High levels of vitamin C , which is important for male fertility, as well as the richness of magnesium - an important component for testosterone production, make raspberries one of the most recommended foods to help conceive.
The powerful antioxidant abilities, which are mainly due to the huge amounts of vitamin C in raspberries, protect sperm from oxidative stress. This year's study by the American laboratory Lawrence Berkeley focused on a group of sexually mature men and found that men with the highest intake of vitamin C have 20% less DNA damage to their sperm than those with normal intake of vitamin C.
In women, higher concentrations of the antioxidant significantly reduce the risk of miscarriage.
But their usefulness is not limited to the field of fertility. According to Dr. Wilson, a leading expert in nutrition and reproductive medicine, a handful of raspberries offer more vitamin C than 173 grapes, and while not a "superfood," raspberries have an incredible vitamin richness combined with a unique glycemic index: the lowest among all known fruits. The glycemic index (GI) reflects the rate at which carbohydrate-rich foods affect the secretion of insulin from the pancreatic islets of Langerhans and the corresponding levels of insulin in the blood after a meal. In modern dietetics, the consumption of foods with a low glycemic index is a key element of a successful diet.
This means that the sugar from the fruit is absorbed slowly and gradually by the body, without accumulating as excess fat. Combined with its high fiber content , raspberries become a food suitable for controlling hunger, satisfying only a few calories.
Compared to the Indicative Daily Intake (RDA), 120 g of raspberries contain: vitamin C - 53.7% of RDA; manganese - 41%; fiber - 31.9%; vitamin K - 11.9%; omega-3 fatty acids - 6.2%; honey - 5.5%; calories - 3% or only 63 calories per cup of raspberries.
