Science has established a considerable link between nutrition (diet) and health. For example, very-low-fat diets have been shown to reverse atherosclerosis, and weight loss can improve type 2 diabetes in some people. Although body cells will age no matter what health practices are followed, the risk of poor health can be decreased through diet and lifestyle. A consistently healthful diet and a regimen of regular physical activity have proven effective in maintaining a healthful body: Muscles are firmer, bone fractures are less likely, and the person looks and feels better. The secret to enjoying “youth” throughout life is to establish a healthful physical, mental, and social framework.
The 1994 DSHEA law allows companies to market herbal products without prior approval by FDA as long as they make vague structure/function claims. Jamila has to rely on the truthfulness of the manufacturer of the herbal product concerning any possible health benefits from use. Ideally, Jamila should make sure that any use of herbal products follows four specific guidelines:
Follow label directions carefully and start with a low dose.
Increase the dose gradually as needed, watching for potential side effects. These potential side effects should be listed on the label.
Do not use products that contain mixtures of herbal substances. Many of these products have been especially linked to health problems with use.
