Standard-fat diet (SF) vs. moderately high-fat diet (mHF);
SF vs. mHF with betaine added to drinking water (mHFB);
mHF vs. mHFB =P < 0.05;
fasting insulin and fasting glucose were measured 2 wk before euthanasia;
fasting triglyceride, cholesterol, S-adenosylmethionine (SAM), and S-adenosylhomocysteine (SAH) were measured at the end of the experiment (n = 5 per group). ALT, alanine aminotransferase.
