Drinking apple cider vinegar on a regular basis could help manage type 2 diabetes, a US study has shown.
The distinctive vinegar, commonly used for home cooking and homeopathic medicines, has previously been linked to weight loss.
Now, a trial has found that consuming the ingredient at bedtime can help impact waking glucose concentrations in type 2 diabetes favourably.
The authors wrote: “Given the importance of maintaining acceptable blood glucose concentrations, there is much interest in identifying foods and diet patterns that will help individuals with diabetes manage their condition.
“Utilising a randomised crossover design with a three to five-day washout period between treatments, participants followed a standardized meal plan for two days, consuming either two tablespoons of apple cider vinegar or water at bedtime with one oz of cheese.”
The researchers said it works because “anti-glycaemic effect of acetic acid found in apple cider vinegar was attributed to reduced starch digestion and/or delayed gastric emptying”.

Each volunteer was randomly given either apple cider vinegar or a placebo drink and then asked to eat a meal consisting of a white bagel, butter and orange juice.
The research team discovered that those who had consumed the vinegar had increased insulin sensitivity and significantly reduced post-meal blood glucose and insulin levels.
The findings have been published in the Diabetes Care journal.
