Glutamate Fact: Cancer Growth

Researchers have discovered a troubling connection between glutamates and cancer behavior. When cancer cells were exposed to glutamates—including MSG—they became significantly more mobile. In fact, the glutamate‑exposed cells developed pseudopodia (tiny “feet” used for movement) and began migrating through tissue. This increased mobility is a key factor in metastasis, the spread of cancer.

But mobility isn’t the only concern.

Studies also found that elevated glutamate levels caused cancer cells to grow rapidly—almost like wildfire. When researchers blocked glutamate activity, cancer growth slowed dramatically.

Even more promising, when glutamate‑blocking drugs were combined with conventional chemotherapy, the cancer treatments became noticeably more effective.

These findings raise an important question: if glutamates can influence cancer growth and spread, how much exposure are we getting from our food and personal‑care products?
