Are All Carbs Bad? Think Again.

Have you heard that all carbs are bad and should be avoided? It’s one of the most common nutrition myths—and it couldn’t be further from the truth. In fact, new research shows that certain carbs might help you live longer and age better.

In a major study published in JAMA Network Open, researchers found that eating high-quality carbohydrates in midlife increased the odds of healthy aging by up to 37%.

The Truth About Carbohydrates

There’s a huge difference between refinedWhole grain quinoa bowl with vegetables and legumes carbs and high-quality carbs:

  • Refined Carbs = white bread, pasta, pastries, sodas, and sugary snacks.

  • High-Quality Carbs = fruits, vegetables, legumes, and whole grains.

These “good carbs” are packed with fiber, vitamins, and minerals. They’re your body’s preferred fuel and play a key role in maintaining energy levels, brain function, digestion, and metabolic health.

What the Study Found

Researchers tracked 47,513 women for over 30 years as part of the Nurses’ Health Study. The goal? To see how midlife carb intake affected their ability to age without chronic disease, physical decline, or memory problems.

Here’s what they found:

  • Women who consumed high-quality carbs were 37% more likely to age healthfully.

  • Women who consumed refined carbs were 13% less likely to experience healthy aging.

In other words: not all carbs are created equal. It’s not about cutting carbs—it’s about choosing the right ones.

What Are the Healthiest Carbs to Eat?

According to the study, the best carbohydrates for health and longevity include:

✅ Whole grains (brown rice, quinoa, oats, bulgur)
✅ Legumes (lentils, chickpeas, black beans)
✅ Fruits (berries, apples, oranges, bananas)
✅ Vegetables (leafy greens, carrots, sweet potatoes)

These foods are naturally high in dietary fiber, which helps reduce inflammation, improve digestion, and stabilize blood sugar levels, especially important as we age.

Why You Should Avoid Refined Carbs

Refined carbohydrates—like white bread, pastries, chips, soda, and sugary cereals—are stripped of nutrients during processing. They often spike your blood sugar, leading to cravings, energy crashes, and increased risk of obesity, heart disease, and type 2 diabetes.

The Bottom Line

If you’re aiming for long-term health, don’t ditch carbs—ditch the wrong ones. Load your plate with fiber-rich, plant-based carbohydrates that fuel your body the right way.

You don’t need to go no-carb or keto to get results. Just swap the white bread for whole grain, add legumes to your salads, and focus on fruits and vegetables over processed snacks.

Healthy aging starts with what’s on your plate. And the science is clear: the healthiest carbs can be your best ally in staying vibrant and strong as you grow older.
