essay on nutrition in living organisms
Answers
Nutrition is the essential organic nutrients living organisms require for growth, maintenance, reproduction and repair. This is an essential process for the organism’s survival. Living organisms require energy to survive; this energy is derived from nutrients, or food. Ingestion, digestion, absorption and excretion are the stages of processing food. Heterotrophs are organisms which cannot synthesise their own food and are therefore totally reliant on organic substances for nutrition. Animals are heterotrophs and are divided into three categories; herbivores, carnivores and omnivores depending on how they obtain their food. Herbivores: eat mainly plant material, seeds or fruit. (Gordon McL Dryden, 2008). Omnivores: eat both vegetableNutrition and Mental HealthHealth is the state of fitness of the body and mind. Health is usually determined by individual's lifestyle. A healthy lifestyle keeps one's mind and body in good shape and similarly a bad lifestyle leads us to a very bad shape. Food and nutrition play major roles in everyone's life. If someone does not get the right amount of nutrition, their mind and body won't function right. The body would not produce enough energy. (Markey, 2004) Eating habits should be good because if we do not eat the right foods our mind and body will be weak and tired. Bad eating habits leave the person with not enough energy to do any mental or physical activity properly.Mental health brings the equilibrium between all aspects of our life - physical, social, emotional and spiritual. It effects on how we manage surroundings and make all sorts of choices in our lives - undoubtedly it is an important part of our overall health. (Gold, 2003)Mental health is when your mind is set on things like drugs and losing weight and other things like that. If you have your mind set on losing weight, you will be more tempted to try diets and other things that aren't good for your body. If you are depressed you will be more likely to try drugs.Recently, depression rates have been soaring. More people are succumbing to all the anti-depression medication commercials and accepting that they are depressed. Ironically, alongside of depression, obesity rates are also dramatically rising. What does this mean? Depression and obesity are two devils working hand in hand to make people unhealthy. In many cases, humans may eat to suppress their hunger; in turn, humans may become depression due to the appearance of their body. (Stuart, 2002) This creates a dangerous chain of bodily abuse, which commonly ends in death. One's mental and emotional health is determined by the way the person in question reacts and possibly adapts to the world around them. We may know a person who for some reason is able to keep their head up and maintain a smile throughout their day even though they are enduring horrifyingly bad situations. This is because they are interpreting their world in a way different than another might be. Many people need to realize this in order to become healthy. A healthy person is in control of his or her thoughts, feelings, and behaviors. They feel good about themselves and have good relations with other people. Some people are overwhelmed by stress due to their complicated and seemingly depressing lives that are filled with only short...

Importance of a Balanced Diet
Most people believe that a balanced diet is definitely the key to a healthy lifestyle. It is rightly believed as even scientists say so. When we always consume a balanced diet, we will maintain our physical as well as mental health. A balanced diet must contain the proper foods that are consumed in apt quantities. A perfect balanced diet is composed of carbohydrates, proteins, fats, minerals, high fiber content, vitamins, and more.
Moreover, nowadays the trend of junk food is here to stay. People are not taking a balanced diet rather eating all sorts of harmful foods. It is more important than ever to tell people about the importance of a balanced diet. You cannot merely exercise and expect your body to stay fit. A balanced diet is crucial for that.
Most importantly, it is called a ‘balanced’ diet because it requires all the foods to be eaten in a balanced manner. For instance, if you intake large amounts of carbohydrates and a little amount of protein, then that will not be called a balanced diet, even if you are eating the right foods. The balance needs to be maintained for that.
