Soybeans: A Keto-Friendly Superfood?

Soybeans are a popular food choice, packed with protein, fibre, vitamins, and minerals. But are they keto-approved? The answer is a bit nuanced. While some types of soybeans are keto-friendly, others are not suitable for a keto diet due to their carbohydrate content. Let's delve into the details and explore whether soybeans can be a part of a keto diet.

Soybeans are keto-friendly due to their low net carb content

Soybeans are indeed keto-friendly, but only if consumed in moderation. The keto diet recommends a daily intake of 50g of total carbs and 25g of net carbs for a person of average size. Net carbs are calculated by subtracting the grams of fiber and sugar alcohols from the total carbs. Soybeans are low in net carbs, with 2.36g of net carbs per 100g serving. This makes them a good option for those following a keto diet, as they can help you stay within the recommended net carb intake range of 20g to 30g per day.

However, it is important to note that not all soybean products are keto-friendly. While whole or fermented soybeans with minimal additives and processing are suitable, other products like soy milk, tofu, and some soy sauces are not recommended due to their higher carb content or processing methods. Additionally, soybeans are relatively low in fat compared to other legumes, which is not ideal for the keto diet.

When incorporating soybeans into your keto diet, it is crucial to stick to the recommended serving sizes and practice moderation. Soybeans can be a good source of protein, antioxidants, fiber, vitamin K, and folate. They also contain isoflavones, which can help reduce bone loss in older women.

In conclusion, soybeans can be a part of a keto diet, but it is important to choose the right types and forms of soybeans and to be mindful of your overall net carb intake.

Soy sauce is keto-friendly, but other soybean products like tofu and soy milk are not

Soybeans are considered a healthy food choice, packed with protein, fibre, vitamins, and minerals. However, their compatibility with a keto diet is a different question. The answer depends on the type of soybean and the specific keto diet an individual is following.

The keto diet is a very low-carb, high-fat diet. To achieve ketosis, the metabolic state where your body burns fat for energy instead of carbohydrates, you need to limit your daily carb intake to a specific threshold, typically between 20 and 50 grams.

Soybeans, in their whole form, are relatively high in carbs compared to other legumes. A 100-gram serving of soybeans contains 20.86 grams of net carbs, which is almost an entire day's allowance on a keto diet. This high carb content can make it challenging to maintain ketosis. However, some types of soybeans, such as black soybeans and edamame, are considered keto-friendly due to their lower carb content.

When it comes to soybean products, the situation becomes more nuanced. Soy sauce, for instance, is generally considered keto-friendly due to its low net carb count. Traditional soy sauce is particularly recommended as it has a lower sugar and sodium content than other brands. However, it's important to avoid brands that add sugar or sweeteners, as these can increase the carb count.

On the other hand, other soybean products like tofu and soy milk are not considered keto-friendly. Tofu, derived from condensed soy milk, still contains a significant amount of net carbs, posing a challenge to maintaining ketosis. Soy milk, while lower in carbs than whole soybeans, is often highly processed and can cause gut irritation and inflammation due to the presence of phytates and lectins.

While soybeans offer a range of nutritional benefits, their high net carb content makes them less than ideal for a strict keto diet. For those following a keto diet, it's best to limit or avoid soybean products like tofu and soy milk and opt for alternatives with lower carb counts.

Edamame beans are immature soybeans that can be added to a keto diet in moderation

Edamame beans are a unique type of legume. They are immature soybeans that are harvested early and steamed or boiled in their green shell. They are considered a healthier snack option than soybeans, as they have a higher protein and lower fat content. They are also rich in dietary fibre, which helps compensate for their overall carb content.

A 1/2-cup (75-gram) serving of shelled edamame has 9 grams of carbs. When you subtract its 4 grams of dietary fibre, it yields just 5 grams of net carbs. This is an acceptable amount for those on the keto diet, as long as you keep your portion size modest to help sustain ketosis.

Edamame beans are also a good source of vitamins and minerals, including iron, folate, vitamins K and C, and potassium. They have a low glycemic index, which means they don't spike your blood sugar like some other carbs.

While edamame beans are a type of legume, which are generally excluded from the keto diet, their unique nutritional profile means they can be consumed in moderation as part of a keto diet. However, not all preparations are keto-friendly. For example, the beans are often topped with salt, seasoned mixes, or glazes, which may add to the overall carb count.

Black soybeans are a keto-friendly alternative to other beans

Soybeans are not keto-friendly due to their high net carb content. A 100g serving of soybeans contains 20.86g of net carbs, which is already almost the entire daily carb allowance for people on the keto diet.

However, black soybeans, a rare legume native to China, can be a keto-friendly alternative to other beans. They are a black variety of the more common soybean and are considered the "Crown Prince" of beans in Japan. Black soybeans have a similar nutritional profile to regular soybeans, but they are not as soybean-like in taste. They are sweet and have a creamy smooth texture, making them extremely versatile.

A 1/2 cup (130g) serving of canned black soybeans contains 8 grams of carbohydrates, which is mostly fiber (7 grams) with a small amount of sugar. The high fiber content means that these beans will be digested more slowly, reducing the rate at which blood sugar rises. Black soybeans also contain some fat, mostly healthy unsaturated fat, and are a good source of plant-based protein, with 11 grams in a half-cup serving.

Black soybeans can be used as a substitute for higher-carb beans such as black, navy, and pinto beans in dishes like baked beans, refried beans, bean soup, chili, and bean salads. They can also be made into flour and used to make noodles, or roasted and ground into a powder for black soybean tea.

When cooking black soybeans, it is important to soak dried beans overnight and cook them in salted water to avoid mushiness. If using a pressure cooker, cook the beans on high for 20 minutes and let the pressure reduce naturally for 10 to 12 minutes. If cooking on the stovetop, cover and cook for 1 1/2 hours until tender, adding more water if necessary.

Soybeans are high in protein, fibre, vitamins and minerals

Soybeans are a nutrient-dense food, packing in protein, fibre, vitamins, and minerals. They are a great source of plant-based protein, with 36 grams of protein per 100-gram serving. This makes them a popular choice for vegetarians and vegans looking to increase their protein intake.

In addition to protein, soybeans are also a good source of dietary fibre, with 9.3 grams per 100-gram serving. Fibre is essential for digestive health, as it adds bulk to stool and promotes the growth of good bacteria in the gut. The high fibre content of soybeans also helps to lower cholesterol levels and reduce the risk of heart disease.

When it comes to vitamins and minerals, soybeans are an excellent source of potassium, folate, magnesium, calcium, iron, and thiamin. They are also a good source of plant-based iron, with 15.7 milligrams per 100-gram serving. Soybeans are particularly rich in minerals, including potassium, phosphorus, magnesium, and iron.

The health benefits of soybeans are extensive. They may help to lower cholesterol levels, boost digestive health, and reduce the risk of certain types of cancer. Soybeans are also a good source of isoflavones, which have been linked to a reduced risk of post-menopausal cancer and osteoporosis.
