Does excercise has anything to do with digestion?

Re peristalsis, is it possible to lose that function to the extent that it is impaired in the lowest portion of the bowel so that extra means must be used - manual or pharmaceutical - for elimination to occur?

If so, can habitual use of such means further destroy natural peristalsis? And if so, can this be reversed or corrected?

Thank you.

In re to peristalsis, is it possible for loss of this process to occur only in the lowest part of the colon, such that extra means must be taken to eliminate stool? ... manual and/or medical.?
If so, does long-time use of extraneous means further damage peristalsis?

If so, is there any way to reverse this situation?

Thank you.

what is the exact cause of hic-cups with digestion. For several months I would get episodes which would last for sometimes two days. I tried everything including the website 50 ways to get rid of hic-cups the only thing that would finally work was Thorazine....which is what they give schizophrenics

Is it true that stress can produce acid in your stomach, and that this can be related to migraines? I'm asking because that's the theory in Ayurvedic medicine.

Fatty foods and alcohol go well together, not because the drink "loosens you up" as your guest suggested but rather has to do with the acidity of the alcohol (say wine) cutting through the fattiness of the meal.

Proponents of "high colonics" claim that fecal matter stays lodged in the colon for a long period of time. Is that true?

You've talked about flatulence, but I'm wondering if there's anything different about the gas in a burp? Do the same things that help w/flatulence also reduce belching?

And has anything new been learned about the appendix & whether it has some function after all?

I drink water often (4-5 16oz. bottles of poland spring) a day. I suffered from constipation all my life. Recently I went to a nutritionist and she suggested taking magnesium pills. It is the best suggestion I had ever been told. Works great! and I don't get migraines any more either. My question, is there any harm taking magnesium daily?
Tahnk you

I've had bleeding problems with bowel movements and seepage so that I have to use liners. Gastroenterologist does a colonoscopy and says I'm OK but never addresses my problem. Metamusel made it worse. I take fish oil Omega 3 every day and eat a combination of flax, sesame, pumpkin and sunflower seeds with yogurt every day. Any advice?

What is the role of BURPING in digestion? My girlfriend says U burp a lot, but I don't even realize I do often times. Does this suggest a problem with my diet or need for more exercise, or is it just a quirk of my body vs others...

WHAT DOES IT MEAN WHEN YOUR INSIDES GURGGLE?
IF IT HAPPENS OFTEN IS THIS A SIGN OF A BACK UP OR SOMETHING SERIOUS? SHOULD I GET A COLON CLEANSE?

I have read in some "health nut"-type books (smile!) that mixing certain food categories when eating leads to poor health because some of these mixtures--starches and fruit; fruit and meats; sugars and heavy proteins; some folks say even starches and meats--lead to slower digestion and some of the food...uh...putrefying in the gut.

I have noticed that eating dessert too soon after a meal with a lot of meat leads to my feeling overly full for a while afterwards--but is there actually anything unhealthy about mixing such foods in meals (which is quite common to most cultures)?

I suffered chronically from flatulence until I finally had my appendix removed (acute appendicitis) I had suffered from many spells of colic until the surgery.

Why aren't your nutrition specialists mentioning lactose intolerance? After the age of 50, most people develop some degree of lactose intolerance, because of the decreasing inability to digest milk products; and the most common symptom of this flatulence. (I only recently learned about this from a gastro-enterologist.)

My father always tells me not to drink water when I'm eating. Is there anything to this advice?

I would be very interested in your guest’s thoughts on colon cleansing products.

Your guest's comment about turkey's not having much fat and therefore being healthy is the kind of thing that contributes to the confusion around what is and isn't healthy about fat.

A little known fact is that polyunsaturated fats, salad oils, may contribute to breast and prostate cancer.

Saturated fat is not a demon.

Omega 3 fats are usually deficient in the diet.

Please comment about people without gallbladders and how they can have fat malsbsorption.

Thanks

I've been told that raw foods are easier to digest than cooked foods, but that seems counter-intuitive to me. Something about self-digesting enzymes? But I know from personal experience that when I tried to go raw I lasted all of one day because my body freaked out. Which is it though? Easier or harder?

I've heard that it takes 24 hours for food to digest, so why then, when I eat something bad, does it work its way out in under an hour?

Dec. 11 2009 01:30 PM
Pamela from Brooklyn

I remember when I was pregnant, I heard that digestion was slowing down so that my body could get all the nutrients for the growing baby. Why isn't digestion that efficient ALL the time? Do our bodies just routinely pass up available nutrients?

• Is it true that fruit takes about 30 minutes, vegetables about 45 minutes, meats much longer..to digest?
• Is it true that it is better NOT to eat different food categories together...for improved digestion?
• Is it true that eating fruit first thing in the morning and alone will "wake up the liver"?

Barbara Sulcov from Westchester

Why do I get heart palpitations that last for hours after drinking wine and vodka but not beer? The heart palpitations last for at least 10 hours. I am in my early 50s, is this related to menopause?

How has cooking our food played a part in human evolution? Our ancestors ate raw food diets- are our modern digestion systems much different from our ancestors because we started cooking at some point?

Everyone knows that bacteria plays an important role in digestion. Any bacteria? Which one or which mix is "healthy"?

How important is to be "regular"? What effect has constipation on weight gain/loss, if any?

Is the old wives' tale about swallowing gum true?

Why were we told to wait before swimming?
