Cancer Prevention

49700193 - grandfather and grandchild

Nobody wants to have cancer, but everyone has been touched by it in some way. The good news is that research estimates that only 5-10% of cancers are hereditary, meaning that 90-95% are due to lifestyle and environmental exposures and are therefore preventable. Some exposures such as pollution in the air we breathe are difficult to avoid, but there are many other steps we can take to minimise our risk of getting cancer.

The leading cause of preventable cancer is still smoking. But I’m sure I don’t need to tell you that it is bad for you so I won’t waste words here.

After not smoking, keeping yourself at a healthy weight is the most important thing you can do to prevent cancer. Obesity actually changes your hormones, causing increased inflammation, which can lead to cancer. Now I don’t want you to start the next trend diet. Very slow (as in 1-2kg per month) weight loss is the best for keeping off the weight. And the best way to do this is to just eat well and start exercising (exercise also independently decreases your risk of cancer!).

Besides causing weight gain and diabetes, research has found that sugar is a cause of cancer in and of itself. It was estimated that “in 2010, sugary drink consumption was responsible for about 184,450 deaths worldwide, with 133,000 deaths from diabetes, 45,000 deaths from cardiovascular disease and 6,450 deaths from cancer.” Recent research has discovered a possible mechanism. When we consume excess sugar, it feeds cancer cells. Now you may say that you don’t have cancer so it doesn’t apply to you. Our bodies are constantly making cancer cells, which our immune systems usually deal with before they get out of control. But if you are consuming more sugar than your body can handle, the cancer cells may win over your immune system.

You also want to keep your digestive system and your gut flora (bacteria that live in your gut and keep you healthy) happy. Dysbiosis is when you have improper or a lack of gut bacteria and this is associated with some cancers. The best way to have a happy, healthy gut is to eat plenty of fibre-rich fruits, vegetables and legumes while minimising your intake of processed meats, which the World Health Organization has declared a cancer risk. Fibre is needed for proper digestion and can help to prevent colon cancer. You also want to eat most of your produce as organic because preservatives and pesticides can kill your friendly bacteria as well as increase your risk of ovarian and other cancers.

Although the government guidelines like to encourage everyone to drink lots of milk, data from some very large studies including the Nurses’ Health Study, has actually found an increased risk of some cancers with increased consumption. Not to mention that the Australian dietary guidelines say it is ok to drink sugar-laden flavoured milks and yogurts so that people are getting a double whammy. There are lots of other foods that contain plenty of calcium. The vegans of the worlds do not go around with rampant cases of osteoporosis.

The American Cancer Society says that half of all men and one-third of women will develop cancer in their lifetime. Don’t let yourself or your loved ones be part of this statistic. Talk to your local naturopath for advice on how to minimise your risk of cancer.


Stay Healthy This Winter (and all year long)


While it is summer for all of you in the northern hemisphere, it is winter down under which means cold and flu season has come around again. Although for those of us with kids in daycare and school it seems that cold and flu season lasts all year-round! Here are some helpful hints for keeping the whole family healthy in winter and all year long.


Sleep is the most important activity your body needs. When sleeping, your body restores, heals, and creates important hormones. Get to bed early and stay there for at least 7-8 hours each night.  Avoid caffeine to ensure you get a good quantity and quality of sleep.  Read my blog article about caffeine for more information on the effects it has on your body.

Psychological stress is associated with a greater risk of depression, heart disease and infectious diseases.[1]  Take time out – exercise, garden, meditate, whatever it is that helps you to relax.

What would one of my articles be if I didn’t mention exercise?  Exercise is important for everyone. To keep your immune system at its best you want at least a brisk 30-minute walk each day.  If you are an avid athlete you also need to take care, as very high intensity exercise can put a strain on your immune system.[2]bacteria on hands

Always wash your hands before eating.  There was a 75% reduction in flu-like symptoms when a test group wore masks and washed their hands.[3]  This is especially important for kids who are more apt to putting their hands in their mouths.  It can really be just that easy!

Our bodies are composed of 70% water. Proper hydration is important for the optimum functioning of all your body systems. Increase your water intake slowly getting up to 2L per day.  Check our my article about water for more information.

Hot-Cold showers are an excellent way of improving your immune system, increasing circula­tion and elevating energy levels. After finishing your regular shower routine, do 20 seconds of cold and 1 minute of hot. Alternate 2-3 times, ending with cold.  The increase in circulation will also help decrease sensitivity to the cold.

There are several supplements you can take to help boost your immune system. Daily zinc supplementation has been shown to shorten the duration and severity of the common cold, reduce the incidence of acute lower respiratory tract infections in preschool children by 45% and reduce the incidence of pneumonia by 41%.[4]

There are lots of herbs that can help boost your immune system.  You can check out my Cough and Cold Soother tea for a delicious mix that can help keep you healthy and fight off germs if you get sick.

Vitamin C is found in high concentrations in immune cells and is quickly consumed during an infection.  It is a natural antihistamine and has been found to reduce the severity and duration of the common cold and upper respiratory tract infections.

More than 80% of the body’s immune system is in the digestive tract.[5]  A lack of good bacteria in the digestive tract can cause a reduction in the immune system allowing increased infections.  Take a good quality probiotic to prevent bad bacteria from taking hold.

Vitamin D has a direct effect on the immune system. Vitamin D stimulates the production of natural antibiotic proteins thus killing more bacteria.  Insufficient levels are related to a deficiency in our immune system to protect us against infections.

These are just a few suggestions.  For personalized advice, contact your local naturopath. Let’s stay healthy this winter!
