Dear MEL Topic Readers, 

Ultraprocessed foods make up to 70% of the US food supply. How to reduce your intake

Do you know what UPFs are or have any idea how much ultra-processed foods (UPFs) you eat daily? In general, foods that are processed highly and contain ingredients that aren’t normally found in the kitchen, such as certain individual nutrients, flavor enhancers, colors, additives, and stabilizers are considered UPFs. They tend to contain some ingredients excessively, such as sugar, salt, fat, and carbohydrates. They are tasty and convenient but are also calorie-dense. A study found that those who eat UPFs mainly for their diet take 500 more calories daily than those who don’t. Although fat, sugar, sodium, and starchy carbohydrates aren’t usually found together in nature, ultra-processed foods often contain these magic ingredients together to entice your taste buds. So, if you regularly eat ultra-processed foods, such as breakfast cereals, margarine, chips, packaged cakes and biscuits, sweet chocolate, and prepared foods, you get more calories, fat, sugar, and salt than you recognize. Since such highly processed foods are linked to illnesses, such as obesity, diabetes, cardiovascular disease, cancer, depression, cognitive decline, and stroke, you may want to be aware of which foods are highly processed and how to avoid them.

Myanmar villagers reveal 'desperate' illegal kidney sales

An organ transplant is a surgical procedure that replaces a damaged organ with a healthy organ from a donor. Organs that have been successfully transplanted include the heart, kidneys, liver, lungs, pancreas, intestine, thymus and uterus. Organ donors may be living, brain dead, or dead via circulatory death. Although the demand for organ transplants has been increasing, the supply meets only about 10% of the needs, according to the World Health Organization (WHO). So where there is unfilled demand, smuggling would emerge. The kidneys are a pair of fist-sized organs located near the middle of the back on either side of the spine, which perform many vital functions, including filtering blood, regulating blood pressure, and producing hormones. Although most people who live with just one of their kidneys can live normal lives, there are health risks such as developing high blood pressure, protein in the urine, chronic kidney diseases, and damage to other organs. Buying or selling human organs is illegal in both Myanmar and India, and documents are needed to perform an organ transplant. However, agents find potential donors who are desperate to make money by any means, forge documents, and arrange for a doctor and hospital to perform a transplant. The problem is that the donors are often not advised of risks to their health and legal liabilities. The scientific fiction “Never Let Me Go” by Kazuo Ishiguro is an extreme version of such organ transplantations and donors.

Dear MEL Topic Readers, 

These cities have big rat problems, and there’s one thing to blame

While we don’t know how many, most of us live with more rats than we imagine. They find shelter in various urban spaces like sewers, abandoned buildings, cracks in walls, under sidewalks, and within dense vegetation and eat discarded food scraps from humans, accessing them through trash cans, dumpsters, and food spills on the ground, which are often abundant in urban environments. Though rats live only for a few years, they are very fertile. Females can become pregnant when they are only a few months old and can produce six to 12 offspring up to a dozen times a year. If they live in a warm environment where food is plenty like in cities, the number of rats could increase easily. According to the data collected from 13 US cities, Toronto, Tokyo, and Amsterdam, the number of sightings and trappings has increased over the last 12 years or so. As warmer climates and environments could help rats grow and reproduce for a longer time, we may be bothered by more rats in the future, which is a problem as they gnaw and damage wires and cables and transmit diseases like leptospirosis, hantavirus, and plague to humans. Another impact of global warming and urbanization.

Dear MEL Topic Readers, 

Is it time to change how we buy travel souvenirs?

What are souvenirs? Some of the most popular souvenirs are magnets or mug cups with a logo or image of the place. Also, shawls made of local fabric and artworks handcrafted by Indigenous peoples are in high demand. But where are they actually produced and by who? It was found that as much as 75% of souvenirs marketed as "Indigenous" in Australia were counterfeit and over 70% of Thailand’s elephant pants were made overseas. Also, most fabrics sold as pashmina, cashmere wool of a special kind, in a Kashmir market in India are not genuine. As many people travel to distant places, most souvenirs are now just locally sold affordable and portable commodities that were mass-produced somewhere else. While traveling, extraordinary experiences, including food, scenery, atmosphere, people, activities, and even difficulties are often more memorable than materials, most travelers still buy souvenirs to remember the trip or share the event with someone. In the end, the money that travelers spend helps the local economy in some way or other.

Dear MEL Topic Readers, 

What do countries call themselves? The stories behind their original names

A little over 8.2 billion people live in 200 or so states in the world. English and Chinese are the only languages that are spoken by more than one billion people while as many as 7,000 other languages are spoken across the world. However, most countries are called by English names, such as Japan, China, and India even though they are locally called Nihon or Nippon, Zhongguo, and Bharat respectively in their languages. In Africa, many names of the 54 countries are rooted in colonial history or European or Arabian traders. But locally, South Africa is called Mzans and Egypt calls itself Masr in Arabic. In Europe, Germany is called Deutschland, Spain is Espana, and Finland is Suomi in their languages. In 2021, Turkey changed its identification to Turkiye to better represent its culture, civilization, and values of the nation, and also to avoid being confused with the bird turkey. Will there be a rename movement to reflect historical and cultural identities?

Dear MEL Topic Readers, 

How much protein do you really need to get strong?

Protein has many functions in the body. For example, eating enough protein helps maintain muscle mass and grow muscle when you exercise. Also, protein helps the body build and repair tissues, which is especially important after an injury. In addition, it supports the immune system, helps maintain bone health, and boosts metabolism. Interestingly, it helps with weight control as well since the body burns more calories digesting protein than carbohydrates. Then how much protein should we take each day? It is recommended that an adult should take about 0.8 grams of protein per kilogram of body weight. So if you weigh 70 kg, you should take 56 grams of protein a day. But if you are very active or exercise a lot, you’ll need 1 gram of protein per kg each day. Also, older people need to take more protein as they tend to lose more muscle mass than when they were younger. To take sufficient protein, you don’t have to eat a lot of red meat or eggs every day as there are many different kinds of protein-rich foods like soybeans, lentils, nuts, and yogurt. You can also take protein supplements to help increase protein intake, but only to supplement your diet. The best way to achieve a healthy diet is to plan meals with protein-rich food and try to eat protein at every meal.

Dear MEL Topic Readers, 

World's glaciers melting faster than ever recorded

A glacier is a mass of ice that is constantly moving downhill. The estimated volume of glaciers, not including the ice sheets of Antarctica and Greenland is around 170,000 km3. Glaciers’ ice is the largest freshwater reservoir, accounting for nearly 70% of the world’s freshwater. Hundreds of millions of people are relying on seasonal meltwater from glaciers to some extent. However, glaciers melt faster as the climate warms. Global sea levels have risen about 20 centimeters on average since 1900, and the rate of increase has been accelerating in recent decades, nearly 30% of which is estimated to have been contributed by melting glaciers. If all the 200,000 or so glaciers melted, we would lose the precious freshwater reservoirs while facing accelerated sea level rise. Also, if that happened, ice sheets in polar regions would have melted. Combined, the global sea level would rise by approximately 70 meters. Recent studies found that glaciers outside the polar regions have lost 270 billion tonnes of ice a year between 2000 and 2023, enough mass to supply three liters of fresh water to everyone on Earth every day. And they are melting faster and faster.
