The calcium in milk is not readily absorbed by the human body.
Milk contains powerful (natural) hormones that increase body weight and interfere with women's own natural hormones.
Milk exacerbates allergies, asthma and a host of other illnesses.
I did extensive research before giving up dairy.
You can easily get more than enough calcium from Kale, quinoa, sesame seeds, amaranth, spinach and nuts. Calcium will be more readily absorbed in a natural state with the presence and aid of magnesium.
Milk as a food is junk food. Ultra pasteurization destroys what little benefits milk has. Hormones and chemicals (pesticides and antibiotics) negate any goodness in milk.
I suffered from severe seasonal allergies from early teens into my thirties. I gave up dairy and the allergies went away.
If you choose to consume it make sure it is organic and don't believe industry sponsored research and advertising. Milk does not help prevent osteoporosis. In fact, in countries with large dairy consumption the instance of osteoporosis is extremely high. In countries that do not rely on dairy the instance of osteoporosis is very low. The growing trend is go nn-dairy in this country. I receive up to 30 emails a day from chefs in the US and Canada seeking non-dairy recipes and vegan recipes. As a member of a 5,000+ organization of chefs we regularly correspond and the consensus is that the public at large wants to eat healthier and wants to reduce or eliminate dairy.
I use to say I would never give up dairy, but it was a lot easier than you think. I have never felt better in my life. My sinuses are clear, I never get colds or flu, my bp is in check and I dropped 35 lbs. after eliminating dairy.
One of the hottest chefs around, Louis Lanza, cooks non-dairy and is launching a chain of good fast foods with traditional and non-traditional fare.
As a chef, reliance on dairy such as cream and butter usually (not always) means the underlying ingredient (meat, fish, or vegetable) needs to be masked. Restaurants who do not buy the highest quality ingredients will drench the product with a heavy cream or butter sauce to hide this fact.
I am a big proponent of letting the natural food shine on its own without a lot of adornment.
Here are some examples:
Oven roasted cod filet drizzled with basil oil and fleur de sel.
Steamed asparagus with a lemon dill vinaigrette
Puree of celery root and parsnip with olive oil and white pepper
Fresh steamed spinach with sauteed mushrooms rolled up in spelt lasagna noodles in a rustic tomato sauce.
Salmon in paper with fresh herbs and lemon juice
Tofu marsala with caramelized onions
Pan seared breast of chicken (organic free range) with saffron tomato broth and basmati rice
Seared sea scallops with a crust of pistachio and thyme
Vegetarian Shepherd's Pie
Hand mashed Yukon gold potatoes with sea salt and white pepper
These meals are requested again and again without a speck of dairy. More research needs to be done independent of the dairy industry. There is evidence of milk affecting diabetes in children, autism, add, and asthma. There is even more evidence of milk causing or exacerbating ear infections and respiratory illnesses.
Unless you have a soy sensitivity then soy milk is a healthier and tastier way to go.
just my informed opinion.
