1. SEASONAL
CHANGES
OF FOOD
DR. SHRUTI BAID

2. Season is a division of the
year based on changes in
weather, ecology and the
number of daylight hours in a
given region.

3. Seasons are a result of the
axial parallelism of Earth’s
tilted orbit around the sun.
The tilt of 23.5 degree affects
the distribution of the sun’s
energy across the surface of
the planet

5. Seasonal changes in precipitation and temperature
affect soil, moisture, evaporation rates, river flow,
lake levels and snow cover.
These changes in vegetation affect the type and
amount of food available for humans and other
organism.

6. There are two definitions of
SEASONAL FOOD
GLOBAL SEASONALITY
Food that is outdoor grown or
produced during the natural
growing / production period for
the country or region where it is
produced. It need not necessarily
be consumed locally to where it is
produced.
LOCAL SEASONALITY
Food that is produced and
consumed in the same climatic
zone without high energy use
for climatic modification or
storage

7. • Spring, summer, monsoon, autumn,
late autumn and winter are the six
seasons of the year. Seasons are created
by the changing amount of sunlight as
the earth orbits the sun.
• Weather conditions in a country are
known as the climate. The climate
determines which foods can grow and
when.
• Seasonal foods are fruits and vegetables
that are ripe and ready in a particular
season. They will no longer grow when
the weather changes.

8. PERCEPTION OF SEASONAL FOOD
• Seasonal food is often associated with locally produced food, better
quality food or limited food choice and for some it is food associated
with annual cultural events
• Local and seasonal fruit and vegetables are often described as tastier,
fresher and better quality than the equivalent imported produce or
those produced out of season
• It is also often viewed as more expensive, less convenient, more time
consuming to source and limits the variety of food in the diet, which
would inhibit the purchase of only seasonal food
• Seasonal foods are sometimes associated with food items eaten at
specific times of the year linked to cultural events rather than the
natural growing or production seasons. Foods such as chocolate eggs
at Easter or turkey at Christmas that are abundant in shops only at
certain times of the year can give the perception of being seasonal
food.

9. As adaptations according to the changes is the key for survival, the knowledge of
regimen (RITUCHARYA) for various seasons is thus important.
People do not know or ignore the suitable types of food, dressing and other regimen to
be followed in particular season which leads to derangement of homeostasis and causes
various disease such as obesity, diabetes, hypertension etc.
Lifestyle disorder are a result of an inappropriate relationship of people with their
environment.

11. The year according to Ayurveda is
divided into two periods Ayana
(solstice) depending on the direction of
movement of sun that is Uttarayana
(northern solstice) and Dakshinayana
(southern solstice).
It is the form in which the nature expresses itself in a sequence in particular and
specific in present forms in short, the seasons. Each is formed of three Ritu

12. UTTARAYANA
Sun and wind are powerful
Sun takes away the strength of
the people and the cooling
quality of the Earth.
Increase in TIKTA(bitter),
KASHAYA(astringent),
KATU(pungent) rasa which
brings about dryness in the body
and reduces the bala(strength).
In modern science, it is seen on
21st June every year

13. DAKSHINAYANA
Moon is more powerful.
Unctuousness is set in the
atmosphere.
Increase in AMLA(sour),
LAVANA(salty),
MADHURA(sweet) rasa are
predominant.
Strength of the people enhances.
Winter solstice is seen on
21st December every year.

15. It has been said that the tridosha
theory in Ayurveda originated from
the theory of the three elements of the
universe. The names of these three
doshas, which are roughly equivalent
to humour, are
• vata (wind),
• pitta (bile), and
• Kapha (phlegm),
corresponding to the three elements
of the universe: air, fire, and water.
