Heavy Metals Cause Heart Disease | Heart Health Blog
Heavy Metals and Heart Disease
We all know that heart disease is a common chronic illness is the United States. In fact, it’s the number one killer. It affects the heart’s efficiency and can lead to heart attacks, stroke, and death. While you’re probably familiar with the major risk factors, including hypertension, obesity, and lack of physical activity, new research suggests another important factor may be at play as well, and that has to do with our exposure to heavy metals—something, by the way, that Jon Barron has been telling us for the last 40 years.
The study, which took place at the University of Cambridge School of Clinical Medicine in the United Kingdom, found that exposure to heavy metals including lead, arsenic, cadmium, and copper may increase the likelihood of developing cardiovascular disease or having a stroke.1 These findings are based on a meta-analysis of 37 studies that had a combined total of 348,259 subjects.
Most of the research collected and analyzed by the investigators focused on one specific heavy metal. The researchers combed through the data from the various studies, which included testing the arsenic, cadmium, copper, and lead levels present in the participants based on evaluations of blood, urine, toenail, or drinking water samples, and compared it to the volunteers’ medical records. They determined that the subjects with greater exposure to any of the four heavy metals developed cardiovascular disease more often than their peers with less exposure. Those with higher levels of lead and cadmium were additionally found to have an elevated risk of stroke.
GI, Jane. Carbohydrates with a high glycaemic index, such as bread, sugar, honey and grain-based food will give instant energy and accelerate your metabolism. If you’re trying to burn fat, stick to beans, rice, pasta, lentils, peas, soya beans and oat bran, all of which have a low GI count.
There was only one heavy metal analyzed for this study that did not have an association with an increased likelihood of cardiovascular disease, and that was mercury. However, even if mercury exposure is not a contributor to heart problems, it is certainly a danger in that it has been linked to vision loss, muscle weakness, speech impairment, and hearing loss. And truth be told, it’s a rather surprising conclusion as several studies have concluded that mercury does indeed up your risk of heart disease.23
Weightlifting for Your Heart
The research does have some flaws, including the fact that the various investigations were all conducted differently and used a range of methods to assess exposure. What’s more, the study doesn’t control for other risk factors for cardiovascular disease such as obesity and smoking, so we don’t know to what extent other behaviors may be influencing the outcomes.
With that said, the investigation does provide compelling evidence that heavy metal exposure can raise our risk of developing heart disease. And we already know that these toxins are dangerous to us in a number of ways. A 2014 study at Sapthagiri College of Engineering in Bangalore, India showed links between heavy metals and a wide range of health problems that include skin lesions, cancer, brain damage, muscle weakness, and kidney disease.4 So, to better our health on multiple fronts, lowering exposure is very important.
Take a TEA break. This not only helps keep you centered but also helps keep you hydrated. Up to 60 percent of your body is made of water, and it’s important to replenish that supply throughout the day to keep your energy up!
The problem is, these heavy metals are difficult to avoid. They have been found in our drinking water, food, and even the air we breathe. But there are ways we can lessen our exposure—or remove it once we’ve been exposed. Lead may be found in the pipes of houses built prior to 1986, and in the paint (which becomes problematic if there is chipping or wear and tear) in homes built before 1978.
You can buy a kit to test your home for lead paint on your own or call in a company that specializes in testing for lead. Lead-based paint needs to be removed by a reputable contractor with experience in this area. Your water supplier should have contaminant information on their website. You can collect samples of your water and send them to a lab for testing and, if levels are high, get filters for not just your kitchen sink but bathroom faucets and showerheads as well.
Dangers of Light Drinking
In fact, a good water filtration system can reduce your intake of arsenic, cadmium, and copper too. Also, since food can be a considerable source of heavy metals, try to limit your intake of shellfish, liver, and wine, and eat a varied diet that will limit your exposure from any one particular contaminated food. And because we are all getting some level of exposure no matter how careful we are with our choices, it is important to rid our bodies of these toxins by including a regular heavy metal cleanse in our detox regimens.
Drink more water. Most of us don’t drink enough water every day. Water is essential for our body to function. Did you know that over 60% of our body is made up of water? Water is needed to carry out body functions, remove waste, and carry nutrients and oxygen around our body. Since we lose water every day through urine, bowel movements, perspiration and breathing, we need to replenish our water intake. Since food intake contributes about 20% of our fluid intake, that means we need to drink about 8-10 glasses a day to stay hydrated.
