L.O.V.E. sweet potato - hands down I always choose it over white potato - for it's benefits below - BUT - if you're going to have potatoes in general there are some considerations for making them MORE ALKALIZING (instead of acid) to the body.
Pesticides diminish the alkalizing potential of all foods. To obtain the most nutrition and alkalizing potential from potatoes, buy organic if you can and consume the skin when you can. An organic baked potato seasoned with parsley, sea salt and chives is far more alkaline-forming in the body than a conventional baked potato topped with butter, sour cream or cheese (these are more acid forming). Sea salt, vegetable salt and parsley are highly alkaline-forming in the body, as are most herbs and spices. Olive oil is another alkalizing food you can use in place of butter for added flavor and richness.
