About the ingredients
The foods we used in recipes above have several essential nutrients for the immune system to work well. These include proteins, vitamins A, C, E, B-6, zinc, selenium, iron, copper, folic acid and water.
Here’s some specific info on each of these substances.
To note: food nutritional data are from FoodData Central.
Proteins
They’re essential for disease prevention. We need them for the immune system to function properly.
In general, many experts recommend a daily intake of 0.8 g of protein per kg of body weight for adults. For example, someone weighing 80 kg would consume 64 g of protein per day. Some people, such as athletes, may need higher doses.
These substances are usually found in some plant foods, such as soybeans, and in several animal products, such as meat and eggs.
Some foods (such as bananas or broccoli) also include these nutrients, but to a lesser extent.
Folate
It’s a key substance to synthesize proteins. Therefore, it may help boost the immune system.
Specialists recommend a daily folate intake of 400 mcg for adults.
Finally, green leafy vegetables are particularly rich in this nutrient.
Water
Nutrients are essential for the immune system and overall health. And we need to keep the body hydrated to transport nutrients through the blood to the organs.
Also, water is important for body cleansing. That is, it helps to eliminate foreign invaders and wastes.
Experts from the National Academies of Sciences, Engineering and Medicine recommend a daily water intake of 2.7 l for women and 3.7 l for men. These values include water from food.
In general, the ingredients we used in the juices above include high percentages of water (>80% of total weight).
Vitamin C
According to research, this substance contributes to immune defense by supporting various cellular functions. Among its properties, it’s worth highlighting the following:
- It supports the epithelial barrier function against pathogens and works as an antioxidant. That is, it helps protect against environmental oxidative stress.
- Also, it builds up in the cells and may promote the destruction of microbes.
On the other hand, according to experts from the National Institutes of Health (NIH), the recommended daily intake of vitamin C for people 19 years old is 75 mg for women and 90 mg for men. For smokers, higher doses are recommended.
Finally, papaya, broccoli, pineapple, kiwi, parsley and citrus fruits are some examples of foods particularly rich in this nutrient.
Zinc
Some plant foods, such as flax / chia seeds, broccoli, cucumber or parsley, contain this nutrient. However, animal products, such as eggs or meat, usually include a higher quantity.
According to a study published in 2017, both deficiency and excess of zinc may cause serious disturbances of immune function. Therefore, it’s important to maintain healthy levels of this substance.
In general, the recommended daily intake of zinc for adults is 11 mg for men and 8 mg for women.
Selenium
According to a study conducted in 2019, deficiency of this compound may be associated with the possibility of contracting viruses.
The NIH recommends a daily selenium intake of 55 mcg for those over 14 years of age.
Finally, broccoli, chia / flax seeds and bananas are examples of plant foods with this nutrient.
Iron
This is a key component of the immune response. However, according to research, both too much and too little of it may increase susceptibility to infections.
In general, the recommended daily intake of iron varies depending on gender, age, pregnancy and lactation. Below, you can see these values for people over 19 years old, according to a book from the Institute of Medicine (United States).
- Women: 18 mg for those over 19 years of age, 8 mg for those over 51 years of age, 27 mg for pregnant women and 9 mg for lactating women between 19 and 50 years of age.
- Men: 8 mg for those over 19 years of age.
On the other hand, green leafy vegetables, such as parsley, are rich sources of this nutrient.
Vitamin A
According to research, this substance is key to help reduce inflammation and improve defenses against various infectious diseases. Among its functions, it protects the body’s tissues and mucous.
Experts recommend that those over 14 years of age consume 900 mcg of vitamin A if they’re male, or 700 mcg if they’re female.
Finally, parsley, broccoli and spinach, along with orange and yellow fruits, are excellent sources of this nutrient.
Vitamin B-6
Bananas are especially rich in this substance.
According to a study, a deficiency of this nutrient could reduce white blood cells and negatively affect the immune system.
On the other hand, the recommended daily intake of this vitamin varies between 1.3 mg and 1.7 mg for adults over 19 years of age.
Copper
According to research, adequate copper levels are associated with a well-functioning immune system.
On the other hand, for adults over 19 years of age, it’s recommended a daily intake of 0.9 mg of copper.
In general, there’re several green leafy vegetables, seeds and fruits containing significant quantities of this nutrient.
Pregnancy and lactation, greater needs
In these cases, the daily nutritional needs of the substances mentioned above may be higher, except for iron. Above you can see the recommendations for this nutrient.
Are these juices useful to increase white blood cells?
