Many women and teenage girls don't get enough calcium. Calcium-rich foods are critical to healthy bones and can help you avoid osteoporosis, a bone-weakening disease. Additionally, recent studies suggest that consuming calcium-rich foods as part of a healthy diet may aid weight loss in obese women while minimizing bone turnover. The National Institute of Medicine recommends the following calcium intake, for different ages:
Manufacturers must follow certain good manufacturing practices to ensure the identity, purity, strength, and composition of their products. If the FDA finds a product to be unsafe or otherwise unfit for human consumption, it may take enforcement action to remove the product from the marketplace or work with the manufacturer to voluntarily recall the product.
We live in a modern world with amazing advancements in technology, yet our soil lacks minerals that it once contained causing whatever grows out of it (i.e. fruits, vegetables, and whole foods) to be significantly lower in minerals than it once was. Not only is our soil different, but our food takes a long time to get to us! Unless we’re growing our own whole food in our gardens, picking it out with our bare hands, and washing it off before eating, most likely our produce has been picked weeks before it reaches your grocery store and is purchased by you. This entire process can take weeks and cause nutrients to be depleted from the whole food (2).
Now, the benefits of good nutrition are fairly obvious to most of us. You have more energy, your health improves, and your productivity blossoms. Healthy eating also plays a huge role in maintaining a healthy weight, which means a decreased risk of type 2 diabetes, certain cancers, heart problems, high blood pressure, and a host of other health ailments. (Genetics also plays a significant role. I'm not some crazy person who thinks genes don't matter.)
On a related note, if you’re thinking “I’ll just put less food on my plate” … it’s not that simple. The picture below explains why. When you eat a small portion off of a large plate, your mind feels unsatisfied. Meanwhile, the same portion will feel more filling when eaten off of a small plate. The circles in the image below are the same size, but your brain (and stomach) doesn’t view them that way.
The recommended nutrient reference intake (NRI) has been defined by UK authorities and the EU Food Safety Agency as the dose that is adequate for 95 percent of the population. [32] These authorities have given recommendations for a total of 41 chemical substances, [33] including 13 vitamins, 17 minerals/trace elements, 9 amino acids and two fatty acids. The problem with such guidelines is that when using the same 0.95 fraction for just 16 of the essential nutrients, the fraction of the overall population that has their needs met with the RDA is less than half (0.9516 = 0.44). Given the above assumption, the proportion of the population having all nutrient needs met falls below 25 percent for 30 nutrients (0.9530 = 0.21). These 25 percent will not necessarily get optimal amounts, just enough so that they probably will have no deficiencies in accordance with established standards. Each individual is different and has different biochemical needs, so we all need different doses of essential nutrients. Many vitamins and minerals can give additional benefit when taken at higher doses.
In the United States, the National Health and Nutrition Examination Survey (NHANES) has investigated habits of using dietary supplements in context of total nutrient intakes from the diet in adults and children.[101] Over the period of 1999 to 2012, use of multivitamins decreased, and there was wide variability in the use of individual supplements among subgroups by age, sex, race/ethnicity, and educational status.[115] Particular attention has been given to use of folate supplements by young women to reduce the risk of fetal neural tube defects.[116][117]
If you suspect that you have had a serious reaction from a dietary supplement, let your health care provider know. He or she may report your experience to the FDA. You may also submit a report to the FDA by calling 800-FDA-1088 or completing a form online. In addition, report your reaction to the dietary supplement company by using the contact information on the product label.
