When starting to eat healthy, the key is to stock up on nutritious food and always add a few superfoods to every meal. These affordable superfoods offer many health benefits without any side effects or breaking the bank.
I have divided these 20 affordable superfoods into categories: Nuts and Seeds, Vegetables, Grains, Fruit and Berries, Herbs and Spices and Drinks.
NUTS AND SEEDS

Seeds and nuts are affordable superfoods that can be sprinkled on salads and sandwiches, mixed in a smoothie, or added to any bakery. I learned A little tip from Tim Spencer: mix different kinds of nuts and seeds in a jar to make it easy to incorporate a variety of them daily.
Nuts and seeds are high in fat, so if you are trying to lose weight, use them in moderation.
Here are nuts and seeds that I always have in my cupboard:
1. Chia Seeds
Nutrition and Health Benefits:
Chia seeds are high in omega-3 fatty acids, particularly alpha-linolenic acid (ALA), which is beneficial for heart health.
They are also very high in fibre (34 grams per 100 grams ), good for digestive health, help lower cholesterol, and regulate blood sugar levels.
Their high protein (17g per 100 g) and mineral content support muscle function and bone health.
