A glass of milk a day may assist hold bowel most cancers away – or so finds a research by Oxford College and Most cancers Analysis UK. The analysis means that rising each day milk consumption by as little as one glass may have a big impression on decreasing the probability of growing bowel most cancers.
There are almost 45,000 circumstances of bowel most cancers yearly within the UK, making it the nation’s fourth most typical most cancers – and third worldwide – however many of those are preventable.
In keeping with Most cancers Analysis UK information, 54 p.c of all bowel cancers may very well be prevented by having a more healthy way of life. Smoking, lack of train, alcohol, consuming processed meat, and poor food plan are all important elements within the growth of bowel most cancers.
As an oncologist, I counsel my sufferers about how food plan and way of life can affect well being, together with the threat of growing most cancers. However this analysis – one of many largest research into food plan and illness to date – has shed new gentle on how simple, low cost food plan modifications may help everybody to scale back their most cancers threat.
For instance, in addition to consuming an additional glass of milk per day, lowering consumption of alcohol and purple and processed meat may additionally assist shield in opposition to most cancers.
The research discovered that consuming a further 20 grams of alcohol a day, equal to a big glass of wine, elevated bowel most cancers threat by 15 p.c. Consuming greater than 30 grams of purple and processed meat each day was linked to an 8 p.c enhance in bowel most cancers threat.
Researchers took a novel, two-pronged strategy to look at the affiliation between milk consumption and bowel most cancers threat. First, they analysed genetic information from over 542,000 girls and centered on variants – tiny modifications in DNA – related to lactase persistence, the capacity to digest lactose in maturity.
Second, the workforce collected detailed dietary info from members, together with their each day milk consumption. By combining these two information units, the researchers have been capable of higher estimate the causal impact of milk consumption on bowel most cancers threat.
Hanging outcomes
The evaluation revealed that members who consumed a further 244 grams of milk per day – roughly equal to 1 massive glass containing 300 milligrams of calcium – had a 17 p.c decrease threat of growing bowel most cancers. This discount in threat utilized to varied forms of milk, together with entire, semi-skimmed and skimmed.
Researchers discovered that the protecting impact of milk consumption was impartial of different dietary elements and way of life habits. This implies that the advantages of milk in lowering bowel most cancers threat usually are not as a result of milk replaces unhealthy meals decisions or is consumed as a part of an total more healthy way of life.
The explanation why milk consumption could scale back bowel most cancers threat usually are not totally understood, however the researchers suggest a number of potential explanations.
First, milk is a wealthy supply of calcium, which has been linked beforehand to a lowered threat of bowel most cancers. Calcium could assist shield in opposition to most cancers by binding to probably dangerous substances within the intestine and selling the demise of irregular cells.
Subsequent, many milk merchandise are fortified with vitamin D, which has been proven to have anti-cancer properties and will assist regulate cell progress and division. Additionally, the lactose in milk can promote the expansion of helpful intestine micro organism that produce butyrate, a short-chain fatty acid with anti-inflammatory and anti-cancer results.
Lastly, milk incorporates conjugated linoleic acid, a fatty acid present in meat and dairy merchandise, which, in keeping with a 2021 labratory research, may even have anti-cancer properties.

Crucially, milk consumption will not be appropriate or helpful for everybody. These with lactose intolerance, milk allergic reactions, or different dietary restrictions ought to seek the advice of with healthcare professionals earlier than making important modifications to their dairy consumption.
General, this groundbreaking analysis supplies compelling proof for the potential function of milk consumption in lowering bowel most cancers threat. The discovering {that a} comparatively modest enhance in each day milk consumption may result in a big discount in bowel most cancers threat is especially encouraging. It means that small, achievable modifications in food plan may have significant impacts on public well being.
As we proceed to unravel the advanced relationships between food plan and illness, research like this one present invaluable insights that may inform each particular person well being decisions and broader public well being methods.
The potential for a easy dietary change to have such a big impression on most cancers threat underscores the significance of continued analysis on this area and highlights the ability of vitamin in shaping our well being.
