Abstract
Fats are an important basic nutrient that
participates in the structure of the human
body and enables it to perform its vital
activities. Fats can be taken into the body
with many different foods. Since the oils
taken from different nutrients contain fatty
acids in different concentrations and
properties, their effects on health are also
different. In particular, the effects of
saturated fats and unsaturated fats, which
follow different paths in the body, on health
are a subject that is frequently emphasized.
In addition, the health effects of trans-fats,
whose consumption has increased in recent
years, are also discussed. The effects of
saturated fats on serum cholesterol levels,
the effects of unsaturated fats on brain
development, and the relationship between
fat consumption and obesity have been
studied for years. It is known that
unsaturated fatty acids, especially omega-3
fatty acids, are more beneficial for heart
health, brain development and mental
diseases, whereas some saturated fatty acids
affect body systems negatively by raising
serum cholesterol and causing inflammation
in various ways. On the other hand, while the
consumption of trans-fatty acids continues to increase, various harmful effects are also
emerging. The negative effects of trans-fatty
acids are on heart health, and the need for
arachidonic acid, an essential fatty acid are
increased. In this review study, the
relationship of fatty acids with health has
been examined from many different
perspectives and includes information on the
effects of fatty acids on heart and brain
health, their relationship with obesity and
insulin resistance, and their effects on
longevity.
