Abstract

Effects of a polyunsaturated fatty acid (PUFA)-rich diet were investigated in 17 polycystic ovary syndrome (PCOS) patients. After a 3-month habitual diet period, dietary fats were partly replaced with PUFAs for another 3 months. The PUFA-rich diet increased plasma linoleic acid from 28.36 +/- 1.00% to 33.76 +/- 1.08% (P < 0.002) and alpha-linolenic acid from 0.52 +/- 0.03% to 1.06 +/- 0.10% (P < 0.0001). Fasting glucose increased from 76 +/- 3 to 95 +/- 3 mg/dl (4.2 +/- 0.2 to 5.30.2 mmol/liter; P < 0.0001), and the area under the curve for glucose during oral glucose tolerance test increased from 421 +/- 34 to 503 +/- 31 mg/dl (23.4 +/- 1.9 to 27.9 +/- 1.7 mmol/liter; P < 0.001). Plasma insulin did not change either at fasting or during oral glucose tolerance test. Fasting plasma free fatty acids decreased from 0.596 +/- 0.048 to 0.445 +/- 0.058 mg/dl (P = 0.037), and ketone bodies decreased from 9.14 +/- 1.57 to 3.63 +/- 0.62 mg/dl (895 +/- 154 to 356 +/- 61 micromol/liter; P < 0.003). Plasma 15-deoxyprostaglandin J(2) tended to decrease (from 239 +/- 65 to 171 +/- 60 ng/ml; P = 0.053). Plasma testosterone, free testosterone, SHBG, dehydroepiandrosterone sulfate, LH, FSH, and urinary estrogen conjugates did not change. Urinary pregnanediol 3-glucuronide increased from 18.6 +/- 2.2 to 31.0 +/- 5.7 micro g/mg creatinine (P = 0.038). In conclusion, increased dietary PUFA intake can exert significant metabolic and endocrine effects in women with PCOS.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
