Copper Deficiency: Effects on Heart Disease

Copper Deficiency: Effects on Heart Disease

Copper is crucial for health, and its deficiency effects on heart disease are alarming. This story reminds the body needs balance! Interesting and crucial information adapted from David Watts, Ph.D., Director of Research Interclinical Laboratories).

Recently a popular news story warned that high, long term consumption of sweetened beverages such as soft drinks and soda may increase health risks. A study published in the journal Circulation (1) found that sugar sweetened beverages as well as artificially sweetened beverages were associated with mortality rates. The study consisted of over 37,000 men and over 80,000 women who were followed for over 20 years. Their conclusion found that consumption of the sugar sweetened beverage was associated primarily with cardiovascular mortality.
 
Heart Disease in Men and Women
Typically heart attacks occur more in men than women depending upon age. The average age for men having heart attacks is about 66 years compared to women whose average age is 70. Heart attacks can happen at any age and in either sex, but the rate is similar or equal in both men and women after 60 years of age. In fact, heart disease is the number one cause of death in both sexes. The study published in ‘Circulation’ also found that women fifty years and older, who consumed diet drinks had a 29% increased risk for heart attack and 23% increased risk for stroke.
 
High Fructose and Heart Disease
It seems that high fructose intake is the underlying factor in contributing to many of these statistics. The American Journal of Clinical Nutrition (2) reported that the consumption of beverages containing 10, 17.5 or 25% of fructose produced a linear dose response increase in factors contributing to cardiovascular mortality. Risk factors include, lipid and lipoprotein abnormalities, uric acid, triglycerides, cholesterol, and apolipoprotein.
 
The American Heart Association (AHA) published their recommendations for the reduction in the intake of added sugars found in soft drinks and processed foods.
 
They state in the journal Circulation that “High intakes of dietary sugars in the setting of a worldwide pandemic of obesity and cardiovascular disease has heightened concerns about the adverse effects of excessive consumption of sugars.” The mean intake for all persons was found to be over 22 teaspoons per day. However, it appears that in the age group between 14 to 18 years, consumption is about 34 teaspoons per day. High fructose corn syrup used in most sweetened beverages is playing a role in the epidemics of insulin resistance, obesity, dyslipidaemia and type 2 diabetes (3).

The Fructose Copper Connection

What is the connection between fructose and heart disease? The answer may lie in the fact that fructose is known to antagonize the mineral copper. It has been well documented that adding fructose to the diets of animals induces copper deficiency (4). Although the same has not been sufficiently studied in humans, the response of humans to a high fructose intake may be similar to response to copper deficiency caused by high intake of fructose in animals.

 Copper and Heart Health
Copper is a constituent of many important enzymes. It is involved in oxidoreductase activity, electron transport, free radical scavenging, neurotransmission as well as immunity. When it comes to heart disease copper deficiency greatly affects the functioning of the heart.  Detrimental health effects of copper deficiency include: high cholesterol, poor glucose tolerance, abnormal ECG activity, increased LDL, lowered HDL (happy lipids), and high triglycerides, increased susceptibility of lipoproteins and tissues to oxidative damage. Increased blood pressure, plasminogen activator inhibitor type I, early and advanced glycation end products, atherosclerosis, fatty liver degeneration, cardiac hypertrophy and cardiomyopathy, optic neuropathy, iron overload and connective tissue damage (5). High dietary fructose intake is associated with non-alcoholic fatty liver degeneration (NAFLD) in animal models and is thought to be due to poor copper status. Patients with NAFLD have been found to have low copper availability. Liver and serum copper levels are found inversely correlated with the severity of NAFLD (6).
 
Lee et al., (2018) reported their findings of low hair copper and its relationship to the risk of developing NAFLD. Individuals with lower hair copper concentrations were found to have higher blood pressure and increased body mass index and waist circumference and lower HDL. Those who had NAFLD were found to have significantly lower hair copper levels (7).
 
Factors Contributing to Copper Deficiency
Copper should be adequate and in proper balance with other nutritional minerals for normal copper related functions. However, an antagonistic relationship exists between copper and other nutrients that can lead to an imbalance or copper deficiency. Copper deficiency can also be caused by genetic predisposition and malabsorption conditions. Bariatric surgery can also be a major cause of acquired copper deficiency contributing to haematological and neurological symptoms (8).
 
Copper Deficiency and Cardiac Disease
A study by Kedzierska, et al, (2005), found that plasma copper concentration can significantly affect activity of the erythrocyte sodium transport system, and copper supplementation may have therapeutic benefits for hypertensive patients (9). In hair mineral testing analysis copper deficiency in patients with hypertension and metabolic syndrome can be found. Most patients with hypertension in fact show an elevated tissue of sodium and potassium concentration along with a low tissue calcium and magnesium. The benefits of copper supplementation results in an increase of copper activated free radical scavenging enzymes such as superoxide dismutase (S.O.D.) and increased availability of nitrogen oxide, along with calcium retention affects as well. An increase in tissue calcium would aid in the reduction of sodium retention and thereby reduce elevated blood pressure.
 
Heart Disease and Gender
The development of heart disease is known to differ between men and women.  However, copper imbalance may be a key factor in both. The fact that men tend to have a greater incidence of heart attacks at an earlier age than women may rest in metabolic types. Men tend to naturally be more sympathetic dominant with lower tissue copper concentrations while women tend to be more parasympathetic dominant with higher tissue copper. However, after menopause women develop heart attacks at a similar rate as men. This is due to the reduction in estrogen which often corresponds to a reduction in copper retention. Often mineral patterns of women before and after menopause show a shift in their mineral patterns from parasympathetic toward sympathetic dominance along with a lowering of copper and elevation of their zinc to copper ratio.
 
Hair Zinc and Copper Levels and Predisposition to Heart Disease
Zinc and copper concentrations were measured in the hair and urine of patients who were hospitalized for myocardial infarction (MI). Mineral concentrations were also determined in the patient’s descendants and compared to a control group who had no family history of MI. Zinc was found to be higher and copper lower in the descendants of patients with MI suggesting a consistent rise in zinc and lowering of copper reserves in genetically predisposed individuals. The study suggests that in MI patients, a genetic disorder of mineral imbalance at a younger age can be used in predicting susceptibility to heart disease in individuals prior to onset and diagnosis in asymptomatic patients (10).

Conclusion
It should also be noted that excess tissue copper can result in decreased zinc activated S.O.D. activity and thereby, may contribute to hypertension and elevated cholesterol and triglycerides as well. This biphasic effect emphasizes the need to assess individual needs and treat the patient accordingly, instead of merely treating symptoms. HTMA can be used as a screening tool for the assessment of copper status and more importantly, copper’s relationship to other nutrients.
