
Immunity is the ability of the body to defend itself against
disease-causing organisms. Everyday our body comes in
contact with several pathogens, but only a few results into
diseases. The reason is, our body has the ability to release
antibodies against these pathogens and protects the body
against diseases. This defence mechanism is called Immunity.
There are two major types of immunity:
 Innate Immunity or Natural or Non-specific
Immunity.
 Acquired Immunity or Adaptive Immunity.
This type of immunity is present in an organism by
birth.
 This is activated immediately when the pathogen
attacks. Innate immunity includes certain barriers
and defence mechanisms that keep foreign particles
out of the body.
 Innate immunity refers to the body’s defence
system.
 This immunity helps us by providing the natural
resistance components including salivary enzymes,
natural killer cells, intact skin and neutrophils, etc.
which produce an initial response against the
infections at birth prior to exposure to a pathogen
or antigens.
 It is a long-term immunity in which our body
produces the antibodies on its own.




Acquired immunity or adaptive immunity is the
immunity that our body acquires or gains over time.
Unlike the innate immunity, this is not present by birth.
The ability of the immune system to adapt itself to
disease and to generate pathogen-specific immunity is
termed as acquired immunity. It is also known as
adaptive immunity.
The immune system of our body identifies the pathogens
which have encountered in the past. It is mainly caused
when a person comes in contact with the pathogen or its
antigen.
Our body starts producing antibodies to engulf the
pathogen and destroy its antigen.
 Almonds
are one of the richest source of
Vitamin and Healthy Fats.
Amla is loaded with nutrients and vitamins.
 It is the richest source of Vitamin C as it contains 20
Times more Vitamin C than Oranges .


Broccoli is supercharged with vitamins and
minerals. Packed with vitamins A, C, and E, as well
as fiber and many other antioxidants.
 Blueberries
are filled with antioxidants that
can help treat and prevent coughs and colds.



Garlic is one of the fighters in fighting infections.
It slows down hardening of arteries .
It’s immune boosting property is there as it has heavy
concentration of Sulphur containing compounds , such
as allicin.


Both green and black teas are packed with flavonoids, a
type of antioxidant. Where green tea really excels is in its
levels of EGCG , another powerful antioxidant.
Green tea is also a good source of the amino acid Ltheanine. L-theanine may aid in the production of germfighting compounds in your T cells.

Kiwis are naturally full of a ton of essential
nutrients, including folate, potassium, vitamin K,
and vitamin C.
Mushrooms increase the number and strength of
immunity – boosting T- cells.
 It also act as a anti – inflammatory agent.

Papaya is another fruit loaded with vitamin C.
 It also have a digestive enzyme called papain that
has anti-inflammatory effects.


Spinach is not just rich in vitamin C but it’s also
packed with numerous antioxidents and BETA
CAROTENE which increase the infection fighting
ability of our immune system.
sweet potato has a great value of vitamin A and
vitamin C.
 Sweet potatoes are a cholesterol-free and fat-free food.
 Sweet potatoes serve up a healthy portion of fiber too.

 Tomatoes
are a great food to eat when you're
sick due to their high concentration of vitamin
C.

Turmeric is an anti-inflammatory in treating
both osteoarthritis and rheumatoid arthritis.

Watermelon has potassium, vitamin A, vitamin C
and vitamin B6. Calories in watermelon aren't
much at all.
Yogurt is a great source of vitamin D.
 It is live and active culture which stimulates our
immune system to help fight diseases.
