FAQs About Phytochemicals

Phytochemicals are natural compounds found in plants that help them survive everything from insect attacks to sunburn. For us, they offer a range of health benefits, from boosting antioxidant levels to supporting metabolism – basically, they’re the plant world’s version of multitasking overachievers.

Supplements can help, but you’re better off getting your phytochemicals from actual plants. Whole foods provide a mix of phytochemicals, fibre, vitamins, and minerals that just can’t be crammed into a capsule. Plus, your body likes its nutrients with a side of context – you know, like how coffee tastes better in a mug than from a test tube.

Nope! While many phytochemicals have antioxidant properties, others support heart health, balance hormones, or even help your body detox. Think of them like the Avengers – each one has a different superpower.

Short answer: probably not, unless you’re on an all-kale diet. Most people struggle to get enough, not too much. That said, moderation is key – your gut will thank you.

Some, yes – heat and light can reduce the potency of certain phytochemicals. That’s why it’s a good idea to mix things up – eat some foods raw, some cooked, and some lightly steamed. Variety isn’t just the spice of life, it’s the key to a happy gut.

Simple – eat the rainbow (and no, we don’t mean candy). Fill your plate with colourful fruits, veggies, nuts, seeds, herbs, and spices. Your cells will thank you.
