Vitamin B2 ist in fast jedem gesunden Lebensmittel enthalten, das Sie essen. Wissenschaftler haben gerade herausgefunden, dass es auch Krebszellen hilft, am Leben zu bleiben

Great breakthrough for potential cancer treatments, absolutely nothing the average person needs to worry about from a dietary perspective as the slightly click baity title implies by specifically mentioning “every healthy food you eat”. Wasn’t necessary to connect those two. The breakthrough is that they found a way to disrupt the protection in tumors with roseoflavin.

So again, do not avoid vitamin B2/riboflavin it in NO way causes cancer lol. It’s *still* healthy 😉

> The instinctive reaction to this research might be to wonder whether cancer patients should avoid foods high in Vitamin B2, such as dairy, eggs, meat, and green vegetables. The researchers are careful to head off that conclusion, and for good reason.

>Vitamin B2 is essential to human health across dozens of biological processes. It is involved in energy metabolism, the maintenance of healthy skin and blood cells, the function of mucous membranes, and the activity of other vitamins, including B6 and folate. A deficiency of riboflavin causes a condition called ariboflavinosis, characterized by mouth sores, skin inflammation, and eye problems. The idea of restricting dietary Vitamin B2 in cancer patients who are already nutritionally vulnerable is not supported by this research and could cause significant harm.

> What the research actually points toward is a much more targeted intervention: not reducing systemic Vitamin B2 levels across the entire body, but finding ways to block riboflavin metabolism specifically within tumor cells. This is precisely why roseoflavin is interesting; it can interfere with riboflavin function in a potentially targeted way, and it occurs naturally, which gives researchers a starting point for developing derivatives that are more potent or more selective.

Clickbait title, AI images. Draw your own conclusion.

Maybe for a bit of context: this is basic biology, not clinical research. There is a lot of work needed to take this into the clinic (and as others have pointed out, there’s no reason that these results suggest avoiding B2).

The idea of targeting vitamins in cancer therapy is not new. A common chemo drug, methotrexate, is sometimes prescribed in cancer because it blocks B9 in fast growing cells (it is also an immunosuppressant, so prescribed for that use in autoimmunity). 

Every month, there’s some research claiming that a certain vitamin promotes the growth of cancer cells. It has been known for decades that cancer cells gorge themselves on vitamin C; there have even been treatment protocols designed to cause them to burst under osmotic pressure.

I expect to see „research“ one day claiming that dihydrogen monoxide causes cancer.

I would imagine most things that help keep normal cells alive also help keep cancer cells alive

Tomorrow on TV:

McDonald’s helps to kill cancer.
