Green leafy vegetables, among others such as spinach and kale are the favorites chosen in particular by people who care about their health. As it turns out, eating them can also affect better behavior of cognitive functions.
A study at the University of Illinois proved the positive relationship between eating foods rich in lutein – spinach, kale, avocado or eggs, and nerve connections.
The analysis included 60 people aged between 25 and 45. Participants who were characterized by high intake of leafy vegetables showed a neuron response at a similar level as the younger group, not like their peers.
Thanks to the above observation, we have another, very important, reason to eat dishes rich in spinach or kale. They contain in addition to a large amount of vitamins, i.e., vit. C, vit. K, vit. E, fiber also compounds with anti-cancer activity and delaying the aging process, as well as improving memory and concentration.
During the aging process, people often experience a decline in both physical and mental activity. However, this process begins much earlier than we think. It becomes extremely important to make the society aware of how much can be achieved by introducing into your diet products whose consumption allows you to stay healthy.
No wonder that since ancient times outstanding personalities have been interested in how food affects health. For years, we have been trying to learn about the properties of various compounds found in specific products to ensure life in great shape. Therefore, it is important to eat the food at the right moment when the chosen substance can bring the most benefits, as in this case lutein.
Lutein is a nutrient that the body is unable to synthesise itself and must be delivered along with the diet. It accumulates in the tissues of the brain, but also the eye.
The experience of Khan and colleagues shows that lutein can play a protective role in the aging process, where the risk of senile dementia increases. In people with higher levels of lutein, neural connections responsible for cognitive functions were better involved.
This research focused on the participants’ attention. The next step in the analysis is also to assess the impact of lutein on science and memory.
Nevertheless, without waiting for further publications, you should boldly enjoy the benefits of nature. The vitamin and mineral bomb in green leafy vegetables will surely give us strength and vitality.
