Does Eating Pasta Raise Your Blood Sugar? Experts Offer Tips
Pasta is a go-to meal in countless American households, but if you’re monitoring your glucose levels, you might be questioning if that bowl of spaghetti is working against your health. Here’s what dietitians and diabetes specialists reveal about pasta, blood sugar, and alternative options worth exploring.
Does Pasta Spike Your Blood Sugar?
Indeed, pasta can elevate your blood sugar — but generally at a slower pace compared to other refined carbs like white bread or sweets.
“Since pasta is a carbohydrate, it breaks down into glucose during digestion, potentially raising blood sugar levels, especially when consumed alone or in large quantities,” Gina Hassick, M.A., RD, LDN, CDCES, NCC, shared with Eating Well.
The good news is that pasta’s structure may work to your advantage compared to other foods that increase blood sugar levels rapidly. “Pasta usually raises blood sugar more gradually than foods like white bread or sweets, thanks to its lower glycemic index,” Hassick explained. “The protein structure of pasta slows digestion, helping to prevent sharp blood sugar spikes compared to other refined grains.”
Gina R. Wimmer, M.Ed., RDN, LD, a registered dietitian nutritionist focusing on diabetes care at Mayo Clinic in Minnesota, noted a similar observation regarding the wider category of grains.
“Many people instinctively think of breads, cereals, rice, and pasta in the same category,” Wimmer noted. “While that’s accurate, white rice will likely increase blood sugars more rapidly than options like brown or wild rice.”
What Pasta Alternatives Are Best for Blood Sugar?
Experts suggest that certain substitutes for traditional pasta noodles can increase fiber and protein content, which helps mitigate glucose responses.
“Whole-grain or legume-based pastas can be advantageous for some individuals due to their higher fiber and protein content,” Hassick mentioned.
Banza, a company that creates noodles from chickpeas, claims its “Chickpea Pasta, Brown Rice Pasta, and Brown Rice Mac & Cheese have been tested for glycemic index and fall within the low-GI category.” They also emphasize that “individual responses can differ based on portion size, preparation, and meal composition.”
Health also highlights konjac noodles, edamame pasta, and lentil pasta as lower glycemic alternatives to traditional semolina pasta.
How Can You Cook Pasta to Lower Its Blood Sugar Impact?
Two simple kitchen techniques can minimize pasta’s effect on blood sugar. Both methods alter the starch structure to slow digestion.
“Overcooking pasta results in a softer texture that is digested faster, potentially leading to higher blood sugar spikes compared to al dente pasta,” Hassick advised.
Chilling and reheating pasta creates resistant starch, which acts more like fiber in the body. “Reheated pasta provides a good source of resistant starch, leading to a lower impact on blood sugar levels,” said Sheri Gaw, RDN, CDCES.
Health states that “Some studies suggest that the structure of pasta necessitates more chewing and resists breakdown during digestion. These larger starch-protein complexes are digested more slowly, which can help lower post-meal blood sugar.”
What Is the Right Pasta Portion for Blood Sugar Control?
“I recommend keeping pasta portions to about 1 cup cooked or 2 ounces of dried pasta,” Gaw advised. “Combine pasta with a generous helping of vegetables and 3–4 ounces of protein for improved blood sugar stability.”
Smaller servings also result in fewer total carbohydrates entering your system simultaneously. “Smaller portions of pasta naturally lead to reduced blood sugar responses because they limit total carbohydrate intake,” according to Health. Pairing pasta with non-starchy vegetables, lean proteins, and healthy fats is an effective strategy to keep pasta dishes from becoming major contributors to blood sugar spikes.
