Medical advice is to reduce sugar consumption. Does this apply to 100 percent fruit juices, fresh fruit, sweetened cereal products or other fruit-sweetened products?
Dr. Roach says: I think it makes sense to limit sugar intake, as most North Americans take in remarkably large quantities of sugar. Recently, while giving a lecture at the medical school, I noticed that the carbonated sodas served contained 45 grams of added sugar per can. That’s more than the American Heart Association recommends in a day (no more than 25 grams of added sugar per day for women, 40 grams a day for men)! Be careful of products that claim to be sweetened by fruit juice or fruit sugar; this still counts as added sugar.
I do make an exception for fruits, as the body processes natural sugars from fruit differently. You can try this out at home by eating four medium-size oranges or drinking its equivalent in an 8-ounce (250 ml) glass of orange juice. I think you will find a big difference in how full you feel.
Although reducing sugar is critical for diabetics and is very important for anyone trying to lose weight, even for people with no sugar or weight problems, the evidence is accumulating that eating too much added sugar increases future risk for heart disease and diabetes.
My wife has wet AMD. Her ophthalmologist gave her some vitamins (to take three times a day). They include 25 mg of zinc oxide. She has read somewhere that women should not take more than 8 mg of zinc a day. These vitamins would total 75 mg daily. Are zinc and zinc oxide the same? Can she take these vitamins?
Dr. Roach says: The usual dose of zinc for age-related macular degeneration is 80 mg daily of zinc oxide. Twenty-three percent of zinc oxide is elemental zinc, so this is about 18 mg of elemental zinc. The ophthalmologist is giving a very standard and safe dose for AMD.
The U.S. recommended daily allowance for zinc is 11 mg for men, 8 mg for women. Very high doses of zinc can be dangerous, but this dose is still in the safe zone.
