Omega-3 deficiency as harmful as smoking, new study finds
A lack of appropriate nutrients can lead to various health problems, among which omega-3 fatty acids are particularly important. Recent research indicates that a deficiency in these acids affects our health as negatively as smoking cigarettes.

Regular consumption of omega-3 fatty acids has a positive impact on the cardiovascular system, helps reduce cholesterol levels, supports weight loss, enhances memory and concentration, and strengthens the skin, hair, and nails. Therefore, it is an essential component for the proper functioning of the body.
Consuming omega-3 fatty acids is particularly important for seniors. An adequate supply can considerably reduce the risk of Alzheimer's disease.
Omega-3 fatty acids may also reduce the risk of atherosclerosis, heart attack, and stroke. Research published in the "American Journal of Clinical Nutrition" has shown that a deficiency of these acids can affect our health as negatively as smoking cigarettes, which is undoubtedly surprising. These findings are the work of experts from the Framingham Heart Study in the USA, who analysed the lifespan of Americans and Japanese over seven years.
The study leaves no doubt: a lack of omega-3 fatty acids is a significant problem
The study involved 2,500 people aged 66 to 73. It found that Japanese individuals with omega-3 levels exceeding 8% lived an average of five years longer than Americans, whose levels were around 5%. Researchers in the USA warn that a lack of polyunsaturated omega-3 fatty acids in the diet can lead to serious cardiovascular diseases and increase the risk of premature death. The difference can be as much as several years.
"Being a current smoker (at age 65) is predicted to subtract more than four years of life (compared with not smoking), a life shortening equivalent to having a low vs. a high Omega-3 Index," commented Dr. Michael McBurney from the research team.
A diet low in omega-3 fatty acids burdens the cardiovascular system and weakens the immune system, increasing susceptibility to infections and cancer. Omega-3 deficiency can contribute to fatigue, memory and concentration problems, dry skin, and brittle hair. To replenish omega-3 levels in the diet, consuming fatty sea fish, soybean oil, corn oil, rapeseed oil, olive oil, flaxseeds, chia seeds, and avocados is beneficial. These products will quickly boost the levels of these acids in our bodies.
