Trans-vaccenic acid in red meat and dairy enhances anti-tumor immunity, research reveals

05 Dec 2023 — New research reveals that a long-chain fatty acid — trans-vaccenic acid (TVA) — found in meat and dairy products enhances immune cell function and anti-tumor immunity in vivo. Rather than suggesting people increase their red meat and dairy intake as that has been linked to detrimental health effects, the researchers indicate that the nutrient can potentially complement clinical cancer treatment. 

Patients with higher levels of TVA in their blood also responded better to immunotherapy. Around 20% of the nutrient — found in beef, lamb and dairy products such as milk and butter — is broken down into byproducts, with the remainder circulating in the blood.
