Why We Eat What We Do

Social, Psychological, Philosophical, and Physical Factors That Drive Our Food Choices

There are many factors that influence the choices we make regarding nutrition. "Social, psychological, philosophical, and physical factors all influence how you choose the foods that you generally eat (Sizer & Whitney, 2011, p. 12). It is vitally important that we understand what these are so that we can better understand why our diet is what it is and from how to go about successfully altering those behaviors if need be. 

Social Influence

Social influences extend beyond just the immediate connections and relationships that you may have with friends, although these influences cannot be ignored, social media has largely affected the standard American dietary habits through commercials and advertisements that sell food options filled with unhealthy ingredients. What we eat in these social settings, such as restaurants, we carry with us back to the dinner table in our own homes. Unfortunately, these businesses are only catering and listening to exactly what the people want - more bang for the buck. By acting on what the public wants, restaurants now provide inflated portion sizes filled with calories to keep consumers happy and coming back for more. At the same time this sets a standard for serving size that is only acceptable that these sizes are matched at home as well. 

Psychological 

We have all experienced hunger - when eating anything will suffice. However, cravings are slightly different because we want something specific, like a cheeseburger for example. At this point a vivid mental image may even be present and this mental imagery uses cognitive resources and brain power. Fortunately, the link between food cravings and what the body actually needs can be as simple as a single nutritional element. For example, someone has a craving for salt and vinegar potato chips and feel as though they need to get these specific chips visualized in their mind in order to fill their craving. What the body is really trying to say is that it needs sodium or that there is possibly a mineral deficiency. Understanding these cravings can allow you to make healthy alternative sources that will still provide the body with what it needs and not what you think you want. Furthermore, the wants and desires to eat can be fueled by a poor relationship with food where food makes up for a lack of something else in ones life and can be a result of emotional eating from a poor relationship for example. Furthermore, there can be a positive or negative association with food that controls ones food choices and can lead to poor habits formed. Lastly, and perhaps most importantly due to its leading cause of food choices is our sensory aspects. "Taste prevails as the number-one factor driving food choices by U.S. consumes" (Sizer & Whitney, 2013) with cost following as second. In all respects, taste essentially encompasses all sensory functions produced by the ingestion of food included smell and texture and is often associated and though to influence spontaneous food choices, or in other words cravings. 


Food For Thought

There are many arguments that surround the food industry and many individuals who hold strongly to their beliefs whether their fighting argument be the taste of certain foods, nutritional value,
culture/tradition, or religion/spirituality, peer pressure, or advertisements. These factors, or beliefs, affect what people eat on a daily basis. One of the leading arguments is by those who believe animals should not be used for human nutritional means because of animal rights, animal suffering, virtue and environmental harm. Those who agree with this support their beliefs by choosing not to include meat in their diet. Regardless, a healthy diet requires amounts of nutrients including protein, iron, zinc, vitamin B12 and calcium which can all be found from meat sources. My point here is that if one chooses to exclude a certain food source from their diet that provides them with essential nutrients then those nutrients must be accounted for by some other form of food - such as plant proteins for those who choose not to eat meat so that protein intake can still remain sufficient. 

Physical Factors

Studies have confirmed that satisfying hunger has many dimensions, including physical.  With limited amounts of money to spend on food in struggling economic times people may avoid spending excess money on more expensive, and often healthier, food choices but focus more on what can feed a family for as little cost as possible, which tends to be food that is easily accessible and available to their locality. While cost and sustainability both play a factor, location also dictates what people choose to eat due to accessibility, which often goes hand-in-hand with cost; the further the product must travel the more the food may cost. Lastly, education and knowledge of nutritional concepts influence the behavior of food choices knowledge alone does not directly result in action if one does not know what action to take. Becoming educated and knowledgable about health concepts will gain confidence in one that they know how to make proper and healthy minded food choices that benefit the body.

Precision Nutrition

A healthy diet can be defined in almost an infinite amount of ways. That being said, however, there are characteristics that all healthy diets follow and are relevant to. Research has given us solid data that shows certain components of a diet that are considered healthy and since national recommendations have been established respectively. So while a healthy diet may cover a wide variety of food and eating habits, there are still those that are continual throughout the spectrum.

Bring Fresh Fruits and Vegetables Into Focus    

The Dietary Guidelines recommend that Americans consume 2 cups of fruit and 2 1/2 cups of vegetables each day. See  Dietary Guidelines here. Collectively, fruits and vegetables provide both vitamins and minerals needed for proper body function. Individually, dark greens are high in vitamins C and K, potatoes and bananas provide potassium, berries are rich in vitamin C, and fruits and vegetables are also high in fiber to promote a healthy digestive system while also providing a low calorie addition to any diet.

Health Gains From Whole Grains

   Whole grains are a necessary part of a nutrient rich diet. The goal is to minimize refined grains like those found using processed ingredients such as white flour and maximizing whole grains like those found in whole wheat bread, black rice, oats and even popcorn. In addition to providing another source of fiber, whole grains are also a source of vitamin E and have been associated with lowering risks for cardiovascular disease. It is recommended that adults indulge in 6 to 8 ounces of grains each day - focusing on whole grains of course. See more on whole grains and their health benefits here.

Limit Processed Foods

If it is in a package...its probably not healthy. Most items found in packages are designed for shelf life and for this reason are high in sodium, additives, preservatives, sugar, and unhealthy fats. A healthy diet, therefore, focuses again on fresh food choices while avoiding those prepackaged meals. If no other choice is available, choose ones you fully know and understand the ingredients in - the fewer the better. In other words, if you're food can go bad then its probably good for you, if it can't go bad it's more than likely bad for you. 

                          Fat Facts

You have heard the saying that your body is a temple...however some find there body has become a prison for fat that cannot escape - ever. Truth be told not all fat is bad and
does serve its part in proper body function. The others - well they can be sent off to a maximum security prison elsewhere. 

Facts:
  • fat should make up for no more than 25 to 35% of total caloric intake per day
  • saturated fat should make up less than 10% of caloric intake 
  • Increase polyunsaturated fats for a healthy heart (plant-based oils, nuts and seeds)
  • Decrease saturated fats that are found in butter, fatty meats and full-fat dairy
  • limit trans-fatty acids, and especially unhealthy fat by lessening intake of prepared goods

Protein Basics

When choosing proteins, focus on those that are nutrient-dense. Whether you choose to consume meats or or not protein is needed for muscular repair, growth, and normal body function.A healthy diet would reach for lean proteins that also offer the added benefit of additional nutritional properties such as vitamins and minerals. Examples would include poultry, lean cuts of beef and eggs. Furthermore, fishes such as salmon provide essential omega-3 fatty acids. Lastly, protein sources such as beans will also provide a source of fiber while dairy products are best known for their contribution of calcium. See more on healthy protein choices here.

Make the Choice!

Clean Eating Challenge


Improving diet quality is important at any age; you are never too young
and never too old. With the increased knowledge gained from this discussion about healthy nutritional choices and guidelines, the choice to make a change is in your hands. Of course making that change is not always easy and everyone at one point will more than likely face an obstacle or a challenge when making a behavioral change. Are you up to it? We hear all these things about super foods and diets and the benefits of healthy eating. What exactly does that mean? Healthy eating is not about starving yourself or jumping on the new fad diet, it is about making healthy minded decisions that are good for your body. Eating well is not about being the perfect model of health, but by finding and learning about food and their values and how they pertain to you and your body and how to balance them based upon your needs, preferences, culture, society and experience. Then, and only then can you begin to create for yourself a wide variety of healthy nutritional choices that are catered to you. I challenge you to find what influences your personal choices and dietary habit and be to sure to keep an eye out for my next discussion that covers the very factors that drive our food choices.

Disease Proof

For too long the media has produced a debatable view of nutrition and health; a widespread misunderstanding of the link between the benefit of a balanced diet and achieving health -what is healthy and what is not. From this has come misleading diets and fads that are based upon hype and hope with no real scientific data or information to support them. What then can one do to eat their way to health - what is the link between nutrition and health and how does a balanced diet support or hinder our ability to stay healthy and avoid illness?

In this post we will explore the link between a nutritionally balanced diet and health based upon not hype or hope, but scientific data, studies, and scholarly resources that provide a solid foundation for the following suggestions and guidelines. From this one can better understand how the standard American diet (SAD) is detrimental to our health. My only hope is that this will clear the confusion and misconception that so many hold about dietary guidelines so that we as a nation can share and enjoy the benefits of healthy living one serving at a time.

A Healthy Heart Starts With A Healthy Diet

A heart healthy diet is key to improving American health and eating healthier is really easier than you may think. Following simple guidelines set forth by The American Heart Association found here encourage good eating habits that both you and your family can practice.  Simple eating habits such as choosing healthier oils when cooking, limiting the amount of added sugars in your food, to eating more fruits and vegetables all provide a customary lifestyle that can be adopted and passed down from one generation to the next so that we may live longer and healthier lives. 



Diet, Nutrition, and the Prevention of Illness and Disease

The growing epidemic of disease and illness that affect this country is in fact related to dietary and lifestyle changes. Read more here. With changes occurring in industrialization, economic development, and market globalization a rapid change was seen in diet and lifestyle. This is having a significant impact on healthy and nutrition because while the standards of living have improved, so has the availability and diversity of food that is now available to the consumer. Because of this there have been multiple and significant negative consequences due to poor and less than appropriate diet choices and patters leading to an uprise in nutrition related chronic disease and illness. 


A general conclusion of recent studies has only reenforced what experts already knew about the relation between diet and illness and/or disease, but also revealed new findings that suggest diet and nutrition modification could in fact prevent most cases of cardiovascular disease, stroke, diabetes, cancers, dental disease, cataracts, and even birth defects. See more here

More about malnutrition can be viewed here.
Furthermore, studies have also seen detrimental and serious negative affects from malnutrition, or an inadequate or unbalanced diet that can lead to fatigue, dizziness, and weight loss in minor conditions. More severe cases, if untreated, can lead to mental or physical disability, illness, and even death. The simple solution? Eat a balanced diet of nutrition-dense food as will be covered in my following discussion.
