sburgernutr, if you're still reading, I'm guessing the guests' answers are based on, & intended for, a society where few people can't get adequate nutrition, not Third World populations like the people in your Bangladesh project. The results you describe probably don't translate to people whose night vision is within normal limits & who don't have a vitamin A deficiency they need to correct.

I will happily provide peer-reviewed evidence to Mr. Anahad O'Connor about carrots and other beta-carotene rich food and their impact on night blindness. In fact, I will lend him my signed copy of Nutritional Blindness written by Dr. Sommer on the topic. Our Bangladesh project actually did a wonderful study with tens of thousands of subjects that showed a direct relationship between the number of varieties of beta-carotene rich vegetables grown by women in home gardens, consumption of those vegetables and decreases in night blindness.

Does eating right before going to sleep result in fat going to the stomach and/or waist?

So vitamin A (in carrots & other orange/yellow vegetables) doesn't help w/night vision? Even in people who don't have good night vision? I have the impression that a lot of these ideas are based on thinking that if a problem comes from a vitamin or mineral deficiency, getting more of the vitamin or mineral helps even if you don't have that problem. (Actually, the same principle is at work for drugs--look at the demand for Viagra in men who don't have ED & for anti-obesity drugs in people who want to lose 10 lbs.)

SOo what do you think about UMCKA and something like AIRBORNE?

I really have to respectfully disagree. There is a HUGE body of evidence on decreasing the rates of night blindness by eating vitamin A and beta-carotene rich foods. Carrots are one of them. This is still currently an issue in many countries around the globe. I worked for Helen Keller International for 7 years and studied under Dr. Alfred Sommer. He later became Dean of Johns Hopkins School of Hygiene and Public Health and won the Lasker Prize for his work on vitamin A deficiency. Really, I am SHOCKED that this statement was on the air.

The thing about sitting too close to TV being able to hurt your eyesight - I believe that older TV sets emitted a considerable amount of UV radiation, which would have the potential to damage the retina. I don't think that is a problem in newer TVs and other screens.

What about going from an oven to walk-in refrigerator?

Is it true that nightshade vegtables increase inflammation?
I have read it is not true, but others swear it does, especially if you have arthritis or a auto-immune condition.

I used to catch a cold at least twice a year. Since I started going to gym, doing some martial arts and jogging like crazy i haven't been sick for last six years. There was nothing else changed in my life style. Can physical activity have such a strong effect on immune system?

Can you ask about BPA leaching and cellphone radiation?

What about the effect of computer screens on eye sight?

I often get colds and a flu in the winter months. Have there been studies about taking supplements such as Vitamin C, Echinacea, or Zinc?
Also, what do you think about UMCKA and AIRBORNE?

Any kind of fluid can provide hydration, but what about the idea (fairly new, I think) that the body doesn't register calories in liquids, so when people drink high-calorie beverages like sodas, they don't compensate by cutting down on calories from food?

The aforementioned Cold Center, in Cardiff, was said to be in England. Cardiff is the capital of Wales.

My sister's home in a large Florida city had lightening strike and enter the home through the chimney.

My doctor told me that fever flucuates because of cortisol levels. They diminish as the day progresses so therefore inflammation increases.

Even if there is no physiological effect, could the psychosomatic impact of believing they work be significant?

Could cold stress the body, just as mental stress can, to lower the effectiveness of the immune system and thus make catching a cold more likely?

So, germs and the body's defenses don't behave differently in cold? I don't buy it.

I've also read that kids in day care, even though (or because?) they get sick at earlier ages, develop better immunity than kids the same age who don't go to day care. Does this mean they get sick less once they're in school?

What about antioxidants like the ones supposedly in green tea? Do they help to undo the effects of stress on health?

What about drafts?

Can they cause colds or muscle strain or whatever else people think.

My wifes mother is from teh balkans and she will not ever let us have two windows open in the summer to let a breeze form because of fear of the draft...

8 glasses of water mandatory a day is a myth!

Does mega dosing on Vitamin C really help a cold?
does anything actually help shorten the life span of a cold?
