E-cigarette users are exposed to increased concentrations of potentially harmful levels of metals that are linked to elevated oxidative DNA damage, a new study has found.

For the study, published in the journal BMJ Open Respiratory Research, researchers found that the biomarkers, which reflect exposure, effect, and potential harm, are both elevated in e-cigarette users compared to the other groups and linked to metal exposure and oxidative DNA damage.

“Our study found e-cigarette users are exposed to increased concentrations of potentially harmful levels of metals — especially zinc — that are correlated to elevated oxidative DNA damage,” said the study’s lead researcher Prue Talbot from University of California in the US.

Zinc, a dietary nutrient, plays key roles in growth, immune function, and wound healing. Too little of this essential trace element can cause death; too much of it can cause disease. Its deficiency, as well as its excess, cause cellular oxidative stress, which, if unchecked, can lead to diseases such as atherosclerosis, coronary heart disease, pulmonary fibrosis, acute lymphoblastic leukemia, and lung cancer.

Electronic cigarettes consist of a battery, atomizing unit, and refill fluid. Metals in e-cigarette aerosols come mainly from the metal components in the atomizer– nichrome wire, tin solder joints, brass clamps, insulating sheaths, and wicks — as well as the e-fluids that the atomizers heat.

For the study, researchers have examined and quantified urinary biomarkers of effect and potential harm in relation to metals in e-cigarette users.

According to the study, a biomarker is a quantifiable characteristic of a biological process. Biomarkers allow researchers and physicians to measure a biological or chemical substance that is indicative of a person’s physiological state.

Previous e-cigarette studies with humans have examined biomarkers of exposure — for example, nicotine or nicotine metabolites — but none have studied biomarkers of potential harm or shown how this harm correlates with metal exposure.

The biomarkers studied by the researchers were 8-hydroxydeoxyguanosine (8-OHdG), a biomarker of oxidative DNA damage; 8-isoprostane, an indicator of the oxidative degradation of lipids; and metallothionein, a metal response protein.

All three biomarkers were significantly elevated in e-cigarette users compared to the concentrations in cigarette smokers, the researchers said.

“Pregnant women, especially, should not be encouraged to use e-cigarettes,” Talbot said.

“Excess of zinc in their bodies can lead to nausea and diarrhea. Given the recent deaths and pulmonary illnesses related to e-cigarette usage, everyone should be made aware of the potential health risks linked to e-cigarette usage,” Talbot added. (IANS)

Vegan people follow a plant-based diet and do not eat animal products including dairy, meat, eggs, honey, and gelatin. But, veganism goes beyond the diet.

Veganism is a lifestyle that tries to bar, as far as possible and practicable, all kinds of exploitation of, and cruelty to, animals for food, or any other purpose.

Nutritionist and founder of Diet Podium, Shikha Mahajan, shares these five benefits going vegan has on your health.

Reduced risk of cancer

In 2015, the Worle Health Organisation named red meat a Group 2 Carcinogen, which means it probably causes cancer in humans. WHO placed processed meat in the Group 1 category, which means it is carcinogenic to humans.

Even small amounts of meat can increase the risk of cancer. A study from Oxford University study also found that eating just 3 rashers of bacon a day can increase cancer risk by 20 percent.

Reduced risk Of diabetes

More and more research is concluding that a plant-based diet can reduce the risk of developing diabetes or even reverse the disease completely.

A study, that included more than 2,000 adults, found those people who increased the number of fruit, vegetables, and nuts in their diet over the duration of 20 years reduced their risk of developing type 2 diabetes by 60 percent more than those who did not.

Enhanced mood

A study done by the Physicians Committee for Responsible Medicine (PCRM) shows a study on its website that looks at the eating patterns and moods of 3,486 people over a five-year period. The study showed that participants who consumed whole, plant foods reported fewer signs of depression.

A different study showed that vegetarians usually experience more positive moods than meat-eaters.

Healthy skin

A plant-based diet might boost your beauty regime by assisting your skin in staying healthy. An increasing number of studies are associating dairy to skin problems such as acne. Dairy products have growth hormones and are also sometimes infused with artificial hormones, which can disrupt the human body’s hormone system.

Fewer cardiovascular diseases

Meat generally contains a high quantity of saturated and trans-fats which can increase blood cholesterol. Cholesterol can create fatty deposits in the blood vessels that increase the risk of stroke, peripheral artery disease, and heart disease. Plant-based foods, by nature, have no dietary cholesterol. A diet high in fat and cholesterol can also lead to high blood pressure. (IANS)
