Reasons Why Beans, Soybeans, and Nuts Are Being Reconsidered as "Filling Foods"

When you walk through supermarkets or convenience stores, you'll notice products labeled "high protein," "protein-enriched," or "X grams of protein." It's no longer uncommon to see high-protein products in items like yogurt, bread, soup, snacks, and beverages.

There's no doubt that protein is important for maintaining muscles and body building. However, some people find themselves hungry shortly after eating high-protein foods and end up reaching for snacks or bread.

This is where the combination with dietary fiber should be reconsidered.

Simply increasing protein doesn't necessarily guarantee long-lasting fullness. Many factors influence satisfaction, including the form of the food, moisture content, fats, carbohydrates, eating speed, and the overall amount of the meal. Among these, foods that provide both protein and dietary fiber are gaining attention as a choice that can balance meal satisfaction and nutritional balance.

Dietary fiber left behind in the high-protein boom

Protein serves as a building block for muscles, skin, organs, and is involved in various bodily functions. For those who want to maintain muscle mass as they age or have an exercise routine, getting enough protein is important.

On the other hand, many modern high-protein products contain little dietary fiber.

For example, refined protein drinks and high-protein desserts offer convenient protein supplementation but cannot replace vegetables, beans, or whole grains. Many people may choose products by only checking the protein content on the nutritional label, without considering dietary fiber, fats, sugars, or energy content.

According to the guidelines introduced by the German Nutrition Society in the original article, it is recommended that healthy adults consume more than 30 grams of dietary fiber per day. However, it is said that many people do not meet this requirement.

Here lies the blind spot of the high-protein boom.

Protein is often prominently advertised on the front of packaging, while dietary fiber is less noticeable. Therefore, it's important to not only consider "how many grams of protein have I consumed," but also "how much beans, vegetables, seaweed, fruits, and whole grains have I eaten."

Why combining the two leads to greater satisfaction

Meals containing protein generally support post-meal satisfaction. On the other hand, dietary fiber is not easily broken down by human digestive enzymes, increases the bulk of food, and some types have the ability to absorb moisture.

Foods containing both of these elements tend to require more chewing than simply drinking a protein shake. The time spent chewing and the ability to feel the quantity and texture of the meal are important factors for satisfaction.

However, it cannot be uniformly stated that "eating this food will keep you full for hours." Fullness varies from person to person and is also influenced by factors such as lack of sleep, stress, exercise, eating habits, and the total energy content of meals.

The key is not to think of protein or dietary fiber as an either-or choice, but to base your meals on foods that contain both.

Legumes as a versatile and accessible ingredient

Legumes such as lentils, chickpeas, black beans, kidney beans, and peas are representative foods that provide both plant-based protein and dietary fiber.

The benefits of legumes are not limited to nutrition. In addition to dried beans, canned, steamed, and frozen options are available, and they can be stored for a relatively long time. Many products are more stable in price compared to meat or fish, allowing you to increase the quantity of your dishes while keeping food costs down.

They can be used in a variety of ways.

Chickpeas can be added to salads and curries, or made into hummus when mashed. Some types of lentils require little soaking time and can be easily mixed into soups, meat sauces, and keema curry. Soybeans and mixed beans can be used in rice dishes, hijiki stew, and tomato stews.

You don't need to replace all meat with beans. Small changes, such as substituting part of the ground meat with lentils or reducing the amount of white rice and adding bean soup, can increase dietary fiber.

This idea of "not over-replacing" is important for sustainability. Even healthy ingredients won't last if you're not accustomed to their taste or texture. Starting with dishes where the flavor of beans blends well with the overall dish, such as curry or soup, makes it easier to incorporate them.

Tofu is not the only soy food option

Soybeans are a type of legume, but they are characterized by their diverse forms, such as tofu, natto, soy milk, edamame, and tempeh.

Soy protein is known for containing essential amino acids in a balanced manner among plant-based foods. However, not all soy foods have the same nutritional composition.

While soy milk and smooth tofu are easy to eat, some dietary fiber may be removed during the manufacturing process. Edamame, natto, steamed soybeans, and tempeh, which are closer to whole soybeans, make it easier to incorporate both protein and dietary fiber.

Edamame, in particular, has the advantage of being easy to prepare. By heating frozen edamame in a microwave or boiling water, you can quickly prepare a dish. Eating a small amount as a snack instead of sweets or sweet bread can increase chewing.

Tempeh is not yet common in Japan, but it is a fermented and solidified soybean product that can be used in stir-fries, teriyaki, and sandwich fillings. It has a firmer texture than tofu, making it suitable for those seeking a more substantial meal.

The basic rule for nuts and seeds is "use small amounts wisely"

Almonds, walnuts, pistachios, and peanuts contain protein, dietary fiber, and unsaturated fatty acids. Seeds like chia seeds, flaxseeds, pumpkin seeds, and sesame seeds can also enhance the nutritional density of meals.

The convenience of nuts is that they can be eaten as they are. They are easy to carry on the go and can be added to yogurt, oatmeal, or salads to enhance texture and satisfaction.

However, it's important to be mindful of the quantity.

Nuts are high in fat, so even a small amount can be high in energy. Continuously eating directly from the bag based on the perception of being healthy can lead to consuming more than expected.

Instead of eating nuts in large quantities like a staple food, it's better to portion them out on a small plate, use individually wrapped packages, or use them as toppings for dishes to keep the amount visible.

Additionally, products coated with sugar or heavily salted differ from plain roasted nuts. If you want to make it a daily habit, unsalted or lightly seasoned products are more suitable.

Combining whole grains makes meals more balanced

It's important to not only focus on beans, soy, and nuts but also on how you choose your staple foods.

While it's not necessary to completely avoid white bread, refined noodles, or white rice, replacing some with whole grain bread, oatmeal, brown rice, barley, or whole grain pasta can increase dietary fiber.

The food culture of combining legumes and grains exists around the world. Beans and rice, lentils and bread, chickpeas and whole grains are combinations that not only taste good together but also provide protein from different foods.

For breakfast, add soy milk, nuts, and seeds to oatmeal. For lunch, sandwich hummus and vegetables between whole grain bread. For dinner, serve stir-fried tofu and vegetables with brown rice.

Without buying special nutritional foods, you can increase both protein and dietary fiber by slightly rearranging your usual meals.

"Prepping beans" is supported on social media

Looking at related posts on social media, methods for cooking legumes all at once and freezing them in portions are repeatedly introduced.

One idea is to boil lentils in bulk and gradually add them to ground meat dishes, soups, pasta sauces, and salads. Since there's no need to cook from scratch each time, the psychological barrier to bean dishes is lowered.

Comments such as "I'm replacing part of my staple food with lentils," "There's little discomfort when mixed into meat sauce," and "Sweet potato and red lentil soup is easy to make" can be seen.

For snacks, frozen edamame, roasted chickpeas, dried peas, and bean-based crisps were mentioned as candidates. It seems that people concerned about the calories in nuts are looking for bean-derived snacks.

These posts highlight that not only nutritional content but also "easy to store," "easy to carry," and "ready to eat" are keys to continuation.

"Beans don't guarantee fullness for everyone"

Social media contains not only positive reactions but also questions and concerns.

A common concern is "increased beans lead to bloating." People who have had a low-fiber diet may experience gas and bloating when they suddenly consume large amounts of beans or whole grains.

When increasing dietary fiber, it's practical to start with small amounts and gradually increase while monitoring your condition. It's also important to drink enough water and properly heat the beans.

Regarding nuts, there are opinions such as "there's a sense of fullness, but they're high in energy" and "it's hard to manage the amount once you start eating." Conversely, from those who want to consume a lot of energy to build muscle, there are voices saying "too much dietary fiber makes it too filling to eat the required amount."

In other words, strong fullness is not always an advantage for everyone.

For those who want to manage their weight, it can help prevent overeating, but for those with small appetites, such as the elderly, growing children, or those who exercise intensely, being too full can prevent them from getting the necessary energy.

It's necessary to adjust the ingredients and amounts according to the purpose.

Read social media experiences as "hints"

Social media is full of posts about cooking methods and ways to continue from people who have actually tried them. It's very useful as a place to get cooking ideas.

However, individual experiences like "I wasn't hungry all day after eating this" or "I lost weight just by eating this food" should not be taken as scientific conclusions.

There is a large individual difference in hunger, and results vary depending on the overall content of meals and lifestyle habits. The method that worked for the poster may not necessarily work the same way for you.

It's important to use social media voices as hints for meal planning and cooking, and to combine them with information from public institutions and experts when making nutritional decisions.

The easiest way to continue is to "add," "mix," or "replace a part"

When thinking of a healthy diet, people tend to imagine making big changes like quitting meat, banning white rice, or completely avoiding sweets. However, extreme rules are hard to maintain.

It's best to start by adding small amounts to your current meals.

Add steamed beans to salads.
Add lentils to soups.
Add a small amount of nuts or chia seeds to yogurt.
Mix barley or soybeans into white rice.
Replace part of the ground meat with beans.
Make part of your snacks edamame or plain roasted nuts.

These small adjustments can be continued without significantly changing your taste or lifestyle rhythm.

Without continuously purchasing expensive high-protein products, you can expand the satisfaction and nutritional range of your meals by combining familiar foods like beans, soy products, nuts, seeds, and whole grains.

Being conscious of high protein itself is not bad. However, instead of just chasing the protein amount displayed on the package, attention should also be paid to dietary fiber, fats, energy content, and the degree of processing of the entire food.

What truly supports a diet is not drastically increasing one nutrient. It is about combining multiple foods and continuing to eat the amount that suits your condition and purpose without strain.
