Cancer experts clarify "superfoods"
"Superfoods" are supposed to make them thin, efficient, fit and, above all, healthy. It is sometimes said that these exotic plants stop the aging process, strengthen the heart and even protect against cancer. The health experts explain what is really wrong with the claims. In addition, they refer to local foods, which can also be called "superfoods".
Are "superfoods" really so good?
They should help you lose weight, keep the body young, strengthen the immune system, prevent disease or even heal: we talk about "superfoods". The sale of exotic plants such as chia seeds, acai berries and goji now makes millions of sales. But are these foods really so good? The Cancer Information Service of the Deutsches Krebsforschungszentrum (DKFZ) has published a recent communication explaining this phenomenon.
Certified positive features
According to experts, there are indeed experimental studies that certify the nutritional properties of certain positive properties of Superfoods. Nevertheless, many scientists are critical.
After all, the studies were done only on cells or animals and usually focused only on individual active substances, but not on the diet as a whole.
As the cancer information service explains, the term superfood is an invention of marketing services and suggests a very high quality for the consumer.
The term is neither legally protected nor precisely defined – each product can be called superfood. Another reason to be suspicious.
"Individual foods that feed on" superfoods ", such as exotic fruits, can contribute to a varied diet." Susanne Weg-Remers, Director of the Cancer Information Service of the German Cancer Research Center.
"The fact that they can protect themselves against diseases such as cancer has no scientific basis," says the expert.
The Cancer Information Service has a comprehensive database containing all the scientific information on cancer, prevention, early detection and treatment.
"We would know if there were any significant study results," says Weg-Remers.
Native plants with high nutrient and active substance content
Some native plants also have a high nutrient and active content and can therefore be called superfoods.
Local alternatives include kale, beets, native berries or carrots, onions and apples, all of which provide nutrients that are good for your health.
For example, whole grains and flaxseeds provide enough fiber.
The advantage of these foods at the door: they are usually cheaper and their origin is traceable.
Superfood products, on the other hand, often come from abroad, are expensive and are distributed via the Internet.
Conclusion of the European Food Information Center (EUFIC): instead of relying on a handful of exotic foods in terms of nutrition, so-called "excellent", it is better to put on the table the whole range of local fruits and vegetables.
Protection against serious diseases
To protect against cancer and other chronic diseases such as diabetes and heart disease, it is recommended, according to experts, to follow a diet mainly composed of plants.
As stated by the Cancer Information Service, the European Code Against Cancer gives the following recommendations:
- At least 400 grams of fruits, vegetables and legumes per day
- Whole grain cereals daily, if possible
- Avoid foods high in sugar and fat
- If possible no sweet drinks
- Less than 500 grams of meat a week. If possible no processed meat
- Avoid prepared dishes
- Maximum of six grams of salt per day. (Ad)
