physician now investigated the effects of various forms of nutrition and diet on cognitive health, to find out whether a special diet can protect against the development of dementia.

In their current study,

the scientists of at Columbia University found that proper nutrition prior to the development of dementia appears to protect. The experts published the results of their study in the English-language journal “Neurology”.

protect against cognitive loss which forms the diet?

the study included about 2,600 male and female volunteers aged from 25 to 45 years. The diet of the participants was evaluated at three times by repeated questionnaires was determined on the basis of those then the average food intake for each individual. For example, the effects of the Mediterranean diet and the so-called DASH diet were examined. If people kept on these two dietary patterns, the subjects at the age of 55 had improved cognitive health. One reason seems to be that these forms of the diet contain much polyunsaturated fats, pulses, protein, dietary fibre and micro-nutrients like thiamine, folic acid, magnesium, zinc, iron, and potassium researchers according to.

what is included in our typical diet?

the typical Western diet is often rich in trans-fats, saturated fats, highly processed foods and refined sugar and salt. In contrast to this is the nutrition in the Mediterranean-style rich in whole grains, nuts, fruits, vegetables and olive oil, and low in processed meat, red meat, trans or saturated fats and refined sugar.

Mediterranean diet improves the endurance

that Mediterranean diet seems to improve health and to protect against cardiovascular diseases. In another small study of St. Louis University showed subjects who took a Mediterranean diet to, improved endurance performance in comparison to a conventional Western diet. Participants ran in the investigation of five kilometres on a treadmill, even after four days of Mediterranean diet and once again after four days with a typical Western diet. After four days of the Mediterranean diet accelerated the movement speed of the subjects by six percent, although the heart rate in two rounds was comparable. The reason for this difference can be, that a Mediterranean diet is alkaline, has anti-inflammatory properties, contains nitrates, and is rich in antioxidants. The benefits of a Mediterranean diet were however quickly lost when subjects switched their diet back on a typical Western diet. According to the researchers, this underlines the importance of a long-term adherence to the Mediterranean diet.

what is the MIND diet?

another study examined the eating habits of the Australians. It became evident that a special diet is associated with a reduction in the risk for cognitive decline in later life. The so-called MIND-diet was developed by Professor Martha Morris in the United States. This form of nutrition refers not only to the Mediterranean diet plan, but also a list of foods, of which it is already known that they promote the health of the brain such as antioxidant-looking berries and green leafy vegetables. The study examined whether 1,220 Australian adults from the age of 60 years developed a cognitive impairment over a period of twelve years. At the beginning of the study, the scientists surveyed the participating to their diet. Subjects in the study were either on the Mediterranean diet or the mind diet. The subjects who took to himself, the MIND diet lowered the risk for cognitive decline or dementia by almost a fifth. The other group of subjects who took a traditional Mediterranean diet with him, showed no such benefit. (as)
