The immune system is the body’s baked-in line of defence against a host of different dangers. From infections to the flu, without our immune system keeping us safe, we wouldn’t last very long in a world packed with microorganisms out to cause us harm. This is why we must always do whatever we need to do to ensure that our immune systems are working at their peak, especially as we begin to get older and immune functions start to decline somewhat.
Fortunately, there is a wide range of natural foods that can boost the immune system quickly and without any side effects.
All Citrus Fruit
Citrus fruits are some of the best foods in the world that we can eat for a range of reasons, but one of the most important is the vitamin C that comes packed into every, single one. Vitamin C is a powerful vitamin that’s linked to important bodily processes, with one of them being the increased production of white blood cells, which are used by the immune system to attack any foreign bodies. Grapefruit, oranges, tangerines, and lemons are all great choices.
Heralded by many nutritionists as one of the healthiest things we can eat in the world, broccoli is a food that we should try and consume just about every day, if possible. Part of the family of cruciferous vegetables, broccoli contains vitamins A, C, E, along with plenty of fibre and antioxidants. Like any cruciferous veggie, cooking broccoli for too long can break down some of its most important compounds, so it’s best steamed, or if cooked for long periods of time, it should be covered in mustard seed powder.
Perhaps the most delicious addition to any dish, garlic is the world’s favourite flavour enhancer, but it also boasts powerful benefits to the immune system. Raw garlic is best, as it contains a compound called allicin, which research has shown can give our immune system a significant boost, especially when fighting flues and colds. With the current pandemic only now going through its second wave, doctors around the world are suggesting using garlic as a great natural supplement for immunity function. Garlic has been used for centuries in traditional medicine, and it’s only now that nutritional science is starting to break down what our ancestors have known forever.
Spinach is well-known as a food that’s good for us, but many might not realise just how healthful it really is. Spinach is cheap, it’s packed with antioxidant, beta carotene, and vitamin C, all of which have been proven to give our immune systems a boost when needed, as well as a kick in energy for punting the pigskin around. For those that love spinach and eat it every day, caution should be taken as it’s been shown to cause kidney stone when over-consumed. This is due to the oxalic acid that can be found in the leafy green, and while eating spinach every few days is recommended, daily consumption can lead to problems for anyone with kidney issues.
