Most people across the world are not
getting enough omega-3, leaving a major gap between scientific recommendations
and daily diets, according to a study. The three main forms of omega-3
are alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and
docosahexaenoic acid (DHA). Researchers lay stress on the critical role
of EPA and DHA across all stages of life and point out that food alone often
can’t meet needs and the challenges involved in reaching healthy intake levels.
It highlights the need for clearer global
guidelines and easier access to sustainable mega-3 sources.
Researchers found that the intake and
recommended levels varied in a big way. They inferred that the gap could be
closed through sustainable ways to get these important nutrients — like foods
enriched with omega-3s or supplements. These changes could help more people
enjoy the health benefits linked to higher intakes.
Omega-3s play a vital role in health and
people should meet the required levels through food or supplementation,
especially in pregnancy and those with low fish intakes.
The study was done on healthy populations
to understand the required level of omega 3 and to see whether people were
meeting it.
Omega-3 consumption supports a healthy
lifestyle throughout all stages of life — from reducing the chance of pre-term
birth and supporting visual and cognitive development in infants, right through
to improving cardiovascular health and immune function. It is also associated
with reduced risk of depression and cognitive decline, including Alzheimer’s
disease.
The study found that the most frequently
recommended intake for adults is 250 mg per day of combined EPA and DHA, with
an additional 100-200 mg of DHA advised for pregnant women. These targets can
be achieved by eating more oily fish, such as salmon or mackerel, or through supplementation
where needed.
The paper also identified challenges that
different populations have in achieving current omega-3 recommendations, such
as difficulties in meeting oily fish recommendations due to low seafood
consumption, or sustainability concerns, as well as some populations having
limited access to supplementation advice.
