Ravintorasvan kokoomus saattaisi omata vaikutusta verenpaineeseen ja on mahdollista, että hyvin vähäinen omega3- PUFA rasvahappojen saanti kohottaa verenpainetta. Kuitenkaan verenpaine ei vaikutu (enemmästä) PUFA:n saannista, jos saanti jo kattaa minimitarpeet.-
Dietary fat composition might influence blood pressure,
and it is possible that very low intake of n-3 PUFA increases blood
pressure. However, at intakes exceeding the minimum requirement,
blood pressure is not affected by PUFA intake.

In comparison of cis-MUFA and SFA, diets rich in
cis-MUFA have resulted in lower blood pressure in some studies.
Recently, a prospective randomized intervention found lower blood
pressure among those with lower intake of SFA from infancy. The
amount of fat might play a role in the effect of changing the
quality of dietary fat on blood pressure. In one study with a high
intake of fat (about 40E%), no difference between MUFA and SFA was
found. And in another study the beneficial effect of MUFA was more
pronounced in those subjects with a fat intake below 37E%.

Fish oil supplement has been observed to give varying
results. In randomized trials, it decreased blood pressure in young
overweight adults. in infants, and in adolescents. A recent
observation found lower blood pressure among elderly people taking
fish oil supplements, but such intake was found to increase blood
pressure in pregnant women and decrease the size at birth of the
babies.

The SR of Schwab et aliae concluded that the evidence
for an effect of any modification of the quality of dietary fat on
blood pressure was limited - no conclusion.
