What are the myths about brain-healthy foods?

Some foods get a reputation for being healthy thanks to dubious recommendations that can be found on the internet, or because of oral traditions passed down from generation to generation. However, do these foods really deliver the expected health benefits?

Glucose is a key source of energy for brain function, making chocolate an appealing choice during times of stress and fatigue. However, dietitian and nutritionist Eleonora Ovchinnikova emphasizes that the energy boost from sweets quickly fades: "Chocolates will 'quench' us," she warns. Instead of chocolate, it's better to choose foods with a more stable energy source, such as nuts or fruits, which will provide a longer feeling of fullness and maintain concentration.

Glucose is present in all carbohydrates, but its absorption by the body depends on the type of carbohydrate—fast or slow. Fast carbohydrates, such as sweets, cause a sharp spike in blood glucose and insulin levels, leading to a short-term feeling of energy. Soon after, glucose levels drop, and the person experiences fatigue. Understanding these processes is important for managing energy levels and maintaining health. Choosing the right carbohydrates can help avoid sharp fluctuations in blood sugar and improve overall well-being.

Slow-release carbohydrates play a key role in maintaining stable blood glucose levels. This allows the body to use glucose more efficiently, providing the necessary energy for brain function rather than causing sharp fluctuations in energy. To maintain energy, it is preferable to include whole grains in the diet rather than sweets such as candy and chocolate bars. However, dark chocolate can serve as a compromise: it contains a minimal amount of sugar and is rich in nutrients.

The caffeine in coffee provides only a temporary boost of energy, making its effect short-lived. Students studying for exams at night often find that one cup of coffee is not enough. To maintain concentration and wakefulness, they must constantly increase their coffee consumption, which can lead to undesirable consequences. The right approach to preparation includes not only drinking coffee but also balancing time between rest and study.

Coffee can be a temporary solution in situations where there are no alternatives. However, relying solely on it without proper nutrition is like trying to force a tired horse to run: you can urge it on, but it will eventually exhaust itself and collapse. Our brain is like this horse, and coffee acts as a stimulant. We activate the nervous system and continue to stay awake, while our body cannot recover because it lacks the resources to do so. A proper diet is essential for maintaining energy and brain function, making it more efficient and resilient in the long term. Maintaining consistent strength and alertness requires proper nutrition. A night spent gorging on coffee and chocolate may help prepare for one exam, but afterward, the student will return home and collapse into bed, drained of energy. This will make studying for the next exam significantly more difficult. Proper nutrition promotes not only physical endurance but also mental alertness, which is especially important for students during exam periods. Eating a balanced diet rich in vitamins and minerals helps maintain high energy and concentration levels.

Immediately before an exam, many students try to memorize material in a short period of time. However, this "memory-based" learning often leads to the information being quickly forgotten. This occurs due to several factors. First, when we study material in a rush, we don't have time to deeply understand and absorb it. Memory works better when information is processed consciously and thoughtfully. Second, stress and anxiety associated with an upcoming exam can negatively impact memorization. These factors interfere with concentration and make learning more difficult. Therefore, to ensure long-term retention, it's important to devote time to systematic study of the material rather than relying on short-term memorization.

There are often mentions of foods that promote brain function online. Among the most well-known of these are nuts, berries, vegetables, and fruits. Indeed, these foods are rich in nutrients that can positively impact cognitive function. Regular consumption of such foods can help improve memory, concentration, and overall mental alertness. Adding a variety of vitamins and antioxidants to your diet can help maintain brain health and improve its performance. Supporting mental performance requires a comprehensive approach. If a person doesn't eat a regular and balanced diet, even the healthiest foods won't have a significant impact, including on learning. It's important to include foods containing healthy fats in your diet. For example, fatty fish such as salmon, halibut, and herring, as well as butter, can significantly improve cognitive function, especially during times of stress, such as exams. However, don't expect instant results—eating carrots won't instantly make you smarter. This is just a myth perpetuated by marketing. Proper nutrition should be a constant part of your life, not a short-term solution. Breakfast cereals are truly beneficial for retaining information in classes and lectures. This is the opinion not only of grandmothers and mothers, but also of nutritionists and doctors, who have emphasized their importance in the diet. However, modern research shows that porridge consists primarily of carbohydrates, even slow-release ones. While it's filling, the effect doesn't last long, and hunger may return within a few hours. This can negatively impact concentration and attention, especially during study sessions. Therefore, it's worth considering adding protein and fat to your morning diet to ensure a longer feeling of fullness and improve concentration in class.

Breakfast has become the most important meal of the day, and it's important to prioritize its quality. A proper breakfast should be not only filling but also nutritious. Satiety isn't determined by the volume of food, but by the nutritional density of the foods we choose. Experts emphasize that to achieve optimal health, it's essential to focus on a balanced and varied breakfast. Make sure your morning meal includes protein sources, healthy fats, and fiber to provide energy throughout the day.

Breakfast should include protein and healthy fats to ensure long-lasting satiety. Good options include scrambled eggs, cottage cheese, syrniki, or a whole-grain sandwich with butter or pâté. Including vegetables in your breakfast is also beneficial, as it not only helps you feel full but also improves your overall health. A proper breakfast will help prevent hunger pangs for a long time. Porridge is a healthy dish worth including in your diet, but it's important to choose the right ingredients. Choose whole grains, which require long cooking times, rather than packaged varieties that can be quickly boiled. Whole grains contain essential carbohydrates, which are beneficial for the body. Breakfast, based on such cereals, remains an important part of the diet throughout the day, providing energy and nutrients.

Proper nutrition is an approach to diet that helps improve health and maintain optimal weight. It is based on a balanced consumption of various food groups that provide the body with essential nutrients. The main principles of proper nutrition include food variety, moderation in portions, regularity of meals, and a preference for fresh and natural ingredients.

The main focus should be on vegetables, fruits, whole grains, lean meat, fish, and dairy products. It is important to limit the consumption of sugar, salt, and saturated fats. It is also important to consider the individual needs of the body and the level of physical activity. Proper nutrition helps not only maintain health, but also prevent various diseases, improve overall well-being, and increase vitality.

Why do you crave fast food when preparing for exams?

Fast food can only provide temporary satiety, but does not provide the body with the necessary energy and nutrients for proper brain function. The craving for unhealthy food during a study session may indicate high levels of stress, which in turn has a negative impact on cognitive function. To maintain mental alertness and reduce stress, it is important to choose healthy and balanced foods that promote concentration and memory. Proper nutrition plays a key role in enhancing productivity and well-being during study sessions.

A study conducted at a Korean college found a link between students' stress levels and their eating habits. Students with high levels of anxiety were more likely to consume sweets, fast food, and foods rich in fast carbohydrates, such as potatoes. Overall, students with increased anxiety exhibited two opposing eating patterns: they either overindulged in unhealthy food or completely refused to eat. These findings highlight the importance of stress management in maintaining healthy eating habits among students.

A 2017 study conducted at Ghent University in Belgium found that students struggle to maintain their normal diet during exam periods. They begin to consume snacks such as chips, crackers, chocolate bars, and cookies more frequently. Similar results were found in a recent survey conducted at a university in Saudi Arabia. The study found that as stress levels increased, students' diets deteriorated, with them choosing quick snacks over healthier options. These findings highlight the importance of proper nutrition under stress and the need to develop strategies for maintaining a healthy diet during academic pressures.

It's recommended to swap out a hamburger and fries for a full lunch. Pair it with a walk and meditation to reduce cravings for unhealthy foods. This recommendation is especially relevant for women. Research shows that they are more likely to engage in stress eating and consume unhealthy foods than men. Proper nutrition and an active lifestyle will not only help improve physical health but also cope with emotional distress.

Is fasting beneficial during exams?

Before an exam, there is often not enough time for a proper snack, difficulties preparing food, or loss of appetite due to nervous tension. Some claim that it is easier to concentrate on an empty stomach, but this is a misconception. In fact, proper nutrition plays a key role in concentration and cognitive performance. Even a small snack can help improve memory and attention, which is especially important in stressful situations such as exams. Therefore, it is worth taking the time to prepare light and nutritious snacks to maintain energy levels and provide the brain with the necessary nutrients.

Research conducted by scientists from Utrecht University has shown that hunger can affect our emotional state and improve the quality of decision-making. The participants in the experiments were students in a state of hunger. The results of these studies open new horizons in understanding the relationship between physiological needs and cognitive processes, highlighting that hunger can play an important role in decision-making. Fasting is not beneficial for the body. It is definitely not recommended, as a lack of food can negatively impact brain function. Eleonora Ovchinnikova emphasizes that without adequate nutrition, the brain cannot function effectively. Completing complex tasks can trigger feelings of hunger. Research shows that this is due to changes in blood glucose levels, which can lead to false hunger signals. After a difficult exam, many people experience a strong desire for a tasty and filling snack. Understanding this mechanism can help you better manage your eating habits and avoid excess calorie consumption during stressful times.

A 2016 study by researchers at the University of Alabama at Birmingham (USA) found that it's best to avoid sudden snacking unless you've skipped several meals, as hunger is natural in these situations. Instead of eating, taking a break or doing some light exercise is recommended. This will help curb your appetite and reduce the desire to eat a lot of high-calorie foods, such as pancakes.

Anxiety and stress have a significant impact on exam results. These emotional states can lead to decreased concentration, impaired memory, and difficulty solving problems. During an exam, stress can trigger physical reactions such as increased heart rate and sweating, further distracting and interfering with concentration.

Scientific research shows that moderate levels of anxiety can even promote better performance, but excessive stress often leads to negative consequences. Students who suffer from high levels of anxiety may have difficulty managing time and stress during an exam, which ultimately affects their grades.

To successfully manage anxiety and stress, it is important to employ relaxation techniques such as deep breathing, meditation, and physical activity. Exam preparation also plays a key role in reducing stress levels. The better prepared a student is, the less likely they are to experience anxiety during the exam. Using effective preparation and emotional management strategies can significantly increase your chances of passing an exam.

So what should you eat to study well?

Eleonora Ovchinnikova emphasizes that there are no foods that can instantly improve brain function. Instead, there is a simple principle that helps maintain its effectiveness. Proper nutrition should become a constant habit. If a student prepares for classes in advance, they will not have to strain themselves the day before, memorizing difficult lectures under stress. Regularly following healthy eating principles helps the body cope with intellectual stress and stressful situations. What foods promote good brain function?

To achieve this goal, three key aspects must be considered.

Food is only one part of successful nutrition. Meal planning is also crucial. Following the well-known formula, "Eat breakfast yourself, share lunch with a friend, and give dinner to your enemy," one can understand that each meal has its own significance. Proper distribution of food throughout the day helps improve metabolism and maintain energy. Breakfast helps recharge, lunch is essential for replenishing strength, and dinner should be light to avoid overloading the body before bed. Proper nutrition can significantly impact overall well-being and health.

Here are some tips from an expert:

• Breakfast. We've already explained that it should be filling for students and schoolchildren. The main thing is to absolutely not skip it!
• Lunch. Whatever you choose for lunch, it should also contain protein—for example, fish, meat, chicken, or dairy products. For a side dish, you should eat buckwheat, whole-grain pasta—in general, something that contains "slow" carbohydrates. It's best to think about lunch the day before: will there be a place where you plan to eat tasty, filling, and healthy food? If not, it's worth preparing something in advance and taking it with you. These questions will help you avoid the temptation to "buy off" hunger with fast food.
• Dinner. The key to dinner is not to overdo it, and also not to eat right before bed. Vegetables and dairy products are excellent choices for this meal, as are foods containing light protein. For example, fish or poultry are easily digestible, as are ground meat dishes such as cutlets or meatballs.

When planning healthy snacks, it's important to keep them nutritious and easy to transport. Nuts, which are an excellent source of healthy fats and protein, are recommended. Whole-grain or protein cookies are also good choices, as they will help maintain energy levels throughout the day. Crisps are another good option, as they are light and filling. Don't forget about fruits, such as bananas or apples, which are easy to take with you and are rich in vitamins and fiber. Choosing the right snacks will help you stay healthy and alert throughout the day. Eleonora Ovchinnikova shared with us the recipe for the perfect sandwich, a great snack for schoolchildren and students. This simple and delicious recipe will quickly satisfy your hunger and give you energy for studying. To prepare, you'll need fresh bread or crispbread, lean meat or chicken, fresh vegetables such as tomatoes and cucumbers, and herbs to taste. Spread butter or spread on the bread, add meat, chopped vegetables, and herbs. This sandwich is not only delicious but also healthy, providing essential vitamins and minerals. It's perfect for snacking between classes or on walks.

Try this recipe, and your day will become brighter and more fulfilling.

• Base: For the base, use whole-grain bread or thin Armenian lavash if you want something like shawarma.
• Sauce: Mix sour cream and a crushed clove of garlic, add finely chopped herbs to taste, salt and pepper.
• Filling: boiled chicken or meat / fried fish - foods high in protein or healthy fat; vegetables - for example, cabbage, green salad, tomatoes, carrots, cucumbers.

This sandwich helps maintain brain activity and overall energy levels, but it cannot completely replace a full breakfast and lunch.

To maintain brain health, it is important to take care of your nutrition in advance. You should not wait until the last minute to saturate your body with the necessary nutrients. You should plan your diet in advance - preferably six months before important exams. Simply put, proper nutrition should become a regular habit. Eleonora Ovchinnikova emphasizes that a regular and balanced diet contributes to improved cognitive function and overall performance.
