Harvard Medical School Researchers Conduct Blood Tests on 825 Mexican Women
C-reactive protein concentrations vary by up to 56% depending on carbonated beverage consumption
A study found that women who consume one paper cup (about 200 mL) of carbonated beverages every day have higher levels of blood inflammation. If the blood inflammation levels remain elevated for a long time, it can cause cardiovascular disease, metabolic syndrome, etc., so it is necessary to control the amount of carbonated beverages consumed.
According to the international academic journal The Journal of Nutrition on the 9th, a research team led by Martha Tamez of the Harvard Medical School Department of Public Health Medicine confirmed this fact by surveying 825 Mexican women from 2006 to 2008 on their family history of heart disease, menstrual status, level of physical activity, level of carbonated beverage consumption, and blood test results (CRP, leptin, C-peptide, etc.).
The researchers divided the participants into four groups based on their carbonated beverage consumption. The group that consumed the most carbonated beverages drank an average of 202.9 mL per day, while the group that consumed the least drank an average of 11.8 mL per day.
The C-reactive protein (CRP) level of the group that consumed the most carbonated beverages was 0.346 mg/dL, which was 56% higher than the 0.231 mg/dL level of the group that consumed the least.
CRP is a protein synthesized in the liver and secreted into the blood, and its concentration increases when inflammation occurs in our body. For this reason, it is used clinically as a primary marker of cell damage and inflammation, and is also used to predict cardiovascular disease, metabolic syndrome, etc. The normal CRP level is 0.5 mg/dL or less.
The research team measured ‘C-peptide’, a biomarker of blood insulin concentration, ‘adiponectin’, a fat-dissolving hormone, and ‘leptin’, an appetite-suppressing hormone. However, these values were found to be unrelated to the amount of carbonated beverage consumed.
The research team explained, “The sugar in carbonated drinks is quickly absorbed into the body, which causes hyperglycemia and hormonal imbalances such as insulin secretion.” They continued, “This paper is the first study to demonstrate that carbonated drink consumption is associated with an increase in CRP, a biomarker of inflammation and cardiovascular risk.”
