What Are Net Carbs and Why Do They Matter?
Net carbs, also known as digestible or impact carbs, are the carbohydrates that are absorbed by your body and affect your blood sugar levels. For diets like the ketogenic diet, which strictly limits carbohydrate intake, tracking net carbs is essential for staying in a state of ketosis.
The calculation is straightforward: you simply subtract the dietary fiber from the total carbohydrates listed on a food's nutrition label. Fiber is a type of carbohydrate that your body cannot fully digest, meaning it has a minimal impact on blood sugar. This is why foods with high fiber content often have a much lower net carb count than their total carb count might suggest.
How Many Net Carbs Are in Different Types of Peas?
Not all peas are created equal when it comes to carbohydrate content. The type of pea and its preparation method significantly affect the final net carb count. For those following a strict low-carb diet, distinguishing between varieties is an important step.
For a standard cup (about 160g) of cooked green peas, the nutritional breakdown from the USDA is approximately 25 grams of total carbohydrates and 8.8 grams of dietary fiber. Using the net carb formula, this results in about 16.2 grams of net carbs per cup. This places cooked green peas on the higher end for vegetables, often classifying them as a "starchy" vegetable alongside potatoes and corn.
In contrast, other pea types offer a much lower net carb load. For example, a cup (160g) of raw sugar snap peas contains just 11.3 grams of total carbohydrates and 4.5 grams of fiber, equating to approximately 6.8 grams of net carbs. Similarly, snow peas have a very low carb count, with one cup of raw, whole pods containing about 3 grams of usable carbs and 2 grams of fiber. This makes snow peas and sugar snap peas much more suitable for a low-carb diet when consumed in moderation.
Can You Eat Peas on a Keto Diet?
Whether or not peas are suitable for a ketogenic diet largely depends on the type and quantity consumed. For individuals aiming for a daily net carb target of 20-50 grams, a full cup of green peas would consume a significant portion of their allowance, potentially knocking them out of ketosis.
However, incorporating smaller amounts of lower-carb varieties is a viable strategy for many. Sugar snap and snow peas, with their low net carb count, can be enjoyed as a side dish or added to salads in controlled portions without causing a significant carb spike.
Tips for including peas on a low-carb diet:
- Use as a garnish: Sprinkle a small handful of peas over a salad or soup to add color, texture, and nutrients without adding a lot of carbs.
- Pair with lower-carb veggies: Create a mixed vegetable medley with peas and other keto-friendly options like broccoli, spinach, or cauliflower to distribute the carbs.
- Practice portion control: Instead of a full cup of green peas, opt for a small side portion of a quarter or half-cup to keep net carbs in check.
- Choose the right pea: Prioritize sugar snap and snow peas over green peas when you need to keep carb counts as low as possible.
A Comparison of Pea Types: Carbs and Nutrients
| Pea Type | Serving Size | Total Carbs | Dietary Fiber | Net Carbs | Notable Nutrients |
|---|---|---|---|---|---|
| Cooked Green Peas | 1 cup (160g) | 25.0g | 8.8g | 16.2g | Protein, Vitamin K, Vitamin C, Thiamin |
| Raw Sugar Snap Peas | 1 cup (160g) | 11.3g | 4.5g | 6.8g | Very good source of Vitamin C and K |
| Raw Snow Peas | 1 cup (63g) | 5.0g | 2.0g | 3.0g | Vitamin K, Vitamin C |
The Health Benefits of Peas
Regardless of their carb content, peas offer a wealth of health benefits due to their rich nutritional profile. They are packed with vitamins, minerals, and antioxidants that contribute to overall wellness.
- Excellent source of plant protein: A single cup of cooked green peas provides more than 8 grams of plant-based protein, which is beneficial for muscle repair and satiety.
- High in fiber: The generous fiber content promotes healthy digestion, supports a healthy gut microbiome, and helps regulate blood sugar levels.
- Rich in antioxidants: Peas contain polyphenols and carotenoids that offer anti-inflammatory and cancer-protective properties.
- Good for heart health: The combination of fiber and heart-healthy minerals like magnesium and potassium can help lower cholesterol and regulate blood pressure.
- Supports eye health: Lutein and zeaxanthin are antioxidants found in peas that are vital for maintaining good eye health.
- Low glycemic index: The low GI of green peas means they release sugar slowly into the bloodstream, making them a diabetic-friendly food in appropriate portions.

Conclusion: Making Informed Choices with Peas
While peas are undeniably a nutritious and healthy food, their classification as a starchy vegetable means they carry a higher net carb load than non-starchy green vegetables. For those on a standard diet, a full cup of peas is a fantastic source of protein, fiber, and micronutrients. However, for individuals closely monitoring their net carb intake, such as those on a ketogenic diet, the type of pea and the portion size are critical considerations.
Green peas, with over 16 grams of net carbs per cup, should be consumed in moderation, while lower-carb alternatives like sugar snap and snow peas can be enjoyed more liberally. By understanding how to calculate net carbs and making mindful choices based on pea variety, you can continue to enjoy the health benefits of this versatile legume while staying on track with your dietary goals.
Low-Carb Alternatives to Peas
If the net carb count of green peas is too high for your diet, many other low-carb vegetables offer similar nutritional benefits without the carbohydrate load.
Some excellent high-fiber, low-carb vegetable options include:
- Broccoli: One cup of cooked broccoli has only 6 grams of net carbs and 5 grams of fiber.
- Spinach: A true low-carb powerhouse, cooked spinach has only 1 gram of net carbs per half-cup serving.
- Green Beans: Though technically a legume, they are much lower in carbs than green peas, with a cup of cooked green beans containing 3.5 grams of net carbs.
- Cauliflower: A very versatile low-carb vegetable, with 1 cup of cooked cauliflower having just 1 gram of net carbs.
