Insulin resistance in lacto-ovo-vegetarians vs omnivores

[Guest guest]

Hi All,

It seems that lacto-ovo-vegetarians have better insulin resistance than

omnivores.

Note the Table 2 age effect in omnivores only of insulin resistance values IR

(HOMA). The oats and especially barley values for intake were highly different.

The pdf of the 3-page including references paper are available.

posted the Medline citation and abstract on the Main CR Society list.

.... Randomly selected group of vegetarians consisted of 95

apparently healthy adult normal-weight long-term

lacto-ovo-vegetarians, who consumed plant food, dairy

products and eggs.A control group of 107 apparently

healthy normal-weight non-vegetarians (general popu-

lation) consumed a traditional western diet.The group

characteristics are presented in Table 1.
