Of the many firsts, Japan made world's first toilet paper from used diapers. These are now sold in seven retail locations in Kagoshima Prefecture and Miyazaki Prefecture, both in Japan's Kyushu. It is an environment friendly alternative.

How Was It Carried Out?

This was done in collaboration of a team of local governments and private firms in Japan. Spearheaded by the city of Shibushi and the town of Osaki the project began in last April, as the used diapers were separated from the routine waste streams.

The two cities collected around 98 tonnes of diapers and other used hygiene products and they were then sanitized, bleached, and shredded into a pulp to be mixed with already available recycled paper. This took place at the Poppy Paper Company's plant in the Fukuoka Prefecture.

In the first batch, 30,000 rolls were created and are now sold at $2.70 per dozen. As reported in Japan's oldest English-language newspaper, the Mainichi, Satoshi Yoshida from Poppy Paper's sales department said, "This initiative could help diversify the ways to secure raw materials, especially as used paper supplies are expected to decline with the rise of paperless systems and a shrinking population."

There are other use of a recycled diapers. It can be used as an additive for concrete in place of sand as it showed increased strength in the end product. It also offers a recycled material alternative to sand that is cheaper than other market options.

Are There Any Health Concerns?

As per a 2019 study published in Reprod Toxicol, diapers contain phthalate contents, which is a group of chemicals that are used to make plastics more flexible and durable. As per a Harvard TH Chan Q&A featuring Russ Hauser, Fredrick Lee Hisaw Professor of Reproductive Physiology notes that when phthalates were studied in animal models, it was found to be anti-androgenic, which means it decreases testosterone.

Hauser also notes that prenatal exposure can also effect children's neurodevelopmental and neurobehavioral outcomes.

While recycling diapers can be beneficial, the process can be energy-intensive and require a significant water usage, as notes a 2014 study titled Treatment of the biodegradable fraction of used disposable diapers by codigestion with waste activated sludge, which could in return impact the environment.

What happens when diapers are recycled, is they undergo a special treatment that makes it possible to separate plastics and recovers the biodegradable fraction (BFD), which is made of cellulose.

The risk comes at the process of recycling, as the toxic contents like phthalates, dioxins, and fragrances that can leach out during processing and come into contact with the skin when using the recycled tissue paper, potentially causing allergic reactions, skin irritation, and endocrine disruption, especially for vulnerable populations like infants and people with sensitive skin.

There is a possibility that the superabsorbent polymer in diapers might not fully break down during the recycling process, leaving microplastics that can be inhaled or ingested when using the tissue paper.

However, with the strict quality control and ethical recycling can ensure that the process is with due diligence to ensure safety for everyone.

The Food and Drug Administration or FDA recalled cheese from one of the largest importers and distributers of specialty cheese from Italy over listeria contamination. As per FDA, seven different products have been issued a Class I recall. The recalls were initiated by The Ambriola Company's headquarters in West Caldwell, New Jersey. While the recalls were initiated at the end of November, the FDA signed classifications for the contaminated cheese on January 6.

What Is Listeria?

This is a bacterial pathogen which is responsible for listeriosis. This is a serious foodborne illness. It thrives in various environment, including soil, water, and food processing facilities and is gram-positive and rod-shaped in its nature. It can also grow at refrigeration temperature which can then infect dairy products, deli meats, seafood, and unpasteurized milk.

As per the Centers for Disease Control and Prevention (CDC(, Listeria are bacteria or germs that can contaminate many food and those who eat can get infected with the bacteria. CDC mentions that it is rare, however, could be serious, though there exists steps to prevent this infection.

It is a foodborne illness caused by the bacteria L. monocytogenes. Symptoms include fever, chills, and headache. It can cause invasive illness and intestinal illness. It is also the third leading cause of deaths from foodborne illness in the US, with 1,600 people infected each year, out of which 260 die.

Symptoms often appear within two weeks of consuming Listeria-contaminated food, but can appear as early as the same day or as late as ten weeks later.

A fever, muscle aches, and fatigue are common symptoms of pregnancy.

People who are not pregnant usually have fever, muscle aches, and tiredness. They may also get a headache, stiff neck, confusion, loss of balance, or seizures.

What Are The Different Types Of Food Contamination?

Some of the common examples could be Salmonella, E. coli, and Listeria. These microorganism can also multiply rapidly under favorable conditions, which poses health risks.

Chemical contamination

This happens when food comes in contact with chemicals which can lead to contamination. These chemicals could be of wide range, including pesticides, food additives cleaning agents, or toxins from contaminated water. Consuming chemically contaminated food can lead to acute poisoning or long term health issues.

Physical contamination

This means that foreign objects have contaminated the food, which may include glass, metal shavings, plastic or food. Often times, these contaminants find their way into food during processing and preparation.

Allergen contamination

This is could involve the unintentional transfer of food allergens. It may occur while using a share equipment, utensils, surfaces, or airborne particles that makes the food unsafe.

In a recent episode of Soha Ali Khan’s YouTube podcast 'All About Her', actor Genelia D'Souza told viewers that she does not feed her children ghee over fears of blocking their arteries and causing heart damage.

She told Khan, "Ghee was never a very big part of my diet. I’ve always been more conscious because cholesterol issues run in my family. Whether it was non-vegetarian food or anything else, it was always on my mind, I didn’t want to go overboard.

"We start building habits early. You can't keep feeding children excessive amounts of certain foods and then expect them to suddenly not be overweight and head to the gym later in life. It has to make sense."

The 38-year-old mother-of-two soon clarified that she considers ghee to be a problem when consumed in excess. D'Souza, who follows a strict plant-based lifestyle, explained that ghee, a known superfood, stays far away from her diet and instead she prefers to consume sesame seeds (til) for similar benefits.

She also addressed questions about giving up ghee and butter, stating, "I enjoyed a little bit of ghee and butter, but only in tiny portions. So when I eventually gave it up, it wasn’t a big deal," while acknowledging the sensory appeal of ghee, "I know it’s very tasty and it smells amazing."

Is Ghee Indeed Bad For You?

Made from cow milk butter, ghee contains about 130 calories and 15 grams of fat on average. It is also known to be rich in Vitamin A, D, K and E as well antioxidants.

However due to its high saturated fat content, some experts claim ghee can raise bad cholesterol levels in some people. While saturated fats help control high cholesterol and promote good heart health only apply when it is consumed in moderation. Ghee consumed in excess is indeed unhealthy.

However, it also contains beneficial fats (like omega-3s & CLA) and fat-soluble vitamins, offering potential anti-inflammatory benefits in small amounts, making it a balanced choice for many when balanced with overall diet and lifestyle.

A 1999 Indian Journal of Dairy & Biosciences study also noted that when researchers studied Indian men in a rural population who ate high amounts of ghee, they showed a significantly lower prevalence of coronary heart disease.

High doses of medicated ghee decreased serum cholesterol, triglycerides, phospholipids, and cholesterol levels in those suffering from psoriasis, a chronic autoimmune skin condition causing rapid skin cell buildup, leading to red, scaly, itchy patches, often on scalp, elbows, knees and back.

Who Should Avoid Ghee?

Experts recommend those suffering from conditions such as heart, digestive and kidney issues as well as obesity to steer clear from the superfood. Cholesterol patients should also avoid ghee as it is rich in fatty acids that may increase blood pressure and increase the risk of heart disease.

Lastly, those suffering from jaundice should also avoid it as it can cause major problems for the liver. Doctors suggest consuming not more than two teaspoons of ghee every day as it may pose certain health risks.

Researchers at Stanford University have developed a new AI model which can predict more than 100 health conditions including cancer, mental health, cardiovascular issues and death using sleep study data.

SleepFM uses polysomnography, a comprehensive sleep assessment that utilizes various sensors to record brain activity, heart activity, respiratory signals, leg movements, eye movements and more to provide an accurate prediction of future disease risk, according to the study published in Nature on January 6.

Emmanuel Mignot, Craig Reynolds Professor in Sleep Medicine and co-senior author of the study, said, "We record an amazing number of signals when we study sleep. It’s a kind of general physiology that we study for eight hours in a subject who’s completely captive. It’s very data rich."

It remains unclear when SleepFM will be commercially available to the public and whether it will be incorporated into wearable technology such as watches and phones.

How Does It Work?

The AI model has been trained on nearly 600,000 hours of sleep data collected from 65,000 participants which had been split into five-second increments to combine multiple body signals, such as brain activity, heart activity, muscle activity, pulse and breathing and understand how they relate to each other.

James Zou, PhD, associate professor of biomedical data science and co-senior author of the study commented, "One of the technical advances that we made in this work is to figure out how to harmonize all these different data modalities so they can come together to learn the same language."

After being trained to identify and link different body signals, SleepFM was taught how to understand standard sleep analysis tasks such as different stages of sleep and diagnosing the severity of sleep apnea, a serious sleep disorder where breathing repeatedly stops and starts often due to airway blockage or the brain failing to signal muscles.

Once the model was seen successfully identifying sleep-related issues, it was paired with the sleep recordings and health data of 35,000 patients collected over 25 years for it to learn how to identify chronic diseases through nighttime body signals.

Which Diseases Can It Accurately Predict?

Particularly, SleepFM excelled at predicting Parkinson’s disease, dementia, hypertensive heart disease, heart attack, prostate cancer, breast cancer and death.

“We were pleasantly surprised that for a pretty diverse set of conditions, the model is able to make informative predictions,” Zou said.

Even though heart signals were prominently used to predict heart disease and brain signals were predominant in mental health predictions, the researchers noted that it was the combination of all the data modalities that achieved the most accurate predictions.

“The most information we got for predicting disease was by contrasting the different channels. Body constituents that were out of sync. A brain that looks asleep but a heart that looks awake, for example, seemed to spell trouble,” Mignot said.

Zhou added, "From an AI perspective, sleep is relatively understudied. There’s a lot of other AI work that’s looking at pathology or cardiology, but relatively little looking at sleep, despite sleep being such an important part of life.

"SleepFM is essentially learning the language of sleep."
