Personalized Diabetes Prevention: Why Your Body Responds Differently to Food
Emerging research suggests that standardized dietary advice may be ineffective for diabetes prevention, as individual metabolic responses to food vary significantly. According to Ashwini Wagle, a professor of nutrition at San Jose State University, a Continuous Glucose Monitor (CGM) study revealed that even healthy foods, such as foxnuts (makhanas), can cause sharp blood sugar spikes in some individuals. Experts at a May 30 scientific symposium hosted by Arogya World in Menlo Park, California, emphasized that using a CGM to track personal glucose responses is a critical step toward identifying unique dietary triggers.
Why “Healthy” Foods Trigger Different Metabolic Responses
The assumption that a food is universally healthy often ignores individual metabolic variability. Ashwini Wagle reported that her own blood sugar jumped from 94 to 262 within 20 minutes of consuming foxnuts, a snack typically considered diabetes-friendly. Dr. Michael Snyder of Stanford University explains that diabetes is not a monolithic condition; it stems from various root causes, including muscle insulin resistance, hepatic insulin resistance, beta-cell defects, or incretin (GLP1) defects. Because the underlying mechanism of insulin resistance varies, the glycemic impact of specific foods differs from person to person.
Are South Asians at Higher Risk for Diabetes?
South Asian populations face a disproportionate burden regarding metabolic health. Data from the Masala study, presented by Dr. Alka Kanaya, shows that South Asians develop diabetes at a significantly lower Body Mass Index (BMI)—typically 23 compared to the standard threshold of 25. Furthermore, the study found that 23% of South Asians are diagnosed with diabetes, compared to 6% of the general American population. Dr. Kanaya notes that this is partly due to “ectopic fat” storage; rather than storing fat under the skin, South Asian bodies tend to accumulate it around vital organs, including the liver, heart, and within muscle tissue.
Can Lifestyle Changes Overcome Genetic Predisposition?
While genetics play a role, experts argue that diabetes is largely preventable through targeted lifestyle interventions. Nalini Saligram, founder of Arogya World, advocates for programs that integrate health education into schools and workplaces. According to Anita Sathe of the South Asian Heart Centre, a structured approach known as MEDS—Meditation, Exercise, Diet, and Sleep—is essential for managing stress and reducing the risk of lifestyle-related diseases. By focusing on plant-based nutrition and high-quality sleep, individuals may mitigate risks that are not entirely offset by physical activity alone.
Frequently Asked Questions
Does a low BMI mean I am not at risk for diabetes?
No. According to the Masala study, South Asians can store fat internally around the liver and heart even when they appear slim. Regular A1c testing is recommended regardless of BMI.
Is ghee bad for people with diabetes?
According to Ashwini Wagle, ghee is safe in very small quantities, such as a thin smear on a roti. However, because it contains 60% saturated fat, long-term or excessive consumption may negatively impact heart and metabolic health.
What is the most effective way to monitor glucose levels?
Dr. Michael Snyder and other experts recommend using a Continuous Glucose Monitor (CGM) to observe real-time blood sugar reactions. This provides a personalized map of which foods trigger spikes for your specific physiology.
Nalini Saligram’s organization, Arogya World, aims to reach 100 million people by 2030 through science-based prevention programs, including the mDiabetes app and Healthy Schools initiatives currently operating in cities like Mumbai and Bangalore.
