As a personal trainer, you may recognize this scenario:
“Mary” is a fictional 30-year-old woman who was diagnosed with multiple sclerosis soon after her 21st birthday. She is often tired in the morning, even when she gets a full night’s worth of restful sleep, which is rare. The fatigue is unpredictable, gets worse throughout the day and tends to be triggered easily. Muscle spasms and weakness in her legs make it difficult for her to walk long distances.
We already understand the many benefits of the Mediterranean diet, but a new study casts yet another convincing health vote in its favor.
A landmark global study shows that people who eat a plant-based Mediterranean diet supplemented with nuts or virgin olive oil may enjoy long-term benefits, including a 30% lower risk of cardiovascular disease.
Hoping to improve their health, many people opt for vigorous styles of exercise. New research, however, suggests that minimal-intensity, longer-duration physical activity may be best for insulin action and plasma lipids.
The study, published in PLoS ONE (2013; 8 ; doi: 10.1371/journal.pone.0055542), included 18 apparently healthy subjects around 21 years of age. Each participant was randomly selected to follow one of three protocols.
People with heart disease are at higher risk for cognitive impairment, providing more evidence of the interconnection between our physical and mental health. Mayo Clinic researchers found that in a study of more than 2,719 people aged 70–89, those with heart disease—especially women—were more likely to experience mild cognitive impairment, exemplified by problems with language, thinking and judgment.
Study findings appeared in JAMA Neurology
(2013; doi: 10.1001/jamaneurol.2013.607).
Maintaining a consistent twice-weekly yoga practice helped people with cardiac arrhythmia improve symptoms and reduce anxiety, noted a study published in the Journal of the American College of Cardiology (2013; doi: 10.1016/j.jacc.2012.11.060).
1. Since high blood glucose is dangerous, is low blood glucose healthy?
When blood glucose levels fall below 70 mg/dl, the condition is called hypoglycemia or low blood glucose. Since the primary fuel of the central nervous system (CNS) is glucose, low blood glucose can dramatically impair CNS function. Hypoglycemia can lead to dizziness, confusion, slurred speech, blurred vision and sleepiness (Gulve 2008).
