Eat More Fruits and Vegetables to Reduce Inflammation and Oxidative Stress, New Study Finds
We understand that fruits and vegetables are beneficial for our health. However, a new study presents concrete evidence of their advantages, demonstrating that the highest consumers show significantly lower levels of inflammation and oxidative stress.
A Study of 1,000 Adults Aged 18 to 85
The researchers analyzed data from 1,000 men and women aged 18 to 85. Participants completed a questionnaire regarding their dietary habits and provided blood samples every 12 weeks to measure various biomarkers of inflammation and oxidative stress.
By examining fruit and vegetable intake, scientists were able to compare levels of inflammatory markers and oxidative stress between low and high consumers of these foods.
Up to 29% Less Inflammation in the Biggest Fruit and Vegetable Eaters
The findings are clear. Individuals who consumed more than 7 servings of fruits and vegetables daily had significantly lower concentrations of several inflammatory markers:
- Interleukin-6 (IL-6): -29% compared to low consumers (less than 2 to 3 portions per day)
- Tumor necrosis factor (TNF-α): -32% compared to low consumers
In terms of vegetable intake alone, individuals who consumed more than 3 servings daily had 39% lower IL-6 levels than those who consumed fewer than 3 servings.
Heavy Consumers Also Have 18% Reduced Oxidative Stress
Oxidative stress, which occurs when free radicals are not sufficiently neutralized by antioxidant defenses, is linked to many chronic diseases.
Once again, the heavy consumers of fruits and vegetables had better outcomes. Those who ate more than 7 servings per day had F2-isoprostanes levels, a marker of oxidative stress, that were 18% lower than those who consumed the least (2 to 3 servings).
Video of the Day
Additionally, their antioxidant capacity, measured by FRAP and ORAC tests, was significantly higher, indicating better protection against free radical damage.
Aim for at Least 5 Fruits and Vegetables a Day
This study reinforces public health recommendations that promote the consumption of a wide variety of fruits and vegetables, advocating at least 5 portions per day.
These foods not only provide numerous beneficial nutrients and antioxidants but may also actively combat harmful processes such as chronic inflammation and oxidative stress, which are associated with cardiovascular disease, diabetes, cancer, and accelerated aging.
So don’t hesitate to include fruits and vegetables in every meal! Your body will appreciate it.
Our Answers to Your Questions About Fruits, Vegetables, and Inflammation
What Are the Best Anti-Inflammatory Fruits and Vegetables?
All fruits and vegetables possess anti-inflammatory properties due to their antioxidants, vitamins, and minerals. Some that stand out include berries (rich in polyphenols), citrus fruits (vitamin C), green vegetables (lutein), broccoli (sulforaphane), and tomatoes (lycopene).
Should You Eat Organic to Benefit from Anti-Inflammatory Properties?
Choosing organic helps reduce exposure to pesticides. However, the most crucial aspect is to consume a wide variety of fruits and vegetables, whether they are organic or not. Washing and peeling them can help lessen pesticide residues.
Are Canned or Frozen Fruits and Vegetables Just as Good?
Research indicates that fresh, frozen, and canned fruits and vegetables have comparable nutritional value. The key is to select products without added sugar or salt. A helpful tip: homemade options allow you to control all the ingredients!
How to Properly Preserve the Nutritional Benefits of Fruits and Vegetables?
To maintain vitamins and antioxidants, favor short cooking times (steaming, stir-frying). Cook crunchy vegetables without over-blending soups. Keep them well-cooled and quickly consume homemade preparations.
