Do you know what you are drinking?
A recent study found that orange juice markedly decreased the hardness and increased roughness of tooth enamel. “The acid is so strong that the tooth is literally washed away. The orange juice decreased enamel hardness by 84%”, said one researcher.
Weakened and eroded enamel may speed up tooth wear and increase the risk for decay to quickly develop and spread. Most soft drinks and fruit juices are acid and can potentially cause significant erosion of teeth. You can lessen the erosive effects by drinking or rinsing with water after consuming soft drinks or juices to lower the acid concentration in the mouth. Maintain good oral hygiene and see the dentist regularly.

Whiten your teeth to have that dazzling smile. There is no harm to your teeth. But becarful what you a drinking!!! Recent study at the Eastman Institute for Oral Health conclude that orange juice is very harmful to tooth enamel while whitening is perfectly safe.

The study suggested that there is no absolute way to prevent this but the longer the acid is in contact with the teeth the more the erosive effects. Drink or rinse with water after consuming soft drinks or juices to lower the acid concentration in the mouth. Maintain good oral hygiene and see the dentist regularly.

The study found the group that was almost completely sedentary had a much higher risk of death than the other groups when compared to even the group that did just a little bit of exercise. The article quotes one of the researchers as saying “you don’t have to be a triathlete in the way high end of the scale. Just get out of that least-fit group.”
The difference in physical activity between the least-fit group and the second-least-fit group was small – not much more than and extra half-hour of walking per week. It turns out that 30 minutes of exercise each week could add years to your life. Those in the least-fit group were twice as likely to die of heart disease than the second-least-fit-group. The article again, quote one researcher as saying “It’s not like there were a lot more diabetics or a lot more smokers, or anything like that, that may explain higher mortality in the least-fit group – we notice the one difference that stood out for us was the second-least-fit group was more physically active than the least-fit group.”
Participants in the most-fit group were 4 times less likely to die from heart disease than the least fit group. This group exercised roughly twice as much as the least-fit group or 1 hour per week.
To put this in perspective; if you walk for 10 minutes 3 times per week you can cut your risk of dying from heart disease be 50%!!!!

Even as little as 30 minutes of walking each week can extend your life
An August 2009 column in the Globe and Mail has reported on a study from Stanford University in California which concluded that, just a small amount of physical activity – a half hour stroll a week – can reduce the risk of mortality from heart disease by half.
The study suggested that rather than diet or general health status, physical fitness is the strongest predictor of mortality. The 20 year study test almost 4500 participants in their 50s and 60s who had no major health problems and ask them to use a treadmill. Participants asked how much exercise they did and were then placed in five groups from least fit to most fit and then followed for an average of 9 years to see how many of each group died during the course of the study. Deaths that were caused by factors unrelated to physical activity such as cancer or lung disease were excluded.
