Have you ever found yourself reaching for the same foods over and over again every single day? Cereal for breakfast every day is convenient; however, it’s important to maintain a variety of foods in the everyday diet. There are a number of things you can do to switch up your usual diet. Wait! But why? The benefits of eating a diverse diet include positive health outcomes, cultural preservation, and support for biodiversity. 

    First and foremost, enjoying a diverse diet helps to ensure you meet nutrient needs. By eating a wide variety of foods, you are exposed to a full range of vitamins and minerals, which is vital for optimal health. Approximately 2 billion people worldwide struggle with nutrient deficiencies, which is shockingly high, but a problem that can be solved by increasing diversity in our diets. Studies suggest that diets that include many different foods help prevent nutrient deficiencies and even reduce the risk of illnesses, ranging from diabetes to depression. Additionally, plants provide bioactive compounds that have been shown to reduce inflammation and support immune function. Some foods that you can include in your diet in order to achieve such benefits include lentils, avocados, chia seeds, salmon, and many more. Most importantly, by focusing on eating a variety of foods from different food groups, including proteins, fats, carbohydrates, as well as many vitamins and minerals, you too can reap the benefits of a diverse palette.

    Secondly, eating a variety of foods is beneficial because of the cultural preservation it provides. Food is essential to everyday life, and individuals' food choices often reflect their cultures, shaped by the foods they have been exposed to. By experimenting with different dishes from around the world, you can support the traditions of other cultures around the world, keeping them alive and flourishing. By choosing foods that reflect your cultural identity, you can learn about your own food traditions and maintain the wisdom of your ancestors. Factors such as the increase in processed foods and dietary standardisation have contributed to the decline in the consumption of traditional foods. That is why it’s extremely important that we hold on to traditional food practices in order to preserve our cultural roots. 

    Finally, a variety of food in the everyday diet is beneficial because it supports biodiversity. Diets rich in grains, vegetables and fruits, proteins, and more help support local biodiversity by supporting all life on earth. About one-third of the population says a healthy diet is unaffordable. However, by consuming foods grown locally in our communities, we can help reduce food insecurity, so that everyone around the world has access to the basic human need for food. Being more experimental in our diets increases the variety of foods we consume and grow, contributing to sustainable agriculture. Eating a wider variety of fruits and vegetables helps our planet in many ways, including reducing water use and lowering greenhouse gas emissions. It’s evident that varying the diet helps combat food insecurity and helps with the biodiversity of the Earth. 

    In conclusion, increasing the diversity of our diets is beneficial for our health,  which helps preserve cultural traditions and supports biodiversity. So, now that it’s clear why you should expand your palette, what can you do to add variety into your meals? You can increase diversity in your diet in a number of ways, one being by exploring new items during your next grocery visit, and adding new items to your cart. You can also visit local restaurants that you haven’t yet tried, experimenting by ordering dishes you wouldn’t usually. Another way is to search for new recipes, either online or the old-fashioned way, with a recipe book. Now, the next time you get offered a new food to try out, give it a chance. Your plate is like a passport — the more cuisines and different foods you explore, the richer your body’s library of nutrients becomes.
