Stay away from processed foods.  Try to increase the amount of real foods you eat.  Whole natural foods that come from the earth not a factory.

Here are a few suggestions:
Berries - strawberries, raspberries, blueberries, cranberries - nutrient, anti-inflammatory and fiber filled.
Nuts - shown to lower the risk of heart disease in moderation.
Veggies - especially brassica vegetables such as broccoli, kale, cauliflower, cabbage and brussel sprouts which contain powerful compounds found to fight types of cancer.

Get back to nature and fuel your body with wholesome goodness.
