Eating beef staves off cancer, scientists discover

Eating red meat and dairy could help to fight cancer, a new study suggests.

Scientists have discovered that a specific fatty acid found in beef, lamb and dairy products improves the body’s ability to attack and kill tumours.

The study, published in the journal Nature, also shows that patients with higher levels of the fatty acid – known as trans-vaccenic acid (TVA) – in their blood responded better to immunotherapy, suggesting that it could work as a nutritional supplement to complement clinical cancer treatments.

‘There are many studies trying to decipher the link between diet and human health, and it’s very difficult to understand the underlying mechanisms because of the wide variety of foods people eat,’ said co-author Professor Jing Chen, of the University of Chicago.

‘But if we focus on just the nutrients and metabolites derived from food, we begin to see how they influence physiology and pathology.

‘By focusing on nutrients that can activate T cell [immune] responses, we found one that actually enhances anti-tumour immunity by activating an important immune pathway.’

For the study, the team started with a database of around 700 known metabolites, small molecules that come from food, and assembled a ‘blood nutrient’ library.

They then screened the compounds in this new library for their ability to influence anti-tumour immunity.

After the scientists evaluated the top six candidates in both human and mouse cells, they saw that TVA performed the best.

‘After millions of years of evolution, there are only a couple hundred metabolites derived from food that end up circulating in the blood, so that means they could have some importance in our biology,’ said Professor Chen.

‘To see that a single nutrient like TVA has a very targeted mechanism on a targeted immune cell type, with a very profound physiological response at the whole organism level – I find that really amazing and intriguing.’

The team found that feeding mice a diet enriched with TVA significantly reduced the tumour growth potential of melanoma and colon cancer cells, as well as enhancing the body’s ability to infiltrate tumours.

They then analysed blood samples from hospital patients undergoing immunotherapy treatment for lymphoma and discovered that patients with higher levels of TVA tended to respond better to treatment than those with lower levels.

Finally, the study discovered that TVA enhanced the ability of an immunotherapy drug to kill leukaemia cells in patients.

However, the authors do not believe eating excessive red meat is the solution and hope to find similar results in plants.

Professor Chen added: ‘There is a growing body of evidence about the detrimental health effects of consuming too much red meat and dairy, so this study shouldn’t be taken as an excuse to eat more cheeseburgers and pizza.

‘There is early data showing that other fatty acids from plants signal through a similar receptor, so we believe there is a high possibility that nutrients from plants can do the same thing by activating the CREB pathway as well.’

“Trying to decipher the link between diet and human health “

I appreciate that statement but at the same time It’s ridiculous that the scientific community doesn’t already know that diet is related and relevant to nearly every ailment in the human body.
Kinda sounds like they are trying to tiptoe around the subject. Don’t want to commit out of fear of getting chastised.

'There is a growing body of evidence about the detrimental health effects of consuming too much red meat and dairy, so this study shouldn't be taken as an excuse to eat more cheeseburgers and pizza.”

Hmmm, contradict much? Ignorance abounds in that statement. There is no evidence, detrimental or otherwise, that shows any direct link to the consumption of red meat to cancer so that is a lie and to sit there and say in the article that there is evidence showing that red meat may kill cancer cells and then turn around and say just the opposite is is not only stupid but it’s piss poor journalism.
And, as is the case of most of these ludicrous studies on red meat causing cancer, they always fail to account for the fact that those who have eaten red meat and contracted cancer always eat lots of breads, seeds, grains, seed oils and sugar. Why no correlation there? Oh, that’s right, it doesn’t fit the agenda.

I appreciate that there might be some studies that are starting to bend in our direction but we need better journalism that holds the false scientific claims accountable for their falsehoods.

I wholeheartedly agree. I was a bit hesitant to post the article because of the way it wrapped up, but I was still excited by the headline and the positive evidence for meat consumption contained therein.
