The largest ever trial of fish oil supplements has found no evidence that they offer benefits for cognitive function in older people.
The OPAL study investigated the effects of taking omega-3 long-chain polyunsaturated fatty acid supplements over a two year period on the cognitive function of participants aged 70-80 years.
The number of people with cognitive impairment is rising and it is estimated that by 2040, more than 81 million people globally will have dementia.
So much for fish oil, it seems like more and more evidence is piling on showing that fish oil doesn't help a lot with age-related diseases like cancer and dementia.
Fish oil is commonly recommended by a lot of people in the worldwide health business against autism, cancer, heart disease, alzheimers etc.
However one may start wondering if it really is anything to spend your own (or your aging relatives) money on.
