Do they really work?
First, one must be careful. One negative aspect of self-medication with herbal supplements is the fact that some products has been shown that the effects of prescription and over-the-counter counter. For example, in 2001, Dr. Piscitelli of the National Institutes of Health (NIH) showed a significant drug interaction between St. John’s wort (Hypericum perforatum), herbal products sold as dietary supplements, and indinavir, a protease inhibitor for HIV infection treatment. This herb also cause negative interactions with chemotherapy drugs and cancer drugs KB.
Experts usually recommend a balanced diet is healthy nutrients (omega-3, antioxidants, etc.) to get from the foods you eat, instead of taking supplements. Several studies to date have shown that supplements direct positive impact on the health brains. More importantly the best dosage of supplementation is unknown.
Summary of new findings on three popular dietary supplements.
1) DHEA (a steroid precursor of testosterone and estrogen is said that the aging): Conclusion of a two year study at the Mayo Clinic in Minnesota and the University of Padua in Italy showed that DHEA not breach the power to improve physical performance, or other measures of health. The principal author of the study, Dr. Nair (2006) said: “There is no beneficial effect on the quality of life observed. There is no evidence based on a study that DHEA has an anti-aging effects.”
2) Ginkgo biloba (an “over-the-counter to promote memory” to be completed): In 2002, Dr. Paul Solomon of Williams College, found that “when carried out following the manufacturer instructions, ginkgo no measurable benefits in memory or cognitive function offers on healthy adults with cognitive function, “Dr. Burns (2006), University of Adelaide. Australia found a better long-term memory in healthy fifty age 5-79 years, but no other cognitive measures improved for the younger participants. Elsabagh Dr. (2005) of King’s College London shows that ginkgo more attention in the beginning and memory. However, there is no benefit after 6 weeks, indicating that tolerance develops rapidly. A recent randomized trial (DeKosky et al., 2008), conducted in five academic medical centers in the United States and in 2587 volunteers from 75 years of age with normal cognition, showing that Ginkgo biloba at 120 mg twice a day is not effectively reduce the overall incidence of dementia.
3) Omega-3 fatty acids (components membrane of neurons): Dr. Fontani working at the University of Siena in Italy, a link to the omega-3 supplements with attention and physiological functions increased, especially that involving complex cortical processing .
As you can see, er is no reason not too many places in deze aanvulling verwachten, and focus on a balanced diet aan de important lifestyle factors supplement, such as physical and mental exercise.
Manual for the Brain-friendly power:
First, the brains consume a large amount of glucose. One of the earliest symptoms of dementia is a decline in the ability to efficiently use the brains of glucose. Thus the core dysfunction of diabetes, some neuroscientists refer Alzheimer’s a Type 3 diabetes.
The brain is an organ that is fat. Fat present in the membrane of neurons flexible. These fats are omega-3 and omega-6 fatty acid molecule. Our brains are very dependent on the intake of fat to eat enough fatty acids. Omega-3 fatty acids in cold water fish (such as mackerel, herring, salmon and tuna), walnuts and kiwi fruit. Docosahexaenoic acid or DHA, is the most omega-3 fatty acids in cell membranes in the brains.
In general, the brains are very sensitive to oxidative damage. This is why antioxidant foods have become popular for their positive effects on brain activity. Antioxidants are found in various foods: Alpha lipoic is found in spinach, broccoli and potatoes, vitamin E in vegetable oils, nuts, green leafy vegetables, vitamin C in citrus fruits and some plants and vegetables. Berries known for their antioxidant capability, but it is unclear which of the many components have an effect on cognition.
Based on these observations, such as Dr. Larry McCleary experts recommend one diet with oily fish, fruit and salad, non-starch fruits (like berries) – High in the fight against free radicals compounds – and nuts.
