Minimal health risks associated with red meat consumption, Study says

Published

on

A new study by researchers in the United States suggests that there are minimal health risks associated with the consumption of red meat.

The study comes amid years of research suggesting major links between red meat consumption and health problems like heart disease, stroke, and cancer.

In a study abstract, scientists from the University of Washington’s Institute for Health Metrics and Evaluation (IHME) said the conclusions from previous research were merely observational and unable to draw out causation convincingly.

“Previous meta-analyses evaluating the effects of red meat intake have generated mixed findings and do not formally assess evidence strength,” the study reads.

“We conducted a systematic review and implemented a meta-regression—relaxing conventional log-linearity assumptions and incorporating between-study heterogeneity—to evaluate the relationships between unprocessed red meat consumption and six potential health outcomes.

“We found weak evidence of association between unprocessed red meat consumption and colorectal cancer, breast cancer, type 2 diabetes and ischemic heart disease.”

Steven Novella, Yale neurologist and president of the New England Skeptical Society, said the health risks from regular red meat consumption are almost non-existent.

“The evidence for a direct vascular or heath risk from eating meat regularly is very low, to the point that there is probably no risk,” he said.

“There is, however, more evidence for a health risk from eating too few vegetables. That is really the risk of a high-meat diet, those meat calories are displacing vegetable calories.”

Although the study acknowledged some health risks from consuming unprocessesd red meat, it said the evidence was insufficient to make general assumptions.

“While there is some evidence that eating unprocessed red meat is associated with increased risk of disease incidence and mortality, it is weak and insufficient to make stronger or more conclusive recommendations,” it reads.

“More rigorous, well-powered research is needed to better understand and quantify the relationship between consumption of unprocessed red meat and chronic disease.”

5 body changes to expect when you stop having regular sex

Published

on

By

There are certain periods when the yearn for sexual intercourse wanes and the body becomes less receptive to sexual arousal.

Almost every sex-having adult can relate to this phase.

For most, it is not a deliberate decision to withdraw from sex, rather it could be as a result of a break-up, death or disagreement, busy schedule, illness amongst other factors.

In the event of a temporary break from sex, here are five things that can happen to the human body.

Lower sex drive

When you’re not having regular sex, there is a possibility that your desire for sex reduces significantly.

Sex is associated with good feelings because the body is flooded with hormones while in the act, so when you stay away, all that energy can be directed to other activities, making sex lose its place.

“Your libido can increase your career drive and manifest more successful ambitions or, if you choose, you may direct your sexual energy into your children versus intercourse,” Fran Walfish, a Beverly Hills family and sex psychotherapist told Medical Daily.

“We can resume the same sexual drive, energy, and appetite we enjoyed before. However, don’t expect a sudden rise in libido if you never had a high sex drive.”

More stress

Sex is known to be a good way to relieve stress, therefore, a lack of regular sex can lead to elevated stress levels.

A 2005 study in Biological Psychology found that penile-vaginal intercourse is associated with better mental and physical performance, and lower stress levels.

People who hadn’t had regular sex showed higher blood pressure spikes in response to stress than those who recently had intercourse.

Less intelligent

A 2013 study discovered sex boosts neurogenesis — the creation of new neurons in the brain — and also improves cognitive function.

Sexual experiences lead to cell growth in the hippocampus, a region of the brain that’s vital to long-term memory. Therefore, sex has the potential to prevent deterioration that leads to memory loss, and dementia.

Weaker immune system

According to a 2004 study, regular sex, in moderation, can boost the immune system and make you less prone to cold.

Researchers measured levels of immunoglobulin A (IgA), an antigen found in saliva and mucosal linings, to evaluate the strength of the immune system of participants.

IgA is the body’s first line of defense against cold and flu, as it binds to bacteria that invade the body, and then activates the immune system to destroy them.

Participants who had frequent sex showed significantly higher levels of IgA than their counterparts.

Erectile dysfunction

A study published in the 2008 American Journal of Medicine discovered that men who had sex less frequently were likely to develop erectile dysfunction two times more than men who had sex frequently.

900 men in their 50s, 60s, and 70s were studied for five years and it was discovered that having sex regularly preserved potency, even at old age.

Things to know when trying to conceive at 40

Published

By

Getting pregnant at the age of 40 is probably more common than you may realise, though it is a fact that the body faces some unique challenges during pregnancy as a woman ages.

However, if you are trying to conceive at an older age, you need to be aware that even though fertility declines naturally as you age, it is possible to get pregnant after the age of 40.

If you are still having your periods, there is a chance you can get pregnant, although you have a much lower chance of conceiving naturally once you celebrate your 40th birthday than earlier in your reproductive years.

There is about five per cent chance during your menstrual cycle that you might get pregnant naturally once you are 40 years old. Compare this to a 25 per cent chance per cycle when you were in your 20s, when your fertility was at its peak.

There are many reasons for the decline in the success rate of pregnancy after 40. The rate of miscarriage is about 40 per cent after the age of 40. This can be due to many reasons, but the biggest reason is that there is a higher chance of genetic abnormality in each egg.

As a woman, your ovarian reserve also decreases over time, meaning you have fewer eggs left by the time you turn 40. The story around eggs is one that has been told several times. When you were born, your ovaries contain all the eggs that you would ever have – about a million in total. This number declines as you age because you typically lose about 30 immature eggs daily. And it’s not just you; this is what every woman of reproductive age experiences.

By the time you reach puberty, your ovaries would contain around 300,000 eggs; and by age 30, you are down to 100,000. At 40, you would have no more than 20,000 eggs left, and these are more than enough for your fertility needs.

Your ovarian reserve can be tested with a blood test called the Anti-Mullerian Hormone test. AMH is a hormone produced by the follicles in your ovaries where egg cells develop. This declines throughout your reproductive lifespan. The lower your AMH number, the fewer eggs remain in your ovarian reserve. But the AMH test result doesn’t tell anything about the quality of the remaining eggs.

The percentage of normal eggs that every woman has decreases as she ages. After age 40, the percentage of genetically abnormal eggs increases. This means that even if those eggs are fertilised, the pregnancy may not end in a live or genetically normal baby.

Clinically, at age 25, a woman has approximately 75 per cent normal eggs. By age 35, that number drops to around 45 per cent, and by 40 years, it’s around 20 to 30 per cent. This is one reason why most physicians recommend genetic testing for abnormal conditions in women pregnant after 40 years.

Besides naturally declining fertility, another challenge you can face as a woman that is over 40 is that you may have been diagnosed with other conditions which can cause pregnancy complications and/or more difficulties getting pregnant. You are at risk if you are obese, hypertensive, diabetic or have thyroid disorders, fibroids and endometriosis.

If you have other medical conditions, you should make sure your physician is aware that you are trying to conceive so that they can optimise your health appropriately to prepare for the pregnancy. A preconception counselling appointment with your regular gynaecologist can help pinpoint areas for improvement and give you personalised recommendations.

Remember that help is available if you haven’t got pregnant. Your fertility specialist can assist with fertility issues, so do not overlook a consultation with a specialist on the options available to you.

‘Smokers are liable to die young’ – This was Prof. Olatunji Aina’s submission as a keynote speaker at Vanguard’s 2nd Mental Health Summit that held on Thursday in Lagos.

The summit themed: “Mental Health in a Distressed Economy – Drug Abuse: A New Force Driving Mental Health Crises in Nigeria” brought together health experts to speak on the condition that has been referred to as a ‘silent killer’.

Prof Aina who is also a Consultant Psychiatrist identified excessive smoking as one of the conditions that could lead to mental health issues.

He said: “It has been discovered that frequent, persistent smoking can also cause mental health issues and early death.

“According to findings, smoking a stick of cigarette reduces your life by eight hours, so when you smoke three sticks, you know one day of your life is gone. And we know there are those who smoke more than three sticks in a day.

“The damage is does to one’s health cannot be overemphasised, this is why there is always a warning that comes with smoking.”

He further called for more attention to be paid to those battling mental health issues alongside improved advocacy.

Other causes of mental health issues as listed by Prof. Aina are poverty, insomnia and illnesses.
