Foods That Boost Immune System Health

In an era where maintaining good health is paramount, a robust immune system is absolutely essential. 

While lifestyle factors like exercise and sleep play a significant role, the food we consume can significantly enhance our immune defences. 

Here’s a look at some foods that can help bolster your immune system.

1. Citrus Fruits

Citrus fruits, such as oranges, lemons, limes, and grapefruits, are well-known for their high vitamin C content. Vitamin C is vital for the production of white blood cells, which are key to fighting infections. Given that the body does not produce or store vitamin C, daily intake is crucial for maintaining an effective immune system.

2. Red Bell Peppers

While citrus fruits are high in vitamin C, red bell peppers contain twice as much of this essential vitamin. They are also a rich source of beta carotene, which the body converts into vitamin A. Vitamin A is important for maintaining the health of your skin and mucous membranes, which are the body’s first line of defence against pathogens.

3. Broccoli

Broccoli is packed with vitamins A, C, and E, as well as fibre and many other antioxidants. It is one of the healthiest vegetables you can put on your plate. To retain its nutrients, it is best cooked as little as possible – or better yet, not at all.

4. Garlic

Garlic has been used for centuries for its medicinal properties. It contains compounds such as allicin, which is known to boost the disease-fighting response of some types of white blood cells in the body when they encounter viruses.

5. Ginger

Ginger is another ingredient many turn to after falling ill. It may help decrease inflammation, which can help reduce a sore throat and inflammatory illnesses. Ginger is also packed with antioxidants and has anti-inflammatory properties.

6. Spinach

Spinach made our list not just because it’s rich in vitamin C but also because it’s packed with numerous antioxidants and beta carotene, which may increase the infection-fighting ability of our immune systems. Like broccoli, spinach is healthiest when it’s cooked as little as possible so that it retains its nutrients.

7. Yoghurt

Yoghurt that contains live and active cultures, like Greek yoghurt, can stimulate your immune system to help fight diseases. Look for yoghurts that have "live and active cultures" printed on the label, and try to get plain yoghurts rather than the kind that are pre-flavoured and loaded with sugar.

8. Almonds

When it comes to preventing and fighting off colds, vitamin E tends to take a backseat to vitamin C. However, this powerful antioxidant is key to a healthy immune system. Nuts, such as almonds, are packed with the vitamin and also have healthy fats, which help in the absorption of fat-soluble vitamins.

9. Turmeric

Turmeric is a bright yellow, bitter spice that has been used for years as an anti-inflammatory in treating both osteoarthritis and rheumatoid arthritis. High concentrations of curcumin, which gives turmeric its distinctive colour, can help decrease exercise-induced muscle damage. Curcumin has promising immune-boosting potential.

10. Green Tea

Green tea is packed with flavonoids, a type of antioxidant. In studies, the amino acid L-theanine found in green tea may aid in the production of germ-fighting compounds in your T-cells. Additionally, green tea is a good source of the amino acid that enhances immune function.

Incorporating these foods into your diet can help enhance your immune system, but it's important to remember that no single food or supplement is a magic bullet. A balanced diet, combined with other healthy lifestyle habits, is the best way to support overall health and a strong immune system. Stay well, eat healthily, and keep your defences strong!

Fermentation Techniques You Can Use at Home

Fermentation, an ancient preservation method, has seen a resurgence in recent years due to its health benefits and culinary potential. 

By harnessing the power of natural microbes, you can transform basic ingredients into flavourful, nutritious foods and beverages. Here are some simple fermentation techniques you can try at home.

1. Vegetable Fermentation

One of the easiest and most rewarding fermentation projects is fermenting vegetables. The classic example is sauerkraut, but you can ferment almost any vegetable.

Ingredients:

Fresh vegetables (e.g., cabbage, carrots, cucumbers)

Sea salt or pickling salt

Water (if making a brine)

Steps:

Prepare the Vegetables: Clean and chop your chosen vegetables.

Salt the Vegetables: For dry salting, sprinkle salt directly onto the chopped vegetables and massage it in to draw out moisture. Alternatively, dissolve the salt in water to create a brine and submerge the vegetables.

Pack the Jar: Place the salted vegetables in a clean jar, pressing them down to release more juice and remove air bubbles.

Ferment: Cover the jar with a loose lid or cloth and leave it at room temperature. Check daily to ensure the vegetables remain submerged in the brine. Taste after a few days and continue fermenting until the desired flavour is achieved.

Store: Once fermented, seal the jar with a tight lid and store in the refrigerator.

2. Kombucha

Kombucha is a fermented tea known for its tangy taste and probiotic properties.

Ingredients:

Tea (black, green, or a blend)

Sugar

SCOBY (Symbiotic Culture of Bacteria and Yeast)

Starter tea (unflavoured kombucha from a previous batch or store-bought)

Steps:

Brew the Tea: Boil water and steep the tea, then dissolve sugar into the hot tea. Allow it to cool completely.

Combine: In a large glass jar, combine the cooled tea, SCOBY, and starter tea.

Ferment: Cover the jar with a cloth secured with a rubber band and let it ferment at room temperature for 7-14 days, depending on your taste preference.

Bottle and Second Fermentation: Remove the SCOBY, reserve some kombucha for the next batch, and bottle the rest. You can add fruit or herbs for flavour during this stage. Seal the bottles and leave them at room temperature for 2-3 days to carbonate before refrigerating.

3. Sourdough Bread

Sourdough bread, with its tangy flavour and chewy texture, is a favourite among home bakers.

Ingredients:

Flour (preferably strong bread flour)

Water

Salt

Sourdough starter (a mixture of flour and water colonised by wild yeast and bacteria)

Steps:

Maintain the Starter: Feed your starter regularly with equal parts flour and water. Ensure it is bubbly and active before baking.

Prepare the Dough: Mix the starter with more flour and water to create the dough. Let it rest, then add salt.

Bulk Fermentation: Allow the dough to ferment at room temperature for several hours, folding it periodically to develop gluten.

Shape and Proof: Shape the dough and let it proof (rise) until it’s ready to bake. This can take several hours or overnight in the fridge.

Bake: Preheat your oven with a baking stone or Dutch oven. Bake the bread until it has a deep, golden crust and sounds hollow when tapped.

4. Yoghurt

Homemade yoghurt is a simple and satisfying project that requires just milk and a yoghurt culture.

Ingredients:

Milk (whole, semi-skimmed, or skimmed)

Yoghurt culture (store-bought plain yoghurt or a commercial culture)

Steps:

Heat the Milk: Heat the milk to 82°C (180°F) to denature the proteins, then cool it to 43°C (110°F).

Inoculate: Stir in the yoghurt culture.

Incubate: Keep the mixture warm (around 43°C) for 4-12 hours. A thermos, yoghurt maker, or warm oven can help maintain the temperature.

Chill: Once the yoghurt has set, refrigerate it to thicken and develop flavour.

5. Fermented Beverages: Kvass and Ginger Beer

Kvass and ginger beer are traditional fermented drinks with unique flavours.

Kvass Ingredients:

Rye bread

Water

Sugar or honey

Yeast (optional)

Flavourings (e.g., raisins, mint)

Ginger Beer Ingredients:

Fresh ginger root

Sugar

Water

Lemon juice

Ginger beer plant (GBP) or a combination of yeast and lactobacillus

Steps:

Prepare the Base: For kvass, soak toasted rye bread in water, add sugar or honey, and yeast if using. For ginger beer, make a ginger syrup by boiling grated ginger with sugar and water, then cool and add lemon juice.

Ferment: Combine the base with GBP or yeast mixture. Allow it to ferment at room temperature for a few days.

Bottle and Carbonate: Strain and bottle the liquid. Leave at room temperature for 1-3 days to carbonate, then refrigerate.

Final Thoughts

Fermentation at home is a rewarding process that connects you with traditional methods of food preservation. It can be as simple or as complex as you like, and the results are not only delicious but also beneficial for your gut health. Happy fermenting!
