RFF#15 – Spinach planted in the spring has higher antioxidant levels compared to spinach planted in the autumn

Basically, more light (see RFF#9) and a warmer growing temperature, lead to higher nutrient levels.

—I learned about this fact from: Terry LA, ed. Health-promoting properties of fruits and vegetables. CABI: Cambridge, 2011.


RFF#14 – Broccoli florets contain 7.7 times more antioxidants compared to the stem

For once, the better tasting part is actually better for you! But don’t forget, the stems have a lot of fiber, so they’re still worth eating.
