Quick takeaways
Treating diabetes with a focus on diet, specifically reducing carbohydrates and increasing fat intake, can be more effective than relying solely on insulin therapy.
In the field of diabetes, considering conflicting evidence and acknowledging limitations in current knowledge can lead to improved patient outcomes and treatment approaches.
Deep dives
The Unknown Unknowns in Diabetes Treatment
Before the discovery of insulin, patients with Type 2 diabetes could live longer by avoiding carbohydrate-rich foods. However, when insulin therapy was introduced, doctors believed that allowing patients to eat what they want and covering it with insulin was the best approach. This assumption led to long-term complications and health problems. If doctors had acknowledged what they didn't know and considered alternative approaches, they could have improved patient outcomes.
The Importance of Paying Attention to Negative Evidence
In the field of diabetes, doctors often focused only on the evidence that supported their opinions while disregarding conflicting evidence. For example, when Intensive Insulin Therapy was tested, it showed some benefits, but doctors ignored the negative effects such as weight gain and higher risks of low blood sugar. Had they paid more attention to negative evidence, they might have realized the flaws in their treatment philosophy earlier.
Embracing Disagreement and Embracing Uncertainty
The medical community and health associations often dismissed alternative approaches to diabetes treatment, labeling them as quackery. However, dismissing different perspectives prevents learning and improvement. Embracing uncertainty and acknowledging the limitations of current knowledge is crucial. Communicating uncertainty allows for better decision-making and prevents the harm that can arise from false certainty.
In "Rethinking Diabetes: What Science Reveals About Diet, Insulin, and Successful Treatments," science journalist Gary Taubes argues that when it comes to treating diabetes, a disease that one in five Americans struggles with, we need to focus on diet—particularly, fewer carbohydrates and more fat — over a reliance on insulin
