The Benefits of Whole Food Nutrition

There is something to be said about including whole, minimally processed foods in your eating plan. In fact, consuming nutritious whole foods has wellresearched health benefits.  

Unfortunately, many people gravitate toward the convenience of ultra-processed foods such as chips or cookies, which contribute little to no nutrition but provide plenty of “empty” calories. Ultra-processed foods make up more than half of the total dietary energy consumed in the United States (1). Although these products may be convenient, population-based studies have shown that these foods are typically full of unhealthy fats and salt, low in dietary fiber and protein, and contain very few vitamins or minerals (2). Engineered for taste and reward, ultraprocessed foods may drive overconsumption and weight gain. Fortunately, there are many whole food options that are as delicious and convenient as they are nutritious. 

The benefits of whole foods should convince even the pickiest eater to grab a healthier option off the shelf. Whole fruits and vegetables, for example, are nutrient dense, rich in vitamins, minerals and fiber, and relatively low calories. Additionally, extensive studies suggest people who eat more fruits and vegetables live longer and healthier lives (3,4). Plus, a diet that includes many different fruits and vegetables, whole grains, and lean proteins delivers nutrients in their naturally occurring forms as well as a full spectrum of vitamins referred to as vitamers. This diversity of vitamers ensures you receive the full benefits of the vitamin. 

Whole food benefits don’t just come from vitamins and minerals, but from powerful phytonutrients as well. Phytonutrients are unique compounds found in fruits, vegetables, and other plant-based foods that support good health (5).  Their unique benefits include maintaining healthy function of blood vessels and the immune system, as well as the retina of the eye (6). Additionally, resveratrol, a well-studied phytonutrient identified in more than 70 different plant species, has been studied for its benefits in supporting metabolism and healthy aging (7, 8).  

Ultra-processed foods – although convenient – offer little nutrition overall. Scientific research demonstrates that an increase in dietary intake of ultra-processed foods results in deterioration of the nutritional quality of the overall diet (2,9,10). 

Luckily, overwhelming scientific evidence supports the benefits of a diet full of fruits, vegetables, and other whole, minimally processed foods. These nutrient dense foods are rich in vitamins, minerals, and fiber and are relatively lower in calories when compared to ultra-processed foods. Eating whole foods contributes so many benefits that the typical “junk food” diet simply cannot
