Why your nutrition is so important

The importance of nutrition and its role in health and fitness cannot be understated and will by most professionals be considered the most important factor of our current state or our potential for change. There is a well know expression that says “you are what you eat” and while this is not meant figuratively, it does well to picture the depth of how nutrition affects us.

The primary role of food and beverages are to nourish the body. When reviewing the term “nourish” you will find the following: “a means to supply what is necessary for life, health and growth”, “to cherish, foster keep alive” or “to strengthen, build up, or promote”. Powerful words and concepts like these are sometimes too abstract to comprehend so in this article the goal is to elaborate on some very relatable areas of our lives that have direct correlations to our nutritional status. The outcome goal of this article is to increase your awareness of nutrition’s importance and hopefully push your daily eating habits up the priority list for better choices and a healthier and happier you.

 Without further ado, here are 11 key areas that are heavily affected by our nutritional habits.

1. Weight control & Lifestyle diseases

In most modern societies we have access to an abundance of cheap, highly processed foods that are dense in energy (calories) and low in nutritional quality. This combination is often accompanied by ingredients that are highly palatable (tasty) and low in satiety (don’t make you full) which increases our desire to eat more. If you live a sedentary lifestyle and the majority of your diet consists of processed foods then you will very easily consume more energy from your food than you expend during a day or a week. This additional energy is stored by the body as fat for later use, but over time there are many deleterious effects of being overweight.

We have reached a time where more deaths occur from overweight related diseases than underweight related conditions[i]. The absolute majority of these are preventable through a change in eating habits[ii]. Obesity in itself substantially increases the risk for our biggest modern day killers, heart attacks and strokes (CVDs), some cancers, diabetes, and high blood pressure. There are a host of other diseases that are associated with obesity such as asthma, liver and gallbladder diseases, sleep apnea, osteoarthritis and gynecological complications[iii],[iv].

Obesity also manifests itself as mental illness such as clinical depression and anxiety, bodily pain and difficulty with physical function, all resulting in a reduced quality of life [v],[vi],[vii].

2. Physical performance (strength and endurance)

Without adequate fuel and hydration sources (carbohydrates, fats, protein, water and minerals) our ability to perform in any physical activity will quickly diminish. If we lack adequate protein our ability to rebuild our muscles and connective tissue will suffer, our recovery from physical activity will be prolonged and risk of injury will increase. With insufficient glycogen (carbohydrates) we will struggle to do high intensity work. The specific requirements of your nutrition will be based on the type and duration of the activity you are doing as well as individual needs and goals. If you want to build/maintain muscle mass, improve your cardiovascular endurance or just your overall fitness, you need to make sure you are fueling yourself adequately. 

3. Energy levels

The food we eat provides us energy in the form of fuel (carbs, fat and protein) as well as aiding in the energy forming processes from the fuel (vitamins, minerals and enzymes). Obviously if we do not eat or drink enough then the overall fuel sources drop and we will get tired. When we eat and drink items with poor quality fuel and micronutrients (highly refined and processed foods and drink) we are not able to maximize the utilization of the energy. These same food types can distress our guts and create digestive inflammation that lead to low energy levels. Removing any provocative foods or drinks for your gut and eating plenty of nutrient dense food (fruits, vegetables, nuts, fish etc) will be a good starting point for improving your energy levels[viii].

4. Digestive health

Our digestive system is the access point for nutrients to enter our bodies and it’s importance in our health and performance cannot be understated. It not only breaks down the food we eat, it is also the main storage of our immune system. If the digestive system suffers then all other organs in the body will suffer as they rely on the nutrients that are filtered through the intestinal walls. The modern food revolution has provided us with an abundance of choice and quantity, sometimes at the cost of the quality of the produce. If we eat food types or produce that we are not genetically suitable to or that we become intolerant to then we can create a leaky gut syndrome or inflammatory bowel disease that can lead to other autoimmune disorders and inflammation around the body. The key again is to focus on natural, unprocessed foods while listening to your bodies responses to various food types. If what you are eating is causing you to feel bloated, nausea, lethargic or gives you “brain fog” then you should probably avoid them.

5. Brain health & performance

Most of us have experienced having nervous “butterflies” in our stomachs or getting nauseous from uncomfortable situations. The reason this happens is due to our guts being sensitive to emotions and being intimately connected though what we call the brain-gut connection. Just by thinking of a meal the stomach and other digestive organs start to prepare by creating various secretions to break down the food. The connection goes in both directions and if your gut is under distress from poor diet, infections and stress then this could result in anxiety, stress or depression. A stressed mental state can also affect movement and contractions of the bowel making things worse and a negative spiral can occur[ix].

Did you know your brain is made of primarily fat and water? In order to maintain optimal brain health & performance as we age we need to provide it with an environment where it receives the necessary oxygen, nutrients and recovery (sleep) to perform its daily tasks. One of the most profound nutrients for our brain is Omega-3, a form of fat found in fat fish as well as some seeds and nuts. The many positive associations of Omega-3 consumption and brain health and performance are well documented:

·     Fights age-related mental decline like dementia and alzheimer’s[x],[xi],[xii]

·     Fight depression and anxiety[xiii],[xiv],[xv]

·     Increase memory, problem solving, communication and social skills[xvi],[xvii]

·     Decreased risk of ADHD, autism and cerebral palsy[xviii]

6. Mood

Everyone has experienced being “hangry” before, an angriness or short temperedness driven by hunger. Low blood sugar causes your brain to experience a lack of energy and it’s telling us we need to get fuel ASAP. Withholding fuel from the brain can create mood swings and anxiousness and ultimately leading to poor decision making. Waiting for too long to eat or “Just grabbing something quick and convenient” is a common behavior that often leads to “hangriness” followed by poor food choices and only a short term energy fix. Smart planning ahead of time is essential for making better food choices available and keeping your body and mind happy and productive[xix] 

7. Joint disorders

Joint inflammation and pain is often a result of autoimmune disorders which are closely linked to gut leaking and inflammation. The underlying cause can in many cases be food intolerances that over time irritate the gut and create inflammation and “leaky gut” (increased gut permeability), meaning larger food particles enter the blood stream and create an over-exaggerated immune response that ends in the body attacking its own cells.[xx],[xxi]

Inflammation from metabolic disorders (i.e. high blood sugar and blood fats) can also create pain and bone distress through damage to the blood vessels and nerve cells surrounding the bones.[xxii],[xxiii]

8. Immune system

Did you know that our digestive system (GI tract) hosts over 70% of our immune system! Nutrient-dense, fiber-rich whole foods tend to promote a healthy bacterial balance, whereas a diet rich in processed foods, fats and sugars can lead to dysbiosis — otherwise known as microbial imbalance. The healthy bacterial in our gut helps prevent harmful bacteria from entering our blood stream or populating itself. In the case of dysbiosis or undernutrition/malnourishment it is harder to keep these bad bacteria at bay. A balanced whole foods diet is your best insurance against all kinds of viruses and infections.[xxiv]

9. Skin care

 Our skin is often talked about as the reflection of our gut health, meaning any distress in the GI tract will show itself in the skin as one of the many forms of skin disorders, from acne, rashes, inflammation and dryness. Certain nutrients can even have therapeutic effects on skin disorders and aid in protection against ultraviolet light (sun rays).[xxv] To maximize the care of the outside of your body you need to first make sure the inside is taken care of.

10. Reproduction

Infertility is becoming an increasing problem in particular in developing countries. As most disorders this is at large a multifactorial scenario where environmental, hormonal and nutritional cues are at play, but there is an increasing awareness of the role that nutrition plays in providing the best possible conditions for female reproduction. Many nutritional states could influence female reproductive health being under- and over-weight, obesity, digestive disorders and hormonal disruption, impairing women fertility.[xxvi]

In men obesity is closely related to low testosterone levels and poor sperm quality, placing a burden on their reproductive role also.[xxvii]

11. Longevity

Who does not want to live a long, fulfilling life? Can our diet impact how long we live? Well if our diets and lifestyles create the majority of the main diseases and killers in society today then obviously not dying prematurely from dietary related illness is the first step. But in the absence of disease can our diets be the fountain of youth that we all seek? The closest we can come to answering that question is by looking at the populations in the world that live the longest and study their lifestyle and dietary habits. These populations live in what we call the Blue Zones. Here are some of the dietary habits of the Blue Zone centurion’s.

·     Caloric restriction* – Stop eating when your stomach is 80% full to avoid overeating.

·     Plant dominant diets – Plants, rice, nuts and beans primarily.

·     Protein restriction – Meat no more than once per week.

·     Energy timing – Smallest meal of the day in the afternoon or evening.

 *Caloric restriction has been shown to improve the health of the mitochondria (power and energy station) in our cells.

Summary

There is no doubt that the food we eat has the ability to sway us between high levels of health, wellness and performance to the lowest levels of disability and illness. No one meal will make you healthy and no one meal will make you sick. It is your habits over time that will shape how you will benefit or suffer from your dietary habits. Eat as much non-processed, natural food as possible and observe and listen to your body. If you do not feel great after your meals, maybe it is time to make some changes.

 Wishing you a more informed and nutritious perspective.
