Did you know?

The color of red and purple grapes comes from anthocyanins — the same antioxidant compounds that make blueberries and blackberries healthy for dogs. The irony is that the same anthocyanins are beneficial in blueberries but coexist with the unknown toxic compound in grapes that causes kidney failure. This illustrates why the toxic compound in grapes is not the anthocyanins — since blueberries are safe — but something else unique to grapes that remains unidentified.

What You Need to Know

Red grapes are not more or less toxic than green or purple grapes — the color is irrelevant to toxicity. The unidentified compound causing kidney failure is present in all grape varieties. People sometimes believe certain grape varieties are safe based on anecdote but no variety has been proven safe. All grape color varieties seedless and seeded organic and conventional should be treated identically.
