to the Répertoire général des aliments (CIQUAL), 100 g of sardines contain 215 calories while 100 g of tuna contain 117 calories (thus, almost half the amount). These values, of course, may vary slightly depending on the brand.

Can we say that jam preserves the vitamin C present in the fruit?

FALSE… Indeed, vitamin C is water-soluble. Since it is fragile to heat, it will be largely destroyed during the jam cooking process. Moreover, this vitamin has an important antioxidant role which protects our cells against damages caused by free radicals. This vitamin helps as well in the proper functioning of the immune system and plays a role in wound healing and in the absorption of iron contained in vegetables.

Is it true that dietary fibres are classified under 3 types?

FALSE… Indeed, let’s state that dietary fibres are carbohydrates that can be found in vegetables. They are indigestible and for this reason their caloric level is low. Furthermore, these fibers are subdivided into two groups: soluble fibres and insoluble fibres. Soluble fibres (pectin, gums, oligosaccharides) are found in fruits and vegetables and have the ability to absorb a large amount of water, thereby forming a gel that mixes with the food bolus which leads to delaying its passage through the intestine. Thus, these fibers are important in the prevention of overweight, type 2 diabetes and excess cholesterol. As for the insoluble fibres (cellulose, lignin), they are found in cereals and leafy vegetables (ex, spinach). These fibers promote satiety and have a laxative effect. As such, they play an important role in the prevention of constipation.
