When Crohn’s disease flares up in the gut, it can be a painful and even debilitating problem, so preventing these sort of high-inflammation episodes is essential. Studies have shown that oily fish, such as salmon, mackerel and tuna, also possess high levels of omega-3 fatty acids, which are considered the “good” types of fat in our diet. Not only are these fats good for heart health, they also act as anti-inflammatory agents in the body, including the colon. Adding these delicious fish to your diet 2-3 times per week can significantly reduce the severity and frequency of flare-ups and discomfort.
