Food gives us the nutrients we need to survive, and we know that a balanced diet helps with good health.
Furthermore, many people are looking for different foods as & # 39; medicines & # 39 ;, rely on eating some things that can be avoided or treat specific Conditions.
Certainly many foods contain & # 39; bioactive compounds & # 39; – chemicals that act on the body in ways that can promote good health. They are studied in the prevention of cancer, heart disease and other conditions.
But the idea of eating as a drug, though attractive, is easily oversold in the headlines, two researchers wrote in one piece for The Conversation. The stories are based on studies made in the lab, testing concentrated extracts from foods. The effect seen on real people eating the actual diet will be different from the effects on a petri dish.
If you do the maths, you'll really need to eat very large amounts of certain foods to get an active dose of the desired element. In some situations, your health may be at risk, rather than protect it.
These four foods, and a drink, show typical healing claims around the foods we eat are not always stacked.
Cinnamon, containing a compound called cinnamaldehyde, which is said to help lower weight and appetite
Cinnamon, containing a compound called cinnamaldehyde, is claimed to help weight loss and appetite control.
There is evidence of cinnamaldehyde reducing cholesterol in people with diabetes. But it is based on chemical analysis in large doses – not eating spice itself.
These studies give people between one and six grams of cinnamaldehyde per day.
Cinnamon is about eight per cent of cinnamaldehyde by weight – so you need to eat at least 13 grams of cinnamon, or almost half a supermarket jar, every day. More than you add to your morning soup.
Headlines on red wine health benefits are usually due to a chemical in grape skins called resveratrol
These are headline on red health benefits Wine is usually due to a chemical in grape skins called resveratrol. Resveratrol is a polyphenol, a family of chemicals with antioxidant properties.
It is said that resveratrol protects our cells from harm and reduces the risk of different conditions such as cancer, diabetes type, Alzheimer's disease, and heart disease. 19659002] There are some limited evidence that resveratrol has benefits to animal models, although studies made on people do not show the same effect.
It differs from wine, but about three micrograms (about three million a grams) of red wine contains resveratrol in each bottle.
Studies show that resveratrol benefits use at least 0.1 grams per day (which is 100,000 micrograms).
To get much resveratrol, you need to drink about 200 bottles of wine a day. We may probably all agree not to be too healthy.
Blueberries also contain compounds called anthocyanin Heart disease markers
Blueberries, such as red wine, are a source of resveratrol, but in some micrograms per berry you will need to eat more than 10,000 berries a day to get the active dose.
Blueberries also contain compounds called anthocyanins, which can improve some heart disease markers.
But to get an active dose there you are looking at 150-300 blueberries per day. [Obs] Angobromine, a chemical in chocolate is shown to reduce blood pressure at a dose of almost a gram of active compound, but not at a lower dose ” class=”blkBorder img-share” />
