Specialty products may offer particular health benefits or are targeted for specific conditions. These products may consist of whole foods or may be isolated compounds from natural or synthetic sources. Examples include antioxidants, probiotics (supplements containing friendly bacteria for the digestive tract), digestive enzymes, shark cartilage, or other animal products, or chemical extracts such as the hormone DHEA (dehydroepiandrosterone) and coenzyme Q10, an antioxidant.
In its natural state, sugar is a relatively harmless — even necessary — carbohydrate our bodies need to function. It’s found in fruits, vegetables and dairy as the compound fructose or lactose. The problem comes when sugar is added to foods during processing for added flavor, texture or color. Eating too many of these empty calories has many health effects, the most obvious being major weight gain. Added sugar drives your insulin levels up, messes with your metabolism and causes those calories to turn right into belly fat. Sugar goes by many names. Learn more about the surprising benefits of cutting back on sugar.
Eat all the foods you enjoy—but the key is to do it in smaller quantities, says Elisa Zied, RDN, who has lost and kept off more than 30 pounds since her highest weight in high school. In fact, she says it's the number one change she made that's helped her maintain her smaller frame. "I didn't want to feel deprived as I had in previous attempts to lose weight," she says. The worst thing you can do is be too strict, then rebound by overeating because you're not satisfied.
Total sales for the U.S. dietary supplement industry in 2006 are estimated at $22.1 billion, with vitamins accounting for $7.2 billion of that, says Patrick Rea, editor of the market research publication Nutrition Business Journal. Included in this total are not only sales of vitamins, but also those of minerals, herbs/botanicals, sports supplements, meal supplements, and weight loss products.
We've heard a lot of encouraging news about supplements. A series of studies hailed vitamin D as a possible defense against a long list of diseases, including cancer, diabetes, depression, and even the common cold. Omega-3 fatty acids have been touted for warding off strokes and other cardiovascular events. And antioxidants such as vitamins C and E and beta carotene were seen as promising silver bullets against heart disease, cancer, and even Alzheimer's disease.
Considering average dietary needs and the prevalence of certain health conditions, some basic guidelines may provide the foundation for the effective use of nutritional supplements. First, a high quality, broad-spectrum multivitamin and mineral supplement, taken once per day, is recommended to provide a range of nutrients. This should contain the B-complex vitamins B6, B12, and folic acid, which may help prevent heart disease, and the minerals zinc and copper, which aid immunity. In addition to a multivitamin, antioxidants can be added to a supplementation routine. These include vitamin A (or beta-carotene), vitamin C, and vitamin E, and the mineral selenium. Antioxidants may have several positive effects on the body, such as slowing the aging process, reducing the risks of cancer and heart disease, and reducing the risks of illness and infection by supporting the immune system. Coenzyme Q10 is another antioxidant in wide usage, as studies have shown it may improve the health of the heart and reduce the effects of heart disease. Essential fatty acids, particularly omega-3, are also recommended as they are involved in many important processes in the body, including brain function. Calcium supplementation is recommended for the elderly and for women, to strengthen bones and prevent bone loss. Calcium supplements that are balanced with magnesium have a less constipating effect and are better absorbed.
The U.S. Department of Health and Human Services declared last week National Women’s Health Week (May 14-20th), but in reality we should be taking care of ourselves and have this awareness all year round, right? To kick this month off inspired by women’s health, let’s talk about health, nutrition, and of course answer your questions from Instagram, Twitter, and email from over this year!
In 2015, the Australian Government's Department of Health published the results of a review of herbal supplements to determine if any were suitable for coverage by health insurance. Establishing guidelines to assess safety and efficacy of botanical supplement products, the European Medicines Agency provided criteria for evaluating and grading the quality of clinical research in preparing monographs about herbal supplements. In the United States, the National Center for Complementary and Integrative Health of the National Institutes of Health provides fact sheets evaluating the safety, potential effectiveness and side effects of many botanical products.
For example, while increased consumption of fruits and vegetables are related to decreases in mortality, cardiovascular diseases and cancers, supplementation with key factors found in fruits and vegetable, like antioxidants, vitamins, or minerals, do not help and some have been found to be harmful in some cases. In general as of 2016, robust clinical data is lacking, that shows that any kind of dietary supplementation does more good than harm for people who are healthy and eating a reasonable diet but there is clear data showing that dietary pattern and lifestyle choices are associated with health outcomes.
