What does this mean for cancer prevention?
Similarly, there’s no evidence that consuming a certain level of glutamine in your diet can help prevent cancer.
General advice to maintain good health is to eat a
well-balanced dietconsisting mainly of fresh fruits and vegetables, lean proteins, whole grains, legumes, and nuts.
Other frequently asked questions
Does glutamine cause cancer?
Cancer is complex. But glutamine doesn’t cause it.
Many types of cancer cells do appear to
use glutamine to grow and spread. But cancer itself is caused by genetic changes that then affect how cells grow and divide.
This can be due to DNA damage from harmful environmental factors, like UV rays or
cigarette smoke, or inherited from your parents.
Is there anything you can do to block or reduce glutamine naturally?
Glutamine is the most abundant
amino acid in the bloodstream. Plus, your body produces it by itself in addition to getting it from your diet.
So, there are no realistic ways of reducing glutamine levels through the likes of dietary changes.
Is glutamine in food?
Glutamine is found in
a range of foods.
Food with a
high protein contenttends to have the most amount of glutamine — think meat and other animal products like milk and cheese.
But you’ll find glutamine in anything containing protein, including the likes of white rice, cabbage, and raw spinach.
Are there certain foods you should avoid to reduce your risk of cancer?
“It’s been known for some time that dietary modifications — in particular, reduced consumption of red and processed meat, fast food, sugar, and alcohol, shifting toward regimens rich in fruits, vegetables, and whole grains — is associated with reduced cancer risk, regardless of other confounding risk factors,” explains Ulm.
It’s still unclear where glutamine falls into this.
Some research indicates that “higher blood glutamine levels may actually be protective against some disorders, such as cardiovascular disease, and that glutamine supplementation may paradoxically inhibit tumor growth and metabolic processes,” says Ulm.
But there are still no firm conclusions or specific recommendations.
So, sticking to a well-balanced diet rich in plant-based foods is the
best advice available.
Are there certain foods you should avoid if you’ve been diagnosed with cancer?
Again, there’s no evidence to suggest you should avoid foods containing glutamine if you have cancer — mainly because the body is likely to produce enough by itself and because glutamine is needed as it plays numerous important roles.
Having cancer
can affect your appetite and the way your body deals with nutrients. So, trying to eat as well as possible may help your body cope with both the disease and any treatments.
This usually means consuming a balanced diet and upping your protein and calorie intake if you lose weight. Your doctor may actually advise having more calorific snacks and swapping to high fat options.
They may also recommend steering clear of certain food and drink that can impact the side effects of treatment. This can include spicy foods, raw meat or seafood, and alcohol.
