An increased diet of free sugars - both added sugars and those found naturally in honey and fruit juice linked to an increased risk of cardiovascular disease, according to a study. The findings support the global dietary recommendation to limit free sugar consumption to less than 5 percent of total daily energy consumption.
The findings of the study were published in BMC Medicine. Rebecca Kelly and colleagues analysed data from 110,497 individuals from the UK Biobank who had completed at least two dietary assessments. The researchers tracked individuals for around 9.4 years and during this time, total cardiovascular disease (heart disease and stroke combined), heart disease, and stroke occurred in 4,188, 3,138, and 1,124 participants, respectively.
The authors found total carbohydrate intake was not associated with cardiovascular disease outcomes. However, when looking at the types and sources of carbohydrates consumed, they found that higher free sugar intake from foods such as sugary drinks, fruit juice and sweets, was associated with increased risk of all cardiovascular disease outcomes.
For each 5% higher total energy from free sugars, the associated risk of total cardiovascular disease was 7% higher. The authors found that the risk of heart disease was 6% higher, while the risk of stroke was 10% higher. Additionally, consuming five grams higher fibre per day was associated with 4% lower risk of total cardiovascular disease, but this association did not remain significant after accounting for body mass index (BMI).
The authors suggest that replacing free sugars with non-free sugars - mostly those naturally occurring in whole fruits and vegetables - and a higher fibre intake, may help protect against cardiovascular disease.
