Food, specifically plant food, can be used as medicine to help reduce or lower your risk for certain diseases. One is heart disease. Two of the risk factors for heart disease, high blood pressure and high cholesterol, can be influenced by your food choices. If you are currently trying to lower one or both of those without having to resort to medication, you might want to try eating more plant foods.

Plant foods contain two different kinds of fiber. To lower your cholesterol, you need to consume more of the type we call soluble fiber. Soluble fiber combines with liquid in your stomach to make a gelatinous mixture that helps trap waxy particles of cholesterol. The mixture then proceeds through the digestive tract and leaves your body when you have a bowel movement. The most well-known source of soluble fiber is oats. Five to 10 grams of soluble fiber a day decreases your LDL cholesterol.

Other good sources of soluble fiber include dried beans and peas, nuts, barley, apples, pears, carrots and brussels sprouts. One excellent (but non-food) source of soluble fiber is psyllium, which is a plant used to make products that relieve constipation. One spoonful mixed in and cooked with your oatmeal everyday will do wonders for your cholesterol levels.

When it comes to lowering blood pressure, the first and most well-known food change you can make is to reduce the amount of sodium you eat. Fresh fruits and vegetables contain low amounts of sodium, which is a start in the right direction. But they also contain large amounts of potassium, a mineral that helps negate the bad effects of sodium. 

You should also try to consume 3500-4700 milligrams of potassium every day to help lower your blood pressure. However, taking potassium supplements is generally not recommended for people with high blood pressure.  A variety of potassium-rich foods should be eaten daily. The most well-known one, but actually not the best, is a banana.  Other good sources include potatoes (sweet and white), melon, peaches, raisins, tomatoes, pumpkin, and pears.

Many of the plant foods listed above are native to Ohio. Even though our availability of fresh, local produce is severely limited right now, start thinking about this spring. It is never too early to start planning for a garden. Growing at least part of your produce (even if it is just tomatoes and peppers) will give you superb tasting food that will help you maintain a healthy heart.

NCI5_POTATO

Fall is the perfect season to remind everyone to consume more sweet potatoes. Like pumpkin, they are usually enjoyed on Thanksgiving Day and then promptly forgotten about until the following year. But this vegetable should be eaten as frequently as possible, because it’s a winner. If your only experience eating sweet potatoes has been the canned variety, you need to try fresh.  The flavor and texture is far superior to canned, and easy to prepare.

 

Sweet potatoes are actually edible roots. Technically, they aren’t even a potato.  Some people call them yams instead of sweet potato, but they’re not really yams, either.  This is one confused vegetable with an identity crisis.  But one thing you don’t need to be confused about is how good they are for you.

A half cup of sweet potato provides over 200% of your DRI of vitamin A for the day. Vitamin A is a fat-soluble vitamin that provides the tools your body needs for the development and maintenance of healthy skin, hair, and mucous membranes. It also supports the immune system, reproduction, and oh yeah, vision. Want good eyesight?  Sweet potatoes are a better source of vitamin A than carrots.  They are also a good source of vitamin C, iron, thiamine, potassium (think about your blood pressure), vitamin E, and fiber.

Sweet potatoes can be baked, boiled, fried (like French fries) or steamed. Some restaurants offer a baked version as a side dish, usually with a brown sugar/butter spread. Those are incredibly good. But I also like to boil mine and make mashed sweet potatoes.

Are you a diabetic? Most diabetics steer clear of starchy carbohydrates like potatoes, but sweet potatoes contain compounds that can actually improve blood sugar regulation.  Depending on how you fix them, the glycemic index (GI) varies. The average GI value for a baked sweet potato is 94, but when boiled is only 46.

If you decide to mash, don’t try and peel the potatoes; they don’t peel as easily as white potatoes. Just cut the potatoes into chunks, cover with water and a lid, and bring to a boil. Once the water starts to boil, reduce heat to simmer, and cook until fork tender (about 40-45 minutes).

When the potatoes are tender, pour everything into a colander in the sink and let the steam and heat escape. Then nick the softened skin with a knife and just peel off.  Mash with a fork or potato masher and serve. For a little extra sweetness, try dribbling some maple syrup over the top. It will be like eating your vegetable and dessert at the same time!

sweet corna

 

One of summer’s greatest pleasures is enjoying a fresh ear of sweet corn at a backyard barbecue.   We eagerly await the corn harvest, and now it’s here!  Fresh sweet corn is available in most communities throughout the month of August.

Corn is a nutrient-rich vegetable.  One ear of corn is a good source of fiber, vitamin C, folate, magnesium, and potassium.  Corn is also a good source of lutein and zeaxanthin; phyto-nutrients that are linked to a reduced risk for cataracts and macular degeneration.  Corn has about the same amount of calories as an apple, but with one-fourth less sugar.

To reap the full nutritional benefits of corn, cook no longer than 10 minutes in boiling water to minimize nutrient loss. While boiling is the primary way most of us prepare corn, grilling is a popular and tasty alternative. Other ways to enjoy this nutritious vegetable include mixing it into pasta dishes, corn bread, soups and/or salads.

For a different taste, try seasoning corn with lime juice instead of butter.  Or combine cooked corn kernels with chopped scallions, red pepper, hot pepper sauce and lime juice as a quick salsa for meat, poultry or fish.

So what are you waiting for?  In a few weeks corn season will be over. Make plans to visit your local farmer’s market to pick up some sweet corn this weekend!

Are you getting enough potassium?  With emphasis on limiting sodium, potassium gets forgotten.   Yet, potassium can help in your effort to lower blood pressure.

In the U.S. one in three adults has high blood pressure and 56% do not have it under control.  So what does potassium have to do with it?  Potassium has been shown to lower blood pressure.  Studies have shown that people with higher potassium intakes have lower blood pressures.  High levels of potassium have also been associated with a reduced risk of bone loss, kidney stones and type 2 diabetes.  Low potassium levels are a predictor for stroke.    That’s why the new USDA Dietary Guidelines recommend you choose foods that provide more potassium.

Can’t potassium supplements work?  They can but they also can be hazardous, especially if you have kidney disease and don’t know it.   Having too much potassium in your blood can be life-threatening.    However, getting your potassium from foods usually does not cause any problems.  If you have a disorder that causes potassium retention, such as diabetes, kidney disease or heart failure, check with your doctor before increasing your potassium intake. 

Eating more fruits, vegetables, and low-fat dairy products is the BEST way to increase your potassium.   Bananas may come to mind when you hear the word potassium.  Bananas are a good source and so are potatoes, oranges or orange juice, beans, yogurt, milk, tomato products, spinach, cantaloupe, sweet potatoes, and prunes.  Follow “Choose My Plate” (http://www.choosemyplate.gov ) and fill up half your plate with fruits and vegetables.   You will be getting the potassium you need as well as other nutrients and fiber.  With summer here, now is the time to enjoy the fresh fruits and vegetables and get your potassium, too.
