By Lisa Rapaport (Reuters Health) – Men who drink two or more glasses of soda or other sweetened drinks a day may have a greater risk of heart failure, a Swedish study suggests. Previous research has linked high consumption of sugary beverages with several risk factors for heart failure, including high blood pressure, high blood sugar, weight gain, diabetes and obesity, said study leader Susanna Larsson of the Karolinska Institute in Stockholm. To confirm the relationship between heart failure and sweetened beverages, Larsson and colleagues followed a group of about 42,000 men for an average of almost 12 years.
