Dairy and Obesity

Dairy and Obesity Stomachaches are only the beginning of the problems that your kids may face if you give them dairy products. Studies suggest that milk consumption may contribute to asthma, constipation, recurrent ear infections, iron deficiency, anemia, and even cancer.

Consuming dairy products can also make kids overweight. There is a reason why dairy products are so fattening—they're packed with fat and calories. In fact, calves can gain almost 500 pounds by the time they are weaned from their mothers. The calories from the fat and sugar in cow's milk will add to your child's waistline and detract from his or her health.

On the other hand, many plant foods contain calcium but don't have all the cholesterol or come with the adverse health effects that are associated with dairy products. Plus, despite what the powerful dairy industry lobby might claim, independent scientists have found that the calcium in plant-based sources is more easily absorbed by human bodies than is the calcium in cow's milk.

In fact, drinking milk may actually weaken our bones! Ironically, American women have one of the highest rates of dairy consumption in the world, yet they also suffer from the highest rates of osteoporosis.

A study funded by the National Dairy Council found that women who drank three glasses of milk a day for two years actually lost bone mass at twice the rate of women who did not drink milk. Furthermore, the Harvard Nurses' Health Study confirmed that women who received the majority of their calcium from dairy foods also suffered more broken bones than women who did not drink milk. Research has clearly shown that children should avoid milk and should fill up on calcium-rich plant foods to build strong bones.

Numerous studies have also shown a link between milk consumption and the development of various types of cancer. For example, a major study of nearly 5,000 children found that a high intake of dairy products was associated with nearly triple the colon cancer rate of children with a low intake of dairy products.

Susu dan Obesitas perut hanya awal dari masalah yang anak-anak Anda mungkin menghadapi jika Anda memberi mereka produk susu. Penelitian menunjukkan bahwa konsumsi susu dapat menyebabkan asma, sembelit, infeksi telinga berulang, defisiensi besi, anemia, dan bahkan kanker.
Mengkonsumsi produk susu juga bisa membuat anak kelebihan berat badan. Ada alasan mengapa produk susu sangat penggemukan-mereka dikemas dengan lemak dan kalori. Bahkan, betis bisa mendapatkan hampir 500 pounds di waktu mereka disapih dari ibu mereka. Kalori dari lemak dan gula dalam susu sapi akan menambah ukuran pinggang anak Anda dan mengurangi nya atau kesehatannya.
Di sisi lain, makanan nabati banyak mengandung kalsium tetapi tidak memiliki semua kolesterol atau datang dengan efek yang merugikan kesehatan yang berhubungan dengan produk susu. Plus, meskipun apa lobi kuat industri susu mungkin mengklaim, para ilmuwan independen telah menemukan bahwa kalsium dalam nabati sumber lebih mudah diserap oleh tubuh manusia daripada kalsium dalam susu sapi.
Bahkan, minum susu sebenarnya dapat melemahkan tulang kita! Ironisnya, wanita Amerika memiliki salah satu tingkat tertinggi konsumsi susu di dunia, namun mereka juga menderita dari tingkat tertinggi osteoporosis.
Sebuah studi yang didanai oleh Dewan Susu Nasional menemukan bahwa wanita yang minum tiga gelas susu sehari selama dua tahun benar-benar kehilangan massa tulang dua kali lipat tingkat perempuan yang tidak minum susu. Selanjutnya, Studi Kesehatan Perawat Harvard menegaskan bahwa wanita yang menerima sebagian besar kalsium dari makanan susu juga menderita patah tulang lebih daripada wanita yang tidak minum susu. Penelitian telah jelas menunjukkan bahwa anak harus menghindari susu dan harus mengisi pada makanan yang kaya kalsium tanaman untuk membangun tulang yang kuat.
Sejumlah penelitian juga telah menunjukkan hubungan antara konsumsi susu dan pengembangan berbagai jenis kanker. Sebagai contoh, sebuah studi besar dari hampir 5.000 anak menemukan bahwa asupan tinggi produk susu dikaitkan dengan hampir tiga kali lipat tingkat kanker usus besar anak-anak dengan asupan rendah dari produk susu.

Abstract
BACKGROUND:

Dairy consumption affects biological pathways

associated with carcinogenesis. Evidence for a

link between cancer risk and dairy consumption

in adulthood is increasing, but associations

with childhood dairy consumption have not

been studied adequately.
OBJECTIVE:

We investigated whether dairy consumption in

childhood is associated with cancer incidence

and mortality in adulthood.
DESIGN:

From 1937 through 1939, some 4,999

children living in England and Scotland

participated in a study of family food

consumption, assessed from 7-d household

food inventories. The National Health Service

central register was used to ascertain cancer

registrations and deaths between 1948 and

2005 in the 4,383 traced cohort members.

Per capita household intake estimates for

dairy products and calcium were used as proxy

for individual intake.
RESULTS:

During the follow-up period, 770 cancer

registrations or cancer deaths occurred. High

childhood total dairy intake was associated

with a near-tripling in the odds of colorectal

cancer [multivariate odds ratio: 2.90 (95%

CI: 1.26, 6.65); 2-sided P for trend =

0.005] compared with low intake, independent

of meat, fruit, and vegetable intakes and

socioeconomic indicators. Milk intake showed a

similar association with colorectal cancer risk.

High milk intake was weakly inversely

associated with prostate cancer risk (P for

trend = 0.11). Childhood dairy intake was not

associated with breast and stomach cancer

risk; a positive association with lung cancer

risk was confounded by smoking behavior

during adulthood.
CONCLUSIONS:

A family diet rich in dairy products during

childhood is associated with a greater risk of

colorectal cancer in adulthood. Confirmation of

possible underlying biological mechanisms is

needed.
