MILK
PROVIDES UNIQUE BENEFITS IN VITAMIN E ENRICHMENTS OF PLASMA LIPIDS
 Saturated
fat found in dairy products may contribute to cardiovascular disease (CVD) risk,
while vitamin E, a lipid antioxidant, may have a protective affect against CVD.
In research published in the American
Journal of Clinical Nutrition, Hayes et al. studied the potential of vitamin
E to offset the potential CVD risk effects of milk fat by adding the vitamin to
milk at different dosage levels, in different forms, and through different
dispersion methods. In comparison to other forms of vitamin E delivery, milk had
an enhanced ability to transport vitamin E to plasma lipoproteins.
The
researchers conducted three experiments over 10 weeks, in which the 48
participants consumed milk that had been fortified with different combinations
of vitamins A and D, and lower (30 mg.) or higher doses (100 mg or 200 mg) of
vitamin E. Orange juice and vitamin E capsules were also tested as alternative
forms of delivery. The addition of vitamins A and D to the milk had no effect on
the transfer of vitamin E to plasma lipids, and orange juice was considerably
less effective than milk for transport. Milk was uniquely superior for transport
of vitamin E at higher, but not lower, dosage levels. When microdispersed in
milk, the vitamin was delivered to plasma lipids at more than twice the rate as
that from vitamin E capsules. After 4 weeks of consuming two glasses of 1% fat
milk blended with 200 mg vitamin E per day, the subjects had a 9% drop in total
cholesterol and a 10.7% drop in LDL cholesterol concentrations.
Fortification
of milk with vitamins A and D is already widely practiced and acknowledged as
providing health benefits, and the authors suggest that additional fortification
of milk with vitamin E is warranted due to milk’s enhanced ability to
transport this vitamin to plasma lipoproteins.
