Type 1 Diabetes and Diet: New Insights from Vegan and Moderate-Carbohydrate Studies

Type 1 Diabetes


When it comes to managing Type 1 Diabetes, the question of how many carbohydrates to include in your diet can be quite challenging. One universal dietary solution doesn’t apply to everyone, as highlighted by two recent studies presented at the “Are We What We Eat?” symposium during the EASD 2023 conference in Hamburg, Germany. These studies offer valuable insights into the role of diet for individuals with Type 1 Diabetes and aim to broaden the conversation surrounding this condition.

A Plant-Based Approach

Dr. Hana Kahleova, director of clinical research at the Physicians Committee for Responsible Medicine in Washington D.C., led a study comparing a plant-based diet to a standard portion-controlled diet for individuals with Type 1 Diabetes. Her goal was to reduce insulin dependence, as higher insulin doses have been linked to various health concerns. Kahleova referred to the Diabetes Control and Complications Trial (DCCT), which demonstrated a connection between higher insulin doses and increased cardiovascular risk over 30 years.

The current recommendations for Type 1 Diabetes management emphasize portion control, carbohydrate counting, and the avoidance of processed foods and sugary beverages. However, patients often report inconsistent responses to meals with similar carbohydrate levels, leading to confusion and frustration. Kahleova stressed the significance of considering factors beyond just carbohydrates, such as fiber content.

Type 1 diabetes diets

The average American consumes only half of the recommended daily fiber intake, which is about 16 grams per day. In Europe, the average intake is slightly higher at around 20 grams daily, but it still falls short of the recommended amount. Studies have shown that higher fiber intake (30-35 grams daily) is associated with a 15% reduction in all-cause mortality compared to a low-fiber diet. For individuals with diabetes, this deficiency in fiber may contribute to a 45% increase in all-cause mortality and a 39% rise in cardiovascular disease.

Kahleova explored whether the benefits of a plant-based diet, previously established for Type 2 Diabetes, could also apply to Type 1 Diabetes. In a small study involving 58 individuals with Type 1 Diabetes, she found encouraging results:

  1. Energy intake remained stable in both groups.
  2. The vegan group increased carbohydrate intake from 200 g to 300 g daily, while reducing fat content to maintain consistent calorie levels.
  3. The portion-controlled group maintained a steady macronutrient ratio.
  4. The vegan group experienced a significant 28% reduction in daily insulin dose.
  5. Insulin sensitivity increased by 144% in the vegan group.
  6. Both groups saw reductions in A1C levels, with the vegan group showing a larger decrease.
  7. The vegan diet led to an 11.5-pound weight loss.
  8. Both diets led to reduced total cholesterol, with the vegan diet showing more significant improvements, particularly in LDL cholesterol levels.
  9. Kidney function improved in the vegan group compared to the portion-controlled group.

Kahleova emphasized that while a high-carbohydrate diet might seem daunting at first, the key is to keep fat content low and select carbohydrates as the primary energy source.

Moderating Carbohydrate Intake

Sofia Sterner Isaksson, from the University of Gothenburg, Sweden, conducted a study exploring varying carbohydrate ratios in diets for Type 1 Diabetes. Her research compared a moderate-level carbohydrate diet (30% of daily energy from carbohydrates) to a traditional diet (50% of daily calories from carbohydrates).

The study, involving 50 individuals with Type 1 Diabetes, revealed that the moderate carbohydrate diet led to improved glucose control. Participants on this diet experienced a 5% increase in the average time spent in the desired glucose range and a 6.4% reduction in time spent with glucose levels above the range. Additionally, the moderate group reported higher treatment satisfaction, with no increased risk of hypoglycemia, dyslipidemia, ketoacidosis, or elevated blood pressure compared to the traditional diet groups.


The findings from these two studies underscore the importance of personalized dietary approaches for individuals with Type 1 Diabetes. A plant-based diet with higher carbohydrate and fiber content may be beneficial for some, while a moderate carbohydrate diet could work better for others. It’s clear that there’s no one-size-fits-all solution, and more research is needed to understand the diverse dietary needs of those with Type 1 Diabetes. These studies offer hope and encourage individuals to explore new dietary options to support their health and well-being.
