 This is SARS CoV-2. It belongs to the family of coronaviruses, named for crownlike spikes on their surfaces. SARS CoV-2 can cause COVID-19, a contagious viral infection that attacks primarily your throat and lungs. What actually happens in your body when you contract the coronavirus? What exactly causes your body to develop pneumonia? And how would a vaccine work? The coronavirus must infect living cells in order to reproduce. Let's have a closer look. Inside the virus, genetic material contains the information to make more copies of itself. A protein shell provides a hard protective enclosure for the genetic material as the virus travels between the people it infects. An outer envelope allows the virus to infect cells by merging with the cell's outer membrane. Projecting from the envelope are spikes of protein molecules. Both a typical influenza virus and the new coronavirus use their spikes like a key to get inside a cell in your body, where it takes over its internal machin...

 Water is virtually everywhere, from soil moisture and ice caps, to the cells inside our own bodies. Depending on factors like location, fat index, age, and sex, the average human is between 55-60% water. At birth, human babies are even wetter. Being 75% water, they are swimmingly similar to fish. But their water composition drops to 65% by their first birthday. So what role does water play in our bodies, and how much do we actually need to drink to stay healthy? The H20 in our bodies works to cushion and lubricate joints, regulate temperature, and to nourish the brain and spinal cord. Water isn't only in our blood. An adult's brain and heart are almost three quarters water. That's roughly equivalent to the amount of moisture in a banana. Lungs are more similar to an apple at 83%. And even seemingly dry human bones are 31% water. If we are essentially made of water, and surrounded by water, why do we still need to drink so much? Well, each day we lose two to three liters th...

  A, C, E, D, B, K. No, this isn't some random, out of order alphabet. These are vitamins, and just like letters build words, they're the building blocks that keep the body running. Vitamins are organic compounds we need to ingest in small amounts to keep functioning. They're the body's builders, defenders and maintenance workers, helping it to build muscle and bone, make use of nutrients, capture and use energy and heal wounds. If you need convincing about vitamin value, just consider the plight of olden day sailors, who had no access to vitamin-rich fresh produce. They got scurvy. But vitamin C, abundant in fruits and vegetables, was the simple antidote to this disease. While bacteria, fungi and plants produce their own vitamins, our bodies can't, so we have to get them from other sources. So how does the body get vitamins from out there into here? That's dependent on the form these compounds take. Vitamins come in two types: lipid-soluble and water-soluble, a...

 We hear about calories all the time. How many calories are in this cookie? How many are burned by 100 jumping jacks, or long distance running, or fidgeting? But what is a calorie, really, and how many of them do we actually need? Calories are a way of keeping track of the body's energy budget. A healthy balance occurs when we put in about as much energy as we lose. If we consistently put more energy into our bodies than we burn, the excess will gradually be stored as fat in our cells, and we'll gain weight. If we burn off more energy than we replenish, we'll lose weight. So we have to be able to measure the energy we consume and use, and we do so with a unit called the calorie. One calorie, the kind we measure in food, also called a large calorie, is defined as the amount of energy it would take to raise the temperature of one kilogram of water by one degree Celsius. Everything we consume has a calorie count, a measure of how much energy the item stores in its chemical bon...

 From the minute we're born, we're aging. Constant exposure to our environment, the things we eat, and stresses from both inside and outside our bodies all cause us to age over time. Aging is highly complex, but scientists are starting to understand what happens at the cellular and molecular levels. For example, healthy cells are damaged over time when our immune systems shift from reacting to short-term problems like injuries and infections, to gradually producing chronic inflammation throughout the body. Time also gradually shortens the telomeres that act as protective caps for our DNA-containing chromosomes. These and other changes make our bodies less and less able to deal with stress from inside and outside of our body, so when damage reaches a critical level, our cells, tissues, and organs may no longer perform normally and our health starts to decline. The changes associated with aging start to happen on some level at day one. We begin to experience their effects early i...

  it would if you ate another tortilla or a slice of bread. Or, you can also choose water with a squeeze of lemon or lime. How you create your plate is up to you, you have many options, as long as you remember to follow these healthy guidelines, and tara, you're all set! You might be thinking how can you use the plate method to make vegetable beef soup or other meals? Simply follow the same idea. Fill your pot with low sodium broth and lots of healthy vegetables like corn, cabbage, zucchini, carrots, and onions and some lean beef, but not too much. Just like you'd put on a quarter of your plate for each person you're serving. If you want, add your favorite type of bread on the side, and you've got the right amount for a healthy meal. Mm-hmm, enjoy!

 Which of these has the least carbohydrates? This roll of bread? This bowl of rice? Or this can of soda? It's a trick question. Although they may differ in fats, vitamins, and other nutritional content, when it comes to carbs, they're pretty much the same. So what exactly does that mean for your diet? First of all, carbohydrate is the nutritional category for sugars and molecules that your body breaks down to make sugars. Carbohydrates can be simple or complex depending on their structure. This is a simple sugar, or monosaccharide. Glucose, fructose, and galactose are all simple sugars. Link two of them together, and you've got a disaccharide, lactose, maltose, or sucrose. Complex carbohydrates, on the other hand, have three or more simple sugars strung together. Complex carbohydrates with three to ten linked sugars are oligosaccharides. Those with more than ten are polysaccharides. During digestion, your body breaks down those complex carbohydrates into their monosaccharid...

  health it's the state of complete physical mental and social well-being not just the absence of disease or infirmity and good health is something we strive to achieve not just individually but also as a community but if we look around us our family friends and others we know that health is very variable for example in 2016 the life expectancy of a child born in Sierra Leone was 53 years while in Australia it was 83 years but even within Australia the life expectancy of indigenous people is about 10 years lower than that of non-indigenous people and even within a specific group of people health can change based on a person's income level of education or occupation so why is health so variable to answer that question we must understand the factors that influence health the factors that influence a person's health are called determinants of health these include who they are such as age sex and genetic makeup and what they do as in health behaviors such as smoking physical ac...
