On Earth Day: Better health for you and the planet

brain health environment healthy eating healthy living immunity real food resilience Apr 22, 2023

I’m becoming more and more conscious about how interconnected we truly are–all people, animals, plants and indeed with Mother Earth herself. On a physical level we all coexist in the same environment–and anything in our external environment is shared with each of us internally.  And ultimately we are connected energetically, because on a quantum level, we are all simply forms of energy.  

This means that how we interact with the environment, including how we grow, raise, harvest, distribute, store, deal with waste, and ultimately consume our food, will impact the environment.  Our food comes from the earth, so the healthier she is, the healthier our food is. 

A lot of research shows that making more nutritious food choices corresponds with making sustainable food choices. Healthy, unprocessed, Real Foods are easier on the environment. And preventing food waste is also sustainable and helps you save money, too. It’s fascinating how one decision about our next meal can have several positive effects!  I can only imagine the impact making those decisions every day can have on our planet over the upcoming weeks, months, and years. I believe that each of us making individual choices can make a difference when those choices are repeated over and over again.

This is what inspired me to share my 3 upcoming articles all about sustainable food. I wanted to discuss the best strategies on how to make better choices at the grocery store and market, and how to reduce food waste at home, all while becoming healthier.

Find out about how choosing nutritious and sustainable foods, and enjoying them while minimizing waste feels so empowering!

Part 1 - We are all connected to the earth and her ecosystem!

What is one thing every single person does that intimately links our health to the environment? 

We eat!

We are interconnected with our ecosystems, nature, and the Earth. When things start deteriorating outside us, it affects us internally. The changing climate impacts weather patterns that can cause floods, droughts, excessive heat, extreme weather events, and food and water insecurity—all of which can affect our health. Some examples of health effects that have increased risks linked to environmental changes and extreme weather events are:

  • Heart and respiratory diseases[1]
  • Gestational diabetes[2]
  • Adverse mental health outcomes (such as suicides and self-harm, mood disorders, schizophrenia, neurotic and anxiety disorders, and other conditions caused by the gradual decrease in the functioning of the brain)[3]
  • Several different types of infections (such as lyme disease[4], cholera[5], dysentery[6], malaria, and dengue).

Our actions influence our world and there are many things we can do to prevent or slow climate change. For example, we can turn down our air conditioners and buy a more fuel-efficient car so we use less fossil fuel. We can reduce the number of items we purchase, especially those with excessive packaging and that have traveled a long way to get to us. We can sort our waste by reusing and recycling everything possible.[9] 

And you might be surprised to know how much our food choices can make a difference, too.

Agriculture’s environmental impact

Growing food has a very large environmental impact. How we farm affects the land, water, and air.[4] According to a review study in the journal PLoS One, agriculture uses more than 33 percent of cultivable land, 70 percent of our use of freshwater, and contributes up to 30 percent of human-produced greenhouse gases.[10] The more land and water we use, and the more greenhouse gases we release, the more we negatively impact the health of Mother Earth. This contributes to more climate change, reduces biodiversity, and increases soil degradation and freshwater scarcity.[10] As you’ll soon see, one food has the biggest impact on our land and freshwater use and greenhouse gases.[9,11].

Then, vice versa, the weather patterns and climate affect how we grow food. In areas that are becoming drier, more water is needed. Not to mention the widespread crop destruction from extreme weather events or pests that are flourishing now more than ever!

It’s clear that we are truly interconnected with the planet, and our food choices can have enormous influence because foods that are healthier for us—like fruits and vegetables—are also healthier for the environment. Win-win!

We can all tread a bit more lightly on the Earth and make sustainable choices that reduce negative health outcomes for us and the nature all around us.

One unusual tip to live more sustainably

Before we discuss some of the small and uncomplicated food choices that can effectively improve your health and the planet’s health, I want to share an interesting way to live more sustainably: practice gratitude. New research shows that when people feel grateful for what they have, they’re less likely to take more resources than they need.[12,13] You can do this by regularly remembering times you felt grateful, using a gratitude journal, or trying gratitude meditations. 

Also consider sharing your sustainable actions with friends, family, or on social media to set an example, show your leadership, and encourage others to do the same. The more people that contribute, the better off we’ll all be. 

The two sustainable food habits that make the most difference

There are so many aspects of what we eat that it’s hard to know what makes the most difference. 

  • Is it eating locally produced food? 
  • Food that’s in season?
  • Food that’s unprocessed? 

All of these options are going to have some benefits. The question is: Which food strategies have the biggest benefits for the climate?

The good news is that making more sustainable food choices can be as simple as 

  1. swapping some servings of the bigger impact foods (like highly processed beef) with more climate-friendly options (like vegetables, biodynamic farm-raised animals or plant-based proteins (such as lentils, legumes, or fermented soy products)[11], 
  2. buying only what you need, and reducing food waste. 

The next important consideration, whether you are a meat eater or wish to be plant-based, is to choose Real Food.  And by choosing food that is raised and grown under the healthiest of conditions (see my blog from last week on biodynamic farming HERE).  This means NOT eating processed foods like “fake meat” burgers, highly processed meat products like wieners, or industrial seed oils like canola.

Over the next couple of weeks, I’ll talk about the two main areas where we can make the biggest positive impact.[14] 

  1. The first is choosing what to buy and how much. 
  2. The second is all about how you can reduce the amount of food that goes to waste in your home and community.
