Study links stress hormone with higher blood sugar in Type 2 diabetes

Stress and depression are two of the major causes of a flatter cortisol profile. These sustained levels of cortisol make it much more difficult to control blood sugar and manage the disease, which is why it is so important for those with type 2 diabetes to find ways to reduce stress.

A study by researchers at The Ohio State University Wexner Medical Center and The Ohio State University College of Medicine documents a clear link between the stress hormone cortisol and higher blood sugar levels in people with type 2 diabetes.

The study published online in the journal Psychoneuroendocrinology.

“In healthy people, cortisol fluctuates naturally throughout the day, spiking in the morning and falling at night,” said Dr. Joshua J. Joseph, an endocrinologist and researcher at The Ohio State Wexner Medical Center’s Diabetes and Metabolism Research Center who led the study. “But in participants with type 2 diabetes, cortisol profiles that were flatter throughout the day, had higher glucose levels.”

Previous research has shown that stress and depression are two of the major causes of a flatter cortisol profile. These sustained levels of cortisol make it much more difficult to control blood sugar and manage the disease, which is why it is so important for those with type 2 diabetes to find ways to reduce stress.

“We have begun a new trial to examine if mindfulness practices can lower blood sugar in those with type 2 diabetes,” said Joseph, an assistant professor in the College of Medicine. “But this isn’t the only effective form of stress relief. It’s important to find something you enjoy and make it a part of your everyday routine.”

The relationship of cortisol with glucose levels was only observed in those with diabetes. However, Dr. Joseph and his team believe the stress hormone likely plays an important role in diabetes prevention and they continue to research the connection between cortisol and the development of diabetes and cardiovascular disease.

More than 30 million Americans have Type 2 diabetes, according to the Centers for Disease Control and Prevention. With Type 2 diabetes, your body doesn’t use insulin properly. Some people can manage their blood sugar levels with healthy eating and exercise, while others may need medication or insulin to help manage it.

“Most people with Type 2 diabetes know the importance of exercising regularly, eating a healthy diet, and getting plenty of rest. But stress relief is a crucial and often forgotten component of diabetes management,” Joseph said. “Whether it’s a yoga class, taking a walk or reading a book, finding ways to lower your stress levels is important to everyone’s overall health, especially for those with type 2 diabetes.”

Joseph collaborated with researchers at Johns Hopkins University; University of Maryland School of Medicine; University of California, Los Angeles; University of Michigan; Boston University and the National Institute on Aging, National Institutes of Health.

Eating too much protein is bad for your arteries, and this amino acid is to blame

Consuming over 22% of dietary calories from protein can lead to increased activation of immune cells that play a role in atherosclerotic plaque formation, driving the disease risk.

Published

University of Pittsburgh School of Medicine researchers discovered a molecular mechanism by which excessive dietary protein could increase atherosclerosis risk. The findings were published in Nature Metabolism.

The study, which combined small human trials with experiments in mice and cells in a Petri dish, showed that consuming over 22% of dietary calories from protein can lead to increased activation of immune cells that play a role in atherosclerotic plaque formation, driving the disease risk. Furthermore, the scientists showed that one amino acid – leucine – seems to have a disproportionate role in driving the pathological pathways linked to atherosclerosis, or stiff, hardened arteries.

“Our study shows that dialing up your protein intake in pursuit of better metabolic health is not a panacea. You could be doing real damage to your arteries,” said senior and co-corresponding author Babak Razani, M.D., Ph.D., professor of cardiology at Pitt. “Our hope is that this research starts a conversation about ways of modifying diets in a precise manner that can influence body function at a molecular level and dampen disease risks.”

According to a survey of an average American diet over the last decade, Americans generally consume a lot of protein, mostly from animal sources. Further, nearly a quarter of the population receives over 22% of all daily calories from protein alone.

That trend is likely driven by the popular idea that dietary protein is essential to healthy living, says Razani. But his and other groups have shown that overreliance on protein may not be such a good thing for long-term health.

Following their 2020 research, in which Razani’s laboratory first showed that excess dietary protein increases atherosclerosis risk in mice, his next study in collaboration with Bettina Mittendorfer, Ph.D., a metabolism expert at the University of Missouri, Columbia, delved deeper into the potential mechanism and its relevance to the human body.

To arrive at the answer, Razani’s laboratory, led by first-authors Xiangyu Zhang, Ph.D., and Divya Kapoor, M.D., teamed up with Mittendorfer’s group to combine their expertise in cellular biology and metabolism and perform a series of experiments across various models – from cells to mice to humans.

“We have shown in our mechanistic studies that amino acids, which are really the building blocks of the protein, can trigger disease through specific signaling mechanisms and then also alter the metabolism of these cells,” Mittendorfer said. “For instance, small immune cells in the vasculature called macrophages can trigger the development of atherosclerosis.”

Based on initial experiments in healthy human subjects to determine the timeline of immune cell activation following ingestion of protein-enriched meals, the researchers simulated similar conditions in mice and in human macrophages, immune cells that are shown to be particularly sensitive to amino acids derived from protein.

Their work showed that consuming more than 22% of daily dietary calories through protein can negatively affect macrophages that are responsible for clearing out cellular debris, leading to the accumulation of a “graveyard” of those cells inside the vessel walls and worsening of atherosclerotic plaques overtime. Interestingly, the analysis of circulating amino acids showed that leucine – an amino acid enriched in animal-derived foods like beef, eggs and milk – is primarily responsible for abnormal macrophage activation and atherosclerosis risk, suggesting a potential avenue for further research on personalized diet modification, or “precision nutrition.”

Razani is careful to note that many questions remain to be answered, mainly: What happens when a person consumes between 15% of daily calories from protein as recommended by the USDA and 22% of daily calories from protein, and if there is a ‘sweet spot’ for maximizing the benefits of protein – such as muscle gain – while avoiding kick-starting a molecular cascade of damaging events leading to cardiovascular disease.

The findings are particularly relevant in hospital settings, where nutritionists often recommend protein-rich foods for the sickest patients to preserve muscle mass and strength.

“Perhaps blindly increasing protein load is wrong,” Razani said. “Instead, it’s important to look at the diet as a whole and suggest balanced meals that won’t inadvertently exacerbate cardiovascular conditions, especially in people at risk of heart disease and vessel disorders.”

Razani also notes that these findings suggest differences in leucine levels between diets enriched in plant and animal protein might explain the differences in their effect on cardiovascular and metabolic health. “The potential for this type of mechanistic research to inform future dietary guidelines is quite exciting,” he said.

Additional authors of the study are Yu-Sheng Yeh, Ph.D., also from Pitt; Alan Fappi, Ph.D. and Vasavi Shabrish, Ph.D., both of the University of Missouri, Columbia; Se-Jin Jeong, Ph.D., Jeremiah Stitham, M.D., Ph.D., Ismail Sergin, Ph.D., Eman Yousif, M.D., Astrid Rodriguez-Velez, Ph.D., Arick Park, M.D., Ph.D., Joel Schilling, M.D., Ph.D., Marco Sardiello, Ph.D., Abhinav Diwan, M.D., Nathan Stitziel, M.D., Ph.D., Ali Javaheri, M.D., Ph.D., Irfan Lodhi, Ph.D., and Jaehyung Cho, Ph.D., all of Washington University School of Medicine, St. Louis; Arif Yurdagul Jr, Ph.D., and Oren Rom, Ph.D., both of the Louisiana State University Health Sciences Center; and Slava Epelman, M.D., Ph.D., of the University of Toronto.
