Diet and Brian Shrinkage;

Elderly people with higher levels of vitamin 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 trans-fats found in baked and fried foods, margarine, fast food and other less healthy dietary choices.

The Uninsured!

Lake of health insurance is associated with less preventive care, delay in diagnosis and unnecessary deaths.However, insurance status does not effect the quantity (or value) of imaging- services received by patients in a hospital, in- patient setting. Uninsured hospital in-patient who underwent imaging received the same number of imaging services as insured person. the uninsured received fewer intervention and image-guided procedures but more computed tomography (CT) studies.

Not So Smart At 45?

A human ability to remember data, to reason, and to understand things properly can begin to worsen at 45-69 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 3.65% for those ages 45-49 and 7.4% among those aged 65-70. This demonstrate the importance of promoting healthy lifestyle, 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.

Regular moderate exercise can reduce the risk of catching cold like infections by 33% ( this effect has been to be the result of cumulative effect of exercise leading to long term improvement in immunity). Prolong strenuous exercise , such as marathons, can make an individual more susceptible to catching cold. we are constantly exposed to viruses, but it is our immune system that determines whether we get sick or not.
