I am no doctor, but from what I have read, having a strong immune system is one way to help your body fight the onslaught of the virus. The two aspects that keep coming up, related to having a strong immune systems are, your;
1. Intake of Vitamins which can boost the immune systems
2. Reduction of food that can cause Inflammation
From what I have read about the immune system, there are certain key Vitamins that play a part in both boosting the immune system and also reducing inflammations (which appears to be a downside to if you get the virus). They are as below
1.Consume Immune Boosting Vitamins
To support your immune system, you can eat immunity supporting foods like citrus fruits, garlic, broccoli, and spinach. If your immune system is already weak, it can also be helpful to supplement with key vitamins and minerals that may have become depleted, such as Vitamin D, Zinc, Vitamin C and Vitamin B. Most effective way to get high doses of Vitamin C, Vitamin B and Zinc is intravenously (IV).
In addition to the Vitamins, at good intake of PROBIOTICS, PROTEIN & WATER (to flush out toxins), is recommended
Key Vitamins to Boost the Immune System
• Vitamin D: Mainly from sunlight, but is also found in some foods such as eggs, fish, while some milks and margarine brands may be fortified with it.
• Zinc: Shellfish, oysters and other seafood, meat, chicken, lamb, dried beans and nuts.
• Vitamin C: Oranges, lemons, limes, berries, kiwifruit, broccoli, tomatoes and capsicum.
• B12: Animal products, including eggs, meat and dairy, and also in fortified soy milk - essential for the production of Hemoglobin which carries oxygen in the blood.
• Iron: meat, chicken and fish. Vegetarian sources include legumes, whole grains and iron-fortified breakfast cereals -- essential for the production of Hemoglobin which carries oxygen in the blood.
Other helpful Vitamins
Vitamin A: Oily fish, egg yolks, cheese, tofu, nuts, seeds, whole grains and legumes
Vitamin B6 (riboflavin): cereals, legumes, green leafy vegetables, fruit, nuts, fish, chicken and meat
Vitamin B9 (folate): green leafy vegetables, legumes, nuts and seeds and commercial bread-making flour
2.Reduce or stay away from Foods that cause Inflammation
Sugar, processed meat, vegetable oils, and alcohol tend to be inflammatory foods so they busy the immune system, leaving other problems in your body unaddressed. It is helpful to remove these inflammatory foods if we want a healthy immune system.
These three Vitamins (below) apparently help to control inflammation by mopping up the impact of oxidative stress produced, by free radicals that pierce cell walls causing the contents to leak.
• Vitamin C: Oranges, lemons, limes, berries, kiwifruit, broccoli, tomatoes and capsicum
• Vitamin E: Nuts, green leafy vegetables and vegetables oils.
• Selenium: Nuts, especially Brazil nuts and meat, cereals and mushrooms
Just my 2 cents worth
So from my point, I am eating,
A) An Orange very day and drinking a liter of Pineapple juice every day because it not only contains more Vitamin C, but also contains Zinc, Beta Carotene, Copper, and Folate. Topped up with some Kiwi fruit, for a good dose of Vitamin C every day
B) Broccoli every night, because it is a good source of Fibre & Protein and it also contains iron, potassium, calcium, selenium & magnesium, plus Vitamins A, C, E, K along with a good array of Vitamins B and folic acid.
C) Some Cheese & Vegemite on crackers every night, because Vegemite is one of the richest sources of Vitamin B, specifically B1 Thiamine, B2 Riboflavin, B3 Niacin and B9 Folate
D) Drasitically reduced my intake of any Sugar and now use Honey for my natural sweetener, Honey also contains vitamins such as Ascorbic acid, Pantothenic acid, B3 Nniacin, B2 Riboflavin and minerals such as Calcium, Copper, Iron, Magnesium, Manganese, Phosphorus, Potassium & Zinc
All just to give my immune system that better fighting chance.
Hope this helps

) is good or does no harm. The problem with the pineapple juice (Not pineapple fruit) is that the dietary fiber is gone and the sugar is quite high.
