When we try to take care of our diet, one of the first headaches is knowing How many calories are in them? vegetables and cereals that we eat every day. It's not enough to know that they are "healthy": if you want to adjust your diet to gain muscle, lose weight, or simply eat better, understanding their energy content is key.
In this article you will find a complete guide in table format and practical explanation about the calories of the main cereals, their flours, breakfast cereals, bars and the most common legumes (lentils, chickpeas, beans, peas, soy, etc.), along with important nuances such as the difference between whole and refined, the role of fiber or the combination of macronutrients.
Why focus on the calories in legumes and grains?
Before we get to the tables, it's worth remembering that the Calories are not “enemies” by defaultThey are simply a measure of the energy that food provides us. What's important is the quality of those calories, their source (carbohydrates, proteins, fats), and how they fit into your daily needs.
The three macronutrients that provide energy are the carbohydrates and proteins (4 kcal per gram) and fats (9 kcal per gram). Alcohol, although not an "essential" nutrient, also contributes energy with 7 kcal per gram, something that is often overlooked.
In general, cereals and legumes are characterized by providing lots of complex carbohydrates and plenty of fiberwith a variable amount of protein and, with few exceptions, little fat. This means that, although the number of calories per 100g may seem high, we are talking about energy that comes with valuable nutrients.
The nutritional label on the packaging remains the most accurate source for a specific productHowever, the tables you will see below are an excellent reference to know at a glance what you are putting on your plate when you choose a type of cereal or legume.
Calories in whole grain cereals
Cereals in their most basic form (whole grain or minimally processed) are notable for their high starch content, good dose of fiber and Group B vitaminsas well as some minerals. In balanced diets, they are usually the basis of daily energy.
This group includes foods such as wheat, rice, corn, barley, rye, oats, millet, quinoa, and amaranth, as well as isolated starches from various cereals. Their caloric value is frequently around... 330-410 kcal per 100 grams raw.
| Food (100 g) | approximate calories |
| Buckwheat | 343 Kcal |
| Amaranth | 371 Kcal |
| Wheat | 314 Kcal |
| Rice (grain, variety not specified) | 387 Kcal |
| White rice (general cereal table) | 354 Kcal |
| Brown rice (general table of cereals) | 350-376 calories |
| Puffed breakfast rice | 389 Kcal |
| Whole grain oats | 367-401 calories |
| Barley | 323-373 calories |
| Rye | 350-408 calories |
| What's good | 345 Kcal |
| Miso (fermented derivative made from soybeans and cereal) | 209 Kcal |
| Quinoa | 306 Kcal |
| Flaxseed (linseed/linseed) | 567 Kcal |
| Wheat semolina (refined cereal) | 350-368 calories |
As you can see, there is a wide variety of values, but they all fall within the range of 300-400 kcal per 100 g, except for flaxseed, which is boosted by its contribution of healthy fat (it is a food very rich in omega-3) and therefore has about 567 kcal.
The opposite case would be that of the miso, which, being a fermented product made from soy and cereals And while it contains a large proportion of water in ready-to-use versions, it has a clearly lower caloric content, although it provides protein and other interesting compounds.
Caloric differences between whole grains and refined grains
One of the most frequent questions is whether the Whole grain cereal has fewer calories than refined grain cereal.The answer, when we look at the official tables, is that the difference in kilocalories is usually small, but it exists.
Refining grain removes the bran and, in many cases, part of the germ. It is precisely in this bran where the nutrients are concentrated. much of the fiber, vitamins and mineralsBy removing these parts, the fiber content decreases, the caloric density per gram may increase slightly, and above all, nutritional value is lost.
| Food (100 g) | approximate calories |
| White rice | 387 Kcal |
| Brown Rice | 376 Kcal |
In the example of rice, it can be seen that the integral provides slightly less energyBut, beyond the number of calories, its strength lies in the fact that it provides more fiber and a higher concentration of protein and micronutrients than its refined version.
This pattern is repeated in other cereals: wholemeal bread versus white bread, wholemeal pasta versus traditional semolina pasta, etc. Wholemeal bread is usually slightly less caloric and much more nutritious.Therefore, if your goal is to take care of your health in the long term, it is the most recommended option.
Calories in breakfast cereals
Breakfast cereals have become a a product for daily consumption by both adults and childrenAnd this is where it's important to scrutinize the labels closely. Even if the base is a cereal, they often come with added sugar, honey, chocolate, or fats.
The official Spanish database (BEDCA) collects approximate averages of different commercial types, and in general the caloric values are between 356 and a little over 410 kcal per 100 g, with variations depending on the extra ingredients.
| Breakfast cereal (100 g) | approximate calories |
| Wheat and chocolate base cereals | 385 Kcal |
| Rice and chocolate base cereals | 388 Kcal |
| Rice and honey base cereals | 385 Kcal |
| Base cereals: rice, wheat and fruit | 356 Kcal |
| Corn and honey base cereals | 394 Kcal |
| Base cereals: corn and wheat | 381 Kcal |
| Base cereals: corn, wheat and oats | 416 Kcal |
| Wheat-based cereals (sweetened) | 385 Kcal |
| Base cereals: wheat and rice | 380 Kcal |
| Wheat-based cereals and fruit | 367 Kcal |
| Base cereals: wheat and honey | 397 Kcal |
| Base cereals: wheat, oats, corn and honey | 398 Kcal |
| Base cereals: wheat, oats, corn, honey and nuts | 393 Kcal |
If you pay attention, Cereals that include fruit usually have a slightly lower energy contentWhile those containing honey or chocolate tend to be somewhat higher in calories, mainly due to the added sugar and, in some cases, the fat in the toppings.
Within this group, the most sensible thing to do is to choose cereals with a short ingredient list, with a high content of whole grain and without too much added sugar, or versions with dried fruit without extra sugar.
Cereal flours and their caloric content
Cereal flours are used for bread, pastries, pasta, and thickeners, so it's worth keeping that in mind. What calories do they provide per 100 grams?because it's very easy to make too much when we cook "by eye".
In the market we find both wholemeal and refined flours, and also flours obtained from legumes or nuts (such as chickpea or chestnut), although in this section we will focus on those made from classic cereals.
| Cereal flour (100 g) | approximate calories |
| Oatmeal | 353 Kcal |
| barley flour | 361 Kcal |
| Rye flour | 359 Kcal |
| Cornmeal | 326-349 calories |
| Wheat flour (refined) | 333-353 calories |
| Whole wheat flour | 322-340 calories |
As with grains, Wholemeal flours usually show a slight reduction in calories. compared to refined ones, but the real benefit is in the fiber, which helps maintain satiety and regulate intestinal transit.
In addition, many flour-based preparations incorporate sugars, fats and other caloric ingredients (butter, oils, cheeses, etc.), which significantly increases the energy value of the final product compared to the flour itself.
Cereal bars: more processed, more calories
Cereal bars are sold as a "healthy" snack, but they are often ultra-processed foods and their nutrition labels often show a higher energy content than the grains from which they are made. This is because, to bind them and give them flavor, they are added sugars, syrups, fats or chocolate.
On average, cereal bars fall within a similar or slightly higher range than breakfast cereals, with a contribution that can exceed... 430 kcal per 100 grams in some varieties.
| Cereal bar (100 g) | approximate calories |
| Chocolate cereal bar | 397 Kcal |
| Cereal bar with fruit | 395 Kcal |
| Corn and wheat bar | 431 Kcal |
| Wheat and chocolate bar | 437 Kcal |
In other words, even if the base is cereal, It is not advisable to equate a bar with a bowl of oats or brown riceFor occasional use it's fine, but if you're looking for truly healthy options for everyday life, it's better to go for whole grain cereal or homemade mixes of flakes with fruit and nuts without added sugars.
Legumes: calories, fiber and plant protein
Legumes (lentils, chickpeas, beans, dried peas, soybeans, etc.) are notable for providing complex carbohydrates, a significant amount of plant protein, and plenty of fiberIn terms of energy, its value per 100g raw is comparable to that of many cereals.
According to composition tables used in reports on the nutrition and health of legumes, the average values for the group are around 350-380 kcal per 100 g of dry product, with variations depending on the species and fat content.
| Legume (100 g, raw or dried) | approximate calories |
| Chickpeas, dried (basic table) | 361 Kcal |
| Beans, dried seed | 322-337 calories |
| Lentils, whole dried seed | 350 Kcal |
| Whole, raw dried peas | 304 Kcal |
| Split, raw dried peas | 311 Kcal |
| Soybeans, mature dried seeds | 356-368 calories |
| Raw peanuts with skin | 576 Kcal |
| Dried black beans | 306 Kcal |
| Small Red dried beans | 336 Kcal |
| Dried Great Northern Beans | 326 Kcal |
| Bean, generic dried seed | 290-336 calories |
When these legumes are cooked in water, their moisture content increases and, consequently, its calories per 100g they drop significantlyFor example, boiled split peas contain around 129 kcal per 100 g, and cooked chickpeas contain around 120-130 kcal per 100 g.
In addition to the energy data, the tables show that many legumes contain more than 20% protein in dry weight, with especially high peaks in soybeans, and a large amount of dietary fiber, which makes them great allies to improve the nutritional profile of the diet.
Legumes, cereals and dietary fiber
If your goal is to increase your fiber intake, legumes and whole grains are two of the best options. best assets at your fingertipsAlong with fruits, vegetables, nuts and seeds, they allow you to reach the daily recommendations without too much complication.
The US dietary guidelines, for example, propose a target of 14 grams of fiber per 1.000 kcal consumed daily by people from 2 years of age, and about 19 g per day for children from 12 to 23 months. Translated to a guideline of 2.000 kcal, we would be talking about about 28 g of fiber daily.
To achieve this without noticing the change too much, it's best gradually increase the amount of fiber over several weeks and accompany the process with good hydration, since certain types of fiber absorb water in the intestine and could cause gas or discomfort if increased suddenly.
The dietary fiber tables show that, for example, a serving of boiled lentils (1 cup) It provides around 15,5g of fiber, and a cup of cooked black beans about 15g, very considerable figures when we take into account the overall daily target.
Something similar happens with some whole grains: a cup of cooked whole wheat spaghetti or pearl barley can provide about 6g of fiber, and a cup of cooked oats about 4g, which added to legumes and fruits make it much easier to meet the recommendations.
Examples of fiber-rich foods from cereals and legumes
To put this into practice, it's very helpful to look at typical portion sizes and see how much fiber some everyday foods actually provide. Many of them combine a moderate amount of calories with a great satiating effect thanks to the fiber.
Within the group of cereals and their derivatives, we find several examples that are very useful if you want reinforce the fiber intake without increasing fat intake too much:
| Grain or cereal (cooked portion) | Serving size | Approximate fiber |
| Whole wheat spaghetti | 1 cup (151 g) | 6 g |
| Cooked pearl barley | 1 cup (157 g) | 6 g |
| cooked quinoa | 1 cup (185 g) | 5 g |
| Cooked instant oats | 1 cup (234 g) | 4 g |
| Cooked brown rice | 1 cup (195 g) | 3,5 g |
| Whole wheat bread | 1 slice (32 g) | 2 g |
| Rye bread | 1 slice (32 g) | 2 g |
Regarding legumes, nuts and seeds, the data is even more striking: a cup of split peas or boiled lentils It provides 15-16 g of fiber, and just 28 g of chia seeds add up to about 10 g of fiber, which makes them very interesting for enriching yogurts, smoothies or salads.
In addition, many of these foods not only stand out in fiber, but also provide proteins, minerals such as magnesium or potassium and unsaturated fats in the case of nuts and seeds, making them very complete nutritionally.
How to interpret the calories in grains and legumes according to your goal
With all this information on the table, the big question is how to use it in everyday life to adapt the diet to your personal goalsWanting to gain weight and muscle mass is not the same as wanting to cut body fat, and that determines both the quantities and the type of cereal and legume you want to prioritize.
If you're looking to gain weight in a healthy way, you can rely on cereals that are somewhat higher in calories and denser (oats, wholegrain muesli, whole grain breads, quinoa) combined with legumes, nuts and some olive oil, achieving very energetic and nutritious dishes without resorting to ultra-processed foods.
On the other hand, if your goal is to lose fat, you'll want to focus on whole grains in moderate amountsGiving significant weight to cooked legumes (which, per 100g once hydrated, have far fewer calories than dry), vegetables and sources of lean protein, thus maintaining good satiety with reasonable calorie control.
Counting calories or macros can be a useful strategy, but it's not mandatory. Many people achieve results simply by not counting calories or macros. prioritizing minimally processed foods (whole grains, legumes, fruits, vegetables, quality proteins, healthy fats) and reducing products high in sugars and bad quality fats.
In any case, knowing what energy the different legumes and cereals you use daily provide allows you to to fine-tune the portions much better and choose wisely between very similar options, such as brown rice versus white rice or a legume salad versus a sugary cereal bar.
The calorie and fiber tables for cereals and legumes show that we are talking about foods with a medium-high energy content per 100g raw, but that these become moderate once cooked, while also offering complex carbohydrates, fiber, vegetable proteins and essential micronutrientsIf you combine them with fruits, vegetables, lean proteins and healthy fats, you have practically solved the basis of a balanced diet, whether your goal is to take care of your health or adjust your body weight.
