Top Doc, Daniel Nadeau, M.D., Answers Your Diabetes Questions

What do you believe is the most important change to make to your daily diet to prevent type 2 diabetes?

Dr. Nadeau points to large studies at the Harvard School of Public Health: Type 2 diabetes used to be called adult onset diabetes, and is striking people at younger and younger ages with rates skyrocketing globally. The good news is that it’s highly preventable.

  • Keeping weight in check and being physically active can help prevent most cases of the disease.
  • Choosing a diet rich in whole grains and healthy fats adds even more protection—skip the refined grains and sugary soda.
  • Limiting red meat and avoiding processed meat — including bacon, hot dogs, and deli meats — can also help lower diabetes risk.
  • Go for healthier protein sources instead, such as nuts, beans, poultry, and fish.

What are some warning signs for diabetes and steps that can be taken to prevent or control it?

“Excess thirst and urination are the major signs. Weight loss often points to T1D and insulin deficiency.”

What do you think the benefits of continuous glucose sensors are?

The goal is to have freedom and control. I once recommended pumps before sensors but sensors have become so accurate and easy to use that I often recommend them first and move to a pump later. Integrated pumps and sensors are available and more are in development. Because of awareness of glucose levels, sensors allow for better control without the lows in a way that has never been possible.
