Doctors have discovered an ingredient used in the production of crisps and other popular snacks can make skin transparent.
The additive known as tartrazine is a common compound in the UK, which can be found in cereals and other foodstuffs, but only recently have researchers discovered its seemingly magical properties.
The discovery was made after a series of experiments conducted using chicken breasts that scientists were able to peer through when exposed to a certain type of light.
It is reported that this chemical – which can be washed off after application – would allow physicians and other professionals to look at a person’s veins without physically opening up the hand.
The Guardian reported that senior researcher Dr Guosong Hong said this discovery could have very practical applications.
He explained: “Instead of relying on invasive biopsies, doctors might be able to diagnose deep-seated tumours by simply examining a person’s tissue without the need for invasive surgical removal.
“This technique could potentially make blood draws less painful by helping phlebotomists easily locate veins under the skin.”
The discovery of a new way to potentially assess patients is the latest in a series of advancements this year as researchers understand more and more about the mechanics of the human body.
Earlier this year, a new non-invasive test for prostate cancer was announced with the invention of a urine test.
The new test is being lauded for its ability to detect prostate cancer much earlier. Speaking about the test Professor of Oncology Karim Fizazi said the test could determine the cancer’s aggressiveness.
They explained: “This test has the advantage of being much more precise than the Prostate Specific Antigen blood test. Even if this test seems very promising, it requires validation on a larger scale before one day being available in our laboratories.”
Professor Fizazi also commented on how a recent study had found that prostate cancer progression was slower in people who had a diet including plenty of fruits, vegetables, and seeds.
They said: “These results, even if they need to be confirmed, are encouraging. Moreover, numerous studies have already proven that such a diet, rich in antioxidants and with anti-inflammatory action, has a protective effect on the onset of cardiovascular diseases and diabetes.”
