Q: Which provides more vitamin C, refrigerated ready-to-drink or frozen concentrate orange juice?
A: Freshly-squeezed orange juice is generally tops for vitamin C content, providing at least a day’s worth in just one six-ounce glass. However, more convenient options such as frozen concentrate or bottled juice (100% juice made from concentrate or not) are all excellent sources of vitamin C. The vitamin C content varies some among brands compared to official USDA information, but you can usually count on the six ounces (the recommended serving) supplying 50 to 75 milligrams of the vitamin. That’s half to three-quarters of currently recommended daily amounts. Of course, vitamin C is just one of many vitamins, minerals and protective plant compounds we get from vegetables and fruits, so be sure to focus on getting a wide variety and plenty of produce. Whichever form of juice you choose may be based on price, convenience or flavor.
Q: Is it safe to lose weight while breastfeeding?
A: Certainly, in fact the extra calories you use in producing breast milk may even help. Exclusive breastfeeding, meaning giving your baby nothing else, is recommended as the optimal choice for baby’s and mother’s health for the first six months. In addition, it is associated with greatest weight loss. To maintain successful milk production, the key is to make sure you are losing weight gradually and with healthy food choices. Limit consumption of high-sugar drinks and watch out for high-fat or high-sugar snack foods and desserts without totally depriving yourself. Portion control can be important as well; if you’ve gotten used to larger portions during pregnancy, taking three-quarters of your usual portions of meat and starchy foods (pasta, cereal, potatoes) can make a significant difference. Remember, too, that adding in physical activity, such as taking your baby for a walk every day, also helps to create the difference between calories consumed and calories burned that leads to weight loss.
The American Institute for Cancer Research (AICR) is the cancer charity that fosters research on the relationship of nutrition, physical activity and weight management to cancer risk, interprets the scientific literature and educates the public about the results. It has contributed more than $100 million for innovative research conducted at universities, hospitals and research centers across the country. AICR has published two landmark reports that interpret the accumulated research in the field, and is committed to a process of continuous review. AICR also provides a wide range of educational programs to help millions of Americans learn to make dietary changes for lower cancer risk. Its award-winning New American Plate program is presented in brochures, seminars and on its website, www.aicr.org. AICR is a member of the World Cancer Research Fund International.All active news articles
