New research conducted by Penn State suggests that broccoli may be considered a superfood. It has been known for some time that the sulfur compounds present in broccoli have anti-inflammatory properties and are associated with lower cancer and heart disease risks. The recent study indicates that broccoli may help intestinal barrier function in mice, which could prevent disease. The wall of the small intestine regulates what passes into the body, allowing nutrients and water to pass while keeping undigested food and bacteria out. Broccoli contains molecules that bind to receptor sites in the small intestine, enhancing the barrier function of the intestinal wall. The research found that these molecules bind to aryl hydrocarbon receptor (AHR) sites in the small intestine of mice, affecting the functioning of cells in the intestinal wall.
The study involved feeding a group of mice a 15% broccoli diet, which is equivalent to a human intake of 3.5 cups of broccoli per day. The control group was fed their normal diet. Analysis of their tissues showed that mice who did not consume broccoli did not have any AHR activity. This changed their intestinal barrier function, causing food to travel through the small intestine more quickly, reducing the number of goblet cells, and decreasing the amount of mucus. These mice also had fewer Paneth cells, lysosomes, and enterocytes. The researchers concluded that those mice who were not fed broccoli had gut health that was compromised in ways that are linked to disease.
Broccoli is considered a superfood because it is packed with nutrients that are essential for good health, such as vitamins C and K, fiber, and folate. It also contains phytonutrients such as sulforaphane, which have anti-cancer properties. Additionally, broccoli is low in calories and high in water content, making it a great choice for those looking to maintain a healthy weight.
Nutritionist Shereen Jegtvig explains that superfoods are nutrient-rich foods that are considered to be especially beneficial for health and well-being. Examples of superfoods include berries, leafy greens, nuts and seeds, whole grains, fish, and legumes. Jegtvig advises eating cruciferous vegetables like broccoli at least a few times per week. For those consuming a plant-based diet, broccoli can be a great source of plant-based calcium.
Overall, broccoli is a versatile and budget-friendly vegetable that can be enjoyed by people of all ages and cultural diets.
