Eating Eggs May Keep Heart Diseases Away

If you thought eating eggs is bad for your heart due to their high cholesterol content, think again. A large study has now shown that people who consume an egg every day could significantly reduce their risk of cardiovascular diseases.

People suffering from diabetes may finally eat eggs daily without a pinch of guilt. A new study suggests that eating up to 12 eggs a week does not increase cardiovascular risk factors in people with pre-diabetes or Type-2 diabetes.

If you thought eating eggs is bad for your heart due to their high cholesterol content, think again. A large study has now shown that people who consume an egg every day could significantly reduce their risk of cardiovascular diseases.

“The present study finds that there is an association between moderate level of egg consumption (up to one egg/day) and a lower cardiac event rate,” the study authors said.

The researchers pointed out that eggs are a prominent source of dietary cholesterol, but they also contain high-quality protein, many vitamins and bioactive components such as phospholipids and carotenoids.

Cardiovascular disease (CVD) is the leading cause of death and disability worldwide mostly due to ischaemic heart disease and stroke (including both haemorrhagic and ischaemic stroke).

For the study, published in the journal Heart, Chenxi Qin from Peking University Health Science Centre in Beijing, and colleagues set out to examine the associations between egg consumption and cardiovascular disease, ischaemic heart disease, major coronary events, haemorrhagic stroke and ischaemic stroke.

They used data from the China Kadoorie Biobank (CKB) study, an ongoing prospective study of around half a million (512,891) adults aged 30 to 79 from 10 different geographical areas in China.

The researchers focused on 416,213 participants who were free of prior cancer, cardiovascular disease (CVD) and diabetes.

Analysis of the results showed that compared with people not consuming eggs, daily egg consumption was associated with a lower risk of CVD overall.

In particular, daily egg consumers (up to one egg per day) had a 26 per cent lower risk of haemorrhagic stroke, a 28 per cent lower risk of haemorrhagic stroke death and an 18 per cent lower risk of CVD death.

In addition, there was a 12 per cent reduction in risk of ischaemic heart disease observed for people consuming eggs daily, when compared with the ‘never/rarely’ consumption category — about 2.03 eggs per week.

This was an observational study, so no firm conclusions can be drawn about cause and effect, but the authors said their study had a large sample size and took into account established and potential risk factors for CVD. (IANS)

Exposure to Arsenic, Lead May Spike up Risk of Heart Disease

Since metals are associated with cardiovascular disease even at relatively low levels of exposure, "population-wide strategies to minimise exposure will further contribute to overall cardiovascular prevention efforts," the researchers concluded

Even low levels of exposure to toxic chemicals in the environment like arsenic, lead, copper and cadmium pose a significant risk to cardiovascular health, finds a study, led by one of an Indian-origin.

Although often naturally occurring, these contaminants have made their way into water supplies and, via irrigation, into the food chain.

Concern has often focused on the toxicity or carcinogenic properties of the metals, particularly at high doses.

However, the findings, published by The BMJ, showed there is increasing evidence to suggest that heavy metals may have other adverse effects on health – including cardiovascular disease such as heart disease and stroke – even at lower levels of exposure, the researchers said.

“It’s clear from our analysis that there’s a possible link between exposure to heavy metals or metalloids and risk of conditions such as heart disease, even at low doses – and the greater the exposure, the greater the risk,” said lead author Rajiv Chowdhury, from Britain’s University of Cambridge.

“While people shouldn’t be overly worried about any immediate health risk, it should send a message to policymakers that we need to take action to reduce people’s exposure.”

The study “reinforces the (often under-recognised) importance of environmental toxic metals in enhancing global cardiovascular risk, beyond the roles of conventional behavioural risk factors, such as smoking, poor diet and inactivity,” the researchers said.

For the study, the team conducted a meta-analysis of 37 studies involving almost 350,000 participants.

Chowdhury noted that the study highlighted the potential need for additional worldwide efforts and strategies “to reduce human exposures even in settings where there is a relatively lower average level of exposure.”

Since metals are associated with cardiovascular disease even at relatively low levels of exposure, “population-wide strategies to minimise exposure will further contribute to overall cardiovascular prevention efforts,” the researchers concluded. (IANS)
