Drinking sugary drinks with glucose or fructose for 10 weeks lowered a type of cholesterol called lipoprotein(a) in adults—glucose drinks by about 15% and fructose drinks by about 11%.

Drinking sugary drinks for 10 weeks, where they make up a quarter of your daily calories, lowers a type of cholesterol called lipoprotein(a) by about 13% in overweight and obese adults, no matter the size of the particles.

Drinking sugary drinks with fructose (like in soda) can make fat levels in the blood go up more than drinks with regular sugar, even in women who aren’t overweight.

Eating a lot of fructose for just one week can pile up fat in the liver and muscles of healthy men, and it spikes bad blood fats even more if they have a family history of type 2 diabetes.

For normal-weight women, eating meals sweetened with fructose (like in soda) might raise blood fat levels more than those sweetened with regular sugar, which could lead to heart risks over time—even if they're otherwise healthy.

If healthy men eat about 80 grams of sugar (like table sugar or fruit sugar) every day for 7 weeks, their body still burns fat normally in muscles and blood—but their liver starts making more fat.
