In one sentence, describe what the following article is about:

Although your body requires sodium in small amounts, consuming too much sodium is bad for you and can lead to hypertension, heart disease and stroke. If you suffer from high blood pressure, take steps to reduce your sodium intake:  Do not add salt to foods when cooking but use other spices instead (cumin, lemon pepper, fresh herbs). Rinse canned foods to remove sodium. Buy foods that are labeled “low sodium” or “sodium free.” Avoid processed foods, such as crackers, fried items, and baked goods, that often are high in sodium. Also avoid eating fast food and ask for reduced sodium when ordering in restaurants. A high fiber diet may help reduce your risk of hypertension. Fortunately, it’s easy to get fiber from the healthy foods you’re likely already eating. Incorporate more whole grains, fresh veggies, and fruit with the skin on it into your diet. This will help you consume at least 25 grams of fiber each day.  Make sure you get at least six to eight servings of whole grains every day. Switch refined grains to whole grains, such as brown rice and whole wheat pasta and bread. Potassium-rich foods should be a part of your hypertension management diet. Foods you should add include sweet potatoes, tomatoes, kidney beans, orange juice, bananas, peas, potatoes, dried fruits, melon and cantaloupe. Keep your target potassium levels moderate (around 2,000 to 4,000 mg a day). Dark chocolate may help lower blood pressure, though it might not work the same for everyone. Eat dark chocolate whenever you’re craving a treat. Choose a bar that has at least 70% cocoa.  Eat a half an ounce of dark chocolate that has at least 70% of cocoa per day.  Because dark chocolate is high in calories, be sure not to overindulge. Besides being bad for blood pressure, caffeine and alcohol also have other negative health effects to you and your baby during pregnancy. Thus, you should avoid both, especially if you suffer from high blood pressure.  Drinking caffeine during pregnancy has been linked to declined placental blood flow and a risk of miscarriage. Although more studies are needed to confirm the effects of caffeine, it is best to switch to decaf during your pregnancy.  High alcohol consumption is known to raise blood pressure and it is also known to have negative effects on your unborn baby. Before drinking any alcohol, even just one glass of wine, consult your doctor. A clinical study demonstrated that systolic blood pressure can be lowered by adding these foods to your diet.  Add low-fat or fat-free dairy products (such as milk, cottage cheese, yogurt) to your diet. If you are lactose intolerant, try a milk alternative, such as almond, coconut, or hemp milk.  You can also try soy milk, but you may want to limit soy products during pregnancy since it may increase estrogen levels in your fetus.  Go easy on the amount of cheese you eat (even low-fat) due to their high sodium content.

Summary:
Avoid salt and high-sodium foods, which increase your risk. Consume more whole grains and fresh produce to get fiber. Eat potassium-rich foods to help lower your blood pressure. Indulge with dark chocolate. Avoid alcohol and caffeinated drinks. Add soy and low-fat milk products to help lower your blood pressure.
