I used to think bread came in only two states: delicious when it’s fresh out of the oven, and… barely acceptable the next day. That was until I read a post by a radiation oncologist in Taiwan. It really stopped me in my tracks. I realized that the way I’d been eating bread all along might actually be one of the worst ways for my body.
According to Dr. Liao Chih-ying, the biggest issue with bread isn’t the bread itself, but how quickly its starch is absorbed. When you eat white bread the usual way, blood sugar can spike rapidly, forcing insulin to work overtime. Over the long run, this may create an unhealthy metabolic environment, especially for people at risk of serious chronic diseases.
What’s interesting is that the solution is incredibly simple: freeze the bread, then reheat it before eating. It sounds counterintuitive, but this cold–heat process turns part of the starch into resistant starch. This type of starch is digested more slowly, helps stabilize blood sugar, and is beneficial for gut bacteria. Some nutrition studies have also shown that this method can reduce post-meal blood sugar spikes, especially with white bread.
But freezing alone isn’t enough. What you eat with the bread matters just as much. The doctor recommends pairing bread with protein and healthy fats like eggs, nuts, avocado, or olive oil. When these are added, sugar enters the bloodstream more slowly, and your body doesn’t get “shocked” after a meal. I tried this myself, and the difference was noticeable—I stayed full much longer.
Another point many people overlook is sweet jam. Bread plus sugary jam is basically pouring fuel on the fire. If you like a sweet taste, fresh fruit or lower-sugar spreads are better alternatives. You don’t have to eliminate carbs entirely—just don’t turn them into a “sugar bomb.”
As for the practical steps, it’s actually very simple. Slice the bread when you bring it home, wrap it tightly, and put it in the freezer for about half a day. When you want to eat it, there’s no need to thaw it—just pop it straight into a toaster or air fryer until it’s lightly golden and crispy. One thing to avoid is burning it, since charred bread can produce compounds that aren’t good for your health.
What I like most about the doctor’s advice is how practical it is: eat smarter, not more restrictively. No one is telling you to give up bread or carbs entirely. You just need to understand what your body needs and make small adjustments to your daily habits.
Sometimes, disease prevention isn’t about anything fancy or extreme. It can be as simple as a familiar loaf of bread—eaten the right way—and suddenly your body can breathe a whole lot easier.
