Approximately 1 in 10 Americans hasdiabetes. The condition puts them at risk for long-termvision,kidney, andcardiac healthproblems.
The usual advice for managing diabetes is to participate inphysical activity, eat a diabetes-friendly diet with plenty of fiber-rich food, limit added sugars, and avoid cigarette smoking.
A new study published inThe Journal of Clinical Endocrinology & Metabolism,suggests that when people with diabetes eat certain foods—not just that they do eat those foods—might influence their health.
How Common Is Diabetes?
All in the Timing?
One of the biggest factors that people living with diabetes need to think about in terms of managing their health iswhat they eat.
People with diabetes are twice as likely to have heart disease or a stroke than people who don’t have diabetes.
Therefore, finding ways to reduce that risk is key. Eating certain foods is known to affect a person’s heart health—both positively or negatively, depending on the choices they make.
However, less is known about how the timing of eating certain foods affects health—especially for people with diabetes.
How Untreated Diabetes Affects Your Body
The Study
To look for a possible link between meal timing and health outcomes, researchers in China used data from theNational Health and Nutrition Examination Surveyon over 4,600 people with diabetes.
The researchers not only looked at what the participants reported eating but the times of day that they had their meals.
When the researchers looked at all the data, two key points stood out:
Qingrao Song, MD, ofHarbin Medical Universityin China, and one of the investigators of the study, concluded that “nutritional guidelines and intervention strategies for diabetes should integrate the optimal consumption times for foods in the future.”
Preventing Health Complications From Diabetes
What Experts Think
Many people who are managing diabetes try to plan their diets carefully. They may get hyper-focused on which foods are healthful and which ones they’re supposed to avoid.
Christine Byrne, MPH, RD, LDNThere’s no guarantee that eating or avoiding specific foods at specific times will prevent or cause heart disease.

There’s no guarantee that eating or avoiding specific foods at specific times will prevent or cause heart disease.
While patients might be interested in the idea, providers don’t necessarily feel the new research is enough to justify making that recommendation.
Christine Byrne, MPH, RD, LDN, a non-diet private practice dietitian, told Verywell that “it’s important to remember that association isn’t causation” when looking at the researchers’ findings.
“There’s no guarantee that eating or avoiding specific foods at specific times will prevent or cause heart disease,” she said.

More Research Is Needed
Mary Ellen Phillips, MPH, RDN, LD, a Texas-based Registered Dietitian Nutritionist and owner ofMilk & Honey Nutrition, LLC, told Verywell that while the findings were interesting, the study was “based on self-reported data, which can be inaccurate so we need to be cautious with our interpretation.”
According to Phillips, “changing up the time of day you consume certain foods would likely not have a negative impact, it just may not have the proposed positive effects mentioned here.”

“We can’t draw a line connecting a single dietary factor (for example, when we eat a certain food) to a single health outcome (such as long-term survival in people with diabetes),” Andrews said.
Christine Byrne, MPH, RD, LDNThere’s no one diet pattern or food list that works for everyone with diabetes. Different bodies react differently to various foods, macronutrients, and eating patterns.
There’s no one diet pattern or food list that works for everyone with diabetes. Different bodies react differently to various foods, macronutrients, and eating patterns.
Instead, Andrews said that “we have to step back and consider food groups, eating patterns, nutrient deficiencies or excesses; meal timing, food preparation methods, food enjoyment, physical activity, stress, sleep, social support, trauma, and so forth.”
The study did not convince Andrews that people with diabetes should only eat vegetables and drink milk at certain times of the day. However, he said that the findings “add to the idea that coordinating meals with our biological clock is one of the many factors that influence long-term health.”

Finding What Works for You
Even if they’re not using a timed strategy for eating, there are plenty of other steps people with diabetes can take to support their health.
Byrne said that for people managing diabetes, “it’s important to eat regularly and to create balanced meals and snacks that pair carbohydrates with protein and fat. This helps keepblood sugar steady.”
“There’s no one diet pattern or food list that works for everyone with diabetes. Different bodies react differently to various foods, macronutrients, and eating patterns,” Byrne said.
Study Shows Low-Carb Diets May Help Put Diabetes in Remission
If you have diabetes, Byrne said that “taking regular blood sugar readingsand learning how your body reacts to various foods is far more helpful than following blanket recommendations for foods to eat and foods to avoid.”
Ultimately, you’ll want to work with your healthcare provider to find a plan that works for you. They knowyour family history, lifestyle choices, andaccess to food—all of which are factors that influence how you manage your health.
What This Means For YouIf you have diabetes, there are many strategies you can use to stay healthy. Eating certain foods at specific times of the day might be part of a diabetes management strategy someday, but more research is needed before experts would recommend it.
