Aspects of Lifestyle

In addition to nutrition, health is affected by genetics, the environment, life cycle, and lifestyle. One facet of lifestyle is your dietary habits. Dietary habits include what a person eats, how much a person eats during a meal, how frequently meals are consumed, and how often a person eats out.

Other aspects of lifestyle include physical activity level, recreational drug use, and sleeping patterns, all of which play a role in health and impact nutrition. Following a healthy lifestyle improves your overall health.

Physical Activity

Canada has set Physical Activity Guidelines, which are available at the website of The Canadian Society for Exercise Physiology.

The Canadian Physical Activity Guidelines are broken into the following age categories; Early Years: 0-4, Children + Youth: 5-17, Adults: 18-64 and Older Adults: 65+. Guidelines do not differ between genders, sex, race or ethnicity and there are no limitations to the ways that individuals can reach the recommend levels of activity. By abiding by these guidelines you will reduce your risk of premature death, cardiovascular disease, stroke, hypertension, colon cancer, breast cancer, type 2 diabetes and osteoporosis. It can also lead to improved fitness, strength and mental health. [1]

Recommendation For Adults (18-64yrs)[2]

  • At least 150 minutes of moderate to vigorous intensity aerobic physical activity per week in bouts of 10 minutes or more.
  • Additionally it is beneficial to add muscle and bone strengthening activities using major muscle groups at least 2 days per week
  • More physical activity provides greater health benefits

Moderate intensity activity causes a little sweat and harder breathing. Examples include brisk walking and bike riding.

Vigorous intensity activity causes you to sweat and lose your breath. Examples include jogging and cross-country skiing.

To reach your 150 minutes, you could: 

  • join a running group
  • go for a brisk walk
  • join an exercise class
  • bike or walk to work or the grocery store
  • perform household chores such as raking, vacuuming, and cleaning
  • join a sports team

Recreational Drug Use

Recreational drug use, which includes tobacco-smoking, electronic smoking device use, and alcohol consumption along with narcotic and other illegal drug use, has a large impact on health. Smoking cigarettes is the leading cause of lung cancer and is directly linked to eleven other types of cancer, heart disease, and several other disorders or diseases that markedly decrease quality of life and increase mortality. In the United States, smoking causes more than four hundred thousand deaths every single year, which is far more than deaths associated with any other lifestyle component. [3]

Also, according to the Centers for Disease Control and Prevention (CDC), excessive alcohol intake causes an estimated seventy-five thousand deaths per year. [4] Staying away from excessive alcohol intake lowers blood pressure, the risk of injury, heart disease, stroke, liver problems, and some types of cancer. While excessive alcohol consumption can be linked to poor health, consuming alcohol in moderation has been found to promote health such as reducing the risk for heart disease and Type 2 diabetes in some people. The United States Department of Health and Human Services (HHS) defines drinking in moderation as no more than one drink a day for women and two drinks a day for men. [5] To reduce your harm from drinking, the Canadian Centre on Substance and Addition latest guidelines recommend that females consume no more than 10 drinks a week with no more than 2 drinks on most days and that males consume no more than 15 drinks a week with no more than 3 drinks on most days.

llicit and prescription drug abuse are associated with decreased health and is a prominent problem in the United States and Canada. The health effects of drug abuse can be far-reaching, including the increased risk of stroke, heart disease, cancer, lung disease, and liver disease. [6]

Sleeping Patterns

Inadequate amounts of sleep, or not sleeping well, can also have remarkable effects on a person’s health. In fact, sleeping can affect your health just as much as your diet. Scientific studies have shown that insufficient sleep increases the risk for heart disease, Type 2 diabetes, obesity, and depression. Abnormal breathing during sleep, a condition called sleep apnea, is also linked to an increased risk for chronic disease. [7]

Personal Choice: The Challenge of Choosing Foods

There are other factors besides environment and lifestyle that influence the foods you choose to eat. Different foods affect energy level, mood, how much is eaten, how long before you eat again, and if cravings are satisfied. We have talked about some of the physical effects of food on your body, but there are other effects too.

Food regulates your appetite and how you feel. Multiple studies have demonstrated that some high fiber foods and high-protein foods decrease appetite by slowing the digestive process and prolonging the feeling of being full or satiety.

The effects of individual foods and nutrients on mood are not backed by consistent scientific evidence, but in general, most studies support that healthier diets are associated with a decrease in depression and improved well-being. To date, science has not been able to track the exact path in the brain that occurs in response to eating a particular food, but it is quite clear that foods, in general, stimulate emotional responses in people. Food also has psychological, cultural, and religious significance, so your personal choices of food affect your mind, as well as your body.

The social implications of food have a great deal to do with what people eat, as well as how and when. Special events in individual lives—from birthdays to funerals—are commemorated with equally special foods. National food traditions are carried to other countries when people immigrate. Being aware of these forces can help people make healthier food choices—and still honor the traditions and ties they hold dear.

Factors That Drive Food Choices

Along with these influences, a number of other factors affect the dietary choices individuals make, including the following:

  • taste, texture, and appearance: Individuals have a wide range of tastes which influence their food choices, leading some to dislike milk and others to hate raw vegetables. Some foods that are very healthy, such as tofu, may be unappealing at first to many people. However, creative cooks can adapt healthy foods to meet most people’s taste.
  • economics. Access to fresh fruits and vegetables may be scant, particularly for those who live in economically disadvantaged or remote areas, where cheaper food options are limited to convenience stores and fast food.
  • early food experiences: People who were not exposed to different foods as children, or who were forced to swallow every last bite of overcooked vegetables, may make limited food choices as adults.
  • habits: It’s common to establish eating routines, which can work both for and against optimal health. Habitually grabbing a fast food sandwich for breakfast can seem convenient, but might not offer substantial nutrition. Yet getting in the habit of drinking an ample amount of water each day can yield multiple benefits.
  • culture: The culture in which one grows up affects how one sees food in daily life and on special occasions.
  • geography: Where a person lives influences food choices. For instance, people who live in Midwestern US states have less access to seafood than those living along the coasts.
  • advertising: The media greatly influences food choice by persuading consumers to eat certain foods. In modern society the foods that have larger advertising campaigns tend to be products of larger corporations and in general have worse nutritional content ie. McDonalds Big Mac vs. a local grown apple.
  • social factors: Any school lunchroom observer can testify to the impact of peer pressure on eating habits, and this influence lasts through adulthood. People make food choices based on how they see others and want others to see them. For example, individuals who are surrounded by others who consume fast food are more likely to do the same.
  • health concerns: Some people have significant food allergies, to peanuts for example, and need to avoid those foods. Others may have developed health issues which require them to follow a low salt diet. In addition, people who have never worried about their weight have a very different approach to eating than those who have long struggled with excess weight.
  • emotions: There is a wide range in how emotional issues affect eating habits. When faced with a great deal of stress, some people tend to overeat, while others find it hard to eat at all.
  • green food/sustainability choices: Based on a growing understanding of diet as a public and personal issue, more and more people are starting to make food choices based on their environmental impact. Realizing that their food choices help shape the world, many individuals are opting for a vegetarian diet, or, if they do eat animal products, striving to find the most “cruelty-free” options possible. Purchasing local and organic food products and items grown through sustainable products also helps shrink the size of one’s dietary footprint.

People choose a vegetarian diet for various reasons, including religious doctrines, health concerns, ecological and animal welfare concerns, or simply because they dislike the taste of meat. There are different types of vegetarians, but a common theme is that vegetarians do not eat meat. Four common forms of vegetarianism are:

  • lacto-ovo vegetarian: This is the most common form. This type of vegetarian diet includes the animal foods eggs and dairy products.
  • lacto-vegetarian: This type of vegetarian diet includes dairy products but not eggs.
  • ovo-vegetarian: This type of vegetarian diet includes eggs but not dairy products.
  • vegan: This type of vegetarian diet does not include dairy, eggs, or any type of animal product or animal by-product.
