A July 2021 study by the Hospital del Mar Medical Research Institute (IMIM), in collaboration with The Fatty Acid Research Institute in the United States and several universities in the United States and Canada, said that
"Having higher levels of these [Omega-3] acids in the blood, as a result of regularly including oily fish in the diet, increases life expectancy by almost five years",
"Being a regular smoker takes 4.7 years off your life expectancy, the same as you gain if you have high levels of omega-3 acids in your blood”.
"This reaffirms what we have been seeing lately … not all saturated fatty acids are necessarily bad.”
"What we have found is not insignificant. It reinforces the idea that small changes in diet in the right direction can have a much more powerful effect than we think, and it is never too late or too early to make these changes"
