3. All Vegetables

You may already be aware that if you consume vegetables in general, except for tomatoes (which is technically a fruit), it will reduce the acidity within your body. Additionally, every important nutrient, including folate, is found in pretty much every vegetable around. You also need to take a folic acid or folate supplement while you are trying to conceive because it will help reduce the odds of neural tube defects in your unborn baby.
