We live in a unique time where the so-called developed world has access to an unprecedented abundance of ready to eat food, right at our doorstep. We have endless choices: we can buy all sorts of fruit and vegetables regardless of seasons and countries. As a consequence, our shopping and eating habits have been affected.

We buy and throw more food than ever!

Sadly, there are many downsides to this including the creation of waste produced by food scraps going to landfills.

Our lives are busy. Most adult-age members of the family work outside the home compared to previous generations. It is no surprise that we don’t have the time (and let’s face it, the energy) to prepare homemade food so we constantly buy ready-to-go meals from supermarkets and restaurants (including fast-food chains). 

Even when we can cook, the way of preparing it and consume it that was common until the last century is now somewhat passé: thanks to refrigeration we have the ability to store food, we have huge retailers where we can do our one-stop-shopping and buy endless amounts of food and quicker and cheaper transportation means we can buy food from other parts of the world en masse.

We (yes, myself included) end up buying throwing away food like never before in history, as well as discarding perfectly edible parts of fruit and vegetable just because we don’t know how to use them. 

I had a chat with my friend Alba* about this and was so impressive by the amount of tips she had that I decided to post here! I hope you enjoy!

Why should we reconsider our eating habits? 

The food, or part of it that we bin, don’t just disappear into thin air.

Food waste produces methane – a powerful greenhouse gas!

Discarded food is sent to landfills, where it rots and produces methane gas, which is the second most common greenhouse gas and much more powerful gas than carbon (CO2).

Tossing food is not only detrimental to the environment but to our wallets as well. While composting can minimize this impact, not everyone has taken to it! 

Adopting a no-waste lifestyle is a great way to save more money as well as being kinder to mother earth.

What is the best way of going zero waste?

A good way to start reducing food waste is to limit our grocery shopping to what we need.

Spending a few minutes to plan a weekly menu is key: by scheduling what you are going to eat for the whole week, you can shop more responsibly and it will help you to prevent food from expiring in the fridge.

Another great trick is to check the fridge and cupboards before going to the grocery store to avoid buying something you already have and make an “Eat me first” box in the fridge for anything close to the expiry date to cook it before it goes bad.

Stick to your list when you are going out shopping

Invest in some useful kitchen tools such as a slow cooker, so when you are not in the mood for cooking or you don’t have the time you can throw everything in your crockpot and it will make a healthy meal for you.

Batch cook on your days off

Having ready homemade meals in your freezer that you can easily reheat when you need to is very convenient.

Cooking in batches can help to reduce food waste

On top of that, batch cooking is a lifesaver if you have food about to expire but that you can’t immediately eat.

Practical hacks to use food scraps

I am going to share with you some clever ways to reuse food scraps that you might not have heard of.

For years I thought that fruit skin and vegetable leaves and peels are not good to eat and therefore I was guilty of throwing them away. 

On the contrary, almost any vegetable leaf is edible and using it in the kitchen will stimulate your creativity and allow you to experiment with new yummy recipes.

Since I embraced minimalism and intentional living, I also started to buy organic seasonal food, not only to have less impact on the planet but also to save money and to get all the health benefits of eating clean.

Organic and seasonal fruit and vegetables are a better choice also because you can use peels and leaves without worrying about pesticides and nasty chemicals and they don’t come in plastic packaging. 

How to repurpose citrus peels

You can also utilize citrus peels to make multipurpose cleaning detergent

Place the candle wax in a bowl and microwave it until melted.

Pour the melted wax into the citrus bowls with wick positioned vertically in the centre.

Let cool and harden completely.

Drain them one by one with the help of a fork and put them in a bag (or a container that has a lid) with sugar in it and shake them.

Let them dry completely for a couple of days and enjoy!
