questions and answers
Questions and Answers

Can lactose intolerance be dangerous?

- there can be severe cases where you have to get intestinal surgery.

who does lactose intolerance mostly affect?

- it mostly affects infants and adults.

how can one strengthen the body without the calcium in milk?

-you can take vitamin supplements once a day and milk without lactate.


Decreasing or removing milk products from the diet usually improves the symptoms.

Most people with low lactase levels can drink 2 - 4 ounces of milk at one time (up to one-half cup) without having symptoms. Larger (more than 8 oz.) servings may cause problems for people with lactase deficiency.


Buttermilk and cheeses (they have less lactose than milk)

Fermented milk products, such as yogurt

Goat's milk (but drink it with meals, and make sure it is supplemented with essential amino acids and vitamins if you give it to children)

Ice cream, milkshakes, and aged or hard cheeses

Lactose-free milk and milk products

Lactase-treated cow's milk for older children and adults

Soy formulas for infants younger than 2 years

Soy or rice milk for toddlers

long term health consequences
Long Term Health Consequences

The important long-term health consequence of lactose intolerance is calcium deficiency that can lead to osteoporosis.

Less commonly, vitamin D deficiency may occur and compound the bone disease.

Both can be prevented easily by calcium and vitamin D supplements


Lactose intolerance is more common in people with Asian, African, Native American, or Mediterranean ancestry than it is among northern and western Europeans.

Causes of lactose intolerance include:

Bowel surgery

Infections in the small intestine from viruses or bacteria, which may damage the cells lining the intestine (most often in children)

Intestinal diseases such as celiac sprue

There is no way to prevent lactose intolerance.

It is harder for one that is lactose intolerant to get enough protein their body need


summary thank goodness its done
Summary!!! (thank goodness its done!)

Lactose Intolerance has many levels of severity.

An easy way to treat it is just not to eat food with lactate in it.

It appears hours or days after consumption.

Common symptoms include: Irritable bowel syndrome Joint problems Migraines Muscle and joint pain Depression and anxiety Fatigue Nausea and vomiting Ulcers and hyperactivity in children
