Apple cider vinegar has been credited with curing everything from fever to warts. Many of its supposed benefits are unproven, but some experts think that adding a little of this sour liquid to your life may have some health benefits.

For example it appears to help with diabetes and blood sugar control. Some experts think that its long term effects are close to those of certain anti-glycemic drugs.

The best apple cider vinegar is cloudy and shows a blob in the bottle, the so called "mother", a concentrate in probiotics and beneficial bacteria, ready to support your immune function.

Take the precaution not to drink it undiluted. Its acidic content is so high that it could damage your tooth enamel and your esophagus. But it's perfect in salads, together with olive oil and salt.
