Most of us have heard the familiar advice to eat more fruits and vegetables. We nod, acknowledge it as common sense, and then carry on with our usual routines. But a sweeping new study published in BMC Medicine in 2025 puts hard numbers behind that advice, and the figures are staggering. Worldwide, insufficient intake of fruits and vegetables contributed to approximately 2.6 million deaths in 2021 alone. That is not a projection or an estimate of future risk. It is what happened in a single year.
The study, led by researchers from Peking Union Medical College Hospital and Heidelberg University, drew on the Global Burden of Disease (GBD) 2021 database to analyze trends across 204 countries and territories from 1990 to 2021. It is one of the most comprehensive assessments ever conducted of the relationship between what people eat, specifically how much produce they consume, and how much disease and death can be attributed to falling short.
How Far Short Are We Falling?
The numbers paint a sobering picture. In 2021, the global average intake of fruit was just 121.8 grams per day, roughly equivalent to one small apple. Vegetable intake averaged 212.6 grams per day, about a cup and a half of cooked vegetables. Those amounts might sound reasonable until you compare them to what the researchers identified as optimal: 340 to 350 grams per day for fruit and 306 to 372 grams per day for vegetables. In other words, the average person on this planet is eating only about one-third of the fruit and roughly two-thirds of the vegetables that would best protect their health.
To put it in practical terms, optimal fruit intake is closer to three or four servings per day, and optimal vegetable intake lands at about four or five servings. The World Health Organization recommends a minimum of 400 grams of combined fruits and vegetables daily, but even that well-known target falls below the optimal levels identified in this research.
The Cardiovascular Connection
If you have ever wondered which diseases are most affected by low fruit and vegetable intake, the answer is clear: cardiovascular disease dominates the picture. Among the 1.7 million deaths attributable to insufficient fruit intake in 2021, cardiovascular diseases accounted for 83.7%. Among the 0.9 million deaths linked to insufficient vegetable intake, cardiovascular diseases accounted for 79.3%. Heart attacks, strokes, and other cardiovascular events are far and away the leading cause of death tied to this dietary shortfall.
This makes physiological sense. Fruits and vegetables are rich in dietary fiber, which helps lower blood pressure and cholesterol levels while reducing platelet aggregation. They also provide powerful antioxidants, including carotenoids, vitamin C, and flavonoids, that can lower blood homocysteine levels, reduce systemic inflammation, and improve the health of small blood vessels. A meta-analysis cited in the study found that a combined intake of just 200 grams per day of fruits and vegetables was associated with an 8% reduction in cardiovascular disease risk. Increasing intake to 500 or 800 grams per day reduced the risk by 22 and 28%, respectively.
Beyond cardiovascular disease, the study also found meaningful contributions to deaths from diabetes and kidney diseases (12 to 14% of the attributable mortality), neoplasms or cancers (about 4 to 6%), and respiratory infections, including tuberculosis. These categories reinforce what researchers in integrative medicine have long emphasized: the foods we eat daily, or fail to eat, set the stage for the chronic diseases that ultimately claim the most lives.
A Tale of Two Worlds
One of the most troubling findings in this study is the widening gap between wealthier and poorer nations. Countries with higher sociodemographic index (SDI) scores, reflecting better education, higher incomes, and lower fertility rates, consume nearly twice as much fruit and triple the vegetables as lower-SDI countries. And the gap is getting worse. Between 1990 and 2021, the difference in fruit intake between higher and lower SDI regions grew by 62.3%, while the difference in vegetable intake grew by 26.3%.
The consequences follow predictably. Higher-SDI countries experienced a 47% reduction in age-standardized mortality from insufficient fruit intake over the three-decade period, compared to only a 17.7% reduction in lower-SDI countries. For vegetables, the disparity was even more dramatic: a 58.8% reduction in higher-SDI regions versus 26.8% in lower-SDI regions.
In 2021, the highest mortality rates from suboptimal fruit intake were found in Central Sub-Saharan Africa, Southern Sub-Saharan Africa, and Oceania. For vegetables, the hardest-hit regions were again in Sub-Saharan Africa, along with countries like Afghanistan, where the age-standardized death rate from inadequate vegetable intake was 95.4 per 100,000 people, the highest in the world. These are places where poverty, food insecurity, inadequate storage and transportation infrastructure, and climate instability conspire to keep nutritious produce out of reach for millions.
Good News in the Trend Lines
Despite the enormity of the problem, there is encouraging news. Age-standardized mortality rates from insufficient fruit intake declined by 35% globally between 1990 and 2021, and rates from insufficient vegetable intake declined by 45%. East Asia showed particularly dramatic improvement, with the most rapid declines in both fruit- and vegetable-related mortality, driven largely by economic growth that expanded the availability and diversity of produce.
The absolute number of deaths, however, increased over the same period (by 46.5% for fruit and 25.6% for vegetables), a reminder that population growth and aging can outstrip even meaningful per-capita improvements. We are making progress, but not fast enough.
Men, Older Adults, and the Age Factor
The study also revealed important differences by sex and age. Men carried a higher burden than women across the board. In 2021, the age-standardized death rate from insufficient fruit intake was 23.7 per 100,000 among males compared to 16.9 among females. For vegetables, the rates were 11.8 versus 9.1. These differences may reflect both biological vulnerability and behavioral patterns, including dietary choices and overall health-seeking behavior.
As expected, the disease burden climbed steeply with age. Mortality and disability-adjusted life years (DALYs) from inadequate produce intake were significantly higher in older age groups, though the reductions achieved between 1990 and 2021 were most pronounced among individuals aged 80 and older. For those of us past 50, the message is straightforward: the cumulative effects of decades of suboptimal intake have real consequences, and every additional serving matters more as we age.
What This Means for Your Plate
For readers of this blog, many of whom are already pursuing a healthier path into their second half of life, the implications are deeply practical. The optimal intake targets identified in this study translate to roughly seven to nine total servings of fruits and vegetables per day. That may sound ambitious, but it is well within reach with intentional planning.
Think of it this way: two servings of fruit at breakfast (a banana and a handful of berries), a large salad with mixed greens and tomatoes at lunch (two to three servings of vegetables), a piece of fruit as an afternoon snack, and two to three servings of cooked vegetables at dinner. That pattern gets you to the range where the science says the greatest protection lies.
Variety matters as well. Different fruits and vegetables offer distinct phytochemicals, fiber types, and micronutrient profiles. Deeply colored produce, including dark leafy greens, berries, sweet potatoes, beets, and cruciferous vegetables like broccoli and cauliflower, tends to be the most nutrient-dense. But the single most important step is simply eating more produce overall, regardless of which specific items you choose.
A Stewardship Perspective
Scripture teaches that our bodies are temples of the Holy Spirit (1 Corinthians 6:19) and that we are called to be faithful stewards of the life God has given us. It is worth noting that the very first dietary instruction in the Bible was one of abundance: “I give you every seed-bearing plant on the face of the whole earth and every tree that has fruit with seed in it. They will be yours for food” (Genesis 1:29, NIV). The research reviewed here is a powerful modern confirmation that a plant-rich diet, grounded in the fruits and vegetables that were always part of the original design, remains one of the most effective ways to protect the health we have been entrusted with.
This is not about guilt or perfection. It is about recognizing that small, consistent choices add up. Every meal is an opportunity to nourish the body in a way that honors the Creator and gives us the energy, resilience, and vitality to fulfill the purposes we have been given.
The Bottom Line
The data from this landmark study could not be clearer. The world is eating far too little fruit and far too few vegetables, and the health consequences are measured in millions of preventable deaths every year. The good news is that progress is possible and, in many parts of the world, already underway. The even better news for any individual reader is that the remedy is remarkably accessible. It does not require a prescription, a medical procedure, or expensive technology. It requires a trip to the produce section and the daily discipline to fill half your plate with the foods that were designed to sustain you.
Eat the apple. Steam the broccoli. Toss the salad. Your heart, your blood vessels, and your future self will thank you.
