Superfoods: the real overview

Superfood is a marketing term used to describe foods with presumed health benefits. The news and the opponents of the supplements – here is the antagonist – the food with almost magical properties, which is capable of forcing the additives into the trash.
Is it true? Are there superfoods?
Superfoods = superpowers+ not so great dangers
Superfoods are defined as foods that are considered healthy and may even sometimes affect certain medical conditions. In addition, they often have an abnormal content or concentration of certain nutrients or excipients.
So-called superfoods, can have an unusually high content of antioxidants, vitamins and other nutrients. However, the definition excludes, for example, conventional herbs. Probably because of the expectation that superfoods will still have a nutritional potential.
For the first time, the term was put into use by Aaron Moss in Nature Nutrition in August 1998. However, since 1 July 2007, the EU has been in force for a ban to designate food as "superfood" in an official label or mark if this does not apply to the medical examination.
The reason: a powerful marketing attack on conventional foods to which a consumer misleading label attaches.
We can develop a functional definition: superfood is a food that brings health benefits and is able to displace nutritional supplements.
Many organizations have turned to the problem of superfoods. Cancer Research UK publicly notes that superfoods are often advertised as having the ability to prevent or cure diseases, including cancer.
These are not realistic expectations, just the sick exploit the "straw hope", and supermarket sellers - the hope of the sick. Though unhappy with public opinion, the institute gives the adequate conclusion that excessive belief in superfoods begins to shift the balanced diet and worsen the health of patients.
Research is also controversial. For example, for cocoa, opinions are sharply polarized - the first research suggests that cocoa has a positive effect on blood pressure, but subsequent research completely disputes such a link. In addition, marketing is very often far from the proclaimed truth.
Some foods actually contain specific substances such as epicatechin gallate in green tea, helping to lose weight, pectin in apples and a number of others.
That is, the particular functions of certain foods are a fact that can not be denied, but we must not forget that there is no absolute and ultimate truth in eating, and even the best food at one time can be it is a burdening body or depriving it of something important in the long run.
Still, what are these superheroes in the food world?
Here are few of the so-called superfoods:
1. Eggs - Each egg has about 6 grams of protein but only 72 calories. Ideal for your diet.
2. Tomato sauce - Contains lycopene that strengthens the skin, vessels and heart.
3. Dried plums - polyphenols, plant chemicals that stimulate bone density by stimulating bone-forming cells.
4. Nuts - alpha-linolenic acid, omega-3 fats that are dietary and healthy ..
5. Brussels sprouts (and cauliflower) - has more glucosinolates than any other vegetable, and acts as an antioxidant. It is also dietary and can be deliciously prepared. However, broccoli germs are the strongest of these.
