Global Warming: Good News or Bad for Allergy Patients?

Photo by David Sky

Spring is the season symbolizing life and rebirth. This is a time when the flowers bloom, the birds start to sing, and when we can finally save some money by turning off the furnace. However, for many people, this is also the time of year when their troubles begin.

Springtime is when the majority of allergy patients experience symptoms such as coughing, itchy-eyes, runny-noses, and more. These symptoms are a response to our immune system fighting off allergens. Our immune system recognizes foreign objects, called antigens, in the body and react to them by producing specific antibodies, or immunoglobulin. These antibodies will attach to antigens to help destroy them. However, sometimes we develop antibodies that attach to harmless antigens, such as cat dander or pollen, and we become sensitized to these allergens and develop allergic reactions.

According to the Environment Canada weather data, the temperature in British Columbia has been on the rise. The Intergovernmental Panel for Climate Change reported that the temperature has increased by more than 0.13 degrees Celsius per decade, from 1956 to 2005. With an increase in temperature, this means that winter ends sooner, while spring starts earlier. The earlier spring allows plants to pollinate earlier than usual. Furthermore, the hotter temperatures will cause plants to release more pollen in a shorter period of time, creating an intense season where the air is saturated with pollen.

On the other hand, the pollen is released in a shorter period of time, which means a shorter time of suffering for allergy patients. Also, some allergy patients may be affected less in the warmer weather. A warmer winter means less mold in the spring, and this would be better for patients with affected by mold allergens.

Overall, I believe that it is better to have less intense allergic reactions over a longer period of time, than having severe reactions over a shorter season. To all the allergy patients out there, which would you prefer? Maybe you will make your decision while you enjoy The Allergy Song, from TheWigglesPtyLtd:

Who Needs Grit?

Many people take nutritional supplements every morning to support their health. So what about giving dietary supplements to our pets? Should we add joint supplements in the dog’s chow, vitamins to the cat’s water, or a dish of grit in the bird’s cage?

There are over 10 000 species of birds in the world. With so many different species, it is not surprising that there is a wide variation in diet. Their diet ranges from insects, seeds, fruits, nectar, and even to other birds.Birds in the wild eat a significant amount of food to fuel their caloric needs. Some of these diets are harder to digest than others, so you can imagine that these birds would need some mechanism to help grind up their food for faster digestion and absorption.

Some birds have strong beaks to crack the hard shells of insects, others use their sharp talons tear apart flesh. However, some species of birds ingest ground up minerals and sand to aid digestion. Birds in the wild consume items that are hard to digest, like seeds with hard shells. Birds grind up the seeds in their gizzards, which is a specialized organ built to grind up food. The ingested minerals and sand will help remove husks and shells from the seeds and make digestion easier.

However, should we give grit to our pet birds? Birds in captivity do not have a choice of what they eat because the owners control the diet of the pet birds. Most commercial bird foods are made for birds to easily digest and absorb, with all the essential nutrition that the bird needs. Furthermore, pet birds often do not have the freedom to fly and expend energy. They do not need grit to help speed up the absorption of nutrients. Another issue is too much grit will cause obstruction of the digestive tract. It is also important to know the content of the grit. Some grit contains charcoal, which will inhibit the absorption of certain nutrients. Below is a video of a breeder mixing his own grit for his birds.

So is it necessary to spend the extra money to buy grit for pet birds? An alternative to buying grit would be to add crushed egg or oyster shells to the bird feed. Not only do the shells help with digestion, they also provide extra calcium to the bird’s diet.

Water: The Healthiest Beverage?

There is no harm in drinking water, right?

Most of us would probably not think twice about the contents of our drinking water. The water that we get out of the tap actually contains added fluoride to help prevent tooth decay by protecting tooth enamel against acids. However, we can obtain fluoride naturally through eating various foods. Many of us may also use fluoride containing products, such as toothpastes, mouth gels, dental floss, and dietary supplements.

The Government of Canada first introduced water fluoridation in 1968. However, since then, the government has reduced the optimum level of fluoride four times. The most recent cutback was in 2008, where the optimum level was lowered to almost half the initial recommended amount in 1968.

Larger doses of fluoride may causes serious health issues, including dental fluorosis, weakened bones, or even bone cancer. Too much fluoride causes bone structure disturbances, decreases fertility, and accumulates in certain areas of the brain, which will affect behaviour and learning.

There is an ongoing debate about whether or not water fluoridation is the cause of the decline in tooth decay. However, many studies have shown that tooth decay have actually started to decline before the fluoridation of water. Furthermore, tooth decay in children who have used fluoridated water all their lives continues to decline, which means that there is probably another factor involved.

The safety level of fluoride in our drinking water remains questionable, and with so many health risks associated with excess levels of fluoride, as well as the exposure of so many fluoridated products, I believe that water fluoridation is both unnecessary and risky. Although fluoride does help prevent tooth decay, the possibility of excess fluoride intake outweighs the benefit.
