Key Takeaways
- In line with a latest examine, consuming 100% orange juice might play a optimistic function in persistent irritation and oxidative stress.
- Combatting persistent irritation can have a optimistic impact on immune well being.
- Whereas the examine confirmed an total optimistic impact of consuming 100% OJ, extra analysis is required to verify its potential advantages on irritation and oxidative stress.
Managing irritation and oxidative stress could also be so simple as sipping on a glass of 100% orange juice, in keeping with a brand new evaluate and meta-analysis.
The examine was funded by an unrestricted grant by the Florida Division of Citrus and was revealed in Advances of Vitamin in October.
Irritation and Oxidative Stress
Irritation and oxidation are pure processes that happen within the human physique. They are often the results of various factors, akin to being uncovered to cigarette smoke, consuming massive quantities of sugar, and residing in a polluted atmosphere.
When there’s an excessive amount of persistent irritation or there’s an imbalance between free radicals and antioxidants within the physique (oxidative stress), there may be well being penalties.
For instance, if oxidative stress isn’t managed and too many free radicals are current within the physique with out sufficient antioxidants to counteract them, an individual could be at the next threat for diabetes, hypertension, and sure cancers.
Oxidative stress also can result in persistent irritation, a situation that’s linked to heart problems, most cancers, diabetes mellitus, persistent kidney illness, non-alcoholic fatty liver illness, and autoimmune and neurodegenerative issues.
Power irritation may also be associated to weight problems, bodily inactivity, eating regimen, and disturbed sleep.
Power irritation has additionally been proven to have damaging results on immune well being. Amid the COVID-19 pandemic, this relationship has been garnering extra consideration. In actual fact, latest information has proven that low-grade persistent irritation can negatively have an effect on the outcomes of sufferers with COVID.
Having persistent irritation also can impair regular immune operate, resulting in elevated susceptibility to infections.
Throughout being pregnant and childhood, systemic persistent irritation can improve an individual’s threat for creating non-communicable ailments like coronary heart illness and diabetes.
Advantages of 100% OJ
Taylor Wallace, PhD, CFS, FACN, principal & chief govt officer of Suppose Wholesome Group, adjunct professor within the Division of Vitamin and Meals Research at George Mason College, and an investigator on the examine, tells Verywell that “proof is rising” about whether or not consuming 100% OJ performs a optimistic function in irritation and oxidative stress.
An excessive amount of oxidative stress and persistent irritation can happen for a wide range of causes, together with our dietary decisions. In line with Wallace’s analysis, 100% orange juice could be an addition that would assist struggle irritation and stress.
What the Examine Regarded At
The examine included a scoping evaluate, a scientific evaluate, and a meta-analysis that investigated the potential associations between 100% orange juice and markers of irritation or oxidation in wholesome adults in addition to in folks in danger for persistent ailments.
This is how the researchers broke down the analysis:
- The scoping evaluate included 21 research that included 307 wholesome adults and 327 adults in danger for illness.
- The systematic evaluate targeted on 16 research that measured the six most reported biomarkers associated to irritation and oxidative stress within the physique.
- Of the 16 research included within the systemic evaluate, solely 10 have been used for the meta-analysis.
What the Knowledge Confirmed
The findings counsel that consuming 100% OJ considerably reduces a well-established marker of irritation known as interleukin 6 in each wholesome adults and adults at excessive threat of creating persistent ailments.
The outcomes confirmed that, basically, 100% OJ both had helpful or no impact on oxidative stress or irritation. Ingesting OJ didn’t trigger a rise in both persistent irritation or oxidative stress.
Limitations
The evaluation didn’t embody numerous scientific trials, the research that have been included had small pattern sizes, and there was a average threat of bias when evaluating the person research included.
Nonetheless, the outcomes did get researchers excited about the potential advantages of 100% OJ on irritation and oxidative stress within the physique.
Different Research
The examine isn’t the primary to counsel that 100% OJ might assist cut back irritation and oxidative stress.
The outcomes of a examine revealed in Meals and Vitamin Analysis in 2015 steered that adults who drank 750mL (3 cups) of orange juice for eight weeks as a part of their common eating regimen skilled enhancements in a number of anti-inflammatory and oxidative stress markers.
Whereas it is an older examine, analysis revealed within the Journal of Vitamin that checked out wholesome adults who consumed 500mL (2 cups) of orange juice every day for 2 weeks confirmed a major discount in a marker for oxidative stress.
Is 100% Juice Wholesome?
100% orange juice is made with just one ingredient: oranges. It incorporates no added sugars. One cup “counts” as a fruit serving, in keeping with america Division of Agriculture (USDA).
The 2020–2025 Dietary Tips for Individuals (DGAs) recommends that vegetables and fruit make up half of an individual’s plate at every meal, with not less than half of the entire fruit servings coming entire fruit.

Because the researchers of the newest examine spotlight, 100% fruit juice has comparable vitamin and mineral content material to equal portions of the entire fruit counterpart.
Oranges, and orange juice, naturally include necessary vitamins like folate, vitamin C, and thiamin, together with pure polyphenols.
“100% orange juice can completely be part of an total nutritious diet,” Elizabeth Shaw, a California-based registered dietitian and the proprietor of Shaw Simple Swaps, tells Verywell, including that fruits and veggies are a helpful a part of a eating regimen that additionally consists of different healthful meals, “like low mercury fish, beans, and legumes.”
