Diet: Diet And Brain Shrinkage

Elderly people with higher levels of vitamins B, C, D, E and omega 3 fatty acids in their blood had better performance on mental acuity tests and less of the brain shrinkage typical of Alzheimer's disease. Consistently worse cognitive performance was associated with a higher intake of the type of trans-fats found in baked and fried foods, margarine, fast food and other less-healthy dietary choices.

Health Alert: The Uninsured!

Lack of health insurance is associated with less preventive care, delays in diagnosis and unnecessary deaths. However, insurance status doesn't affect the quantity (or value) of imaging services received by patients in a hospital, in-patient setting. Uninsured hospital in-patients who underwent imaging received the same number of imaging services as insured persons. The uninsured received fewer interventional and image-guided procedures but more computed tomography (CT) studies.

Mental Attitude: Not So Smart At 45?

A human's ability to remember data, to reason, and to understand things properly can begin to worsen at 45 years old (not at 60 years old, as previously believed). Mental reasoning among males aged 45-49 dropped by 3.6%, and 9.6% in the 65-70 age group. Among females, the decline was 3.6% for those aged 45-49, and 7.4% among those aged 65-70. This demonstrates the importance of promoting healthy lifestyles, particularly cardiovascular health, as there is emerging evidence that "what is good for our hearts is also good for our heads." Risk factors linked to cognitive decline: hypertension, obesity and high cholesterol levels.

Exercise: Colds And Exercise

Different levels of exercise can significantly increase or decrease your chances of catching a cold. If you tend to be a couch potato, then you will catch 2-3 colds per year, on average. Regular moderate exercise can reduce the risk of catching cold-like infections by 33% (this effect has been shown to be the result of the cumulative effect of exercise leading to long-term improvement in immunity). Prolonged strenuous exercise, such as marathons, can make an individual more susceptible to catching colds. We are constantly exposed to viruses, but it is our immune system that determines whether we get sick or not.
