Onion’s flavonoids and phenolic content, added to its antioxidant properties help fight and eliminate cancer cells.

Between the purple onion and the black onion, Ana Molina establishes some differences. In the first variety, a greater presence of phytochemicals stands out, while in the second variety it shows the lower content of sulfur compounds, but better absorption of these. According to the nutritionist, the only restriction you may have on its consumption is for people who may find it indigestible due to Crohn’s disease, colon issues, or heartburn. To better digest it, he recommends consuming it once cooked.

Even so, for people that aren’t negatively affected, it’s recommended to consume it without cooking, as cooking reduces its content of vitamin C, phytochemicals, or sulfur compounds.
