Researchers have reported significant findings supporting the nutritional benefits of Connecticut-grown sugar kelp. They found brown sugar kelp (Saccharina latissima) inhibits hepatic inflammation and fibrosis in a mouse model of diet-induced non-alcoholic steatohepatitis, a fatty liver disease.

In a paper published in the Journal of Nutritional Biochemistry by College of Agriculture, Health, and Natural Resources faculty Young-Ki Park, assistant research professor in the Department of Nutritional Sciences, and Ji-Young Lee, professor and head of the Department of Nutritional Sciences, the researchers reported significant findings supporting the nutritional benefits of Connecticut-grown sugar kelp. They found brown sugar kelp (Saccharina latissima) inhibits hepatic inflammation and fibrosis in a mouse model of diet-induced non-alcoholic steatohepatitis, a fatty liver disease.

They studied the differences between three groups of mouse models. They placed two on high-fat diets but incorporated sugar kelp, a kind of seaweed, into the diet of one. The third group was on a low-fat diet as a healthy control. The group that ate sugar kelp had lower body weight and less adipose tissue inflammation — a key factor in a host of obesity-related diseases — than the other high-fat group.

Consuming sugar kelp also helped prevent the development of steatosis, the accumulation of fat in the liver. Nonalcoholic steatohepatitis (NASH) is a condition often associated with obesity that can cause inflammation and reduced functionality in the liver.

The mice on the sugar kelp diet also had healthier gut microbiomes. The microbiome is a collection of bacteria and other microorganisms in and on our bodies. The diversity and composition of the microbiome are key to maintaining a host of health functions.

«I wasn’t surprised to see the data, as we know seaweeds are healthy,» Lee says. «But it’s still pretty amazing data as this is the first scientific evidence for health benefits of the Connecticut-grown sugar kelp.»

This study is the first time researchers have looked at the link between the US-grown sugar kelp and obesity.
