But now we know that not all fat is the same. By understanding the difference between good and bad fats and how to include more healthy fat in your diet, you can improve your mood, boost your energy and well-being, and even lose weight. Since fat is an important part of a healthy diet, rather than adopting a low-fat diet, it’s more important to focus on eating more beneficial “good” fats and limiting harmful “bad” fats. What is their experience with the health risks associated with ‘bad fat’ intake for example obesity, diabetes, heart disease, strokes, cancer, etc.? Why is eating healthy so important? What are are recommendations for maintaining a healthy diet of ‘good fats’? What's the deal with fats?arrow_forwardWrite about the background information of plant-based meat in around 300 wordsarrow_forward
- DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. It contains the biological instructions that make each species unique. DNA, along with the instructions it contains, is passed from adult organisms to their offspring during reproduction. Nearly every cell in a person's body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA). The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people. The order, or sequence, of these bases determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences. DNA bases…arrow_forwardIn order to be healthy, humans must consume a variety of amino acids. Any animal product, such as eggs, milk, and meat, contains all of these amino acids.

Complete solution is required. “The coronavirus disease (COVID-19) is an infectious disease caused by a new strain of coronavirus. This new virus and disease were unknown before the outbreak began in Wuhan, China, in December 2019. On 30 January 2020, the Philippine Department of Health reported the first case of COVID-19 in the country with a 38-year-old female Chinese national. On 7 March, the first local transmission of COVID-19 was confirmed. WHO is working closely with the Department of Health in responding to the COVID-19 outbreak.” Aki and her family were alarmed with the news they watched and so first thing in the morning they rush to the nearest convenient store to secure disinfectant and sanitizers but unfortunately the store already had empty shelves of the essentials they needed.
