Healthy Living

Actinomycetes are a group of Gram-positive bacteria that occupy an intermediate position between bacteria and fungi. They form branched filamentous structures resembling mold mycelium and are capable of producing spores. While many species of actinomycetes are found in nature and play a role in the decomposition of organic matter, some strains can be pathogenic and pose a health risk when they begin to proliferate in the indoor environment.

Bifidobacteria are one of the key representatives of the normal gut microbiota, playing an important role in maintaining overall health. They colonize the intestines from the first days of life and participate in numerous processes that support digestion, strengthen the immune system, and synthesize essential vitamins.

However, with age and under the influence of various factors, their numbers decrease, leading to microbial imbalance and increasing the risk of various diseases. Understanding the distribution of bifidobacteria in the gut, their functions, and the factors that affect their levels helps maintain microbiome balance and prevent potential health problems.

Microbiome refers to the collection of microorganisms that inhabit not only the gut, but also the skin, respiratory tract, mucous membranes, urogenital system, and even the surrounding environment. The human body contains more microbial cells than human cells: for every human cell, there are about 1.3 microbial cells. The total mass of the microbiome is 1.5–2 kg, and its genes outnumber human genes by a factor of 150.

Food colorings are additives used to give, enhance, or restore the color of food and beverages. They can be either synthetic (artificial) or natural, derived from plants, minerals, or animals.

Manufacturers use colorings to make products more appealing, as bright colors are associated with freshness and quality. They also help compensate for the loss of natural color that occurs during processing, freezing, and storage. Additionally, certain shades create a recognizable image for the product — for example, oranges are dyed to match consumer expectations.

Sugar substitutes are substances used instead of sugar to provide a sweet taste in food and beverages. Their popularity stems from the desire to reduce calorie intake. Artificial and natural sweeteners allow people to enjoy sweetness without extra calories, which is especially appealing to those managing their weight, following a diet, or monitoring their body’s energy balance.

In addition, sugar substitutes help regulate blood glucose levels. People with diabetes often use them to avoid sharp spikes in blood sugar caused by regular sucrose. Some sweeteners have minimal impact on insulin response, making them a convenient alternative for controlling metabolic processes.

Globalization has changed the world, promising to improve people’s lives and benefit all countries. The idea was that each nation would focus on its greatest potential. For example, the U.S. would develop technology, Canada would extract resources, and China would provide labor. Free trade allowed companies to sell goods worldwide without restrictions, and large corporations found ways to move production to countries with cheap labor. This significantly reduced costs and increased profits. Mass production made goods cheaper, flooding markets with inexpensive products — including food.

Traveling is a wonderful opportunity to gain new life experiences, but it can also pose health risks. When in enclosed spaces such as airplanes, or in crowded places like airports, travelers are more likely to encounter infections that spread from person to person.

The events of recent years, associated with the coronavirus pandemic, have shown how quickly diseases can spread around the world. But viruses are only part of the problem. During travel, one may also encounter bacterial infections, which can be just as dangerous. That’s why it is important not only to understand how infections are transmitted, but also to know how to protect yourself.

The art of tattooing, once associated with subcultures and informal groups, has now firmly entered the daily lives of millions of people. Body artwork has become a vibrant expression of individuality, and social media has turned tattoos into a real trend. However, despite their aesthetic appeal, tattoos carry certain health risks. Heavy metals contained in tattoo inks can accumulate in the body and cause allergic reactions, while non-compliance with sanitary norms during the application of tattoos increases the risk of infectious diseases. Additionally, the long-term effects on the immune and lymphatic systems are still not fully understood.

Vitamin B12, also known as cobalamin, is a crucial water-soluble vitamin that plays a key role in maintaining nervous system health, red blood cell formation, and DNA synthesis. It is essential for normal brain and nerve function, as well as for energy production in the body. Vitamin B12 is naturally found in animal products such as meat, fish, dairy, and eggs. Adequate intake is vital for normal bodily function, as a deficiency can lead to serious health issues.

In the first part, we discussed the issue of pathogenic biofilms forming on moisture-exposed surfaces in the home: Biofilms in the Home and Their Impact on Human Health. Now we will explore what can be done to reduce this impact on our health, as regular cleaning is only a part of the necessary measures.

In modern homes and apartments, despite visible cleanliness, various microbes, fungi, and bacteria can accumulate, many of which pose serious health risks. Sources of microbial contamination are diverse: they can include human waste products, pets, particles of soil and dust brought in from outside, as well as water and air coming from external sources. Often, microbial contamination goes unnoticed, increasing the risk of developing various diseases.
