How Cooking Potatoes the Wrong Way Could Raise Your Diabetes Risk
Potatoes are a mealtime favorite in many American households, whether they’re served as French fries at a drive-thru or as mashed potatoes alongside roast chicken. But a new study published in The BMJ (research link) reveals that how you cook your potatoes may quietly shape your long-term diabetes risk. For busy women balancing family, work, and health, this research offers an eye-opening reason to rethink how potatoes appear on your plate.
New Research on Potatoes and Type 2 Diabetes Risk
The study examined data from three large U.S. cohorts, including more than 200,000 health professionals tracked over a period of 36 years. Every few years, participants detailed their diets, noting how often they ate French fries, baked potatoes, mashed potatoes, boiled potatoes, and whole grains. Researchers then monitored who developed type 2 diabetes over time.
Here’s what the numbers revealed:
- Eating French fries three times a week was linked to a 20% higher risk of type 2 diabetes.
- Eating boiled, baked, or mashed potatoes showed no significant increase in risk.
- Substituting potatoes with whole grains was tied to an 8% lower risk of type 2 diabetes.
- Replacing French fries with whole grains cut diabetes risk by nearly 19%.
The findings highlight a clear message: it’s not potatoes themselves that are harmful, but how we prepare them.
How Researchers Conducted the Study
This wasn’t a short trial or a small experiment. By following participants over decades, researchers could track eating patterns and lifestyle choices with impressive detail. Food frequency questionnaires were repeated regularly, and results were adjusted for calorie intake, body weight, activity levels, and other dietary habits.
The large sample size, long duration, and repeated updates strengthen the reliability of the results, showing consistent links between French fry consumption and diabetes risk.
Why French Fries Are the Biggest Culprit
French fries may be comforting, but they carry metabolic risks that boiled or baked potatoes don’t. Researchers point to several reasons:
- Unhealthy fats from frying oils – especially trans fats and reused oils.
- High-heat damage – frying produces compounds that can trigger inflammation.
- Extra calories – fries pack more energy per bite, encouraging overeating.
- Low fiber – unlike whole grains, fries digest quickly, spiking blood sugar.
Together, these factors create the “perfect storm” for blood sugar instability and long-term metabolic stress.
Smarter Potato Choices for Healthier Meals
The good news? You don’t have to cut potatoes out of your life completely. Instead, make small adjustments:
- Choose boiled, baked, or mashed potatoes instead of fried.
- Add more whole grains—think quinoa, farro, or whole wheat pasta.
- Limit fried foods overall, not just French fries.
- Practice portion control, since even healthier forms can add up.
Simple swaps can reduce diabetes risk while still letting you enjoy comfort foods.
Acupressure Points for Diabetes Support
In Traditional Chinese Medicine (TCM), food choices are only part of the picture. Energy balance in the body—guided by meridians and acupoints—also plays a role in metabolic health. By practicing acupressure at home, you can gently stimulate points that support digestion, blood sugar balance, and overall vitality.
For a full step-by-step guide, visit our detailed article on acupressure points for diabetes. Below are three key points to try right away:
LU 10 (Lung 10 / Yu Ji / Fish Border)
- Location: On the palm side of the hand, at the midpoint of the fleshy pad beneath the thumb, where the skin texture changes.
- Benefits: Supports the Lung system, which in TCM helps regulate fluids and works with the Spleen to process food and prevent dryness linked to blood sugar imbalances.
- How to use: Press with the opposite thumb for 30–60 seconds per hand, 2–3 times daily, especially after meals.
ST 44 (Stomach 44 / Nei Ting / Inner Court)
- Location: On the top of the foot, in the webbing between the 2nd and 3rd toes.
- Benefits: Clears excess heat from the Stomach meridian, curbs excessive appetite, and helps smooth digestion to reduce blood sugar spikes.
- How to use: Press firmly with your thumb in circular motions for 1–2 minutes per foot before meals.
KI 3 (Kidney 3 / Tai Xi / Supreme Stream)
- Location: In the hollow between the inner ankle bone and the Achilles tendon.
- Benefits: Nourishes Kidney Qi and Yin, which are vital for energy balance, metabolism, and resilience against stress.
- How to use: Apply steady pressure for 60–90 seconds per side, once daily.
Quick Daily Routine (5 Minutes)
- Start with LU10 on each hand (30–60 seconds).
- Move to ST44 on each foot (1–2 minutes).
- Finish with KI3 on each ankle (60–90 seconds).
Practiced regularly—3–4 times per week—this simple sequence can help regulate energy flow while complementing your healthier food swaps.
The Bottom Line
This landmark study shows that how you cook your potatoes matters more than the potatoes themselves when it comes to diabetes risk. French fries increase risk by about 20%, while boiled, baked, or mashed potatoes do not. Better yet, replacing fries with whole grains can lower your risk significantly.
Pairing smart dietary swaps with a short acupressure routine rooted in TCM provides a holistic path to supporting blood sugar balance. By combining modern science and traditional wisdom, you can enjoy comfort foods and still take charge of your long-term health.
