Discover another way to bone up, find out how weekend splurges add up and see why it is important to check you heart before you start exercising.

Eat your O's to get E

Researchers at Oregon State University found that the bioavailability of vitamin E - an antioxidant that is believed to play a role in cardiovascular and neurological health - was 6 to 26 times greater when the vitamin was consumed in a fortified cereal rather than a pill. Other good sources of vitamin E are vegetable oils, peanuts, whole grains, wheat germ and spinach.

Another way to bone up

Fruit and vegetable consumption is known to reduce urinary calcium excretion in adults, and a University of Tennessee study of 56 girls aged 8-13 suggests that it may also affect bone growth. Girls who reported eating three or more servings of fruits and vegetables per day had greater bone area of the whole body and lost less calcium in their urine than did girls who ate fewer fruits and vegetables.

Weekend splurges add up

According to the Continuing Survey of Food Intakes by Individuals published in Obesity Research, Americans between the ages of 19 and 50 eat an average of 480 more kilojoules on each weekend day than they do on weekdays - enough to equal a 2.5kg weight-gain over the course of a year. You could even things out by drinking one less beer at happy hour, but we'd rather ride longer - a 70kg cyclist riding at 19km/h burns 568 kilojoules in just 15 minutes.

Be heart smart

Because sudden death is often the first sign of an underlying heart problem, active people and athletes should be more aware of heart health and the dangers posed by undiagnosed heart ailments, according to cardiologist and physician John D Cantwell. He warns against starting an exercise programme or increasing its intensity without first being properly screened for heart problems. He suggests a standard questionnaire, cardiac exam and electrocardiogram for all athletes, as well as CT scans for older athletes and echocardiograms as needed.
