Trying to eat healthier can be a bit of a challenge at times, especially when new or unfamiliar foods are incorporated into the mix. But when it comes to finding a nutrient-rich supplement for protein, registered dietitian Raina Childers says tofu can be a "stealthy" addition.

Childers, who works at HealthPoint Fitness in Cape Girardeau, says tofu is a versatile food that can sometimes be masked well in dishes due to its versatility and ability to take on neighboring flavors.

"That neutrality provides you an opportunity to flavor it in a variety of ways, so you can make it Mexican or Thai or add Asian seasonings or barbecue; you can do a lot of things with it," she says.

Katie Urhahn, a registered dietitian at Saint Francis Medical Center in Cape Girardeau, agrees that starting slowly may help make the transition to tofu easier for a family.

"Start slow by adding it to foods that are already familiar, as with any fruits, vegetables, all together," she says. "I would say start with adding it to scrambled eggs, maybe putting it in lasagna instead of your ricotta cheese. Soups would be a really easy place to add it."

Before anyone new to tofu begins to use it in recipes, though, both dietitians say it is important to learn a bit more about the product.

Tofu, or bean curd, is made from coagulated soy milk, which is then pressed into soft blocks. The consistency of tofu can vary based its water content, from silken to extra firm.

"The more it coagulates, you would use it as a substitute like yogurt or as a substitute like cheeses," Urhahn says. "[It's] not really anything to be afraid of, it's just a matter of getting used to it."

Urhahn recommends initially substituting half of a dish's protein ingredients, like cheese or meat, with tofu to slowly acclimate to the product.

"As you get used to it, add a little more, add a little more," she says.

Tofu is a protein-rich food, which Childers says is rare because it is plant based, and most protein-rich foods come from animal sources.

"Because it's a vegetarian protein, it's a good non-meat source of protein, iron, calcium; it has good Omega-3 fats that are known to help lower cholesterol, reduce the risk of heart disease," Urhahn says. "[Omega-3 fats are] good for reducing inflammation throughout the body, which is beneficial to reducing the risk of all disease."

Along with being comparable in protein content, Childers says tofu is cheaper than meat, making it an affordable substitute.

Tofu also can replace other ingredients in dishes, such as cream cheese and mayonnaise, to create healthier, lower-fat alternatives.

Childers says firm block tofu can be used as an egg substitute or in place of meat in stir-fry, soup and other meals. Silken tofu can be used in smoothies, soups, sauces, puddings, cream pies, dressings and dips, among other dishes.

"I would start with the silken tofu because it's easiest to disguise. It's hidden and it blends in well," Childers says.

As people become more comfortable with tofu, they can move toward the more firm types and get more creative with it in meals.

"Because of its versatility and that neutral flavor, it does love big flavors to be added to it," Childers says. "It's very porous, so it becomes more of what it's cooked with and flavored with. So some people marinate it, some people use spices, a little stronger spices."

Urhahn says tofu stores well in sealed containers in the refrigerator and should be kept in water. Silken tofu can be shelf-stable and put in the refrigerator once opened. Tofu of varying consistencies can be purchased at most local grocery stores.
