Eating fruit and vegetables daily is important for good health, but how much fruit and vegetables is necessary? What about those five servings?
Fruits and vegetables are essential foods for human nutrition because they contain a large amount of minerals and vitamins, thereby offering many benefits to humans. In fact, according to the Spanish Society of Community Nutrition, fruits and vegetables are among the food groups to include in every main meal. But why are fruits and vegetables so important? Biologically, the human body needs a certain amount of vitamins and minerals daily, which fruits and vegetables provide. Additionally, they are rich in fiber, antioxidants, are cholesterol-free, and help keep the body hydrated, as they contain between 75% and 90% water.
For all these reasons, fruit has been part of the human diet for centuries. It was so important that, in the ancient world, it was considered "the food of the gods," according to poets Homer and Ovid. Centuries later, their colors and shapes were the protagonists of still lifes that are today displayed on the walls of the world's finest art galleries. In intercontinental travels, the discovery of exotic fruits previously unknown in the West opened a new path of flavors like pineapple, tomato, or avocado, which are now so present in Western kitchens. It's clear that the veneration for fruit comes from long ago. What is more recent is the debate about how many fruits should be eaten per day and how and when to do it.
Each person, depending on their age, sex, and physical activity, has specific dietary needs, including for fruits and vegetables. But, as with all other foods, there are general recommendations—in this case, five servings of fruit and vegetables per day. This recommendation has been widely disseminated by health organizations around the world and is based on evidence suggesting that a diet rich in fruits and vegetables can reduce the risk of chronic diseases such as heart disease, type 2 diabetes, and certain types of cancer. However, it is reasonable to question whether this specific recommendation is necessary and appropriate for everyone.
So, what are the appropriate amounts of fruits and vegetables? The general consensus in nutrition guides and recommendations from the WHO and other health authorities is that adults should consume at least 400 grams of fruits and vegetables per day, which is approximately five 80-gram servings. This advice is based on research linking the intake of five daily servings to a lower risk of death from diseases such as cardiovascular disease, cancer, and strokes. However, to comply with health recommendations, it is important to understand that typically, a serving is about 80 grams, which could be, for example, a small apple, a medium banana, or half a cup of cooked vegetables.

Benefits of Eating Fruit and Vegetables Daily
Cardiovascular Health: Higher fiber intake reduces the risk of cardiovascular diseases and obesity.
Varied Nutrient Content: Fruits, vegetables, and legumes offer a wide range of nutrients, including fiber, vitamins, minerals, and antioxidants.
Whole Foods vs. Beverages: Consuming whole fruits and vegetables is more effective than adding fiber to beverages for satiety and intake control.
Consider Individual Needs: Nutritional requirements vary based on factors like age, sex, physical activity level, and health conditions.
Quality Matters: Opt for whole fruits over sugary juices for better health outcomes, focusing on varieties with a low glycemic index.
In a study with over 100,000 adults, those who consumed five servings of fruits and vegetables per day were less likely to die prematurely and from cancer, cardiovascular diseases, and respiratory diseases. Those who achieved better results ate three portions of vegetables, such as steamed spinach, kale, broccoli, and beta-carotene-rich vegetables like carrots, and two daily servings of fruit, such as a banana or strawberries, were less likely to die prematurely compared to participants who consumed fewer fruits and vegetables.
However, neither fruit juice nor starchy vegetables, such as peas and potatoes, had positive effects. There was also no improvement in mortality when comparing data from people who ate more than five servings of fruits and vegetables daily. According to the authors, there comes a point where the body can no longer utilize more of those beneficial nutrients such as vitamins, minerals, and fiber. Therefore, it is not necessary to consume more than five servings a day. It should be clear that in nutrition, common sense should be followed, or based on experience that leads people to live longer. Experience shows that one of the populations that lives the longest is the one that follows the Mediterranean diet, which does not consume more than five fruits a day. Eating more could mean that other necessary foods like proteins and slow carbohydrates are not consumed.
Myths and truths about fruit and vegetables
Myth 1: Eating fruits makes you gain weight due to their sugar content. Although fruits contain natural sugars, such as fructose, they are accompanied by fiber, vitamins, and minerals that are beneficial to health. Fiber helps slow down sugar absorption, preventing sharp spikes in blood glucose levels; therefore, moderate fruit consumption is healthy and should not be seen as a direct cause of weight gain.
Truth 1: Fruits and vegetables are good for health. Loaded with essential nutrients, vitamins like A, C, and E, and minerals like potassium and magnesium, fruits and vegetables are vital for maintaining health. In fact, numerous studies have shown that their regular consumption can reduce the risk of chronic diseases, including heart diseases, type 2 diabetes, and some types of cancer.
Myth 2: Fresh fruits and vegetables are more nutritious than frozen ones. Many people believe that fresh fruits and vegetables are inherently superior to frozen ones in terms of nutrition. However, frozen fruits and vegetables are usually processed at their peak of ripeness, which means they can effectively retain their nutrients. In some cases, they may even retain more nutrients than fresh ones that have been stored for long periods.
Truth 2: Consuming a variety of fruits and vegetables is beneficial. Not all fruits and vegetables are equal in terms of nutritional composition; therefore, eating a wide variety of these foods ensures a diverse intake of nutrients. Additionally, varying the colors in your selection can help obtain a complete spectrum of vitamins and minerals.
Myth 3: Drinking fruit juice is as good as eating whole fruits. Although fruit juice provides some of the vitamins and minerals present in whole fruits, it often lacks fiber and may contain added sugars. Additionally, it is easier to consume large amounts of calories more quickly with juice than by eating the whole fruit, which can contribute to weight gain.
This comprehensive article and its exploration into the myths and truths surrounding the consumption of fruits and vegetables underscore a fundamental lesson in nutrition: balance and moderation are key. While consuming five servings of fruits and vegetables daily is associated with a reduced risk of premature death and several chronic diseases, exceeding this amount does not necessarily offer additional benefits. This finding emphasizes the importance of a well-rounded diet, where overconsumption of one food group does not displace other vital nutrients, such as proteins and complex carbohydrates.
Moreover, the discussion on the myths and truths about fruits and vegetables provides valuable insights into common misconceptions, such as the fear of weight gain from fruit sugars or the superiority of fresh produce over frozen. These clarifications encourage informed choices among consumers, promoting a varied and balanced diet that is not only rich in essential nutrients but also adaptable to individual health needs and lifestyle.
Ultimately, adopting a diet similar to the Mediterranean diet, which integrates a diversity of food groups including moderate portions of fruits and vegetables, can lead to a healthier, longer life. This approach, backed by both scientific research and centuries of dietary tradition, offers a practical blueprint for effective nutritional habits. As we continue to uncover more about the benefits of fruits and vegetables, let us remember that the simplest changes in our daily diet can have profound impacts on our overall health.
