Goodbye to myths—experts reveal why eating these three foods several times a week can boost your memory, protect your heart, and extend your life

The saying that health enters through the mouth couldn’t be more true. There are certain foods that can be much more beneficial to our body than others, that’s a fact. Apparently, according to studies, eggs, nuts, and legumes are the three superfoods with the best nutritional quality, scientific evidence, and they’re also easy to find. Let’s keep in mind that mental health and diet are linked in the same way as the brain and the gut, in a relationship that has important consequences for the body.

Not being healthy contributes to the development of anxiety, inattention, and illnesses such as depression

According to scientific data, an unhealthy diet causes the intestines to become inflamed and suffer the consequences of poor nutrition. This contributes to the development of anxiety, inattention, and illnesses such as depression. Expert Manuel Viso explains the bioactive compounds in these three superfoods and how they help improve brain health and prevent cardiovascular disease due to their high nutritional profile.

The term “superfood” refers to those with a high nutritional profile

According to exact data, between 90% and 95% of serotonin, a neurotransmitter related to appetite regulation and other functions, is produced in the gut. Therefore, proper food utilization is essential for complete and healthy health. On the one hand, in Viso’s experience, the term “superfood” refers to those with a high nutritional profile and supported by scientific research on their nutritional and functional benefits for improving certain health conditions.

Eggs: “Proteins of extremely high biological value, super-complete in amino acids”

With this clear, we can start with the egg. The properties of this food are well known: it boosts the brain and body with the most complete protein. According to the expert, eggs contain “proteins of extremely high biological value, super-complete in amino acids, such as choline for your brain, antioxidants for your vision, vitamin D, iron, and healthy fats.” Eggs are already among the foods commonly found in every kitchen, so consuming them or adding them to our diet can be done easily.

The anti-inflammatory and antioxidant effects of the omega-3 fatty acids in walnuts improve thinking and memory

Let’s focus on natural nuts, in this case, walnuts. According to experts, they’re the snack that takes care of the heart and strengthens the mind. The anti-inflammatory and antioxidant effects of the omega-3 fatty acids in walnuts are very promising for improving thinking and memory. The two omega-3s that protect the brain and heart are antioxidants and anti-inflammatories, explains the expert. Walnuts contain healthy fats and oils that our brain needs to function well, along with essential vitamins and minerals, such as the selenium in Brazil nuts.

Including these types of carbohydrates in your diet is very important, as they provide energy without sugar spikes

Last but not least, legumes. A complete, inexpensive superfood widely used in recipes around the world. According to Viso, legumes are rich in “plant-based protein, a virtually complete protein, lots of fiber, iron, and zinc.” We can include legumes as a complement to a main course or as the main ingredient in a dish, such as a chickpea salad, for example. Legumes contain B vitamins and slow-absorbing carbohydrates. Including these types of carbohydrates in your diet is very important, as they provide energy without sugar spikes.

We can also include avocados, dark chocolate, or chard in our diet. These foods have enormous properties, and when consumed in the right amounts, they can be very beneficial for our health. In any case, before following expert recommendations via social media or the internet, it’s always advisable to consult your primary care physician to ensure that what you’re consuming won’t have negative consequences.
