Professor Tim Spector, an epidemiologist and founder of Zoe Health, has highlighted popcorn as a surprisingly fibre-rich snack that could significantly reduce the risk of heart disease. In a video on Instagram, he noted that over 90% of adults in the US and UK do not consume enough fibre, leading to a depletion of the gut microbiome. He emphasised that fibre is crucial for gut health and reduces the risk of diabetes, stroke, and heart disease.
According to Professor Spector, a new meta-analysis of over 8,000 adults found that increasing fibre intake by just five grams per day could decrease heart disease risk by around 14%. He recommends reaching the daily target of 30 grams of fibre, which is achievable by including high-fibre foods like popcorn. Popcorn provides 14.5 grams of fibre per 100 grams, making it an excellent choice.
The American Heart Association supports this, stating that air-popped, lightly seasoned popcorn is a healthy whole grain linked to lower risks of heart disease, diabetes, and some cancers. However, they caution against popcorn loaded with sugar or butter. Professor Spector also listed other high-fibre foods, though details were not specified in the source.
A 2022 study in BMC Medicine cited by Professor Spector found that fibre-rich diets reduced all-cause mortality and were associated with lower blood pressure, cholesterol, and blood sugar levels. The researchers concluded that promoting higher fibre intake could benefit patients with cardiovascular disease and hypertension.
The NHS recommends adults consume at least 30 grams of fibre daily, but most manage only around 20 grams. Increasing fibre intake through snacks like popcorn could help bridge this gap and improve overall health.
