There's a lot of talk about not eating too many acidic foods and having a slightly alkaline balance in your body for better health. There are nutrition experts on both sides of this theory -- some saying that an acidic body is a welcome host for cancer whereas an alkaline body is not a good environment for cancer to grow. Acidic bodies also are said to have more inflammatory diseases. I haven't read enough about it to come to my own conclusion, but from what I can see, it goes along with whole food eating. If you're eating processed foods, sugar, and too many animal products and starches, you're going to have more health problems. If you're eating a vegetable based diet with plenty of other whole foods, you'll have a stronger, disease-free body.
Here are some charts I found to show which foods are acidic or alkaline.
ALKALINE / ACIDIC FOOD CHARTS The charts below are provided for those trying to "adjust" their body pH through their diet. The pH scale is from 0 to 14, with numbers below 7 acidic (low on oxygen) and numbers above 7 alkaline. These charts are intended only as a general guide to alkalizing and acidifying foods. Note that there may be some discrepancies between foods included on these charts.*

Remember, you don't need to adhere strictly to the Alkaline side of the chart. You can still eat foods that are acidifying. Just make sure a good percentage of the foods you eat come from the akaline side of the chart (and keep your acidic foods whole!) Watermelon is one of the most alkalizing foods. Eat up in the summer! And add some slices of lemon to your water.
