A prominent television doctor has made an urgent appeal to households across the nation, urging them to cease discarding what he terms 'liquid gold' from their daily diets. Dr Amir Khan, a regular contributor to BBC's Morning Live, took to social media to address a widespread kitchen habit that results in valuable nutrients being poured away.
The Hidden Power of Yoghurt's Watery Layer
Dr Khan explained that the thin, watery substance which frequently forms on the surface of yoghurt after refrigeration is not a sign of spoilage, but rather a concentrated source of nutrition. This liquid, known as whey, is a natural by-product created during the fermentation of milk into yoghurt.
"Nothing's spoilt, nothing is split, nothing is bad," Dr Khan reassured his audience during a demonstration. "Guys, I just want to say, you know this watery stuff that develops on the top of yoghurt overnight and stuff? Don't throw it away. I know it looks a bit odd, but it's actually meant to be there."
Why Whey Deserves Your Attention
According to dairy nutrition experts, whey represents a complete protein source containing all nine essential amino acids required by the human body. Once considered a waste product by the dairy industry, it is now recognised for its significant functional health properties.
The nutritional profile of whey includes:
- High concentrations of potassium
- Essential B vitamins
- Highly digestible protein
- Beneficial compounds for gut health
Substantial Health Benefits Backed by Research
Beyond basic nutrition, scientific research highlights multiple health advantages associated with consuming whey. The NHS has documented its role in blood sugar management, with a comprehensive 12-month study demonstrating that consuming small amounts of whey protein before meals can significantly help control glucose levels in individuals at risk of developing type 2 diabetes.
Key Health Advantages of Whey Consumption
- Blood Sugar Regulation: Whey protein stimulates insulin release and activates gut hormones that slow digestion, helping maintain stable glucose levels.
- Muscle and Bone Support: Its rich amino acid profile aids muscle repair and promotes bone strength, particularly valuable after physical exercise.
- Weight Management Assistance: When incorporated into a balanced diet, whey enhances feelings of fullness, supporting appetite control and sustainable weight management.
- Gut Health Enhancement: Consuming whey provides direct nourishment to beneficial gut bacteria found in fermented foods like yoghurt, supporting digestive wellbeing.
Dr Khan's simple recommendation is to stir the liquid whey back into the yoghurt rather than discarding it, ensuring you receive the full nutritional benefits of this fermented food. This small adjustment to food preparation habits could contribute meaningfully to overall health and wellbeing for countless individuals.
