Lemons
Why They're Healthy:
— Just one lemon has more than 100 percent of your daily intake of vitamin C, which may help increase "good" HDL cholesterol levels and strengthen bones.
— Citrus flavonoids found in lemons may help inhibit the growth of cancer cells and act as an anti-inflammatory.
Quick Tip:
Add a slice of lemon to your green tea. One study found that citrus increases your body's ability to absorb the antioxidants in the tea by about 80 percent.
