Boost Your Immune System with These Top 7 Easy-to-Find Superfoods


Everybody wants to be healthy and have nutritious food on the table. However, it can be challenging to make that happen when the most nutritious foods seem to be inaccessible because of their price and limited availability. 

The great news is you do not need to look far; many of the superfoods that can boost your immune system are readily available at home and in the nearest markets. 

Here are the top seven superfoods that are easy to find. You can include them in your dishes to improve your total well-being.  

1. Spinach

Do not mistake spinach for kale, although both of them are green and good for the body. Spinach is considered a superfood because it contains numerous vitamins like protein, carbohydrates, sugar, fiber, fat, and water. It is also rich in iron, folic acid, calcium, and vitamins A, C, and K1. 

All these nutrients bring the following benefits to the body:

  • Better eye health
  • Cancer prevention
  • Reduced risk of cardiovascular diseases
  • Improved bone health
  • Healthy blood sugar level
  • Anemia prevention
  • Anti-aging and anti-acne properties
  • Improved brain health 

To enjoy spinach, mix it in a food processor with olive oil for pesto sauce or savor it fresh in a salad. 

2. Sweet Potatoes

Another easy-to-find vegetable that is packed with nutrients is the sweet potato. Munch on it if you need a quick dose of carbohydrates, protein, fat, and nutrients like manganese, potassium, niacin, copper, and vitamins A, C, and B6. 

Here are the reasons why consumption of this superfood is beneficial to your body.

  • It aids in digestion because it is rich in fiber.
  • The vitamin A content ensures healthy vision.
  • The anthocyanin content helps prevent different types of cancer.

You’ll find it easy to create delightful meals out of sweet potatoes. Whether it’s baked, fried, mashed, or mixed together with other ingredients, you’ll enjoy this superfood

3. Buckwheat Pasta

Noodle lovers out there, listen up! Here is a healthier option for your well-loved comfort food: buckwheat pasta. 

This curly noodle contains minerals like potassium, iron, zinc, and magnesium. It also has thiamin, high amounts of fiber, and probiotics, which are not only good for digestion but also bring the following bonuses:

  • Thiamin aids in keeping the heart healthy.
  • The protein in buckwheat pasta helps in muscle health.
  • It helps in maintaining a healthy blood sugar level.
  • It is gluten-free, so it’s friendly to individuals with celiac disease.

With all its benefits to the body, try cooking your next noodle soup featuring buckwheat pasta!

4. Avocado

Do you remember when avocado was a real craze? Everyone made almost all kinds of dishes with avocado

You can’t go wrong joining the bandwagon: this fruit is filled with many vitamins, including potassium, folate, and vitamins K, C, B5, B6, and E. It even has more potassium than bananas! 

Low in cholesterol and high in fiber, avocado brings so many benefits to the body, such as the following:

  • It increases good gut bacteria.
  • It reduces bad cholesterol and increases good cholesterol.
  • Antioxidants found on avocados are helpful to maintain clear vision.
  • It helps you prevent arthritis or manage its symptoms.

Avocado is best served on toast or as a smoothie; you’ll get all this goodness in a bite or sip.

5. Tomatoes

The redness of tomatoes will remind you of the first of the many benefits of this fruit: glowing skin and rosy cheeks. Tomatoes are filled with antioxidants, vitamins C and K, folate, and potassium. They are also rich in lycopene, beta carotene, naringenin, and chlorogenic acid, which bring about the following bodily benefits:

  • Making skin glow
  • Easing inflammation
  • Lowering blood pressure and reducing the risk of heart diseases
  • Reducing the chances of colorectal, prostate, and stomach cancers
  • Keeping the hair, eyes, and kidneys healthy
  • Maintaining strong bones

Make homemade pizza pasta using pureed tomatoes, or eat them fresh by adding them to a salad. 

6. Chia Seeds

Chia seeds are small but terrible, and their use even dates back to the time of the Aztecs and Mayans. You can count on these tiny seeds to give you manganese, magnesium, phosphorus, calcium, fat, protein, and a good amount of fiber. 

When you consume them, the nutrients give your body the following:

  • Healthy heart
  • Strong bones
  • Normal blood sugar levels
  • Achievement of weight loss goals
  • No bodily inflammations
  • Prevention of cancer because of antioxidants

Add them to your drinks or top your cereals and oatmeals with chia seeds to enjoy an immune system-boosting treat. 

7. Tea

There is a wide variety of teas: green, black, oolong, and more. Still, they all can make your health better, especially when consumed regularly. Although there are different kinds of tea, they generally contain antioxidants, iron, vitamin K, and calcium. 

Tea aids digestion, and individuals trying to lose weight rely on it for additional shedding of fat, but here are more benefits of tea:

  • Helps lower cholesterol
  • Prevents the development of heart disease
  • Prevents diabetes
  • Heightens mental alertness with caffeine
  • Strengthens bones and teeth

To get the full benefits of tea, go for the natural ones boiled from fresh tea leaves instead of the instant mixes that are popular these days.
