How Is Diet Quality Linked To Death Risk?

Data regarding the dietary habits of tens of thousands of adults in the United States suggest that those who follow healthful low fat and low carb diets have a lower overall death risk

Islamabad (UrduPoint / Pakistan Point News - 27th January, 2020) Data regarding the dietary habits of tens of thousands of adults in the United States suggest that those who follow healthful low fat and low carb diets have a lower overall death risk.A large new study has examined the link between diet type and total mortality."Diet plays an important role in [ ] public health, and suboptimal diet is estimated as the first leading cause of death and the third leading cause of disability-adjusted life-years lost in the [U.S.]," write Dr.

Zhilei Shan from the Harvard T. H. Chan school of Public Health in Boston, MA and colleagues in their new study paper.More specifically, the investigators wanted to find out if different types of low fat and low carb diet are associated with total mortality.Although there have been several studies into the links between diet and death risk, the researchers note that to their knowledge none have looked specifically at how low carb and low fat diets of different qualities may fit into the equation."Consumption of carbohydrates from refined grains and added sugars has been adversely associated with health outcomes, whereas consumption of carbohydrates from whole grains, nonstarchy vegetables, and whole fruits appears to be beneficial," explain the study authors.

Low fat, low carb, and mortalityDuring this time, the researchers recorded a total of 4,866 deaths, of which 849 were related to heart disease and 1,068 were related to cancer.Using the NHANES reports regarding people's macronutrient consumption, the researchers were able to infer different diet quality types.On the other hand, better quality low fat and low carb diets were associated with a lower total mortality risk.The researchers also report that "participants with a higher overall [low carb dirt score] score" indicative of a poorer quality diet "were more likely to be older and non-Hispanic white, to have higher [body mass index], educational level, income level, and cholesterol intake, and to have lower total energy intake."As for those with higher low fat diet scores, the investigators point out that they tended to be part of an ethnic minority group, to not smoke, to have lower weights, and to have lower cholesterol levels.When trying to find an explanation for the association between different diet quality types and mortality risk, Dr.

Shan and colleagues point out that many biological mechanisms could play a role.
