Highest growth-index pieces and decision-engine promote picks — still evidence-labeled, not medical advice.
A new study found that what you eat—not just which insulin you use—plays a significant role in how well your blood sugar stays in range after meals. The research compared two types of rapid-acting insulin in adults using an advanced closed-loop system.
Type 1 diabetes in children requires a coordinated strategy combining insulin therapy, nutrition, activity, and education. Understanding the tools and approaches available can help families navigate daily management and support better health outcomes.
A major study shows that even people with high genetic risk for Type 1 diabetes can lower their chances through healthier lifestyle choices. Genes matter, but they're not the whole story.
When type 1 diabetes develops in someone already living with phenylketonuria, nutrition management becomes especially complex. A detailed case study shows how coordinated care and individualized treatment can help.

Emerging research suggests low-carbohydrate diets may influence immune function in ways that could benefit autoimmune conditions, including Type 1 diabetes. But evidence is still limited, and the approach isn't right for everyone.
A new study shows that exercising sooner after a meal—rather than waiting longer—may help reduce the risk of low blood sugar in people with Type 1 diabetes. The type of insulin used also plays a role.
A Swedish study of young people with Type 1 diabetes found that learning to count carbs early doesn't automatically lead to better blood sugar control than learning later. The real benefit comes from actually using the skill consistently.
New research suggests that β-hydroxybutyrate, a ketone body naturally produced during low-carbohydrate diets, may help improve glucose control in Type 1 diabetes by working through a specific cellular pathway.
A new study tested whether online education programs and continuous glucose monitors could improve quality of life and blood sugar control in young people with Type 1 diabetes. Here's what researchers found.
A new technology can analyze pictures of meals to calculate carbohydrate content and suggest insulin doses—but it's designed to support, not replace, user expertise and decision-making.
For teenagers and young adults using automated insulin delivery systems, using simple meal categories may be just as effective as counting every gram of carbohydrates—and many people find it easier to stick with.
A small study found that people with Type 1 diabetes who followed low-carbohydrate diets before exercise spent more time in their target blood sugar range compared to those on high-carbohydrate diets.
A case study shows how continuous ketone monitoring can catch dangerous ketone buildup even when blood sugar looks normal—a risk that deserves attention for people on certain medications or following low-carb diets.
A new study found that following healthy eating patterns is linked to lower levels of inflammation and clotting markers in the blood—risk factors for heart disease in people with Type 1 diabetes.
A new study finds that children and teens with Type 1 diabetes who eat more pro-inflammatory foods tend to have higher blood sugar levels and signs of inflammation in their blood. Understanding dietary patterns may help families make informed nutrition choices.
A new study found that among lifestyle factors, sleep quality had the strongest link to how people with Type 1 diabetes rate their overall well-being. Diet and exercise still matter—but not as much as getting good rest.
A new study using continuous ketone sensors shows that mild ketosis is common—and usually harmless—when people with Type 1 diabetes follow very-low-carbohydrate diets. The findings offer reassurance and point toward better monitoring tools.
A new study comparing people diagnosed with celiac disease as children versus adults reveals that early diagnosis has both protective and complex effects on health later in life.
A growing number of families are exploring ketogenic diets to manage their child's blood sugar, but researchers caution that evidence of safety and long-term effects in children remains limited.
While carbohydrates get most of the attention in diabetes management, protein plays a surprisingly important role in how your body regulates blood glucose. Understanding protein's effect on insulin and glucagon could help you manage your levels more effectively.
A German survey found that about two-thirds of adults with Type 1 diabetes have received dietary counseling, yet the majority say they need more regular support with nutrition management.
Researchers analyzed 22 studies to see how two popular eating patterns affect blood sugar control in people with Type 1 diabetes. Here's what the evidence shows so far.
A major review of clinical trials reveals that intermittent fasting has benefits for type 2 diabetes, but evidence in type 1 remains limited. Here's what we know so far.
A new study of 217 adolescents reveals that managing life with Type 1 diabetes depends on far more than blood sugar numbers alone. Social connection, physical activity, and education play equally important roles.
A large study found that understanding carbohydrates helps people on insulin pumps achieve better blood sugar levels, but the benefit varies depending on which insulin delivery method you use.
A new study finds that people with Type 1 diabetes have stronger knowledge of carbohydrates than those with insulin-treated Type 2 diabetes. Understanding carbs is key to managing blood sugar effectively.
A large European trial is underway to see if an artificial intelligence tool can help people on insulin injections achieve better blood sugar control by giving personalized dose suggestions and automatically estimating carbohydrates from food photos.
A comprehensive review of recent studies reveals that several dietary approaches—including low-carbohydrate and plant-based options—can help adults with Type 1 diabetes improve blood sugar control and other health markers.
A new study compared how two popular eating patterns affect bone turnover markers in adolescents and young adults with Type 1 diabetes. Neither diet showed clear advantages for bone health over 24 weeks.
A real-world study of nearly 200,000 Omnipod 5 users shows that using simplified meal categories for insulin dosing produces comparable blood sugar results to traditional carbohydrate counting.
A small study found that the same short, intense workout caused different changes in blood glucose depending on whether people exercised in the morning or evening. The difference may be tied to natural hormone rhythms in the body.
A case study shows how nursing support can help adolescents with Type 1 diabetes adapt to their diagnosis and improve their overall well-being.
A study of 463 meals eaten by people with Type 1 diabetes shows that the type of food you eat—not just the carbs—affects how much insulin your body needs. Understanding these patterns could help with better blood sugar control.
A new simplified carbohydrate counting tool tailored to individual eating habits and insulin needs showed meaningful improvements in blood sugar control over six months. The approach works across different ages, backgrounds, and education levels.
Researchers are testing whether a mobile app that uses artificial intelligence to give personalized feedback can help people with Type 1 diabetes adopt healthier habits around food, activity, and overall lifestyle.
An FDA-approved device called the bionic pancreas is reducing the daily burden of insulin management for young people with Type 1 diabetes, allowing them to focus on school, sports, and life—not carb counting.
A new study surveyed hundreds of patients, parents, and doctors about their experiences with very low-carbohydrate approaches to managing Type 1 diabetes. Here's what they reported.
A small clinical trial comparing two eating approaches found that people with Type 1 diabetes on a low-fat, plant-based diet produced fewer greenhouse gas emissions than those following a portion-controlled diet. Here's what the research shows.
A new systematic review examines whether low-carbohydrate and intermittent fasting diets can help adults with Type 1 diabetes lose weight safely. The findings reveal important differences depending on how these diets are structured.
A review of research identifies the core self-care behaviors and factors that help people with Type 1 diabetes manage their condition while using continuous insulin infusion systems.
A new study finds that the time of day you do resistance exercise—and whether you've eaten—can meaningfully affect your blood glucose levels for hours afterward. The effect varies depending on whether you use insulin injections or a pump.
