Why integrate Omega 3 at 60 years old?
As we age, health risks increase, and protecting the heart, brain, and joints becomes a priority from the age of 60 onwards. Omega-3s can help fight the inflammation common to typical diseases of old age, and beyond. Let's discover together all the potential of these precious fats and why supplementing the diet with adequate forms and quantities is important.
Aging is a universal, gradual, and irreversible biological process that involves a progressive decline in the functions of all cells, tissues, and organs in our body.
Although modern medicine, with its advances, has significantly extended our life expectancy, aging brings with it a significant increase in the risk of developing various chronic diseases, which become the main causes of disability and mortality among the elderly.
In particular, after the age of 60, it is common to face multiple simultaneous illnesses, which makes managing our health and promoting our psycho-physical well-being more complex.
Among the most common problems in old age are cardiovascular diseases (such as heart failure and atherosclerosis) and metabolic diseases, primarily type 2 diabetes, the incidence of which rapidly increases after this age.
Concurrently, the musculoskeletal system undergoes deterioration, often manifesting as joint problems, such as osteoarthritis (often also called degenerative joint disease), which is the leading cause of disability in those over 60.
No less critical is cognitive decline: from age 65, the prevalence of neurodegenerative diseases like Alzheimer's doubles every five years, drastically affecting an individual's independence.
Understanding how to counteract these processes is fundamental for promoting healthy aging.
Omega-3s and inflammation: the common thread of aging
Many aging-related diseases share a common biological mechanism: chronic low-grade inflammation. In the context of aging, this silent but detrimental form of inflammation even has a specific name: inflammaging.
As we age, senescent cells accumulate in tissues and begin to produce a range of pro-inflammatory molecules that damage surrounding healthy cells and fuel a persistent inflammatory state.
In this context, Omega-3s are considered anti-inflammatory nutrients par excellence. Our body uses these fatty acids to produce regulatory molecules called eicosanoids; while those derived from Omega-6s (very abundant in the modern diet) tend to promote inflammation, eicosanoids derived from Omega-3s have the opposite effect. Furthermore, Omega-3s give rise to specialized molecules such as resolvins, protectins, and maresins, which have the crucial task of actively shutting down the inflammatory response once its defensive function has been exhausted.
An adequate intake of Omega-3s therefore helps balance the excess of Omega-6s, reducing the activation of key inflammatory factors and protecting the body from the tendency to accelerate cellular damage typical of aging.
But their health benefits after age 60 do not end there. In fact, there is ample evidence of their specific ability to protect us from various health problems associated with aging.
Omega-3s against cardiovascular diseases and diabetes
One of the primary benefits of Omega-3s, particularly useful after the age of 60, is heart protection. For those over 60, maintaining circulatory health is a priority, as age is an independent risk factor for heart failure, and the increased risk of cardiovascular events is common in older age.
The European Food Safety Authority (EFSA) has confirmed that the Omega-3 fatty acids EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) contribute to normal heart function and the maintenance of normal blood pressure and triglyceride levels. Significant clinical studies, such as REDUCE-IT, have shown that EPA supplementation can significantly reduce the risk of major cardiovascular events in high-risk individuals.
In the case of diabetes, a condition that drastically increases the danger of deaths from vascular causes, research suggests that Omega-3s can offer supplementary protection. The ASCEND study, conducted on over 15,000 diabetic patients, found a lower incidence of deaths from vascular causes among those who supplemented with these beneficial fats. However, science suggests that targeted dosages and a balanced EPA/DHA ratio are necessary to achieve significant benefits on triglycerides and blood lipid alterations associated with diabetes, emphasizing the importance of informed supplementation under professional guidance.
Omega-3s for joint health
Other easy targets of aging are the joints. In particular, osteoarthritis affects over 10 million people in Italy and is a heavy burden on the quality of life of the elderly.
Joint problems are not just a matter of mechanical wear and tear, but are closely linked to inflammation of the cartilage and associated structures. Given their anti-inflammatory role, it should not be surprising that Omega-3s have also proven to be valuable allies in this field.
Recent research suggests that these fats can influence the progression of osteoarthritis, reducing the degeneration of joint cartilage precisely due to their anti-inflammatory properties. Confirmation comes from a meta-analysis of data in scientific literature, according to which Omega-3 supplementation helps alleviate pain and improve the functionality of joints affected by osteoarthritis.
Furthermore, there is an inverse association between the consumption of these nutrients and the prevalence of joint disorders: those who consume more tend to have fewer problems. Supplementing with Omega-3s at age 60 therefore means providing the body's "gears" with the necessary support to maintain mobility and reduce reliance on painkillers.
Omega-3s and psychological well-being in older age
Moving from the physical to the psychological sphere, it is interesting to remember that the brain is largely composed of fats and how fundamental DHA is for maintaining its normal functions.
With aging, the risk of cognitive decline and dementia increases, but it seems that Omega-3s can play a protective role by slowing down the deterioration of cerebral white matter and the loss of neuron integrity.
Particularly interesting is the role of Omega-3s in preventing Alzheimer's, especially for those with a genetic predisposition due to carrying the APOE*E4 gene. Recent studies have shown that supplementing with fish oil rich in EPA and DHA can reduce brain cell damage in these individuals after just one year of intake.
But it doesn't stop there, because Omega-3s have also been associated with benefits against depression in older age, a condition that unfortunately tends to be underestimated and is linked to cerebral inflammatory processes. Maintaining high levels of these fatty acids in the blood is therefore an essential strategy to preserve not only memory but also overall psychological balance.
Omega-3s and longevity
A vast meta-analysis published in Nature Communications revealed that the risk of all-cause mortality is significantly lower in people with the highest levels of Omega-3s in their blood. Specifically, those characterized by the highest blood concentrations among those measured had a 15-18% lower risk of death compared to those with the lowest levels.
At a molecular level, Omega-3s seem to act as a true elixir of long life by slowing down the biological clock. In fact, studies suggest a protective effect on telomeres, the ends of chromosomes that shorten with aging. Furthermore, Omega-3 intake has been associated with slowing biological aging as measured by DNA methylation, a modification that affects the functioning of our genes without altering their sequence.
These data support the hypothesis that regular intake of Omega-3 supplements can slow down degenerative processes at the cellular level, promoting healthy longevity.
Why take Omega-3 supplements: the choice of EPA and DHA
Although the main dietary source of Omega-3s is fatty fish (such as salmon, mackerel, sardines, and anchovies), achieving the necessary doses for preventive or therapeutic purposes through diet alone can be difficult. For example, to control triglycerides or combat hypertension, EFSA recommends dosages of 2-3 grams per day of EPA+DHA, quantities difficult to achieve without daily and massive fish consumption.
Moreover, many choose plant sources such as walnuts or flax seeds, which contain alpha-linolenic acid (ALA). However, our body is inefficient at converting ALA into EPA and DHA, which are the biologically active forms responsible for most of the protective effects described. Furthermore, this poor conversion is further hampered by the excess of Omega-6s typical of modern diets.
For this reason, especially from the age of 60, when the body's needs increase, dietary supplements based on marine oils (fish, krill or microalgae) represent a valid and safe aid. These supplements directly provide concentrated and purified doses of EPA and DHA, effectively supporting the heart, brain, and joints even in cases of allergies or dietary choices that exclude fish.
