Rice Noodles Nutrition Calculator — Pad Thai, Pho, Stir-Fry & Soup

Cooked rice noodles provide 108 calories per 100g — 18% fewer than cooked wheat pasta (131 kcal) and 17% fewer than regular white rice (130 kcal) ^[1]. A typical serving in a pho bowl (200g noodles) delivers approximately 216 calories from the noodles alone, before broth, meat, and garnishes are added.

The calorie advantage comes with a protein trade-off: rice noodles contain only 0.91g protein per 100g cooked — a fraction of wheat pasta's 5.8g and white rice's 2.69g ^[1]. This makes rice noodles almost entirely a carbohydrate source, with 24.9g carbs per 100g representing over 92% of total calories. Fat is negligible at 0.2g.

For anyone choosing rice noodles as a gluten-free pasta alternative, the protein gap is the most important nutritional consideration. A 200g serving of rice noodles provides less than 2g protein, while the same amount of wheat pasta delivers over 11g. Adding protein-rich accompaniments — tofu, eggs, shrimp, beef — is essential for a nutritionally balanced meal.

Rice noodles are manufactured from rice flour and water, producing a product that is essentially pure rice starch in noodle form ^[1]. The extrusion and drying process results in an even lower protein content than cooked rice (2.69g/100g), because the noodle-making process further concentrates the starch fraction while diluting the already-modest protein.

In dry form, rice noodles contain 3.44g protein per 100g ^[1] — roughly half the protein in dry wheat pasta (12.5g) and less than half of dry white rice (7.13g). This means rice noodles cannot serve as a meaningful protein source in any meal. They function purely as an energy and texture component.

The fiber content of 1.0g per 100g cooked is better than white rice (0.4g) but far below whole-wheat pasta (4.5g). Mineral content is minimal across the board: calcium 4mg, iron 0.14mg, potassium 4mg, magnesium 3mg ^[1]. Rice noodles are nutritionally the lightest of the common noodle types — which can be an advantage when the goal is a low-calorie, low-allergen carbohydrate base.

The nutritional identity of a rice noodle meal is determined almost entirely by what surrounds the noodles rather than the noodles themselves. A typical Pad Thai (250g serving) delivers approximately 413 calories, 16.3g protein, 18.8g fat, and 47.5g carbohydrates — with most of the protein, fat, and flavour coming from egg, peanuts, tamarind sauce, and cooking oil rather than the noodles.

By contrast, a bowl of pho (500g total with broth) provides approximately 225 calories, 17.5g protein, and 5g fat — a dramatically different profile despite using the same base noodle ^[1]. The broth-based preparation keeps fat low, while sliced beef or chicken adds substantial protein. The high sodium (approximately 1,900mg per bowl) is the primary nutritional concern with pho.

Stir-fried rice noodles (like Char Kway Teow or Singapore noodles) fall between these extremes at approximately 140 kcal per 100g with 4.5g fat from cooking oil ^[1]. The key insight for accurate tracking is that rice noodles themselves contribute primarily calories and carbohydrates — everything else in the nutritional profile comes from the dish's other ingredients.

Among Asian noodle types, rice noodles sit in the middle of the calorie spectrum. Cooked wheat noodles (egg noodles) provide approximately 138 kcal per 100g with 4.5g protein. Cooked wheat pasta provides 131 kcal with 5.8g protein. Cooked rice noodles provide 108 kcal with only 0.91g protein ^[1].

Glass noodles (mung bean vermicelli) are the lowest-calorie option at approximately 82 kcal per 100g cooked — 24% fewer than rice noodles — but with even less protein (0.1g) ^[1]. Shirataki noodles (konjac-based) have essentially zero calories but lack any macronutrients entirely.

For a gluten-free option that prioritises low calories, rice noodles are a practical choice. For a gluten-free option that prioritises protein, soba noodles (100% buckwheat) at 99 kcal and 5.0g protein per 100g offer a substantially better protein-to-calorie ratio. The right choice depends on whether calories, protein, allergen avoidance, or texture is the primary concern.

Rice noodles are naturally gluten-free, making them a safe carbohydrate source for people avoiding gluten ^[1]. Unlike wheat pasta, which relies on gluten proteins for structure, rice noodles use rice starch gelatinisation to achieve their texture. This makes them compatible with gluten-free eating patterns without needing speciality formulations.

However, being gluten-free doesn't mean being nutrient-rich. Rice noodles provide almost no vitamins — vitamin C, vitamin A, vitamin E, and B-vitamins are all at trace levels or zero ^[1]. The only micronutrient present in a meaningful amount is selenium at 3.5 mcg (6% DV), which is naturally present in rice starch.

Enrichment is rare in rice noodle products (unlike enriched rice or enriched wheat pasta), which means the micronutrient gap compared to wheat pasta is wider than the calorie difference suggests. When rice noodles form the base of a meal, the nutritional quality of that meal depends almost entirely on the accompanying ingredients — protein, vegetables, herbs, and cooking fats must carry the micronutrient load.
