By now, after almost 8 years of experience we know that biestmilch
interacts with the body clock. It can bring rhythm back for example if
you suffer from jetlag or from sleeplessness because of a burn-out,
moreover it influences cholesterol levels positively. I found the
following article some time ago and I think especially after the
holidays and at the beginning of a New Year with all its good
resolutions it makes sense to post it.
The article shows nicely how tightly metabolism and gene expressions are interlinked. Our food is contributing so much to our well-being. This fact is unfortunately extremely underestimated. You can spare yourself a lot of troubles by eating good. Biestmilch is an unbelievable powerful food stuff!
Dietary factors shown to influence sleep pattern

The body’s circadian rhythm — the internal ‘clock’ that regulates physiological processes — can be shifted by eating more fat, say researchers. This surprising finding suggests that a more complex interplay exists between the body clock and metabolism, with implications for disorders such as diabetes and obesity.
The circadian rhythm is a near-24-hour cycle that is known to be modulated by sunlight and eating schedules. Previous studies have shown that a disrupted circadian rhythm leads people to crave high-fat foods. And a study out recently shows that children who lack sleep risk being overweight.
This is an issue of increasing concern as researchers attempt to elucidate the link between disturbances in circadian rhythm and health conditions such as obesity, heart disease and diabetes.
Joseph Bass, an endocrinologist at Northwestern University in Evanston,
Illinois, fed a group of male mice a diet in which 45% of the calories
were derived from fat, and monitored their daily wheel-running
schedule. Mice given high-fat food had 23.8-hour daily cycles, whereas
the body clock in control mice, whose caloric intake included only 16%
fat, was 23.6 hours long. The internal time change occurred before the
mice had gained any weight, although the researchers did not measure
changes in body-fat percentage.
“This is the first time that a paper has really shown the impact of
feeding on the molecular and behavioral expression of the circadian
rhythm,” says Eve Van Cauter, a sleep researcher at the University of
Chicago in Illinois, who was not affiliated with the study. “In a
human, this would mean the person would have increased difficulties
going to bed at a reasonable time,” she says. “That might result in
insomnia or night-eating”, which further boost the risk of obesity and
diabetes.
The link between circadian rhythm and metabolism is not surprising,
says Bass, because the two systems share many molecular signalling
pathways. The expression patterns of some genes involved in lipid
metabolism change in 24-hour cycles, and several nuclear receptors that
are activated by sterols regulate expression of clock-related genes.
In addition, mice bearing mutations in the circadian-rhythm gene Clock
show signs of metabolic dysregulation, including obesity and altered
expression of genes involved in appetite regulation.
