Health Dangers of Sugar

Dr. Ali Ghahary, a family doctor from Vancouver, Canada, has always been a strong advocate of healthy eating.

Something that has been long known to contribute to a decline in health is sugar. Canadians consume an overwhelming amount of sugar each year – almost 90 pounds worth! On average, males and females between the ages of 9 and 13 consume about 103 to 120 pounds of sugar – a number that increases during teenage years, up to as much as 138 pounds. The primary source of sugar consumption in the younger generation is carbonated soft-drinks. However, it can also be found in other sources such as candy, and even fruits and vegetables. Sure, sugar can taste good, but it is having harmful, even life-threatening effects on our health.

Soft-drinks are a common source of sugar

Perhaps one of the reasons why Canadians are consuming so much sugar today is because we don’t actually know how much we’re putting into our bodies. This is why in 2014, Health Canada proposed that changes be made to nutrition labels that would require companies to make it clear as to exactly how much sugar was going into packaged foods in the hope that it would deter individuals from eating unhealthy items and instead want to make healthier choices. The World Health Organization also came up with new guidelines that same year, stating that sugar should make up for less than 10 percent of our energy intake per day, which is a number that has already been far exceeded. They go on to add that if we cut that number in half to 5%, we would reap additional benefits.

Salad dressings also contain sugar, something that is usually unbeknownst to shoppers without reading nutritional labels.

Even for individuals who do strive to make healthy food choices, sugar can still be difficult to avoid. This is due in part to sugar being hidden in certain processed foods that aren’t necessarily thought of as “unhealthy” or even sweet. Ketchup, for example, contains as much as 4 grams of sugar in just one tablespoon. Salad dressing, tomato sauce, marinades, processed meats and pretzels also contain sugar. It is even found in infant formula.

One of the main reasons why sugar should be avoided is because it contains calories and does not have any essential nutrients. In fact, excessive intake of sugar can actually lead to nutrient deficiencies. Sugar is also high in fructose, which can cause a multitude of health problems. While it may not be an issue if we only consume a small amount (from a fruit, for example) or exercise regularly…if fructose overloads the liver, it is then turned into fat. Sugar can also cause insulin resistance, which causes problems with glucose (blood sugar.) Too much glucose can be toxic, and is one of the biggest reasons for complications from diabetes. Individuals who consume more beverages containing sugar, such as soda, are 85% more likely to develop Type II diabetes. According to multiple studies, sugar has also been thought to contribute to cancer – one of the leading causes of death worldwide – as it feeds cancer cells. In addition to all of these health problems, sugar also leads to cavities, feeds candida (yeast), can lead to osteoporosis, contributes to heart problems and ulcers, can cause arthritis, and promotes the aging of skin.

How to Prevent Kidney Stones

In yesterday’s articles we discussed how the kidneys function. Today, we are going to continue that conversation by discussing kidney stones, how they occur, the symptoms associated to them, and how they can be treated.

Kidney Stones
Kidney Stones

Kidney stones form as a result of your urine containing (and being unable to dilute) crystal-forming substances such as calcium, oxalate and uric acid. In addition, your urine may also lack the substances that prevent these crystals from forming, which then creates an ideal environment for kidney stones to develop. While kidney stones do not have one definitive cause, there are several factors that can increase your risk of developing kidney stones. These risk factors include having a family history of kidney stones, dehydration, having an unhealthy diet, obesity, digestive disorders and other medical conditions such as metabolic disorders, which can increase the concentration of calcium or oxalate found in urine.

An individual suffering from kidney stones usually presents with severe pain in the back that can spread to the abdomen, nausea and vomiting, painful urination, and urine that is cloudy and/or has a foul odor. It is also not unusual for pain to fluctuate in intensity.

There are three different types of kidney stones:

1. Calcium Stones
Calcium oxalate is a naturally occurring substance that is found in certain foods such as fruits and vegetables, nuts and chocolate. Your liver also produces oxalate.

2. Struvite Stones
These kinds of kidney stones are formed as a result of an infection, such as a UTI (urinary tract infection). Struvite stones can grow rapidly and become large. These stones sometimes come on with little warning and have very few symptoms.

3. Uric Acid Stones
Uric acid stones can form in individuals who are not drinking enough fluids or are losing too much fluid, in individuals who have diets that are high in protein, as well as individuals diagnosed with gout. There are also generic factors that may increase the risk of uric acid stones.

For individuals prone to developing kidney stones, Vancouver physician Dr. Ali Ghahary suggests controlling the intake of foods that are high in calcium and oxalate such as beets, chocolate, tea, coffee, cola, nuts, strawberries, and spinach.

For prevention of kidney stones, HealthLink BC also recommends drinking 10 to 12 cups of water per day and eating foods that come from plant-based protein sources such as dried lentils, peas, beans and tofu. You should also limit packaged foods and replace salt with things like herbs, lemon or lime zest/juice, garlic and ginger – and absolutely avoid alcohol! You should also use caution when taking calcium supplements as they can also lead to an increased risk of kidney stones.

While kidney stones are usually passed through urination (something that can cause severe discomfort), depending on the size and location of the stones you may require a procedure known as ESWL (Extracorporeal Shock Wave Lithotripsy). This procedure uses sound wave vibrations to break the stones into tiny fragments, making them easier to pass in your urine. If this is unsuccessful, surgery may then be required.

If you would like more information on kidney stones, you can connect with Dr. Ali Ghahary on social media platforms such as Twitter  at http://twitter.com/dralighahary, and Linkedin.

For any questions you have about kidney stones, or if you suspect you may have kidney stones, Dr. Ali Ghahary is available to see walk-in patients every Monday and Wednesday from 2 PM to 8 PM, Fridays from 12 PM to 4 PM, and Sundays from 1 PM to 6 PM. Hours are dependent on patient volume, so make sure you take a look at the clinic’s walk-in schedule and contact them to ensure they are still accepting patients on the day you choose to attend.

How the Kidneys Function

The kidneys – two fist-sized, bean-shaped organs that are located just below the ribcage – are responsible for removing any excess fluid or waste from the body, in addition to keeping electrolyte levels stable and creating hormones that make red blood cells, regulate blood pressure, and even help make your bones strong.

First, we’ll take a look at how the kidneys function…

Each kidney is made up of filtering units known as nephrons that filter small amounts of blood. The nephrons include their own filter known as the glomerulus which allows waste to pass through it, with the final product turning into urine. Urine flows from the kidneys to the bladder through two thin tubes located on each side of the bladder known as ureters. The kidneys filter approximately 150 quarts of blood each day, producing 1 to 2 quarts of urine. When our kidneys don’t work properly, the production of urine can slow down and even stop completely, resulting in kidney failure and the need for kidney dialysis to help with the removal of leftover fluid from the body.

Kidney failure can occur from a number of acute or chronic situations. For example, if you have suffered direct damage to your kidneys, have been diagnosed with a condition that can significantly slow down blood flow to the kidneys, or blocked ureters where waste is unable to leave your body. Conditions that can slow blood flow and lead to kidney failure include blood loss, heart attack or heart disease, infections, liver failure and dehydration. Certain diseases, damage and other agents such as blood clots, lupus, and multiple myeloma can also lead to acute kidney failure, as well as toxins such as alcohol and drug use. You are at a greater risk of developing kidney failure if you are at an advanced age, have been diagnosed with heart failure, liver disease or peripheral artery disease. With acute kidney failure, the function of the kidneys is lost rapidly. However, for acute kidney failure to occur, both kidneys must be damaged. If only one kidney is damaged, it can be removed and you will still be able to have normal function with the remaining kidney. If both kidneys are damaged then a kidney transplant may be required.

It is important to note that acute kidney failure usually co-occurs with other medical conditions, both of which can rapidly worsen if not appropriately treated, hence why it is important to see your physician for annual checkups.

Dr. Ali Ghahary, who practices in the city of Vancouver, is available to see patients on a walk-in basis and is happy to answer any questions you may have about the kidneys and how they function.

February is Heart Month in Canada

Heartbeat - Dr. Ali Ghahary

Heart Month, created by the Heart and Stroke Foundation, is a campaign to raise awareness on heart disease and promote positive lifestyle changes to lessen the risk of patients developing heart disease or suffering from a stroke.

At least 9 in 10 Canadians over the age of 20 have at least one risk factor for developing heart disease, and an estimated 600,000 Canadians are currently living with heart failure. While there is no cure for heart failure, there are many steps a person can take to manage the condition, and other changes one can make to avoid the development of heart failure later in life, as 8 in 10 cases of heart disease and stroke are preventable by making simple lifestyle and behaviour changes.

If you are a smoker, consume alcohol, are physically inactive, have high blood pressure or high cholesterol, you are at an increased risk of developing heart disease. As many as 14 million Canadians are obese or overweight, and more than 2 million Canadians have been diagnosed with diabetes, with prevalence on the rise.

Eating well is a key factor in keeping your heart healthy. Instead of eating over-processed food such as pizza, hot dogs, and deli meats, choose foods that are natural. Fruits and vegetables, for example, carry lots of nutrients such as vitamins, minerals, fibre and antioxidants, and you should eat 7 to 10 servings each day.

Dr. Ali Ghahary, a physician in Vancouver, is a strong advocate for healthy eating and healthy lifestyles, and you can find diet-specific information by visiting https://alighahary.wordpress.com. In addition to eating more fruits and vegetables, you should also try to consume whole grain foods rather than refined grains such as pasta or white bread. Whole grain foods such as brown rice, quinoa and hulled barley contain fibre, vitamin B, and protein. Other foods containing proteins include beans, lentils, fish, tofu, lean meat, and certain dairy products that are lower in fat. Making a meal plan by writing down a list of foods and recipe ideas may be helpful, and you should always read the nutrients facts found on packaging to know how much salt, sugar or trans fat you may be consuming. If you like to snack, instead of eating potato chips try alternatives such as celery, cucumbers, carrots, or grape tomatoes – these go great with low-fat dips, salsa, hummus or peanut butter.

Physical activity is also important in maintaining heart health. By exercising 150 minutes per week, you are not only preventing heart disease and stroke, but you will also be lowering your cholesterol as well as avoiding diabetes, osteoporosis, and certain types of cancer. You will also notice benefits quickly; blood pressure will improve, and you will feel much more energetic as a result of staying physically fit.
