Increasing your immunity is easier said than done. Still, you can make some dietary and lifestyle adjustments to help your body's defences work more effectively against viruses and other disease-causing organisms.

Most individuals know the value of maintaining a healthy routine that includes nutrient-dense food, regular exercise, and stress-relieving hobbies. However, taking care of ourselves has the added advantage of strengthening our immune systems to fend off illnesses like the flu and the common cold—or at the very least, to help our bodies battle illness when we do become unwell. This is in addition to being good for a healthy weight and clear skin and preventative for long-term health issues.

Our immune systems guard against bacteria, poisons, and viruses and shield us from the illnesses they bring on. Additionally, immune systems control how the body reacts to ordinarily harmless activity and assist in eliminating sick or contagious cells from our bodies.

There is no magic cure for preventing or combating sickness, but now is as good a moment as any to talk about natural strategies to maintain strong immune systems.

What are signs of a weak immune system?

Susceptibility to infection is the main sign of a compromised immune system. A person with a compromised immune system is more susceptible to infections than the average person, and these illnesses may be more severe or difficult to treat.

Additionally, these people might be battling with an infection that someone with a more robust immune system would not catch. People with a weakened immune system typically contract the following infections more severely and frequently:

• skin infections
• pneumonia
• meningitis
• bronchitis

Additionally, those who have weakened immune systems may be more susceptible to:

• autoimmune diseases 
• growth and developmental delays as children and newborns
• inflammation of the internal organs 
• anaemia 
• other blood illnesses or abnormalities
• gastrointestinal problems, such as appetite loss, diarrhoea, and stomach cramping

A doctor can perform a baseline blood test to determine whether a patient has a compromised immune system. If a person has antibodies within the usual range, the test will reveal that.

Which foods boost your immune system?

Providing your body with specific meals may assist in maintaining a robust immune system.

The first thing you should do while looking for strategies to avoid getting colds, the flu, or other infections is to go to your neighbourhood grocery store. Make sure to incorporate potent immune system boosters in your diet plans.

Fruits

One of the food groups with the highest nutritional density is fruit. Because they are rich in vitamins, minerals, and several physiologically active substances, they can significantly strengthen your immune system.

Vegetables

Increasing your intake of vegetables is one of the best strategies to strengthen your immune system. This food group offers a substantial number of vitamins, minerals, and phytonutrients, just like fruits. They are also an excellent source of fibre and prebiotics, which are substances that nourish the beneficial bacteria in our stomach.

Mushrooms

This food group contains significant amounts of selenium and B vitamins, both of which are crucial for the health of our immune system. Additionally, many highly specific immunomodulatory and anti-cancer proteins are present in mushrooms.

Fermented foods

The history of fermented food and drink is extensive. For many good reasons, they were among the earliest manufactured foods that people ate. Fermentation extends the shelf life, ensures food safety, and enhances the flavour of foods like yoghurt, pickles, sauerkraut, and kimchi. Additionally, it improves their nutritional qualities.

Seafood

Seafood like oily salmon is a fantastic source of melatonin, tryptophan, polyamines, and omega-3 fatty acids. Frequent fish consumption has been known to improve gut health and lower the risk of inflammatory diseases, including psoriasis and rheumatoid arthritis.

What supplements assist your immune system? 

You should search for supplements with the correct amounts of vitamin C, vitamin D, and/or zinc when looking for ones that help strengthen your immune system. Like the foods mentioned before, these vitamins and minerals will be the primary components supporting your immune system. Making sure these three are included in your diet can assist in somewhat enhancing your immunity because deficiencies of these three are significant contributors to a compromised immune system.

At the end of the day, you should ensure the food you consume is nutritious and take supplements such as multivitamins to promote a strong immune system and meet nutritional needs.

Recommendations

There isn't a single product that can replace getting enough sleep, drinking enough water, eating a lot of fruits and vegetables, or moving about moderately. Nevertheless, you can consume various vegetables, herbs, vitamins, and minerals to support a solid immune system foundation.

Always speak with your doctor before taking any action regarding your health. Supplements have a wide range of potential effects and it's important to ensure that they are right for you. This article is not intended to diagnose, treat, or cure any disease.
