A new study from China suggests that higher consumption of fish, rich in omega-3 fatty acids, may be associated with a slower decline in composite and verbal memory scores in older adults.
The cohort study conducted a dietary survey among 1566 adults 55 years or older and measured their cognitive performance during a mean of 5 years (1). The study results showed that participants aged 65 or older who consumed at least one serving fish per week had a significantly reduced rate of cognitive decline compared to those who ate less than one serving a week. These findings were independent of a wide array of other dietary and non-dietary factors (e.g., physical activity).
The researchers commented that although evidence remains limited, several mechanisms linking nutrients such as omega-3 fatty acids in fish to cognitive health were proposed (2). However, because fish is rich in other nutrients that may benefit cognitive function, such as magnesium, selenium, vitamin D, and several B vitamins, the interplay of a number of nutrients in fish may be responsible for the health benefits of fish consumption (3). The findings of earlier research suggest that any benefits of fish consumption for delayed cognitive decline may be limited to specific population subgroups (e.g., older adults) or specific types of fish (4).

Excessive intake of high-energy macronutrients and their potential consequences for people’s health are a problem in many industrial nations. In the case of micronutrients, however, epidemiological data suggests that over-supply is the exception rather than the rule across the globe. Many people are therefore concerned that their dietary habits are failing to provide them with a sufficient supply of essential nutrients such as vitamins and carotenoids. Given that intakes of some nutrients are below officially recommended levels, it might at first sight appear unnecessary to set upper intake levels for micronutrients. However excessive intake of food supplements and fortified foods in addition to normal diets could conceivably lead to intake levels which could potentially be considered harmful. It may be sensible to define an upper daily intake level at which the risk of adverse effects on health is unlikely, particularly in the case of fat-soluble vitamins which are stored in small quantities in the body.
