Father's Diet May Impact the Son's Ability to Reproduce

February 17, 2017

Feb 17: A healthy diet is the king. It can save you from various ailments and slow down signs of ageing. The times we live in, there are all sorts of processed food products available in the market which are delicious no doubt but come loaded with chemicals and unwanted calories that adversely affect our health. It is therefore essential to choose right and eat mindfully.

FDietHow you eat doesn't only affect your health at present and in the future, but could have implications on your future offspring. Research suggests that it's not only genetic materials that get passed on from parents to offspring, but other traits too. One's diet plays a crucial role too. A healthy diet has various repercussions that may not be evident at the moment but it shows results in the future. So from father to son, there's not just the passing on of genes but more.

A recent study done by Monash University in Melbourne, Australia, states that a father's high-protein diet may increase the son's ability to reproduce. The study which was published in the journal Biology Letters says that a father's diet can affect the son's ability to out-compete a rival's sperm after mating.

The study highlighted the importance of the paternal environment on future generations, even long time before offspring were produced, said one of the lead authors of the study, Susanne Zajitschek.

The study sought to understand if the nutritional history of fathers had an effect on their sons. Experiments were carried out in the fruit fly, which shares many similar pathways and characteristics with human genes.

"Our study found that males that were raised on either high or low protein diets, but spent their adulthood on an intermediate diet, produced sons that had large differences in gene expression, which most likely contributed to the resulting differences in sperm competitiveness," Zajitschek said.

"They differed in their ability to sire offspring, with the high-protein dads producing sons who were doing much better in sperm competition, which means their sperm was more likely to win against a competitor's sperm within the female tract," Zajitschek said

The COVID-19 pandemic and the subsequent lockdown saw many people turning chefs overnight, but those who could not turned to online delivery of food. And not just any food, as per a new report, Indians "craved the most for Biryani" during the lockdown.

The "StatEATistics report: The Quarantine Edition" from food delivery platform Swiggy found that Indians ordered biryani over "5.5 lakh times" from their favourite restaurants.

The new normal might have opened a pandora's box of behavioral changes, but some old habits die hard like the love for Biryani, which took the top spot for overall orders. It was followed by butter naan and masala dosa at 3,35,185 and 3,31,423, respectively.

Biryani has topped the list of most ordered dishes for the fourth year in a row, the food delivery platform noted.

Indians didn't forget to indulge their sweet tooth in the uncertain months of lockdown. Their favourite comfort food during the lockdown period was the moist and decadent Choco Lava cake, ordered around 1,29,000 times.

"The humble Gulab Jamun (84,558) and chic Butterscotch Mousse cake (27,317) followed suit," said the report derived from Swiggy's order analysis in the past few months across cities that it is present in.

Also, as birthday parties moved to video calls, and virtual cake cutting sessions, according to the food delivery platform, it delivered nearly "1,20,000 cakes" to complete these celebrations.

According to the report, on average, "65,000 meal orders" were placed by 8 pm each day to make sure food arrived in time for dinner.

"It was the busiest hour for Swiggy delivery partners and restaurants. On average, they (customers) chose to tip Rs.23.65, with one particularly generous customer tipping Rs. 2500!," it added.

For those who only relied on home-made food during the quarantine, Swiggy delivered a whooping 323 million kgs of onions and 56 million kgs of bananas through its grocery section and hence ensured that its consumers were all stocked up.

That said, it also took care of the 'quick-fix meal' tribe -- consumers who resort to the evergreen college hacks of living on instant noodles.

"Around 3,50,000 packets of this ideal easy to cook meal were ordered during the lockdown," it said.

In all, Swiggy delivered 40 million orders across food, groceries, medicines and other household items during India's lockdowns. It also delivered over 73,000 bottles of sanitizers and hand wash along with 47,000 face masks as the definition of essentials' changed during these uncertain times.

Despite tremendous advances in treatment of congenital heart disease (CHD), a new global study shows that the chances for a child to survive a CHD diagnosis is significantly less in low-income countries.

The research revealed that nearly 12 million people are currently living with CHD globally, 18.7 per cent more than in 1990.

The findings, published in The Lancet, is drawn from the first comprehensive study of congenital heart disease across 195 countries, prepared using data from the Global Burden of Diseases, Injuries and Risk Factors Study 2017 (GBD).

"Previous congenital heart estimates came from few data sources, were geographically narrow and did not evaluate CHD throughout the life course," said the study authors from Children's National Hospital in the US.

This is the first time the GBD study data was used along with all available data sources and previous publications - making it the most comprehensive study on the congenital heart disease burden to date.

The study found a 34.5 per cent decline in deaths from congenital disease between 1990 to 2017. Nearly 70 per cent of deaths caused by CHD in 2017 (180,624) were in infants less than one year old.

Most CHD deaths occurred in countries within the low and low-middle socio-demographic index (SDI) quintiles.

Mortality rates get lower as a country's Socio-demographic Index (SDI) rises, the study said.

According to the researchers, birth prevalence of CHD was not related to a country's socio-demographic status, but overall prevalence was much lower in the poorest countries of the world.

This is because children in these countries do not have access to life saving surgical services, they added.

"In high income countries like the United States, we diagnose some heart conditions prenatally during the 20-week ultrasound," said Gerard Martin from Children's National Hospital who contributed to the study.

"For children born in middle- and low-income countries, these data draw stark attention to what we as cardiologists already knew from our own work in these countries -- the lack of diagnostic and treatment tools leads to lower survival rates for children born with CHD," said researcher Craig Sable.

"The UN has prioritised reduction of premature deaths from heart disease, but to meet the target of 'ending preventable deaths of newborns and children under 5 years of age,' health policy makers will need to develop specific accountability measures that address barriers and improve access to care and treatment," the authors wrote.

The Union health ministry on Friday revised the dosage of anti-viral drug remdesivir to be administered to coronavirus patients in the moderate stage of illness from the earlier six days to five days as it issued an updated 'Clinical Management Protocols for COVID-19'.

The drug, administered in the form of injection, should be given at a dose of 200 mg on day one followed by 100 mg daily for four days (total five days), the new treatment protocols stated.

The Health Ministry on June 13 had allowed the use of remdesivir for restricted emergency use in moderate cases under "investigational therapies".

"Under emergency use authorisation, remdesivir may be considered for patients in moderate stage requiring oxygen support," the document stated.

It is not recommended for those with severe renal impairment and high level of liver enzymes, pregnant and lactating women, and those below 12 years, it said.

The ministry also okayed off-label application of tocilizumab, a drug that modifies the immune system or its functioning, and convalescent plasma for treating COVID-19 patients in the moderate stage of illness as "investigational therapies".

It also recommended hydroxychloroquine for patients during the early course of the disease and not for critically-ill patients.

On June 27, the ministry had included an inexpensive, widely used steroid dexamethasone in treatment protocols for COVID-19 patients in the moderate to severe stages of their illness among other therapeutic measures.

The ministry advised use of dexamethasone, which is already used in a wide range of conditions for its anti-inflammatory and immunosuppressant effects, as an alternative choice to methylprednisolone for managing moderate to severe cases of coronavirus infection.

India's COVID-19 cases soared by over 20,000 in a day for the first time taking the country's total tally to 6,25,544 on Friday while the death toll climbed to 18,213 with 379 new fatalities, according to the Union Health Ministry data updated at 8 am.
