Keto Diet: Legumes And Pulses, A Strict No-No

The keto diet is a low-carb, high-fat diet that can offer many health benefits. It is a way of eating that promotes foods high in healthy fats and proteins and low in carbohydrates. The diet works by causing the body's sugar reserves to deplete, which then starts breaking down fat to produce energy. The body responds by producing molecules known as ketones, which it uses as fuel.

Legumes and pulses, such as beans and lentils, are generally not allowed on a keto diet because they are considered high in carbohydrates. While they are nutritious and offer many health benefits, their carb content may be too high for a strict keto diet. However, some low-carb legumes, such as green beans, black soybeans, and edamame, can be included in a keto diet in moderation. Additionally, non-legume substitutes like mushrooms, eggplant, and avocado can be used as alternatives to legumes and pulses in a keto diet.

Legumes are high in carbohydrates

Legumes are a group of plant foods that belong to the Fabaceae family, often known as Leguminosae. They include beans, soybeans, chickpeas, peas, and peanuts. While legumes are a good source of plant-based protein, fibre, vitamins, and minerals, they are also high in carbohydrates, which can be an issue for those following a strict ketogenic diet.

The ketogenic diet, or keto, is a low-carbohydrate, high-fat diet designed to shift the body's energy source from glucose to fat. This shift results in the production of ketone bodies, leading to a state called ketosis, which can aid in weight loss and improve health for some individuals. To achieve and maintain ketosis, it is crucial to limit carbohydrate intake, typically restricting it to less than 50 grams per day.

Legumes, including beans, are primarily composed of carbohydrates. While some types of beans have lower carb content than others, most contain a significant amount of carbs. For example, a half-cup serving of black beans contains 12 grams of net carbs, while kidney beans and pinto beans have 13 and 15 grams of net carbs, respectively. Even chickpeas, which are often used in hummus and falafel, contain 18 grams of net carbs per half-cup. These high carb contents can quickly add up and push an individual out of ketosis, hindering their weight loss goals.

However, it is important to note that not all legumes are equally high in carbohydrates. Green beans and black soybeans, for instance, are considered keto-friendly due to their lower carb content. Green beans have only 2 grams of net carbs per half-cup serving, while black soybeans have 2 grams of net carbs per 1/3 cup. These legumes can be incorporated into a keto diet in moderate amounts without disrupting ketosis. Additionally, peanuts and peanut butter, while needing to be consumed in controlled portions, can also be included as they offer 3 grams of net carbs per 1/4 cup serving.

In conclusion, while legumes are a nutritious food group, their high carbohydrate content makes them unsuitable for a strict keto diet. However, some legumes, like green beans and black soybeans, can be enjoyed in controlled portions without compromising ketosis. For those who wish to include legumes in their keto diet, careful planning and portion control are essential to ensure they stay within their daily carb limits.

They can cause digestive issues

Legumes and pulses are not allowed on the keto diet because they can cause digestive issues. They are easily fermented by gut bacteria in the large intestine, which can cause excessive gas and digestive discomfort in some people. Legumes are also difficult to digest and may need to be avoided by people with digestive problems. They contain plant-based antinutrient compounds like phytates and lectins, which can prevent the body from absorbing crucial nutrients and may even damage the digestive tract.

Additionally, legumes are high in carbohydrates, which can interfere with the ketogenic diet's goal of maintaining ketosis. Ketosis is a state in which the body burns fat instead of glucose for fuel. To stay in ketosis, it is recommended to restrict carb intake to fewer than 50 grams of net carbs per day. Legumes, such as beans and lentils, are high in fibre and antioxidants but also in net carbs, which can quickly use up an individual's daily carb allotment.

While legumes offer many health benefits, such as being a good source of plant-based protein, fibre, vitamins, and minerals, their potential to cause digestive issues and interfere with ketosis makes them unsuitable for the keto diet.

They contain antinutrients

Legumes and pulses contain antinutrients, which are plant-based compounds that can prevent the body from absorbing crucial nutrients and may even damage the digestive tract. These antinutrients include phytates and lectins, which are present mainly in legumes and cereals. Phytates, or phytic acid, are found in legumes, peanuts, cereals, and oilseeds, and generally in all plant-based foods. They can reduce the bioavailability of minerals like calcium, iron, copper, and zinc, and affect their absorption. Lectins are sugar-binding proteins that attach to red blood cells and cause agglutination. They impair the transport and hydrolytic functions of the enterocyte and can cause damage to the intestinal tract, allowing bacteria to enter the bloodstream.

Other antinutrients found in legumes include tannins, saponins, protease inhibitors, and amylase inhibitors. Tannins are phenolic compounds that can precipitate proteins and form complexes with them, leading to a reduction in essential amino acids. Saponins are secondary metabolites found in plants, which can interact with the cholesterol group of erythrocyte membranes, leading to hemolysis. They also show inhibitory activity against digestive enzymes like amylase, glucosidase, trypsin, chymotrypsin, and lipase, which can cause indigestion-related health disorders. Protease inhibitors limit enzyme activity by forming protein-protein interactions, while amylase inhibitors regulate the breakdown of carbohydrates.

The antinutrient content of legumes can be reduced by using various traditional methods and technologies, such as fermentation, germination, debranning, autoclaving, and soaking. Soaking, for example, enhances the release of endogenous phytases, which are present in plant foods like almonds and other nuts and grains. It also increases the hydration level of legumes and cereals, making them soft and more easily digestible. Autoclaving and cooking also help to decrease the phytic content in legumes. Germination is another suitable method for reducing antinutrients as it activates the phytase enzyme, which degrades phytic acid.

They are a source of plant-based protein

Legumes and pulses are a great source of plant-based protein. They are a good substitute for meat and are popular worldwide. Legumes and pulses are also a good source of fibre and B vitamins. They are also said to be rich in essential nutrients, dietary fibre, and plant-based proteins.
