The beta-carotene, an antioxidant that colors several fruits, would protect against the decline of the cognitive faculties (memory and intellectual vivacity) partner to the ageing. His/her/its action would not appear while long-term.
These results come from a vast test led by researchers of the Harvard university by a cohort of 6 000 men, followed on one period varying of three years to about twenty years.
The topics that had absorbed a supplement of 50 mg of beta-carotene every other day, during at least 15 years, got the best results to the cognitive tests. The effects of the beta-carotene – that changes in vitamin HAS in the organism – on the cognitive faculties would be modest, but meaningful long-term, indicate the results.
Since 40 years
The senile craziness is a trouble associated to the ageing that gets settled in a very progressive and subtle manner, explain the researchers. So well, that a reduction, even minimal, some cognitive decline can have a positive impact importing on the mental health at the end of about fifteen years. Since the beginning of about forty, one should consider increasing his/her/its contribution in beta-carotene in order to be able to take advantage of his/her/its protective effects against the decline of the cognitive faculties therefore, they estimate.
The scientists assign this protective effect to the action antioxidant of the beta-carotene, that would contribute to counter the phenomenon of the stress oxidative, which would be the main reason of the progressive decline of the cognitive faculties.
The effect of the beta-carotene would be similar to the one of it, a medicine of synthesis used to improve the cognitive functions of the patients affected by Alzheimer’s illness, make notice the authors of the survey.
It would be also applicable to study the effects of other substances, notably the fatty acids of type omega 3, on the long-term maintenance of the intellectual faculties at the aging people, concludes the researchers.
