Trouble is brewing for coffee lovers in California, where a judge ruled that sellers must post scary warnings about cancer risks. But how frightened should we be of a daily cup of joe? Not very, some scientists and available evidence seem to suggest.
Scientific concerns about coffee have eased in recent years, and many studies even suggest it can help health.
“At the minimum, coffee is neutral. If anything, there is fairly good evidence of the benefit of coffee on cancer,” said Dr. Edward Giovannucci, a nutrition expert at the Harvard School of Public Health.
The World Health Organization’s cancer agency moved coffee off the “possible carcinogen” list two years ago, though it says evidence is insufficient to rule out any possible role.
The current flap isn’t about coffee itself, but a chemical called acrylamide that’s made when the beans are roasted. Government agencies call it a probable or likely carcinogen, based on animal research, and a group sued to require coffee sellers to warn of that under a California law passed by voters in 1986.
The problem: No one knows what levels are safe or risky for people. The U.S. Environmental Protection Agency sets acrylamide limits for drinking water, but there aren’t any for food.
“A cup of coffee a day, exposure probably is not that high,” and probably should not change your habit, said Dr. Bruce Y. Lee of Johns Hopkins Bloomberg School of Public Health. “If you drink a lot of cups a day, this is one of the reasons you might consider cutting that down.”
Here’s what’s known about the risks.
Start with the biggest known risk factor for cancer — smoking — which generates acrylamide. In the diet, French fries, potato chips, crackers, cookies, cereal and other high-carbohydrate foods contain it as a byproduct of roasting, baking, toasting or frying.
Food and Drug Administration tests of acrylamide levels found they ranged from 175 to 351 parts per billion (a measure of concentration for a contaminant) for six brands of coffee tested; the highest was for one type of decaf coffee crystals. By comparison, French fries at one fast-food chain ranged from 117 to 313 parts per billion, depending on the location tested. Some commercial fries had more than 1,000.
Even some baby foods contain acrylamide, such as teething biscuits and crackers. One brand of organic sweet potatoes tested as having 121 parts per billion.
What’s the risk?
The “probable” or “likely” carcinogen label is based on studies of animals given high levels of acrylamide in drinking water. But people and rodents absorb the chemical at different rates and metabolize it differently, so its relevance to human health is unknown.
A group of 23 scientists convened by the WHO’s cancer agency in 2016 looked at coffee — not acrylamide directly — and decided coffee was unlikely to cause breast, prostate or pancreatic cancer, and that it seemed to lower the risks for liver and uterine cancers. Evidence was inadequate to determine its effect on dozens of other cancer types.
Since 1986, businesses have been required to post warnings about chemicals known to cause cancer or other health risks — more than 900 substances are on the state’s list today — but what’s a “significant” risk is arguable.
Sellers and other defendants in the lawsuit that spurred Thursday’s ruling have a couple of weeks to challenge it or appeal.
The International Food Information Council and Foundation, an organization funded mostly by the food and beverage industry, says the law is confusing the public because it doesn’t note levels of risk, and adds that U.S. dietary guidelines say up to five cups of coffee a day can be part of a healthy diet.
Dr. Otis Brawley, the American Cancer Society’s chief medical officer, said, “The issue here is dose, and the amount of acrylamide that would be included in coffee, which is really very small, compared to the amount from smoking tobacco. I don’t think we should be worried about a cup of coffee.”
Amy Trenton-Dietz, public health specialist at the University of Wisconsin-Madison, said the California ruling contrasts with what science shows.
“Studies in humans suggest that, if anything, coffee is protective for some types of cancer,” she said. “As long as people are not putting a lot of sugar or sweeteners in, tea and water are the best things for people to be drinking.” VOA
The Supreme Court on Tuesday agreed to examine a seeking direction to the Election Commission to de-register a political party, which fails to comply with the court's direction to disclose criminal antecedents of candidates fielded in polls. Advocate Ashwini Upadhyay requested a bench headed by Chief Justice N.V. Ramana and comprising Justices A.S. Bopanna and Hima Kohli to list the petition urgently, against the backdrop of the ongoing election process. He contended that nomination for the first phase of the Uttar Pradesh Assembly election has started, and the political parties and candidates are brazenly violating the top court judgments.
After briefly hearing Upadhyay, the bench said: "We will consider it... will give a date".

The plea claimed that the cause of action for filing the plea arose after the Samajwadi Party fielded alleged gangster Nahid Hasan from Kairana but neither published his criminal records in electronic, print and social media nor the reason for his selection within 48 hours. On February 13, last year, Shamli police imposed the Gangster Act on Nahid Hasan, who is a two-time MLA from Kairana. "He (Hasan) has multiple criminal cases and is the 'mastermind' behind the Hindu exodus from Kairana. There are many criminal cases including fraud and extortion, and he was declared a fugitive by Special MLA-MP Court," the plea said.
The plea argued that the consequences of permitting criminals to contest and become legislators are extremely serious for democracy and secularism. The plea sought a direction to the Election Commission to take steps to ensure that every political party publishes the details regarding criminal cases of each candidate along with the reason for such selection on the homepage of its official website in bold letters within 48 hours in the spirit of top court orders passed on September 25, 2018, and February 2, 2020.

There will be no chief guest at the Republic Day parade this year also as the plan to host state heads of five Central Asian countries -- Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan -- seems to have been cancelled due to the Covid situation in India as well as in the respective nations. Though the Ministry of External Affairs is yet to confirm this officially.
If the guests arrive, then this would be the second time when India hosts a group of state heads as the chief guests on the Republic Day. In 2018, state heads of ASEAN countries graced the occasion with their presence. Apart from Kazakhstan, none of these countries' state heads had been invited as the chief guests on the Republic Day. In 2009, Kazakhstan's then president Nursultan Nazarbayev was the Chief Guest.

As per sources, due to the corona situation, the Government of India is in no mood to take any risk to invite any foreign guest, so the plan seems to have been cancelled. Last year, British Prime minister Boris Johnson was invited for the same, but later cancelled due to rising corona cases in the UK.
In the past, there have been occasions when the Republic Day ceremony was celebrated without any foreign guest. In 1966, there was no foreign chief guest in the Republic Day parade ceremony as the then Prime Minister Lal Bahadur Shastri had passed away in Tashkent in January, and Indira Gandhi took oath as Prime Minister on January 24.

A team of scientists from the Banaras Hindu University (BHU) have found a cure for those suffering from chronic wounds, particularly with diabetic foot ulcers. The team led by Prof Gopal Nath of the department of Microbiology, Institute of Medical Sciences, said that wounds that took months and years to heal, could now be cured in days or months. The findings of study have been published in the National Centre for Biotechnology Information, National Institutes of Health, US.
Prof Nath said that a wound is defined as a breach in the skin or body tissues due to injury. An acute wound is defined as a "recent break that is yet to progress through sequential stages of healing". The wounds where normal healing process is stalled due to underlying pathology (vascular and diabetes) or infection beyond three months is defined as chronic wound. While chronic wounds always get infected, the contaminated wounds are reasonably susceptible to infection.

Infection with antibiotic-resistant bacteria and biofilm formation halt healing progress. These wounds cause significant psychological and physical morbidity. The traditional treatment strategies often succeed in healing wounds, he said adding that many wounds have been observed recalcitrant to them, leading to persistence and recurrent infections. Search for alternatives to antibiotics has now become a compulsion. Fortunately, bacteriophage therapy is a re-emerging solution to antibiotic-resistant bacteria.
Prof Nath's team carried out phage therapy of acute and chronic infected wounds in animals and clinical studies. It showed efficacy against Pseudomonas aeruginosa in a mice wound model. Furthermore, they evaluated the efficacy of phage cocktails in animal models' acute and chronic osteomyelitis caused by methicillin-resistant Staphylococcus aureus. They also observed biofilm eradication from K wire in rabbits' wound infection model. Clinical trials of phage therapy initiated by the BHU have reported the efficacy of topical phage in healing chronic wounds in three prospective exploratory studies and no adverse events mimicking the results in vivo animal models.

A clinical study by Gupta demonstrated the significant role of bacteriophage therapy in the chronic wounds associated with antibiotic-resistant bacteria. The study employed a total of twenty patients with chronic non-healing ulcers for more than six weeks duration. A significant improvement could be achieved in the form of complete wound epithelization within a few weeks. Another study, employing 48 patients having a minimum of one eligible full-thickness wound that did not heal in six weeks with convention wound management, showed the promising result, and significant improvement was observed in the wound healing.
The study projected that specific phage therapy is equally effective regardless of the diabetic or non-diabetic status of the patient though the healing was relatively delayed in diabetic patients. Another successful study has shown encouraging results on healing process of infected acute traumatic wounds. The average number of days required for complete granulation of wounds and attaining sterility and healing was half compared to conventional therapy. (IANS/SP)
