Although overconsumption of added sugars is known to contribute to a host of health woes, including obesity and heart disease, some mechanisms behind the link have remained elusive. Now, a team of U.S. researchers has published findings in Cell Reports showing more sugar danger: Surplus sugar may cause our cellular power plants—called mitochondria—to become less efficient, reducing their energy output. When there is too much glucose in cells, which can happen from high sugar consumption, the lipid profile of the mitochondrial membrane can change, leading to a loss of optimal functioning.
