A examine in over 25,877 adults found that individuals who consumed extra added sugar had a higher risk of developing heart disease and coronary issues compared to individuals who consumed much less added sugar (10).

Not only does increased sugar intake increase cardiovascular risk, but it might also increase risk of stroke (10).

Large amounts of added sugar in the shape of fructose overload your liver, resulting in nonalcoholic fatty liver disease (NAFLD), a condition characterised by extreme fat buildup in the liver (45Trusted Source).

An animal examine found that feeding mice a high-fructose diet for long periods of time led to the deterioration of their intestinal barrier, liver inflammation, liver tumors, and indicators of fatty livers compared to a control group (46Trusted Source).
