The Claim
In a large prospective cohort of over 182,000 UK adults followed for up to 13 years, higher dietary magnesium intake was significantly associated with a lower risk of developing Crohn's disease, ulcerative colitis, irritable bowel syndrome, and diverticular disease. Compared to the lowest intake group, those with the highest magnesium intake had hazard ratios of 0.495 for Crohn's disease, 0.632 for ulcerative colitis, 0.786 for irritable bowel syndrome, and 0.799 for diverticular disease, with reduced risk observed for intakes between approximately 334.7 and 420.0 mg per day.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
A large study of British adults found that people who eat more magnesium are less likely to develop several digestive problems like Crohn's disease, ulcerative colitis, irritable bowel syndrome, and diverticular disease. The benefit was seen when magnesium intake was around 335-420 mg per day.
See the scientific wording
In a large prospective cohort of over 182,000 UK adults followed for up to 13 years, higher dietary magnesium intake was significantly associated with a lower risk of developing Crohn's disease, ulcerative colitis, irritable bowel syndrome, and diverticular disease. Compared to the lowest intake group, those with the highest magnesium intake had hazard ratios of 0.495 for Crohn's disease, 0.632 for ulcerative colitis, 0.786 for irritable bowel syndrome, and 0.799 for diverticular disease. The reduced risk was observed for intakes between approximately 334.7 and 420.0 mg per day, suggesting an optimal range for gut health.
As people get older, their gut cells lose the ability to take in magnesium from food. Without enough magnesium, the proteins that hold gut cells together stop working properly, so the gut lining gets weak and leaky. This lets bacteria and other irritants get through the lining, which causes inflammation and leads to gut diseases like Crohn's disease, colitis, IBS, and diverticulitis. Eating enough magnesium keeps the gut lining strong and prevents this damage.
What the research says
1 studyStudy: Magnesium Deficiency Accelerates Gut Aging and Increases Susceptibility to Colitis
The study found that people who ate more magnesium had lower chances of getting Crohn's disease, colitis, IBS, and diverticulitis, so the claim is correct.
