HEALTH(Foundation of IT)

INTRODUCTION

we all know that we require food because the body needs energy and more.

A healthy food is a plant or animal product that provides essential nutrients and energy to sustain growth, health and life while satiating hunger.

Eating right not only helps you feel and look good, but it also provides energy to carry you through any challenging race, training or work day.

Health is a dynamic process because it is always changing. We all have times of good health, times of sickness, and maybe even times of serious illness. As our lifestyles change, so does our level of health.

Those of us who participate in regular physical activity do so partly to improve the current and future level of our health. We strive toward an optimal state of well-being. As our lifestyle improves, our health also improves and we experience less disease and sickness. When most people are asked what it means to be healthy, they normally respond with the four components of fitness mentioned earlier (cardiorespiratory ability, muscular ability, flexibility, and body composition). Although these components are a critical part of being healthy, they are not the only contributing factors. Physical health is only one aspect of our overall health.

WHAT IS IMPORTANCE OF HEALTH?

Eating healthy foods and exercising regularly are challenges for almost everyone. It's tough to find the time and motivation to devote to a healthy diet and workout routine, and to balance those factors with other activities. However, the mental and physical benefits of following a healthy lifestyle are significant, and the bottom line is that consistently healthy choices lead to a longer life.

HEALTHY DIET Diet is very important in maintaining a healthy

lifestyle. he importance of diet can't be overstated for a healthy lifestyle. People get the vitamins, minerals and nutrients they need to function and thrive from the foods they eat, so choosing foods that offer the most of those components helps improve quality of life. According to the Food Standards Agency, a healthy diet for most people consists of fresh fruits and vegetables, whole grain foods, lean proteins and some low fat or nonfat dairy products. It's just as important to limit foods that are high in fat, sugar, sodium and cholesterol as it is to choose healthy foods.

EXERCISE

There are just as many, if not more, benefits to exercising regularly than there are to following a healthy diet. At its most basic level, exercise burns calories. The Centers for Disease Control and Prevention notes that exercise and diet play dual roles in maintaining healthy weight and aiding weight loss. The muscles in people's bodies work best when they are used regularly, built up and strengthened through activity. In addition, people's hearts grow stronger and healthier when they engage in cardiovascular exercise that raises heart rates for an extended time.

PHYSICAL BENEFITS

people who exercise regularly have lower occurrences of high blood pressure, high cholesterol, osteoporosis, type 2 diabetes and cancer. They also have higher energy levels and sleep better. The Cleveland Clinic suggests that a healthy, nutrient- and antioxidant-rich diet also guards against cancer and helps improve the immune system's functions. Finally, the CDC notes that people of all ages, ethnicities, sizes and shapes have the power to extend the length of their lives by regularly engaging in physical activity.

MENTAL BENEFITS

Eating well and getting proper exercise offer mental benefits as well as better physical health. HelpGuide.org notes that healthy, mindful eating practices can help reduce stress in adults' lives, as can mild physical activities, such as walking, yoga. Exercise stimulates brain chemicals that make people happy. Also, the healthy lifestyle helps sharpen thinking, learning and judgment skills, and reduces the risk of depression.

EATING: What you eat and how you feel, both mentally and

physically, have a close connection. Following a balanced, nutritious diet isn’t always easy, cheap or convenient, but it has a significant positive impact on both your short- and long-term health. Eating poorly, in contrast, can tank your energy levels, increase your risk of disease and take years off your life.

At least 2.7 million people around the world die each year as a result of not getting enough fruits and vegetables in their diets, according to the World Health Organization. Eating a healthy diet instead of an unhealthy diet can help you get all the essential nutrients you need and limit your risk for a number of health conditions.

FOOD AND MENTAL HEALTH:

Making smart food choices boosts your mental health and your physical health. Balanced diets are associated with lower incidences of depression, anxiety and bipolar disorder, and there is also a link between good mental health and eating whole, unprocessed foods. What you eat also affects how easily you can relax at night and get high-quality sleep. According to nutritional therapist Jo Lewin, large meals and sugary, fatty foods tax your body’s digestive system in a way that makes it difficult for you to drift off and sleep well.

HEALTHY VS. UNHEALTHY DIETS Healthy diets are made up mainly of nutrient-rich

foods, such as legumes, fruits and vegetables, whole grains, low-fat dairy products, lean protein and nuts and seeds. Unhealthy diets are high in fat, saturated fat, trans fat, sodium and added sugars. These diets often contain a lot of processed or fast foods that are high in calories but don't contain many nutrients. People following a healthy diet watch their portion sizes so they maintain a healthy weight, since both the quantity and the quality of the food you eat is important for a healthy diet.

Eating well is crucial for growing teenagers because their nutrient needs are higher during this time. Most teenagers do not meet the recommendations for whole grains and fruit and vegetable intake. Healthy eating can be difficult for teens because they are often spending time eating with friends, eating fast food and snacking on energy-dense foods and beverages. This eating pattern can lead to an excessive intake of calories, mostly from unhealthy fat and sugar, which increases the risk for obesity.

DISEASE RISK Up to 40 percent of cancers may be due, in part, to

following an unhealthy diet. Unhealthy diets also increase your risk for Type 2 diabetes, obesity and heart disease. The World Health Organization estimates that approximately 2.6 million deaths each year are due to obesity-related illnesses.

No matter what your age, your daily food choices can make a huge difference in your overall health and in how you feel and look. Eating a healthy, balanced diet daily provides the nutrients your body needs to keep your bones, organs and muscles in optimum shape. These nutrients include fats, carbohydrates, protein, vitamins and minerals. Healthy eating may also help you maintain a healthy weight, boost your heart health, prevent diabetes and improve your brain function.

EXERCISE: You already know the physical benefits of exercise:

better health, reduced risk of potentially serious disease, lower blood pressure and a well-toned body. Exercise carries emotional and social benefits as well. People that exercise regularly are more likely to classify themselves as happy than those that don't. Reap all of the benefits of exercise by getting in 30 to 60 minutes daily.

SOME BENEFITS OF EXERCISING:

• Reduced risk of death• More energy, less fatigue• Improved mood• Improved bone density• Less joint pain• Weight control

SOME RISKS OF NOT EXERCISING INCLUDE:

• Risk of secondary cancers• Anxiety and depression• Obesity• Recurrence

BALANCED DIET:

A well-balanced diet provides the right vitamins, minerals and nutrients to keep the body and mind strong and healthy. Eating well can also aid in the prevention of a variety of diseases and health problems, as well as helping to maintain a healthy body weight, providing energy and promoting a general feeling of well-being.

IMMUNE SYSTEM

A balanced diet is very important to the immune system, helping to ensure that the vitamins, minerals, and other nutrients necessary to its efficient function are available. Even minimal deficiencies in certain nutrients can impair immune system function, such as vitamin A, B-vitamins, vitamin C, vitamin .E, Zinc, iron and selenium.

ENERGY:

One of the most noticeable benefits of a balanced diet is energy. Keeping your body fueled with the right proportions of vitamins, minerals and nutrients can give you the energy you need to make the most of your day. Healthy carbohydrates, such as whole grains, fruits, vegetable and legumes are slow to digest, keeping blood sugar and insulin levels on an even keel for a steady supply of energy throughout the day. Healthy proteins are also vital for energy levels, and can be added to the diet by eating lean meats, poultry and fish, as well as whole grains, tofu, beans and nuts.
