Boost Your Immune System: The Best Foods and Supplements to Fight Off Flu Bugs and Colds

As the cold and flu season is here, it’s essential to strengthen your immune system to ward off pesky viruses. 

While good hygiene and adequate sleep play crucial roles in staying healthy, your diet can also be a powerful tool in preventing and fighting colds and flu. 

Here are the best foods and supplements to incorporate into your routine for optimal immunity.

Incidentally, nothing is guaranteed 100% and even though my wife and I follow these tips we came down with an infection that laid us low, which is why blogging activity has been severely curtailed, recently! Hopefully a normal service will be up and running soon.  

Immune-Boosting Foods

1. Citrus Fruits

Oranges, lemons, limes, and grapefruits are packed with vitamin C, a key nutrient that helps boost white blood cell production, which is vital for fighting infections.

2. Garlic

Garlic has powerful antimicrobial properties due to its high allicin content. It has been shown to reduce the severity and duration of colds while also enhancing the immune response.

3. Ginger

Ginger is well known for its anti-inflammatory and antioxidant properties. It can help relieve sore throats, combat nausea, and may have antiviral benefits.

4. Yoghurt

Probiotic-rich foods like yoghurt help balance gut bacteria, which play a crucial role in immune function. A healthy gut microbiome supports better resistance against infections.

5. Leafy Greens

Spinach, kale, and Swiss chard are rich in vitamins A, C, and E, along with antioxidants that support immune health and help the body fight off infections.

6. Nuts and Seeds

Almonds, sunflower seeds, and walnuts are packed with vitamin E, zinc, and healthy fats that help maintain a robust immune system.

7. Chicken Soup

There’s truth behind the old remedy—chicken soup contains amino acids and minerals that support immune function and help alleviate cold symptoms.

8. Turmeric

Curcumin, the active compound in turmeric, has strong anti-inflammatory and immune-boosting properties, making it a great addition to your diet.

Beneficial Supplements

1. Vitamin C

Vitamin C supplements can help reduce the duration and severity of colds by enhancing immune function.

2. Vitamin D

Low vitamin D levels are associated with increased susceptibility to infections. During the winter months, supplementing with vitamin D can help keep your immune system strong.

3. Zinc

Zinc is crucial for immune function and has been shown to reduce the length of colds when taken at the first sign of symptoms.

4. Elderberry

Elderberry extract is packed with antioxidants and has antiviral properties that may help prevent and shorten the duration of colds and flu.

5. Echinacea

Echinacea supplements may help boost immune function and reduce the risk of catching colds.

6. Probiotics

Probiotic supplements help maintain a healthy gut microbiome, which is essential for a strong immune response.

Final Thoughts

No single food or supplement can guarantee immunity from colds and flu, but incorporating these immune-boosting options into your daily routine can significantly improve your body’s ability to fight infections. Combine them with proper hygiene, adequate rest, and regular exercise for the best defence against seasonal illnesses. Stay healthy and flu-free this season!

Boost Your Immunity With the Winter Watercress Challenge

Did you know that by eating or one bag of watercress a week you can supercharge your health and immune system this winter? 

The Watercress Company, the UK's largest grower of watercress is encouraging us all to eat more of the nutrient-packed leafy green in their Winter Watercress Challenge.

Watercress is a winter superfood. Just one nutrient-packed bag of watercress a week (or more if you like) is a step in the right direction to give your immune system the tools it needs to do its job effectively.

According to the nutrient density index, watercress hits the maximum score of 1000¹, putting it in joint first place with kale and way ahead of other well-known superfoods like blueberries, edamame, broccoli or spinach.

Just 100g of watercress contains more than half our recommended intake of vitamin A, which is required for a strong immune system, as well as improving iron absorption.

Gram for gram, the plant contains more vitamin C than an orange, which also helps us to absorb iron more efficiently, more folate than a banana and more vitamin E than broccoli. This all contributes to a robust and resilient immune system, enhancing your ability to defend against illnesses.

Award-winning registered nutritionist, Dr Lucy Williamson says, “The key to a good diet is eating a variety of 30 different plants a week (don't worry, that includes spices, nuts, pulses and herbs too). Just including watercress once a week is a fantastic way to boost your nutrient levels.”

Tom Amery, managing director of The Watercress Company says, “Watercress is nature's immune-boosting powerhouse. Incorporating just one portion to your diet once a week will be a delicious step towards supporting your health and resilience.” 

Whether a handful of watercress is added to your meal, to soups, sandwiches or blitzed up into pesto, this versatile green is easy to incorporate into your family's meal.

To kick start your Winter Watercress Challenge, simply grab one bag of fresh watercress a week from your local supermarket, or from The Watercress Company: www.watercress.co.uk, and let the green superfood transform your winter wellness. 

Simple recipes to try:

Watercress Pesto 

40g Watercress

2 tbsp Olive oil

Handful of nuts – pine or hazelnut are good options

30g Hard cheese like Parmesan (plus extra for grating)

Salt

Add the watercress, oil, nuts, cheese and a generous pinch of salt to a blender and blitz until everything is combined. Loosen the mixture with the olive oil; add a little at a time until your desired consistency is reached. 

Watercress Soup with an Egg

Serves 2 | Prep time 10 mins Cook Time 20 mins

60g watercress

30g spinach

1 shallot, finely chopped

1 large potato, chopped small approx. 150g

50ml crème fraiche

2 eggs

In a pan, gently soften the shallot in a little oil before setting aside. 

In a pot, boil the chopped potato until soft. Add the watercress and spinach at the last moment, allow to cook for no more than a minute. Strain the mixture but reserve the cooking liquid. 

Add the shallot to the potato mixture and, using a hand blender, blitz everything together. Add the reserved cooking liquid a little at a time to thin it out to your desired texture. 

Stir though the crème fraiche and season to taste with salt and pepper. 

To serve, poach 2 eggs for 2-3 minutes in boiling water, until the whites are cooked but the yolk is runny. Serve the soup in 2 bowls and place an egg in each. 

Enjoy piping hot with crusty bread.
