Scientific research indicates that caffeine improves basic cognitive functions such as attention, vigilance, and response time. At the same time, however, in addition to its benefits, caffeine can cause a number of problems, particularly among those who feel tired or weak. Too much caffeine leads to perceived anxiety and sleep problems, which are factors limiting brain work. Caffeine has not been proven to support key brain functions beyond focus or creativity. Some studies suggest that caffeine intake may inhibit the absorption of vitamins.
Consumers are increasingly aware of the impact of sleep on health and wellbeing. Sleep is an essential element of mental and physical health and the quality of sleep has a significant impact on mood and mental wellbeing. Research shows that one-third or even half of patients with chronic sleep problems have mood disorders. Consumers also point to the connection between caffeine and poorer sleep quality.
The trend of increasing the share of plant products in food purchases is becoming more and more visible in many markets. Although the group of consumers who define themselves as vegans is not large, other consumers are eager to use vegan or vegetarian products to diversify and enrich their diet. There is an increased demand from consumers for healthier, plant-based products. Hot beverage manufacturers increasingly use the “vegan” label on their products.
For consumers, the naturalness of food is an increasingly important factor in their choice of food.
Dietary fibre and its health functions are increasingly important for consumers and attention is being drawn to the link between well-being and the type of food consumed. This is reflected in scientific studies describing the system of the gut-brain axis and the correlation between the digestion process, and the functions of the brain and its development. Fibre-rich products support the health of the bowel and can contribute to improving wellbeing.
