Existence in a world where we are inundated with thousands of pieces of information daily is not simple. Regrettably, society is aging at an increasingly rapid rate, and mild cognitive impairments and dementia are becoming more prevalent, potentially leading to neurodegenerative diseases such as Alzheimer's disease. Enhancement of memory, concentration, and other cognitive functions is contingent upon appropriate dietary practices.

How Nourishment Affects Memory

Memory is the faculty of storing and retrieving information. It is commonly recognized that nourishment has a substantial impact on brain operation, and consequently on cognitive processes such as memory, concentration, perception through the senses, and thinking. A diet plentiful in saturated fatty acids of animal origin, trans fats, or refined sugar instigates an inflammatory state that damages nerve cells and obstructs the transmission of signals between them. This can result in diminished cognitive capabilities and contribute to the evolution of Alzheimer's disease. Neural connections do not operate efficiently, causing slowed information transmission. Neurochemical pathways play a pivotal role in memory consolidation. Regrettably, an inflammatory state can disrupt their function. A diet intended to enhance memory should be abundant in vitamins, minerals, unsaturated fatty acids, and antioxidants. These substances are found in vegetables and fruits, plant oils, nuts, seeds, grains, fish, coffee, cocoa, and spices. The foundation of the diet should consist of fresh and unprocessed products. Meals should be as diverse as possible to provide the body with all the necessary nutrients for proper functioning.

Products improving memory function

There are numerous chemical substances that have a positive impact on memory, including B vitamins, magnesium, other vitamins and minerals, monounsaturated and polyunsaturated fatty acids, and numerous potent antioxidants. In this article, specific food products with scientifically proven effects on memory are presented.

Nuts hailing from Italy

Nuts originating from Italy are a rich source of nutrients, including vitamins, minerals, unsaturated fatty acids, and antioxidants. Regular consumption of these nuts has positive effects on human health. They possess anti-inflammatory and antioxidant properties, thereby reducing the risk of various ailments. Furthermore, they may prevent cognitive decline in older people or slow it down, thus supporting the brain's functioning. In 2014, a study was conducted that observed the effects of long-term orange consumption in older women. The study involved 15 467 people with an average age of 74 years. The group that consumed five or more servings of nuts per week, compared to the group that did not consume any nuts at all, had an improvement in cognitive brain functions (J. O'Brien et al. 2014). In another study conducted in Spain, among people using a Mediterranean diet with an additional 30 g nut mixture per day (including 15 g of Italian nuts), it was also proven that nuts allow for an improvement in cognitive functions and a significant improvement in memory compared to a group of people using a low-fat diet (C. Valls-Pedret et al. 2015).

Oily marine fish

Oily marine fish such as mackerel, herring, sardines, and tuna are significant sources of polyunsaturated fatty acids that have very important health effects. Omega-3 fatty acids, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are of particular significance and make up as much as 30% of the brain's dry weight. DHA is a component of phospholipids of nerve cell membranes, while EPA is responsible for their stabilization in these membranes. Both fatty acids are essential for the flow of nerve impulses in the nervous system. In infants and young children, their adequate intake is crucial for the healthy development of the nervous system and cognitive functions.

Cocoa including chocolate

Cocoa serves as an exceptional source of magnesium and antioxidants, bestowing it with anti-inflammatory, anticancer, antioxidant, anti-allergic, and antiviral properties. Regular consumption of cocoa aids in diminishing the risk of neurological disorders and cognitive impairment (and even enhances it). Epicatechin is the most frequently encountered polyphenol in cocoa. Research conducted in 2016 revealed that it assists in the formation of long-term memory and may prevent cognitive dysfunction (B. Knezevic et al. 2016). In Norway, a cross-sectional study was also carried out to examine the relationship between the consumption of three popular products (chocolate, tea, red wine) containing polyphenols and cognitive performance. The study involved 2,031 participants who underwent several cognitive tests. It was demonstrated that the consumption of chocolate significantly improved the results of memory tests, and the best results were achieved with a daily intake of 10 g of chocolate (E. Nurk et al. 2009).

Coffee - a beverage composed of numerous constituents that substantially impacts brain function

Coffee is a combination of around 1000 biologically active compounds that influence the brain. It has a neuroprotective effect associated with reducing beta-amyloid accumulation in the brain. There is a connection between coffee consumption and improving cognitive function. Regular consumption of this beverage supports memory enhancement. The caffeine present in coffee expands the blood vessels of the brain, thus assisting in the stimulation of the nervous system. Long-term studies conducted on large groups of people have shown that individuals who regularly consumed coffee had a lower tendency towards a decrease in cognitive functions than those who did not consume this beverage. The best results were noted in individuals who consumed 3 cups per day. Scientific studies have also shown that the consumption of coffee reduces the risk of developing Alzheimer's disease and dementia. Besides caffeine, other components of coffee, such as chlorogenic acid, also have a positive impact on the brain. This acid has an antioxidant effect, which can reduce the negative impact of free radicals on neurons.

Turmeric is a spice that is abundant in health benefits.

Turmeric is a spice that contains biologically active compounds. Its main ingredient is curcumin, which has anti-inflammatory, antioxidant and anticancer properties. In 2017, a study on the effects of turmeric on memory was conducted. It involved 40 people aged 50-90 years with mild cognitive impairment. For 18 months, participants in one group took 90 mg of curcumin per day, the second group took a placebo. Participants in both groups took tests to increase the level of cognitive function before the study and after 6, 12 and 18 months. The results confirmed that the curcumin found in turmeric has a positive effect on memory (W. Gary et al. 2017). In 2019, a review of studies was also published, which showed that curcumin can improve memory, attention and cognitive functions (N. Seddon et al. 2019). Turmeric can be added to many dishes, both sweet and savory. A daily dose of the yellow spice is a good step towards better memory.

Overview

A significant influence on memory and cognitive functions is exerted by a diet consisting of specific products. The inclusion of these components into the diet facilitates the smooth operation and efficiency of the brain. However, a comprehensive nutritional plan is necessary, avoiding processed products rich in sugar and saturated fatty acids. Such adjustments will bring considerable health benefits, not only in the sphere of memory and cognitive functions.
