The British Heart Foundation (BHF) has issued a warning about five foods and drinks commonly perceived as healthy but which may increase the risk of cardiovascular disease. In an update on its website, the charity urged consumers to examine labels closely, as these gut-friendly products can be high in sugar or salt.
Kimchi, a fermented food rich in probiotics, is often made with large amounts of salt, which can raise blood pressure and increase the risk of heart attack or stroke. The BHF advises eating it in small portions and choosing lower-salt varieties.
Kombucha, a fermented tea, contains probiotics but many commercial versions have added sugars. Excess sugar can lead to weight gain, raising the risk of heart attack or stroke. The BHF recommends selecting options labelled 'no added sugar'.
Plain yoghurt contains live cultures beneficial for gut health, but flavoured or fruit-based yoghurts often contain added sugars and fewer live cultures. The BHF suggests choosing plain yoghurt with 'live and active cultures' and adding whole fruit for sweetness.
Smoothies made from whole fruits provide prebiotic fibre, but blending releases free sugars that can spike blood sugar levels. The BHF recommends limiting intake to one 150ml serving per day and adding nuts or seeds for protein and fibre.
Sauerkraut, another fermented food, is rich in probiotics but traditionally high in salt. Some shop-bought versions are pasteurised, which may reduce probiotic benefits. The BHF advises checking labels for salt content and considering unpasteurised options in moderation.
