Ya. Luego en la hoja de calculo he visto la referencia que citas, lo que me
escama es que toda la evidencia sea ese único articulo y que sea en Japón...
pais del mundo que más pescado consume.

Saludos

Y digo yo, ¿esta gente habrá tenido en cuenta que en Japón todo el
mundo toma té verde, ya que allá es el sustituto del agua en nuestra
cultura?

"PURPOSE: To examine the relation between green tea consumption and
serum lipids and lipoproteins.

METHODS: The subjects were 13,916 workers (8476 men and 5440 women)
aged 40-69 years at over 1000 workplaces in Nagano prefecture, central
Japan. They underwent health screening offered by a single medical
institute between April 1995 and March 1996 and did not have morbid
conditions affecting serum cholesterol levels. Serum concentrations of
total cholesterol, high-density lipoprotein (HDL) cholesterol and
triglycerides were measured at the screening. The consumption of green
tea and other life-style characteristics were ascertained by a
questionnaire. The data were analyzed with multivariate linear model.

RESULTS: Daily consumption of green tea was reported by 86.7% of
subjects. Green tea consumption was, statistically, significantly
associated with lower levels of serum total cholesterol in both men
and women while its associations with serum triglycerides and HDL
cholesterol were not statistically significant. The inverse
association of serum total cholesterol with green tea consumption
appeared to level off at the consumption of more than 10 cups/day.
Excluding the outlying subjects drinking more than 10 cups/day (0.4%),
the regression analysis adjusting for age, body mass index, ethanol
intake, smoking habit, coffee intake, and type of work showed that
daily consumption of one cup of green tea was associated with a
reduction in serum total cholesterol by 0.015 mmol/L (95% confidence
interval 0.006 to 0.024, p < 0.001) in men and 0.015 mmol/L (0.004 to
0.025, p < 0.01) in women. After additional adjustment for selected
dietary factors, the inverse association remained statistically
significant; one cup of green tea per day was associated with a
reduction in serum total cholesterol by 0.010 mmol/L (0.001 to 0.019,
p = 0.03) in men and 0.012 mmol/L (0.001 to 0.022, p = 0.03) in women.

CONCLUSION: Consumption of green tea was associated with lower serum
concentration of total cholesterol in Japanese healthy workers age
40-69 years; however, green tea consumption was unrelated to serum
HDL-cholesterol and triglycerides."
