A recent article in the German nutrition journal Ernährungs Umschau has sparked renewed debate about the role of grains in a healthy diet, challenging long-held beliefs about their nutritional value. For decades, grain products were promoted as cornerstones of conscious eating, but increasingly, they face criticism and are often demonized in popular diet trends.
The article highlights that grains – specifically rice, corn, and wheat – provide approximately 45 percent of the world’s caloric intake. While wheat offers the most complete nutritional profile among these three, the publication acknowledges a growing awareness of conditions like celiac disease, wheat allergy, wheat-dependent exercise-induced anaphylaxis (WDEIA), and non-celiac gluten sensitivity (NCGS) that necessitate eliminating wheat and related grains, including spelt, einkorn, and emmer, from the diet.
The German Society for Nutrition (DGE) emphasizes the importance of grains, grain products, and potatoes as foundational elements of a healthy and sustainable diet, alongside fruits, vegetables, legumes, and nuts. The DGE specifically advocates for choosing whole grain varieties whenever possible, noting their superior health benefits. These foods provide essential carbohydrates for energy, as well as protein, vitamins, and minerals like B vitamins, iron, zinc, and magnesium. The DGE also points out the importance of fiber and secondary plant compounds, particularly in whole grain products.
The distinction between whole grains and refined grains is crucial. According to the DGE, whole grain flour, bread, pasta, flakes, and natural rice are made from the entire grain kernel – bran, germ, and endosperm – retaining their valuable nutrients. Conversely, products made from low-extraction flour, such as white bread and wheat mixed bread, and polished rice have had the bran and germ removed, significantly reducing their nutritional content. The DGE recommends a gradual increase in whole grain consumption, allowing the digestive system to adjust.
While the Ernährungs Umschau article and the DGE both acknowledge the benefits of grains, they also implicitly recognize the increasing prevalence of sensitivities and allergies. The Ernährungs Umschau article, available for purchase online, offers a detailed overview of the data surrounding the advantages and risks of a grain-rich diet, intended as a resource for nutritional counseling. The DGE recommends a daily fluid intake of at least 1.5 liters to aid digestion, particularly when increasing fiber intake from whole grains.
Recent reporting from Heilpraxisnet.de indicates ongoing research into the health effects of plant-based compounds, including those found in grains, with a focus on potential benefits related to arterial health. However, the article does not offer specific details on the findings.
