This is the vinegar that everyone’s been talking about! It’s been dubbed as a tonic for weight loss; type 2 diabetes, cholesterol as well as an elixir for hair skin and nails. It’s no wonder there’s so much hype around this ‘superfood’!
But what actually is apple cider vinegar and what does the real research say?
Apple cider vinegar is not new to the market; it has in fact been used for centuries to treat infections and wounds. It’s made from just apples, sugar and yeast and is made by first crushing apples and squeezing out the liquid. Bacteria and yeast then start a fermentation process, which then results in a vinegar being made.
1. Weight Loss
Can apple cider vinegar really help with weight loss? This has to be one of the top health claims associated with this vinegar. A commonly cited randomised, placebo-controlled trial showed that of 155 adults, those who consumed 1-2 tbsp. apple cider vinegar per day lost more weight than those who did not consume despite no differences in caloric intake.  However it’s important to note that there was only a very small difference in weight loss between the group, therefore whilst apple cider vinegar appears to have a small effect on weight loss, it should not be considered a magic bullet and attention to diet still need to be the main focus.
2. Blood Sugar Control
The effect of apple cider vinegar on blood sugar control has the most research behind it. 1-2 tablespoons of vinegar with a meal, has been shown to modestly lower post-meal blood glucose and insulin levels in both healthy participants and in those with diabetes. 
Whilst the mechanism is unclear, it may be due to delayed or reduce carbohydrate absorption from increased glucose uptake from the blood and insulin sensitivity.
This is a positive thing when it comes to diabetes prevention and management, however, it doesn’t necessarily mean that apple cider vinegar can reverse diabetes or that it can be relied upon as a treatment.
3. Lowers cholesterol
There a lack of evidence as to whether apple cider vinegar can lower cholesterol levels, and most of the positive research has been conducted on rats.  It’s important to remember that results from animal studies are interesting but cannot directly be extrapolated to humans. This means that much more research is needed before we can say that apple cider vinegar can be used to improve cholesterol levels.
4. Skin Glow
You may have heard about apple cider vinegar in relation to acne treatment, anti-ageing properties and even wound healing. However, to date, there isn’t enough evidence to prove that this is the case. Unfortunately, most of the claims around apple cider vinegar come from anecdotal claims rather than concrete facts.
Apple cider vinegar has often been touted as an inflammation fighter. There has been one small study involving around 30 people measuring a fall in C-reactive protein (a marker of inflammation), however, the results were so small they simply weren’t significant. As it stands there simply isn’t enough concreted evidence to say that apple cider vinegar can be used as a component to suppress inflammatio and more research is needed.
Apple Cider Vinegar is safe to consume for most and is a source of vitamins and minerals within the diet. But it’s important to only consume vinegar diluted in other foods such as salad dressings, marinades or even within water to avoid causing damage to tooth enamel.
