health and its basics: nutrition exercise and more
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.
