The correct answer is healthy fats, which play a significant role in supporting cognitive function in older adults. Healthy fats, such as those found in fish (like omega-3 fatty acids), avocados, nuts, and olive oil, are important for brain health. These fats help maintain the structure and function of brain cell membranes and may enhance cognitive performance and reduce the risk of cognitive decline as people age.

Research indicates that diets rich in healthy fats can improve memory and overall brain function. Omega-3 fatty acids, in particular, have been linked to various health benefits, including anti-inflammatory effects and the promotion of neurogenesis, which is the growth of new neurons vital for cognitive processes.

In contrast, high sugar intake, processed foods, and high sodium intake have been associated with negative impacts on cognitive health. High sugar consumption can lead to insulin resistance and inflammation, both of which can impair cognitive function. Processed foods often contain unhealthy trans fats and additives that can also affect brain health adversely. High sodium intake is linked to hypertension and can have detrimental effects on overall cardiovascular health, which in turn can affect cognitive function. Therefore, the role of healthy fats as a dietary factor is key in promoting and improving cognitive functioning in older adults.
