…….A small quantity will satisfy and keeps hunger away. טובא גריר, פורתא סעיד
A few FASCINATING medical-Pesach issues.
טובא גריר, פורתא סעיד-ברכות לה ,תעמוד ב
A large quantity has an appetizing effect; a small amount sustains. [Berachot 35b]
It seems strange, but a large quantity of wine will stimulate one’s appetite, whereas a small amount will satisfy and keep hunger away.
Therefore, if one drinks wine on Erev Pesach he should drink a larger [not to small] amount] so that he will not suppress his appetite for the seder.
The journal Science  published that a rapid infusion of glucose in the duodenum increased rabbits’ appetite, and a slow infusion decreased the appetite.
This may explain the statement of the Talmud.
[Source; insights, a Talmudic treasury by rabbi Saul Weiss]
So, for over-eaters: it is clear what to do.
Drink a tiny bit of wine before the meal [one or two teaspoons]
[Rambam Mishna Tora [ chapter 5, halacha 2 ]:
[translation by Rabbi Eliyahu Touger, Moznaim publ.corp]
“Regarding these five species of grain: if [flour from these species] is kneaded with fruit juice alone without any water, it will never become leavened.
Even if [flour] is placed in [these] juices the entire day until the dough rises, it is permitted to be eaten [on Pesach], for fruit juice does not cause [dough] to become leavened.
It merely causes [the flour] to decay.
The following are [included in the category] of fruit juice: wine, milk, honey, olive oil, apple juice, pomegranate juice and all other similar wines, oils, and beverages.
This applies so long as no water whatsoever is mixed with them.
If any water is mixed with them, they cause [the flour] to become leavened.”
The smallest amount of added water will cause the mentioned grains to become leavened [to become chametz]
It is fascinating to remark here on the halacha brought by the Rambam and to relate this to the fact that in traditional medicine [as well in homoeopathy], all water is not just water.
Water in fruits is different
from plain water [ both of them are H2O in chemistry]
In homoeopathy, water shaken very vigorously differs [from the water before it has been shaken] when examined with atom spectrografie.
It is as if water has a “memory” [like footprints in the snow, which show-like a memory- that somebody passed there some while ago]
On seder Pesach, all of us will remember leaning on the left side.
[Kitzur shulchan aruch [chapter 71,halacha 5 ]
“It is beneficial to begin one’s sleep while lying on the left side and then change to the right side.
These benefits one’s health since the liver is on one’s right side, and the stomach is on one’s left. When one leans to the left, the liver will lie on the stomach and warm it with its heat. It will hasten the digestion of the food. After the food has been digested, it is preferable to lean to the right, thus allowing the stomach to rest and the waste to descend. One should not frequently turn from side to side.”
It is remarkable that I found in only one medical textbook from 1959 [and in no other book] that the temperature in the liver veins is above 41 degrees!!
Then it becomes understandable that lying on the left side “cooks” the food in the stomach [see above], which increases digestion significantly!!
Do you know that recently it has been found that people who sleep only on one side have more tendency for kidney stones?
