Svensk studie viser at melkedrikking øker risiko for å tø for tidlig og risiko for benbrudd

Sjekk kildene: Melk og kviser, og melkefritt kosthold i forebygging av akne (kviser)

Det er en link mellom melk og kviser, eller akne. Flere studier viser at en kosthold uten melk kan hjelpe mot kviser, altså forbedre symptomer på vanlig akne/ kviser (acne vulgaris) (1). Sammenheng mellom melk og kviser blir stadig bedre dokumentert. I the Harvard Nurses’s Study fant man en sammenheng mellom konsumet av meieriprodukter på ungdomsskole og akne-diagnose stilt av lege (2).

Melk, andre meieriprodukter og andre sykdommer

Meieriprodukter er ikke bare satt i sammenheng med akneepidemien (3) men også flere andre sykdommer i den vestlige verden, og her er det varierende mengde av vitenskapelige bevis. Det sterkeste evidensen (vitenskapelige bevis) finnes for at meieriprodukter bidrar til utvikling av kreft i prostata. Det er blant annet derfor det er slik at norske helsemyndigheter ikke gir kvantitative anbefalinger (bestemt mengde) for inntaket av meieriprodukter.

Hvorfor melk forårsaker kviser: Naturige steriode kjønnshormoner i kumelk

Noen studier tyder på at skummet melk kan være lite gunstig for tenåringer på grunn av kumelkens naturlige innhold av steroide kjønnshormoner (4). Dette gjelder særlig skummet melk (5). Disse hormonene finnes også i økologisk melk (6) og er ikke bare satt i sammenheng, men kan også medvirke utviklingen av brystkreft og prostatakreft (7).
Noen spekulerer om hormonene som finnes i meieriprodukter kan forklare hvorfor kvinner som har et vanlig vestlig kosthold har en fem ganger høyere sjanse for fødsel av tvillinger enn kvinner som spiser plantebasert (8).

Nesten all kumelk kommer fra drektige kyr

Forklaringen for det høye innholdet av steroide kjønnshormoner i kumelken er at kumelk nesten alltid kommer fra drektige kyr, som har høye nivåer av disse hormonene i blodsirkulasjonen og derfor også i sin melk.

Although the total number of studies conducted within the past 40 years is relatively small, the growing body of epidemiologic and experimental evidence suggests a relationship between diet and acne.
(Burris J, Rietkerk W, Woolf K. Acne: the role of medical nutrition therapy. J Acad Nutr Diet. 2013 Mar;113(3):416-30. doi: 10.1016/j.jand.2012.11.016. Review. PubMed PMID: 23438493. http://www.ncbi.nlm.nih.gov/pubmed/23438493)
This study suggests that diet, particularly dietary GI, saturated fat, trans fat, milk, and fish may influence or aggravate acne development. Future research is necessary to elucidate the proposed mechanisms linking diet and acne and determine the impact of medical nutrition therapy on acne Development.

CONCLUSION:
We found a positive association between intake of skim milk and acne. This finding suggests that skim milk contains hormonal constituents, or factors that influence endogenous hormones, in sufficient quantities to have biological effects in consumers.
We found a positive association between intake of milk and acne. This finding supports earlier studies and suggests that the metabolic effects of milk are sufficient to elicit biological responses in consumers.
Both, restriction of milk consumption or generation of less insulinotropic milk will have an enormous impact on the prevention of epidemic western diseases like obesity, diabetes mellitus, cancer, neurodegenerative diseases and acne.

The milk-induced change of the IGF-1-axis most likely contributes to the development of fetal macrosomia, induction of atopy, accelerated linear growth, atherosclerosis, carcinogenesis and neurodegenerative diseases. Observations of molecular biology are supported by epidemiologic data and unmask milk consumption as a promoter of chronic diseases of Western societies.

A high intake of dairy protein was associated with an increased risk, with a hazard ratio for the top versus the bottom fifth of intake of 1.22 (95% confidence interval (CI): 1.07–1.41, Ptrend=0.02). After calibration to allow for measurement error, we estimated that a 35-g day−1 increase in consumption of dairy protein was associated with an increase in the risk of prostate cancer of 32% (95% CI: 1–72%, Ptrend=0.04). Calcium from dairy products was also positively associated with risk, but not calcium from other foods. The results support the hypothesis that a high intake of protein or calcium from dairy products may increase the risk for prostate cancer.
The introduction of exogenous hormones and growth factors into tissues that have not evolved defensive feedback inhibition of their corresponding endogenous sources is postulated as a direct stimulatory threat to these organ systems, whether for hyperplasia or neoplasia.
Basing on a revision of existing published data, it could be concluded that maximum daily intakes for hormones are not reached through milk ingestion. Although dairy products are an important source of hormones, other products of animal origin must be considered as well for intake calculations.
