恐惧糖分摄入？科学研究让你无惧甜食诱惑！
Eating pastries, cakes, or chocolate bars every so often might be better for your heart than following a “zero-sugar” diet, according to researchers from Lund University in Sweden. However, this doesn’t apply to other sources of sugar, like fizzy drinks (which often have added sugar to enhance their sweetness) or sweet toppings.
“The most surprising finding from our study is how different sources of added sugar relate to heart disease risks,” says lead researcher Suzanne Janzi. “This highlights that it’s not just the amount of sugar that matters, but also where it comes from and the context.”
The researchers studied records of 69,705 people in Swedish public health databases. These participants, aged between 45 and 83, answered questions about their diet and lifestyle in 1997 and 2009 and were then tracked until 2019.
They categorized sugar intake into three groups: sugary toppings (like honey), sweet treats (like pastries and sweets), and sweetened beverages (like fizzy drinks). They then compared these types of added sugar with seven types of cardiovascular (心血管的) diseases, including strokes and heart attacks, while accounting for other risk factors like smoking.
The connections between sugar types and heart diseases varied; for example, sugary toppings were linked to a higher risk of abdominal aortic aneurysms (腹主动脉瘤). Overall, the lowest risks for all cardiovascular diseases were found in those who occasionally indulged in sweet treats.
When considering how we get our sugar, many factors matter: what else we eat or drink with the sugar, and how often we include added sugar in our diet. “Liquid sugars, found in sweetened beverages, usually make you feel less full than solid forms, which can lead to overeating,” says Janzi. “Context is important too — treats are often enjoyed socially or on special occasions, while sweetened beverages might be consumed more regularly.”
Keep in mind that these findings suggest relationships rather than proving cause and effect. “Our observational study can’t establish causation, but it suggests that extremely low sugar intake may not be necessary or beneficial for heart health,” says Janzi. The researchers recommend future studies to explore more details about the links between sugar, heart disease, and obesity.
