Summary
In plain language
Research suggests that phytochemicals, which are naturally occurring compounds found in plants, may play a role in preventing dementia and managing its symptoms in older adults. These compounds have antioxidant and anti-inflammatory properties that can support brain health. While it's beneficial to include phytochemical-rich vegetables in your diet, it might be challenging to consume enough through food alone. Supplements and essential oils offer alternative ways to intake these helpful compounds. For seniors, incorporating these into their daily routine might support cognitive health, though it's important to discuss any new supplement or treatment with a healthcare provider.
