2. Healthy diet
⢠A healthy diet involves consuming primarily
fruits, vegetables, and whole grains to satisfy
caloric requirements, provide the body with
essential nutrients, phytochemicals, and fibre,
and provide adequate water intake.
⢠A healthy diet supports energy needs and
provides for human nutrition without
exposure to toxicity or excessive weight gain
from consuming excessive amounts.
3. Dietary guidelines for lifestyle
modification-NIN
⢠Calories should be sufficient to maintain appropriate
body weight for a given height.
⢠Carbohydrate should constitute 55-65% of calories
with emphasis on complex carbohydrates.
⢠Proteins should provide around 10-15% of the total
calories.
⢠Total fat intake should be between 15-30% of total
calories.
⢠Cholesterol should not exceed 300mg/day in the
diet.
⢠Saturated fat should be less than 10% of the total
calories.
4. Unhealthy diet
â˘High fat
â˘High salt
â˘High sugar
â˘Carbohydrate
rich
â˘Less intake of
fibre
â˘Less intake of
vegetables and
fruits
5. High sugar diet
⢠Increased consumption
of refined carbohydrates
along with reduced fibre
intake may lead to type 2
diabetes.
⢠High GI diet unfavorably
affects CVD risk factors.

6. High salt diet
⢠Long term high salt diet
leads to hypertension
and renal injury.
Long-term high salt diet causes hypertension and alters renal cytokine gene expression profiles in
Sprague-Dawley rats. Gu JW, Young E, Pan ZJ, Tucker KB, Shparago M, Huang M, Bailey AP.

8. Fruit and vegetable consumption
⢠low fruit and vegetable intake
is estimated to cause about
31% of ischemic heart
disease and 11% of stroke
worldwide.
⢠Up to 2.7 million lives could
potentially be saved each
year if fruit and vegetable
consumption was sufficiently
increased

9. Healthy food options
⢠Increase consumption of fruits and vegetables
(400 gms), and legumes, whole grains and nuts
⢠Limit the intake of free sugars
⢠Limit energy intake from total fats and shift fat
consumption away from saturated fats to
unsaturated fats and towards the elimination
of trans-fatty acids
⢠Limit salt (sodium) consumption from all
sources and ensure that salt is iodized
