HEALTH AND NUTRITION – Dr. Sopler's Facts and Stats on Ways to Keep You Healthy

Decline of memory is one of the major concerns as we get older. The reviewed research investigated factors affecting memory, and it is an important study because these are things we can do something about (Singh-Manoux A, et al. 2012).

The participants were 6,401 adults, aged 39-63 years in 1991-1993. Data on weight using body mass index (BMI) was collected and metabolic status was evaluated using triglycerides, high density lipoprotein (HDL). The participants were also evaluated for the use of lipid lowering drugs, if they had high blood pressure or if they were using blood pressure medications. Glucose was measured and it was recorded if the participants were using medications for diabetes. Four cognitive tests were administered in 1997-1999, 2002-2004, and 2007-2009. Abnormality of the metabolic status was defined as 2 or more of the above listed factors.

The results documented a faster cognitive decline in the participants with both obesity and metabolic abnormality.

The good news about this is that these are factors we can do something about by adapting a healthy lifestyle and eating habits. For a program that works, log on to thespecialeffectsdiet.com.

You may have heard that some research suggests that it may not be healthy to take vitamin E. Usually these kinds of studies rely on people filling out food questionnaires which may not always be that accurate. That is why the reviewed research is interesting, since the researchers measured plasma tocopherols, tocotrienols and markers of damaged vitamin E (Mangialasche F, et al. 2011).

Usually when vitamin E is studied only the most common form is considered. This study tested all forms of vitamin E and looked at the association between the vitamin E levels and mild cognitive impairment and also Alzheimer’s disease.

When participants with normal cognition were compared with participants having mild cognitive impairment and Alzheimer’s disease, those with cognitive impairment and Alzheimer’s disease had lower level of total tocopherols, total tocotrienols, and total vitamin E. Both of these conditions were also associated with increased vitamin E damage.

The conclusion of the research was that low plasma tocopherols and tocotrienols levels are associated with increased odds of mild cognitive impairment and Alzheimer’s disease.

What this shows us is that vitamin E is indeed important, but it is important to take a vitamin E complex, not only one type of vitamin E. You can read more about a good vitamin E complex by clicking here.
