You can fend off one of the deadliest diseases for men in their forties – lung cancer – by not smoking, but you knew that already, right?

What you might not know is that eating broccoli, kale, and other cruciferous vegetables (of the cabbage family), will reduce your chances of contracting the disease thanks to their cancer-fighting glucosinolates.

A Johns Hopkins University study found people who regularly ate cruciferous greens were 43% less likely to develop lung cancer. A separate study found that cruciferous vegetables can also cut your risk of prostate cancer.

Here are 3 of the best foods to eat as you get older:

KALE

Dark green veg like kale contains cancer-fighting glucosinolates, for a longer, healthier life

BLUEBERRIES

These fruits have high levels of antioxidants, to help slow the degeneration of DNA with age.

DARK CHOCOLATE

Not just an after-dinner treat, it can lower blood pressure and cut your risk of heart disease by 33%
