What Is Clean Eating?
Although there is no official definition of "clean eating", it has been a dietary trend for the past decade. It is more of a lifestyle philosophy rather than a specific diet. The concept of clean eating involves consuming whole foods while avoiding processed and convenience foods for the purpose of achieving better health. Some variations of the diet may also involve excluding gluten, grains, and dairy products, and promoting the consumption of raw foods. Organic and seasonally available food should be the foundations for this way of eating whenever you can source them.
This approach is intended to help the body function optimally and promote overall health and well-being. The danger of consuming processed, chemically-laden foods is that they often lack nutrients and can contribute to the development of chronic diseases such as heart disease, and even cancer. There are several benefits to eating a clean diet, as well as some simple ways to get it done. Let's take a look at these below.
What Are The Benefits Of Clean Eating?
The benefits of clean eating are numerous and include better digestion, improved nutrient absorption, and higher energy levels. Eating clean also helps to reduce your risk of developing chronic illnesses such as diabetes or heart disease, as well as reducing inflammation throughout the body.
Finally, you'll be helping to support local farmers by buying fresh, local produce, which can help to reduce your carbon footprint and provide better nutrition for you.
There are many perks to clean eating, including:
- Naturally supports a healthy weight range
- Increased consumption of fresh, whole foods and pure water boosts energy, brain function and immunity
- Suitable for the whole family
- Simple to follow grocery list that can be affordable (if you keep things simple!)
- Suitable for those following different diets, including vegan, vegetarian, low-carb, gluten-free, paleo, and keto.
How To Adopt a Clean Eating Lifestyle
Some of the best ways to ensure you're eating 'clean' foods is to buy organic produce and avoid pesticide exposure, limit processed foods, and drink plenty of pure, filtered water. This will mean you're supporting your body and mind optimally, maximising your healthy eating habits.
Let's break down the essentials of understanding clean eating: food and water.
Choose Organic Foods & Avoid Pesticides
Introducing the dirty dozen and clean fifteen foods lists. These are two perennial lists that change slightly each year according to data from a US nonprofit, the Environmental Working Group. These lists have frequented the health and wellness industry for the past few years, identifying the most and least chemically-sprayed conventional fresh fruits and vegetables available.
One core problem with consuming foods that have been sprayed heavily with pesticides, herbicides and fungicides, is that these compounds destroy the microbial ecology of the soil within which fruits and vegetables are grown. This also impacts the plant's ability to uptake nutrients from the soil and impairs plant-based communication within the natural ecosystem. (Yes, plants communicate with each other!).
Plants reflect their environment and share information about growth conditions with human consumers, much like the bi-directional communication that occurs within our microbiome. Foods that are grown organically, in micronutrient-rich environments, without the harsh impact of chemicals, can do what they're supposed to do, naturally. Plants will absorb important vitamins and minerals that we can benefit from and enjoy.
Of course, there's an inevitable downstream effect of ingesting chemicals for us as consumers. Our microbiome and subsequently our health is negatively affected by the toxic pesticides in the foods we eat. Research demonstrates that pesticides cause disruptions to our reproductive health and may contribute to cardiotoxicity and cancer.
Here is a list of the most heavily-sprayed fruits and vegetables according to recent data:
The Dirty Dozen
- Green beans
- Kale/mustard greens
This data is based solely on research and studies conducted in the USA. However, it's worth noting that since 8% of Australia's fruit and vegetable imports can come from the United States, these findings still have relevance to Aussie consumers.
For as long as these lists have been in public awareness, there are a few mainstays that reappear each year. Strawberries, apples and spinach have been repeat offenders for the last 5 years, and you should always choose organic varieties if possible.
When you think about it, the foods that bugs love to eat are obviously going to be the ones that are heavily sprayed. Leafy greens, fleshy fruits and berries are favourites for insects and animals alike, which make them vulnerable unless they're sprayed as a deterrent. Foods that have a larger surface area (again like leafy greens) incur more pesticide absorption as a result.
Produce with thin skins, a delicate structure or those that can be easily broken down in the presence of mould, air or water are foods that typically have the highest amount of chemical contamination.
If you are vegetarian or vegan, this list might be worth keeping handy. Use this "the dirty dozen" list as a helpful guide, and you can be sure you're reducing your overall toxic load, which will make you feel healthier in the long run.
An easy way to alleviate worries about pesticides, chemicals and other byproducts of industrial farming, is to purchase your produce locally and ensure that it is certified organic.
The Clean Fifteen
In Australia, there is a valuable body of research and interesting data that supports the consumption of organically-grown, clean foods wherever possible. A study by Dr Liza Oates published in 2013 at RMIT, found that switching to an organic diet for one week can result in a nearly 90% decrease in pesticide levels in adults. The study found that organophosphate levels (pesticide metabolites) in participants' urine were 89% lower after consuming an organic diet for seven days, compared to a conventional diet for the same duration.
It's clear that opting for organic foods supports your clean eating efforts. However, it may not always be affordable or accessible for your entire grocery shop, especially if you're feeding the family. Luckily, there's a list of foods known as the 'clean fifteen', which denotes the least sprayed and least affected by pesticides.
Here is a list of the least-sprayed fruits and vegetables according to recent data:
- Kiwi fruit
- Sweet frozen peas
- Sweet potatoes
In contrast to the 'dirty dozen' food list, the 'clean fifteen' foods are fruits and vegetables that have very low pesticide residue and contamination. Many of these foods have thicker skins which naturally protect the interior from harmful chemicals. You can confidently buy these foods at your regular supermarket or greengrocer, without needing them to be organic.
Drink Pure Filtered Water
If you're not drinking water, there's no way you can be functioning optimally. It's that simple. When the water composition of your blood is 82% water, your muscles are 75% and your brain is 76%, it's clear that water is an essential component of life on earth and an important element to a clean eating lifestyle.
Water delivers nutrients to the entire body, oxygenates your cells, supports elimination and weight loss and promotes increased energy. Not drinking pure, filtered water can impair your brain function and nervous system.
How To Avoid Dehydration
To ensure you stay hydrated, try to drink water before you actually feel thirsty. This will help keep you replenished and feeling your best. The body has specific ways of controlling hydration levels. If water is lost from the extracellular space, water is drawn out from inside cells to balance the concentration. This causes cells to decrease in size, sending a message to the brain that the body is dehydrated, which triggers a thirst sensation.
Recent scientific findings indicate that even mild, low-grade and chronic dehydration could have negative health consequences for most people. Typical signs of dehydration include fatigue, brain fog, anxiety, irritability, muscle cramps, decreased urine output, high blood pressure, headaches, and body aches and pains.
Do you really have skin issues, lymphatic problems and fatigue? Sure, it could be allergies, sedentary lifestyle habits or iron deficiency. But... it could also be that you're just chronically dehydrated. It's such an easy, free fix to increase your water intake to test whether these symptoms are improved or resolved. If you boost your clean water intake and you still experience problems or have other health concerns, it's best to consult a health provider.
If you start drinking water regularly, you also might feel less inclined to consume unhealthy snacks and beverages. The main thing to remember is that attempting to drink 2L of water per day will always do you some good. Your body will appreciate the uplevel as you continue on your clean eating path.
