Quality Carbs: Eat Carbs for Stable Blood Sugar and a Comfortable Gut

After forty, you might eat the same plate of rice and curry at lunch, only to find yourself so drowsy in the afternoon that your work slows down. Yet, when you get home, you still want to have the energy to talk with your children or grandchildren, walk through the market, or take care of yourself without being a burden. The carbohydrates in that meal should therefore be viewed through the lens of food pairings, preparation methods, and your own gut.

Carbohydrates are also found in beans, grains, fruits, pumpkins, yams, and many types of vegetables. When making a choice, ask yourself what you are pairing that carbohydrate with, and how it was prepared.

The source research uses an easy-to-remember rule: do not eat a naked carb. This means eating plain carbohydrates without protein or fat to slow them down. A familiar picture: eating two cookies with sweet coffee usually causes blood sugar to rise much faster. If you switch to a small cookie paired with unsweetened Greek yogurt, the blood sugar level usually rises more slowly.

Quality Carbs: Slowing Things Down with Food Pairings and Preparation

Protein, fat, and fiber help slow gastric emptying, allowing carbohydrates to enter the bloodstream gradually. Post-meal blood sugar numbers may become more stable, although the total carbohydrate amount still needs to be counted.

A clear example of a meal plate: half a plate of steamed rice, one boiled egg, grilled fish, and blanched vegetables. The body absorbs carbohydrates from the rice more slowly than if you were to eat plain rice with fish sauce.

Carbohydrate Form	Example	Common Result	How to Adjust
Plain Carbs	Plain rice, white bread, cookies	Rapid blood sugar rise, quick hunger	Add protein, fat, and fiber
Carbs Paired with Protein	Rice with egg, fish, tofu	Fuller for longer, slower blood sugar rise	Control rice portion size
Well-Prepared Carbs	Soaked beans, fully cooked grains, fermented foods	Easier to digest, reduces some antinutrients	Soak, boil, or ferment before eating
Processed Carbs	Crispy snacks, cereal, sweetened drinks	High energy, short-lived satiety	Keep as an occasional treat

lectin and antinutrients, such as phytate and oxalate, are another topic worth knowing. Plants produce these substances to protect themselves, and they are commonly found in beans, grains, seeds, and certain nightshade plants.

For healthy individuals, normal amounts from cooked food are usually manageable. However, if you have a sensitive gut, autoimmune conditions, joint pain, migraines, or bloating easily, these substances might be one of the triggers you should observe.

⚠️ caveat: lectin should not be viewed as everyone’s enemy. Evidence in humans is still conditional, and many plant foods provide fiber, vitamins, and phytochemicals that are good for health. The goal is to prepare food well and observe yourself.

Thai kitchens have had methods to reduce antinutrients for a long time:

1. Soaking beans or grains for at least 8 hours, then discarding the soaking water.
2. Boiling thoroughly especially red beans, black beans, and mung beans, which should be cooked until soft, not just briefly heated through.
3. Fermenting such as tempeh, fermented soybean paste, thua nao, or clean pickled vegetables, which helps microbes digest some of the substances before they reach the gut.

If you want to eat mung beans boiled with sugar, soak the beans first, boil them until tender, reduce the sugar, and eat them after a main meal instead of on an empty stomach.

The word “organic” does not always mean low lectin. Organic brown rice still contains antinutrients. Organic beans that are not soaked and fully boiled can still cause bloating. Look at the preparation rather than the label.

As for oatmeal, if you feel bloated after eating it, try soaking it overnight, boiling it until cooked, and pairing it with an egg or unsweetened yogurt instead of just pouring hot water over it and eating it quickly in the morning.

People who eat an animal-based diet may reduce their lectin intake because meat contains no lectins, but they must also be careful about lacking vegetables, fruits, and fiber. If you choose a middle ground, such as fish, eggs, leafy greens, low-sugar fruits, and well-prepared beans, it is usually more flexible.

3 principles for choosing quality carbs:

1. Eat carbs after vegetables, protein, and fat when possible.
2. Choose well-prepared carbs that have been soaked, boiled, fermented, or fully cooked.
3. Keep a food log for 2 weeks, noting bloating, acne, joint pain, post-meal drowsiness, and blood sugar levels if you are measuring them.

Start today with just one meal: eat your carbs after vegetables, protein, and fat, and note how your bloating, post-meal drowsiness, or blood sugar levels change. A carb that is good for one person might cause bloating or make another feel hungry quickly. You do not need to give up all carbs; simply choose the type, pairing, and preparation method that suit your body.
