3. INTRODUCTION
 Milk is a white liquid produced by the mammary glands of
mammals. All mammals, including humans, will normally produce
milk to feed their offspring until they are ready for solid food.
 It contains valuable nutrients, and it can offer a range of health
benefits. Calcium, for example, can prevent osteoporosis
 However, some people are not able to digest lactose, the sugar in
milk, after they are weaned, because they do not produce enough of
an enzyme known as lactase. Lactase is needed to digest milk
properly.
 As concerns about lactose intolerance and milk allergies widen, a
range of substitute milks, such as almond and soy milk, have
become available.

4. BENEFITS
 Milk is loaded with numerous essential nutrients.
 Good source of protein.
 Benefits bone health.
 Versatile ingredient in many food products.
 Source of calcium.

5. Lactose Intolerance
 Lactose intolerance is a digestive disorder caused
by the inability to digest lactose, the main
carbohydrate in dairy products
 Without enough lactase, a person will not be able
to digest dairy products that contain lactose.
 Symptoms include
- bloating - diarrhea
- stomach pain - Gas
- nausea

6. AROUND 65% OF THE WORLD’S POPULATION IS LACTOSE INTOLERANT

7.  Milk allergy: 2–3% of kids under the age of three are
allergic to cow’s milk. This can cause a range of
symptoms, including rashes, vomiting, diarrhea and
severe anaphylaxis. Around 80% of kids outgrow this
allergy by age 16.
 Overconsumption of potassium or phosphorus,
both of which exist in high levels in milk, can harm
those whose kidneys are not fully functional. If the
kidneys cannot remove excess potassium or
phosphorus from the blood, it could be fatal.
 Overconsumption of calcium is rare with food
intake alone, but it can cause unwanted side effects
such as constipation, kidney stones, or kidney failure.
This may be a risk when taking calcium supplements.

8.  Other health problems include Acne, Prostate cancer.

11. Effects on environment

12.  Air- Particulate matter and odor from on-farm
activities can negatively impact air quality.
 Water- Manure and fertilizer that runoff from dairy
farms can pollute water resources.
 Habitat- Currently over two-thirds of the world's
agricultural land is used for maintaining livestock,
including beef and dairy cows. One-third of the
world's land suffers desertification due, in large part,
to deforestation, overgrazing and poor agricultural
practices

13.  Soil erosion- Turning forests into pasture or feed crop
production areas, overgrazing.
 ANIMAL HEALTH AND WELFARE- Improper
handling of dairy cows decreases the productivity of
cows due to stress and ill health, and leads to
increased greenhouse gas emissions.

17. Conclusion
 The majority of reliable evidence suggests that dairy
can be an important nutrient-rich choice for a
healthful diet. However, it is up to each individual to
decide whether or not to consume it.
 People who do not or cannot consume dairy should
obtain calcium from milk, leafy green vegetables, and
other calcium-rich foods.
 People may wish to speak with a health professional
about their dietary needs based on their health history
and lifestyle.
