Brushing and Flossing Diseases Away

How often do you brush your teeth thoroughly and floss? Do you pay enough attention to oral hygiene? If you don’t, you might want to consider taking oral hygiene more seriously because research has found that bad oral hygiene could potentially lead to detrimental diseases.

We know that the oral cavity is one of the places of your body that harbors the most bacteria. These bacteria often do not cause any significant harm to our body, given that we brush our teeth and floss regularly to get rid of these bacteria in our mouth. But when we do not clean our teeth regularly and thoroughly, these bacteria easily build up around our teeth and often cause inflammation of the gums. And in cases when the individuals who suffer from periodontal disease are not taking actions to improve their practice of oral hygiene, infections exacerbate and results in chronic conditions.

Usually, when we think of heart disease, we tend to associate it with obesity, hypertension, smoking, congenital conditions, and other genetic-related problems. But now we might want to add oral problems to our list of factors that contribute to cardiovascular disease. According to numerous studies, chronic bacterial infections in the gums from poor oral hygiene and serious periodontal disease increase an individual’s chance of developing heart attack and stroke.

If you have poor oral hygiene practice, it is likely that you will often accidentally scrape or damage the epithelial oral tissue in the mouth, especially the gums. When the oral tissue is damaged, pathogens can easily enter into the tissues and eventually penetrate into the bloodstream, which then carries these pathogens to other parts of the body, affecting other tissues and body systems and causing multiple inflammations in the body. For instance, a 2005 study conducted by the University of Florida even found oral bacteria inside artery plaque.

Other than heart attack and stroke, the myriads of oral bacteria may also play a role in knee arthritis. In a 2012 study which sought to examine the link between oral bacteria and knee osteoarthritis, the researchers found that out of the 36 patients with knee arthritis, five of them had gum microbes in the synovial fluid in their joints. Although the association between oral bacteria and knee arthritis is still not fully understood, these bacterial certainly worsens arthritis.

Therefore, it is important to brush your teeth regularly and thoroughly since oral hygiene is related to the health of the rest of your body. However, this is not to say that bad oral health has a direct impact on heart disease, since there are other confounding factors such as smoking and type of lifestyle.

Does the source of omega-3 matter?

 

It is clear that we need a certain amount of nutrients in order for our bodies to function normally. But the questions is, is the source of these nutrients better from supplementation or from whole foods?

Previous studies suggest that eating whole fish may have additional benefits to being a dietary source of omega-3. Omega-3 fatty acid is important in the prevention of chronic conditions such as cardiovascular disease and arthritis.

Rich sources of omega-3 include canola oil, walnuts, and fish oil. The Canadian Heart and Stroke Foundation recommends consumption of fat rich fish at least three times a week.

In 2012, Brazionis et al.  showed that eating fish had a greater and more positive impact on health than people taking fish oil supplements. The decrease in  the patient’s waist to hip ratio and blood pressure was more evident in people who ate fish.

According to Jamieson (2010), fish oil supplementation poses the risk of over consumption of fatty acids mostly due to the fact that taking supplements does not result in a sense of satiety.

Excessive omega-3 fatty acids may result in blood in urine, nose bleeding and
hemorrhagic strokes. A study by Bruso concluded that excessive fish oil supplementation may also result in heavy metal contamination, excessive intake of vitamin A and D and omega-3 fatty acids, increased bleeding time, and slower wound healing.

It appears that the benefits of eating fish as a source of omega-3 outweigh
the benefits of taking fish oil supplements. It is safer and more effective to obtain omega-3 from eating whole fish. Fish supplements should be considered when there is a lack of fish in the diet due to allergies, or lack of availability of fish.

The next time you eat fish, remember all the good things you can get from this amazing food.
