Blue cheese is a type of polarizing meals that you just both love or hate, like cilantro or Hawaiian pizza. When you’re within the “hate it” camp, this text won’t be for you. However should you’re an enormous fan, we’ve obtained excellent news!
In response to a latest examine revealed in Nature Cell Biology, this pungent unfold is perhaps more healthy for you than beforehand thought resulting from one naturally occurring compound present in blue cheese1. Researchers have linked the polyamine spermidine to autophagy enhancement (primarily the regrowth of cells!) and decreased incidence of cardiovascular and neurodegenerative ailments — and blue cheese is positively loaded with it.
What Is Spermidine?
Spermidine is a polyamine identified for its hyperlink to longevity, although we’re solely simply beginning to perceive the mechanisms by which it really works in mammals. For Dr. Pete Sulack, founding father of The Be Resilient Program, spermidine’s energy lies in its skill to advertise autophagy, the physique’s pure means of mobile regeneration.
And that’s not all. Dr. Sulack additionally says that spermidine has additionally been proven to enhance mitochondrial perform, cut back irritation, assist immune protection, and even prolong lifespan. He goes as far as to characterize spermidine as “probably the most promising longevity compounds in meals.”

The Analysis Behind Spermidine Advantages
The analysis helps these claims. A 2017 examine discovered that spermidine may cut back the danger of liver fibrosis and cancerous liver tumors2. A 2021 analysis evaluation in Getting old and Illness revealed that spermidine may show promising in treating age-related neurodegenerative, metabolic, musculoskeletal, and immune ailments3, and a 2023 examine in Scientific Experiences discovered that spermidine may cut back age-related angiogenic decline4.
However Lena Bakovic, MS, RDN, CNSC at Vnutrition, is a little more cautious together with her reward of the polyamine. “Spermidine has been studied for anti-aging properties and in offering advantages to mobile well being, in flip as a result of it could assist to assist autophagy (our our bodies’ means of destroying broken cells),” she says. “Nonetheless, to date, these results have solely been demonstrated in restricted and fairly weak scientific analysis. Extra analysis is certainly required in serving to to substantiate the potential well being advantages of spermidine.”
Certainly, earlier research have had issue displaying how we will take full benefit of those pure advantages of spermidine. A 2022 randomized medical trial in Neurology confirmed that 12-month spermidine supplementation had no vital helpful impact on reminiscence efficiency as in contrast with a placebo5. However a 2018 examine within the American Journal of Scientific Diet noticed a lower in all-cause mortality related to elevated spermidine consumption from meals sources6.
The brand new examine in Nature Cell Biology solely provides to the rising proof in favor of spermidine advantages. The researchers discovered that spermidine may enhance the cardioprotective and anti-arthritic advantages of intermittent fasting and calorie restriction7.
Good Pure Sources of Spermidine
There are a number of meals with spermidine on the market, together with legumes like soybeans, peas, and lentils, cruciferous greens like broccoli and cauliflower, and fermented meals like miso and cheese.
“This might be a part of why the Mediterranean weight loss plan is so profitable in serving to forestall coronary heart illness, metabolic syndrome, and different anti-inflammatory or growing older processes,” explains Dr. Serena Goldstein, ND, “as a result of quantity of meals it typically incorporates which are excessive in spermidine.”
Whereas all cheese has some spermidine, longer-aged ones like Manchego and Gruyère are usually richer within the polyamine. And blue cheese particularly has been discovered to include a whopping 1.5 mg of the compound per 100 gram serving, practically double the quantity present in fermented soybeans like natto. “Blue cheese is among the richest pure meals sources,” says Sulack, “making it a novel and flavorful solution to assist long-term well being when tolerated nicely.”
As for which blue cheeses to decide on, the extra aged the cheese, the higher. “Blue Stilton, specifically, has been singled out in lab assessments as exceptionally excessive [in spermidine],” he says. He additionally recognized French Roquefort and Italian Gorgonzola as different nice sources.
“The fermentation course of used to age these cheeses will increase their spermidine content material, which is why they stand out in comparison with youthful or much less fermented varieties,” he says.
Different Well being Advantages of Blue Cheese
Spermidine apart, cheese might be a part of a nutritious diet. Whereas blue cheese won’t appear to be a well being meals, Sulack says it’s extra nuanced than that. So is blue cheese good for you?
“I consider the popularity of cheese relies upon solely on context and high quality,” he says. “Sure, processed cheese merchandise loaded with components deserve criticism. However conventional cheeses, particularly uncooked, grass-fed, or fermented varieties, can provide actual dietary worth. They’re wealthy in protein, calcium, vitamin K2, and even probiotics.”
Bakovic agrees. “Cheese, usually, typically will get a ‘unhealthy’ rep resulting from its’ saturated fats content material and the belief that it incorporates increased quantities of dietary sodium,” she says. However moderation is the important thing to reaping the advantages with out absorbing any downsides.
“It isn’t inherently ‘unhealthy,’” Bakovic continues. “The consumption of cheese in extra, or routinely selecting highly-processed cheese merchandise, nonetheless, has been related to damaging impacts to continual illness danger elements, together with coronary heart illness as one instance.”
However should you select good-quality blue cheeses and eat it moderately, you’ll open the door to a variety of well being advantages linked to its richness in calcium and probiotics. Sulack cites a 2012 examine in Medical Hypotheses showcasing the anti-inflammatory advantages of French Roquefort particularly, notably as regards to the safety of arterial partitions and the promotion of tissue regeneration8.
“This may increasingly assist clarify the ‘French paradox,’ the place charges of heart problems stay low regardless of a wealthy weight loss plan,” he explains. “Blue cheese additionally helps intestine well being via pure probiotics, and it offers calcium and vitamin K2, that are important for bone power.”
Don’t Break Your Dairy Guidelines for Blue Cheese
Regardless of these advantages, it’s honest to say blue cheese won’t be for everybody. Sure, the bitter, intense taste of blue cheese is hard for some to swallow. However Goldstein additionally notes a preponderance of intolerances and allergy symptoms — not simply to blue cheese, however to dairy usually. And the blue cheese advantages aren’t value struggling over any intolerances.
“Symptom-wise, when individuals have given up dairy, I’ve seen them shed some pounds, regulate their intestine well being, have decreased pimples, rashes, and really feel extra level-headed,” she says. “Nonetheless, I additionally consider there’s a cultural piece (i.e. some cultures tolerate it higher than others), the way it’s consumed (i.e. in a relaxed surroundings, moderately), the way it’s made (particularly exterior of the U.S. the place there tends to be extra manufactured processes versus recent, and unprocessed).”
Nonetheless, if it’s to your style and your system tolerates it, blue cheese is a superb possibility so as to add to a wholesome, balanced weight loss plan. “As all the time, meals needs to be customized,” says Sulack. “However in the appropriate context, blue cheese isn’t only a culinary indulgence, it’s a practical meals.”
