Are the health claims about apple cider vinegar true?

Apple cider vinegar is made by mixing chopped-up apples with water and sugar, then allowing the mixture to ferment, turning some of it into acetic acid.
Despite being acidic and definitely something of an acquired taste, in recent years apple cider vinegar has become incredibly popular. At least a part of that is because of claims that it can help with everything from obesity to split ends and arthritis.
But which, if any, of the many different health claims made on its behalf stand up to scientific scrutiny? For Trust Me, I’m A Doctor we teamed up with Dr James Brown from Aston University to find out.
We started by testing a claim which does seem to have the most scientific credibility - the claim that drinking a couple of tablespoons of vinegar, diluted in water, before a meal will help you control your blood sugar levels.
To see if there was substance to this idea we recruited healthy volunteers and asked them to eat two bagels, after having fasted overnight. We measured their blood sugar levels before and after eating and, as we expected, bagel consumption was followed by a large and rapid rise in their blood sugar levels.
The next day we asked them to consume another two bagels, but this time we asked them to knock back a diluted shot of apple cider vinegar just before doing so. Finally, we repeated the test a few days later, but this time we got our brave volunteers to gulp down some dilute malt vinegar before the bagel.
It turned out that the apple cider vinegar, but not the malt vinegar, had a big impact, reducing the amount of sugar in the volunteers’ blood by 36% over 90 minutes.
Next, we wanted to see whether apple cider vinegar lived up to claims that it helps with weight loss, lowers cholesterol and reduces inflammation (which might help with conditions like rheumatoid/inflammatory arthritis and eczema).
We recruited 30 volunteers and divided them into three groups. Our first group were asked to drink two tablespoons of apple cider vinegar diluted in 200ml of water twice a day, every day, before a meal. The second group were asked to do the same with malt vinegar and the final group were given a placebo consisting of coloured water.
Two months later I met up with Dr Brown and our volunteers to find out how they had all got on.
But what did Dr Brown’s tests reveal?
I’m sorry to say, he told his expectant audience, "that none of you lost any weight."
That was disappointing, though not entirely surprising.
So apple cider vinegar probably won’t help anyone slim down, but it may help those who struggle with their blood sugar or cholesterol levels.
