Nutritional supplements are exactly that, supplements to a healthy, nutritious diet. One should not take nutritional supplements in the hope that they will make up for a poor diet and lack of exercise, they will not! There are some nutritional supplements including some vitamins and minerals, as well as other nutrients/cofactors that one can use in conjunction with a healthy diet to promote optimal health. For example, to consume the amount of vitamin E that has been shown to protect the body against free radical damage, one would have to consume a very significant amount of fat calories as vitamin E is found in foods that are high in fat such as vegetable oils, nuts and seeds. it makes sense to take a supplement of vitamin E rather than consuming lots of fat. The same goes for vitamin D. It's very difficult to get vitamin D in your diet as it isn't found in many foods and studies show that most people do not get enough vitamin D.
FDA regulations for nutritional supplements differ in important ways from those for prescription or over-the-counter drugs. For one thing, pharmaceutical companies have to gather data showing that a new drug is safe and effective in order to get the FDA's approval to market the drug. Makers of dietary supplements don't have to show that sort of proof. Be sure to let your doctor know about any nutritional supplement you plan on taking so you can discuss whether it's right for you and the appropriate dose.
If you count calories, count fat calories, too. Food labels indicate how many calories come from fat, both in actual grams and in percentages. This helps you assess the percentage of fat in your diet. If the total number of fat calories is 30 percent or more of the total calories you consume in a day, you probably need to cut back. But don't be misled by terms like "lower fat." Ask yourself "lower than what?" and look at the overall percentage of fat calories in the food.
The daily calcium recommendations are 1,000 milligrams a day for women under 50, and 1,500 milligrams a day for women 51 and older. Oddly enough, these are the same requirements for men, who are much less prone to osteoporosis than women. But the recommendation takes into account the fact that women are smaller than men. Thus the amount of daily calcium is greater for women on a proportional basis.
Men who choose to drink and can do so responsibly may benefit from one to two drinks a day, counting 5 ounces of wine, 12 ounces of beer, or 1.5 ounces of spirits as one drink. But women face an extra risk: Even low doses of alcohol can raise their risk of breast cancer. So women who choose to drink might be wise to limit themselves to half as much as men.
The total fat in your daily diet should average no more than 30 percent of your total calories consumed. And saturated fat should be no more than 10 percent of those 30 percent of calories. The amount of fat and saturated fat you eat depends on the foods you select and consume that have fat in them. Consider consulting with a nutrition professional to learn more about how to calculate your fat needs and to not exceed what are healthy amounts. There are many tools available to help you determine how much fat you should consume each day based on your current energy and nutrition needs. Reading food labels is one way to begin to identify where and how much fat is in particular food items.
