nutWalnuts have twice higher level of the antioxidant polyphenols of all nut products and so help the body fight free radicals that damage cells and cause disease, according to research at the University of Pennsylvania.

Nuts such as almonds, peanuts, pistachios, hazelnuts and cashew nuts are also rich in unsaturated fatty acids, vitamins and protein, but scientists warn that the problem is that people do not eat enough such fruits.

“Our recommendation is that people should eat seven walnuts a day,” says study leader Joe Vinson.

Previous studies have shown that eating nuts reduces the signs of aging and protect against heart disease and some cancers. After it was discovered that only seven walnuts a day protects against heart disease, walnuts were immediately rated as super food.

Many nuts have long been considered the most perfect food in nature. It was found that of all the other nuts, walnuts contain the highest antioxidant levels. And when talking about food that is healthy for the heart, walnuts are among the top three healthiest foods.

Besides being rich in antioxidants, also contain healthy fiber, protein, vitamins and minerals. So it is no wonder that numerous studies have shown that regular intake of nuts can reduce the risk of heart disease, some cancers and diabetes type 2.

One of the interesting things is that walnut looks like a little brain, they even fight and twist just like the neo-cortex. Today we know that walnuts help development of more than thirty neuro-transmitters for brain function.

In the latest study, researchers from the University of Scranton in the US state of Pennsylvania analyzed the antioxidant content in several types of nuts: walnuts, almonds, peanuts, pistachios, hazelnuts, Brazil nuts, pecan nuts and cashew nuts.

Lead researcher Dr. Joe Vinson said: “Walnuts are ranked above peanuts, almonds, pecans, pistachios and other fruits. A handful of walnuts contains almost twice as much antioxidants than the same amount of any other nut fruit. Unfortunately, people do not eat a lot of nuts. Our research indicates that as part of a healthy diet should eat more walnuts. ”

A team of doctors Vinson was discovered that apart from the amount of antioxidants nuts and superior in strength of antioxidants they contain. Those which are found in nuts are 15 times more powerful than vitamin E, which has a reputation as a powerful antioxidant.

The researchers said that the best is to eat walnuts raw because precisely in this form are the most effective. But many people avoid nuts because they think they are fat and gaining weight. However, nuts are rich in healthy polyunsaturated and monounsaturated fats that do not clog blood vessels as well as saturated fats. If you eat nuts you will not gain weight, furthermore you could also lose weight because they cause a feeling of satiety.

“Seven walnuts a day is ideal amount in order to get the maximum benefit from them,” said Dr. Vinson.

Walnut kernel oil contains the most (55-65%), and high-value proteins (15%) and the same amount of carbohydrates and is also rich in potassium, magnesium, phosphorus, iron and vitamins B and C. List of walnuts contains fixed oil yellowish color, tannin, acid and bitter substances and bitter taste.

Since it contains decomposed medicinal ingredients, from the walnut leaves can be made syrup, extracts and similar preparations. The foliage is best to use while green and fresh.
