Here is the text without the code and formatting: High blood pressure can be managed with dietary changes. Here are some foods that patients should avoid or limit. Processed meats such as bacon and hot dogs contain preservatives like sodium nitrate, which can raise blood pressure. Canned foods also have preservatives that can contribute to high blood pressure. High-sodium foods like pickles and potato chips can cause your body to hold onto fluid, leading to higher blood pressure. Fried foods such as French fries and chicken strips are typically cooked in oil, which is high in calories and fat. Fatty meats contain a lot of saturated and trans fats, which can raise blood pressure. Vegetable oils and margarine are also high in trans fat, which is another factor that contributes to high blood pressure. Table salt is high in sodium, so patients should limit their intake of it as well. Grapefruit contains a compound called furanoocoumarin, which can interact with certain medications for people with high blood pressure. In general, it's a good idea for people with high blood pressure to focus on eating a variety of whole, unprocessed foods like fruits, vegetables, lean proteins, and whole grains.
