Rice is one of the world's most widely eaten staple foods, but its sugar content is often misunderstood. Plain rice is naturally very low in simple sugars — usually far below 1 gram per 100 grams after cooking. This Rice Sugar Per 100g Calculator lets you estimate the exact sugar in your serving based on rice variety, preparation method, and portion size.
If you are tracking sugar for diabetes, weight management, or a low-sugar diet, this tool makes it easy to see how rice fits into your day. It also shows total carbohydrates and the sugars as a percentage of total carbs, because the starch in rice matters more for blood sugar than the tiny sugar reading itself.
Use the quick serving buttons for fast comparisons, or enter your own portion in grams, ounces, or cups.
🧮 Rice Sugar Per 100g Calculator
Estimate the sugar content in your rice portion by variety, cooking state, and serving size.
How This Calculator Works
The calculator relies on typical USDA nutrient profiles for six common rice varieties. When you enter a serving size in grams, ounces, or cups, it first converts the amount to grams. For dry rice, 1 cup is treated as about 185 g; for cooked rice, 1 cup is treated as about 160 g. It then multiplies your gram weight by the sugar value per 100 g and divides by 100 to give the sugar in your portion.
Alongside sugar, the tool shows total carbohydrates in the same serving and the percentage of those carbs that come from simple sugars. It also compares your sugar result to the FDA's 50 g Daily Value for added sugars. Plain rice contains no added sugar, so this last number simply shows how small the natural sugar contribution is when you think about a whole day of eating.
Reference Data: Sugar in Common Rice Types
The table below summarizes the approximate values used by the calculator. Values come from commonly cited nutrition databases and are intended for meal planning, not laboratory precision.
| Rice variety | Sugar per 100 g dry | Sugar per 100 g cooked |
|---|---|---|
| White rice | 0.12 g | 0.05 g |
| Brown rice | 0.85 g | 0.35 g |
| Jasmine rice | 0.10 g | 0.05 g |
| Basmati rice | 0.10 g | 0.03 g |
| Wild rice | 2.00 g | 0.73 g |
| Sushi / glutinous rice | 0.15 g | 0.05 g |
Worked Examples
Example 1: cooked brown rice, 150 g. Brown rice has about 0.35 g sugar per 100 g cooked and 23.5 g total carbs per 100 g. Sugar in the serving is 0.35 × 150 ÷ 100 = 0.53 g. Total carbs are 23.5 × 150 ÷ 100 = 35.3 g. Simple sugars make up only about 1.5% of the carbohydrate.
Example 2: dry wild rice, 1 cup. The calculator treats 1 cup of dry wild rice as 185 g. Raw wild rice contains about 2.0 g sugar per 100 g, so the serving has 2.0 × 185 ÷ 100 = 3.7 g sugar. That is higher than white rice but still trivial next to a sweetened cereal, which can contain 12–15 g per serving.
Example 3: cooked white rice, 200 g. Sugar equals 0.05 × 200 ÷ 100 = 0.10 g. This is just 0.2% of the 50 g added-sugar Daily Value. The carbs, however, are about 57 g, which matters more for blood-sugar management.
Tips for Keeping Sugar — and Blood Sugar — in Check
Plain rice is not a sugary food, but its starch still affects glucose levels. Use these practical strategies:
- Pair rice with protein, healthy fats, and vegetables to slow digestion and reduce post-meal glucose spikes.
- Let cooked rice cool in the refrigerator for a few hours before reheating; this raises resistant starch content, which is fermented more slowly in the gut.
- Watch portion sizes. A measured cup of cooked rice weighs about 160 g, but restaurant servings are often double that.
- Choose brown, basmati, or wild rice if you want slightly more fiber and a lower glycemic response, but do not expect a meaningful drop in sugar because the difference is small.
- Be careful with sauces. A tablespoon of sweet chili sauce can add 10 g of sugar — far more than any plain rice portion.
Frequently Asked Questions
Does rice contain sugar?
Plain rice contains only trace amounts of simple sugars, generally 0.03 to 0.73 g per 100 g cooked, depending on the variety. It contains no added sugar unless it is seasoned, coated, or cooked in a sweetened broth.
Why does plain rice taste sweet when I chew it?
Saliva contains amylase, an enzyme that begins breaking starch down into maltose and short glucose chains. Maltose has a mild sweetness, so the longer you chew, the sweeter the rice can taste. This happens during digestion and is not the same as the sugar listed in nutrition facts.
Is brown rice lower in sugar than white rice?
Not meaningfully. Brown rice often shows slightly more total sugar because the bran layer contains more naturally occurring sugars and fiber. The difference is typically about 0.3 g per 100 g cooked, which is negligible in a normal serving. Brown rice's real advantages are fiber, magnesium, and a lower glycemic index.
Can I trust these numbers for meal planning?
Yes, for general planning. The values are based on published food-composition data and will get you within a few tenths of a gram for sugar. For clinical decisions, use the exact label on your package or consult a registered dietitian.
Limitations and Accuracy
All nutrient values are estimates. Rice cultivars, growing conditions, water absorption, and cooking times can change the weight and carbohydrate content by several percentage points. The 50 g reference is specifically for added sugars, so the Daily Value comparison shown by the calculator is a conceptual scale rather than a recommendation to limit natural sugars in rice to 50 g. This tool is for nutrition education and should not replace individualized medical advice.
If you're also tracking other foods, remember that the prepared dish can contain hidden sugars from marinades, sauces, broth, or seasoned mixes. To get a complete picture of your plate, calculate the rice separately and add the values from the other ingredients.
