Heavy metal toxicity and your heart: 4 risks

Heavy metals such as lead, mercury and cadmium are known to be linked to the risk of heart disease and strokes. Here are 4 types of heavy metal toxicity that may be putting your heart health at risk.

1. Cadmium, used industrially in metal alloys, can cause kidney damage and lead to high blood pressure, blood sugar and body fat imbalances, and zinc deficiency. Eating calcium-rich foods can reduce its toxic effects.
2. Iron can promote atherosclerosis, so cutting back on iron-rich foods such as red meat may be a good idea. In one study of people who had already had a heart attack or stroke, limiting iron intake seemed to reduce the risk of a second attack. However, a reasonable intake of iron is required for vital body functions and to prevent anemia, so talk to your doctor before making any major changes to your diet.
3. Lead can be found in many places and long-term, low-level exposure has been linked to atherosclerosis, thrombosis (blood clots), high blood pressure and cardiovascular disease. If you live in an old house, make sure that the pipes are not made of lead, which could leach into the water supply. Also, be careful when redecorating – old paints often contain lead.
4. Mercury increases inflammation, promotes clotting and damages the function of arterial linings. Mercury toxicity can cause high blood pressure and cardiovascular disease and it increases the risk of strokes and heart attacks. Pregnant women should avoid eating certain types of fish that may be contaminated with high levels of mercury. Taking selenium supplements may help to reduce its toxicity.

Arming yourself with knowledge about your health and factors that can affect it is part of a proactive approach to wellness. But remember: it is always best to consult your doctor before making lifestyle changes that may have significant health implications.
