What is the Rainbow Diet?

In a world full of dietary trends and fads, meet the Rainbow Diet. It's not as complicated as it sounds and no, we are not asking you to chase the skies for the perfect rainbow. Rainbow Diets are a refreshing and timeless approach to healthy eating. This colourful and vibrant diet revolves around the concept of consuming a wide variety of rainbow-coloured fruits and vegetables everyday. These colourful fruits and vegetables contain phytonutrients, compounds that give plants their rich colours as well as their distinctive tastes and aromas. Phytonutrients also strengthen a plant's immune system. They protect the plant from threats in their natural environment such as disease and excessive sun. When humans eat plant foods, phytonutrients protect us from chronic diseases.

It is essentially a celebration of nature's abundance, where you fill your plate with foods of various colours from the entire spectrum, the darker and more vibrant the colours from your foods, the better are the nutrients from them.

The idea behind it is that colourful vegetables and fruit contain specific micronutrients that support your health and combat biological stress with antioxidants and anti-inflammatory molecules. This type of biological stress affects your body at a cellular level — known popularly(or unpopularly) as “oxidative stress”, which is caused by free radicals. Fortunately, the antioxidants in rainbow diet foods help the body to neutralise free radicals and stop them from damaging your cells.

Free radicals are generated by your metabolism (the life-giving chemical reactions inside your cells) and your environment. Some common sources of free radicals in everyday life are Mitochondria, Inflammations in the body, Exercise (every action has an equal and opposite reaction), Cigarette smoke and Air pollutants, Pesticides, radiation from electronics, industrial solvents that are in most of our everyday household products.

The rainbow diet nutrients don’t act directly on free radicals. Instead, they prompt the body’s natural antioxidant mechanisms, which increases the body’s natural ability to reduce oxidative stress. It also has a few other great benefits too, like fibre. Plant foods are full of fibre, and fibre is what keeps your digestive system running optimally. Plus, fibre and other plant nutrients act as prebiotics: food molecules for your gut bacteria that also help keep you healthy. So always a win win!

Benefits of Eating a Rainbow Diet

Rainbow foods, as the name suggests, encompass a spectrum of colours that represent different nutrients and health benefits. Here are some compelling reasons why you should embrace all the colours! Each colour provides a variety of health benefits and no one colour is superior to another, which is why a balance of all colours is most important. Getting the most phytonutrients also means eating the colourful skins, which are the richest sources of the phytonutrients, along with the paler flesh. Try to avoid peeling foods like apples, peaches and eggplant, that's where the pigments are the most concentrated source of beneficial nutrients.

1. Nutrient Diversity: Rainbow fruits and vegetables are rich in a diverse range of vitamins, minerals, and antioxidants. Each colour group offers unique health benefits, micronutrients, and nutrients, making it essential to incorporate a variety of them into your diet.

2. Antioxidant Power: Many of the vibrant hues in rainbow foods come from antioxidants such as beta-carotene (found in orange and yellow foods), anthocyanins (abundant in blue and purple foods), and lycopene (present in red foods). These antioxidants help combat free radicals and reduce the risk of chronic diseases.

3. Enhanced Immunity: The phytonutrients in coloured fruits and vegetables support a robust immune system, helping your body fend off illnesses and infections.

4. Digestive Health: Fibre is a crucial component of a healthy diet, and coloured foods, particularly greens, are excellent sources of dietary fibre. They aid in digestion and promote a healthy gut.

5. Healthy Skin: Antioxidants and vitamins found in coloured plants, veggies, and fruits can improve skin health, giving you a stronger and healthier skin barrier.

6. Weight Management: Rainbow foods are typically low in calories and high in fibre, making them ideal for weight management and maintaining a healthy body weight.

7. Reduced Risk of Chronic Diseases: Consuming a wide variety of colourful foods has been linked to a decreased risk of chronic conditions such as heart disease, diabetes, and certain types of cancer.

Now that we've explored the benefits of eating the rainbow, let's see how you can incorporate these colourful foods into your daily meals.
