New York, July 11 (IANS) Drinking one or more cups of coffee per day was associated with about a 10 per cent decrease in risk of Covid-19, compared to less than one cup daily, claimed a study.
The study, led by researchers from the Northwestern University in the US, also found that the consumption of more vegetables, and less processed meats, could cut the risk of Covid infection.
Coffee is known to contain antioxidant and anti-inflammatory properties.
"Coffee consumption favourably correlates with inflammatory biomarkers such as CRP, interleukin-6 (IL-6), and tumour necrosis factor I (TNF-I), which are also associated with Covid-19 severity and mortality," said the study published in the journal Nutrients.
"Coffee consumption has also been associated with lower risk of pneumonia in elderly. Taken together, an immunoprotective effect of coffee against Covid-19 is plausible and merits further investigation," it added.
For the study, the team analysed the records of 40,000 British adults in the UK Biobank. They looked at the link between diet factors including daily intake of coffee, tea, oily fish, processed meat, red meat, fruit, and vegetables, and Covid.
They found that consumption of at least 0.67 servings/d of vegetables (cooked or raw, excluding potatoes) was associated with a lower risk of Covid-19 infection.
Processed meat consumption of as little as 0.43 servings/d was associated with a higher risk of Covid-19. However red meat consumption presented no risk, suggesting meat per se does not underlie the association observed with processed meats.
"Our results support the hypothesis that nutritional factors may influence distinct aspects of the immune system, hence susceptibility to Covid-19. Encouraging adherence to certain nutritional behaviours (eg, increasing vegetable intake and reducing processed meat intake) may be an additional tool to existing Covid-19 protection guidelines to limit the spread of this virus," said the researchers.
"Although these findings warrant independent confirmation, adherence to certain dietary behaviors may be an additional tool to existing Covid-19 protection guidelines to limit the spread of this virus," they added.
New Delhi, May 31 (IANS) A three-judge bench of the Supreme Court on Monday remarked, "You must smell the coffee", as it grilled the Centre over its vaccine policy and emphasised that the policy to fight back the deadly virus should be aligned with the ground situation in the country.A bench comprising Justices D.Y. Chandrachud, L. Nageswara Rao and S. Ravindra Bhat told Solicitor General Tushar Mehta, representing the Centre, "You must smell the coffee and see what is happening across the country", and stressed that Centre's vaccination policy should not be carved in stone, rather it should evolve based on the ground situation. The bench suggested that the Centre must know the ground situation and change its policy accordingly. "If we had to do it, we would have done it 15-20 days back. If we had to do, we would have done so 15 days ago. But we want you to smell the coffee and realise what is happening in the country and make the necessary amendments.", said the bench.The bench emphasised that the vaccination not reaching the rural population and indicated that 75 per cent vaccination is being done in urban areas. "With shortage there is no chance of vaccine going in rural areas," the bench noted.Justice Chandrachud noted that private hospitals, procuring the vaccines, are not serving the core rural areas, therefore the Centre is merely addressing urban areas. "The policy today does not include vaccination in rural areas, it is a matter of concern," noted the bench.Justice Chandrachud emphasised the policy cannot be ad-hoc day-to-day response, instead there should a plan based on science. "We want the policy to be amended..need enforceable policies for the country. You have to have a policy to deal with these issues. If a new issue comes up then policy has to address it", said the bench. Citing technical glitches on CoWIN application used for registration for vaccinations, Justice Bhat said he had received distress calls from all over the country, and added that young people, who had registered for vaccination, visit private hospitals, only to find all slots are booked. Making it clear that its suggestion on vaccine policy should be taken in the right stride, the bench said "We are not going to run central govt and make policies for you." On the aspect of vaccine policy, Justice Chandrachud told Mehta that the ability to recognise that 'I am wrong' is not a sign of weakness, but that of strength.He added that this is a platform for dialogue across the spectrum. "The idea is not to criticise, but to strengthen the arms of the government..The fact that MEA went abroad, had dialogue shows the seriousness of the situation", said Justice Chandrachud. During the top court's suo motu hearing on Covid-19 crisis management in the country, the Centre informed the top court that it is confident of vaccinating all eligible persons over 18 years, by the year end. Mehta submitted the production from domestic vaccine producers will be enough to vaccinate all who are over 18 years of age. --IANS ss/ash
New York, Coffee pulp, a waste product of coffee production, could be used to speed up tropical forest recovery on post agricultural land, suggests a new study.
In the study published in the journal 'Ecological Solutions and Evidence', the team spread 30 dump truck loads of coffee pulp on a 35-40m area of degraded land and marked out a similar sized area without coffee pulp as a control.
"The results were dramatic", said lead researcher Rebecca Cole from the University of Hawai'i in the US.
"The area treated with a thick layer of coffee pulp turned into a small forest in only two years while the control plot remained dominated by non-native pasture grasses," Cole added.
After only two years, the coffee pulp treated area had 80 percent canopy cover compared to 20 percent in the control area. The canopy in the coffee pulp area was also four times taller than that of the control area.
The addition of the half metre thick layer of coffee pulp eliminated the invasive pasture grasses which dominated the land.
These grasses are often a barrier to forest succession and their removal allowed native and pioneer tree species, that arrived as seeds through wind and animal dispersal, to recolonise the area quickly.
The researchers also found that after two years, nutrients, including carbon, nitrogen and phosphorous, were significantly elevated in the coffee pulp treated area compared to the control.
For the study, the researchers analysed soil samples for nutrients immediately prior to the application of the coffee pulp and again two years later.
They also recorded the species present, the size of woody stems, percentage of forest ground cover and used drones to record canopy cover. (agency)
Barcelona, March 23 (IANS) Caffeine -- about 3 milligram per kilogram (mg/kg), the equivalent of a strong coffee -- ingested half an hour before aerobic exercise significantly increases the rate of fat-burning, suggests a new study.The study, published in Journal of the International Society of Sports Nutrition, also found that if the exercise is performed in the afternoon, the effects of the caffeine are more marked than in the morning."The results of our study showed that acute caffeine ingestion 30 minutes before performing an aerobic exercise test increased maximum fat oxidation during exercise regardless of the time of day," said lead researcher Francisco Jose Amaro-Gahete from the University of Granada in Spain.For the study, the researchers aimed to determine whether caffeine -- one of the most commonly-consumed ergogenic substances in the world to improve sports performance -- actually does increase oxidation or "burning" of fat during exercise. A group of men with a mean age of 32 participated in the research, completing an exercise test four times at seven-day intervals. Subjects ingested 3 mg/kg of caffeine or a placebo at 8 am and 5 pm (each subject completed the tests in all four conditions in a random order). The conditions prior to each exercise test (hours elapsed since last meal, physical exercise, or consumption of stimulant substances) were strictly standardized, and fat oxidation during exercise was calculated accordingly.In summary, the findings of this study suggest that the combination of acute caffeine intake and aerobic exercise performed at moderate intensity in the afternoon provides the optimal scenario for people seeking to increase fat-burning during physical exercise.--IANSvc/pgh
Sydney- If you drink a lot of coffee throughout the day, it can increase the risk of cardiovascular diseases (CVD), a new study suggests.
The findings, in a genetic-based study, indicate that long-term, heavy coffee consumption -- six or more cups a day -- can increase the amount of lipids (fats) in your blood to significantly heighten your risk of CVD.
Importantly, this correlation is both positive and dose-dependent, meaning that the more coffee you drink, the greater the risk of CVD, the researchers, including Elina Hyppönen from the University of South Australia said.
"There's certainly a lot of scientific debate about the pros and cons of coffee, but while it may seem like we're going over old ground, it's essential to fully understand how one of the world's most widely consumed drinks can impact our health," said Hyppönen.
For the study, published in Clinical Nutrition, the team used data from 362,571 UK Biobank participants, aged 37-73 years, using a triangulation of phenotypic and genetic approaches to conduct comprehensive analyses.
While the jury may still be out on the health impacts of coffee, the researcher said it is always wise to choose filtered coffee when possible and be wary of overindulging, especially when it comes to a stimulant such as coffee.
According to the researchers, high levels of blood lipids are a known risk factor for heart disease, and interestingly, as coffee beans contain a very potent cholesterol-elevating compound (cafestol), it was valuable to examine them together.
"Cafestol is mainly present in unfiltered brews, such as French press, Turkish and Greek coffees, but it's also in espressos," said Hyppönen.
Globally, an estimated 3 billion cups of coffee are consumed every day. CVD are the number one cause of death globally, taking an estimated 17.9 million lives each year. (IANS)
Tokyo, Feb 4 (IANS) Drinking green tea may help reduce multiple causes of death and prevent further cardiovascular problems among stroke and heart attack survivors, a new study suggests.The research, published in the journal Stroke, also found daily coffee consumption helps heart attack survivors by lowering their risk of death after a heart attack and can prevent heart attacks or strokes in healthy individuals."There is a strong need for scientific evidence on the lifestyles among survivors of stroke and heart attack considering the rapidly aging population and the need to improve life expectancy following these cardiovascular events," said researcher Hiroyasu Iso, Professor at Osaka University in Suita, Japan.For the study, the researchers analyzed data of more than 46,000 participants (aged 40 to 79 with 60 per cent being females). Participants were then divided into three groups -- history of stroke; history of myocardial infarction (MI); and no history of stroke or MI. The team then analyzed the amount and frequency of green tea and coffee consumption.When compared with participants who rarely drank green tea, stroke survivors who consumed at least seven cups of green tea daily lowered their risk of all-cause mortality by approximately 62 per cent. Heart attack survivors who drank one cup of coffee a day reduced their overall risk of death by approximately 22 per cent when compared to those who did not regularly drink coffee.People without a history of stroke or heart attack who consumed one or more cups of coffee a week had approximately a 14 per cent lower risk of all-cause mortality compared to non-coffee drinkers.--IANSvc/bg
