There are so many ways to get this good-for-you protein into your daily diet. Here's how to do it — and why you absolutely should.

If you bypass tofu at salad bars, skip the meatless dishes at Chinese restaurants, and avoid edamame when you're out for sushi, well, it's time to give soy-based foods a second look. "Whole soy foods are a great substitute for meat," says Christine Gerbstadt, MD, a spokesperson for the Academy of Nutrition and Dietetics.

Their healthy protein content makes them a good option even if you're not one of the growing number of people going "flexitarian" or opting to eat less meat.

Here's your guide to making this legume a regular and great-tasting part of your diet.

Soy 101
All soy products are made from soybeans, mostly grown here in the United States. You can buy whole soybeans dried or canned, or in the produce section or freezer aisle as edamame, the common name for soybeans picked before they're fully mature. (Edamame can be purchased either in pods or shelled.)

Beyond whole beans, soy takes on a number of different guises. Roasted soybeans are sold as soy nuts or ground into soy nut butter. Soybeans can be soaked in water, cooked, and filtered to make soy milk and soy yogurt. Adding a coagulant to soy milk curdles it, producing tofu, which ranges in texture from "silken" (very soft) to "extra firm," depending on how much liquid is removed.

Soybeans can also be fermented into a paste called miso (the base for miso soup) or a cake or patty called tempeh, which is often used in place of meat in sandwiches or grilled and eaten on its own. Finally, soy can be found in many packaged foods — such as frozen meatless burgers, cereals, and energy bars — often in the form of "soy protein isolate," meaning it's mostly the protein from soybeans you're getting.

If all the mixed messages about soy products have you confused, you're not alone. Recent studies have certainly found mixed evidence on the benefits. I've been hearing mostly about soy's effect on heart disease and breast cancer, so here's the latest research on the topic.

Heart Disease
A recent comprehensive update of soy research by the American Heart Association's nutrition committee found that soy protein does not have as much of an effect on cholesterol as previously thought. The benefit for the heart is not due to a direct relationship to reduced cholesterol but rather because soy products are generally used as a substitute for unhealthy choices and also because they are low fat yet high in fiber, vitamins, and minerals.

Breast Cancer
Soy products contain a wide range of compounds including isoflavones, which can act as antioxidants, but also function as phytoestrogens. Phytoestrogens are chemicals that plants make that are similar to human estrogen, and many of us have read that these phytoestrogens have been linked to breast cancer. In some cases these phytoestrogens may be able to mimic estrogen in the body or block the action of estrogen. Phytoestrogens acting as estrogen could possibly affect cell communication, prevent the formation of tumors, or change the way DNA is processed in cell multiplication.

I've been a vegetarian for over 20 years, so tofu, tempeh, and seitan are always stocked in my fridge. If you're new to the meat-free world, preparing and eating these new foods can be really intimidating. I'm here to break down the basics so you know how to choose the right one for your nutritional needs and what to expect from your first bite.

Now that you know the nutritional stats, learn how these meat alternatives are made, what they taste like, and discover yummy recipes for preparing them after the break.

Soy is one of the most versatile ingredients; it can be eaten whole or ground, fermented, and formed into various ingredients for nutritious and healthy cooking. Not only that, but it's also high in protein and fiber and contains less fat than its animal counterparts, so it's a no-brainer for people who want to eat less meat. Want to know how different forms of soy compare in both taste and nutrition? Read on for four forms of soy and how they work in your diet!

• Edamame: Edamame are baby soy beans that are harvested when ripe and sold either frozen, cooked, or shelled. The nutty-flavored beans are great for snacking or in anything from stir fries to soups. A 1/2 cup of edamame has 95 calories, 4 grams of fat, 8.5 grams of protein, and 4 grams of fiber. Try shelled edamame in a super easy side like this brown rice and edamame dish.
• Soy milk: Soy milk is the liquid extracted from ground cooked soybeans. It also has a mild nutty flavor but can be sweetened with other flavors like vanilla as well as made into other dairy-like products like soy yogurt. A cup of plain soy milk has 100 calories, 4 grams of fat, 7 grams of protein, and 1 gram of fiber. Substitute soy milk for regular milk in anything from cereal to smoothies to pancakes (like these vegan pineapple pancakes with citrus cream).
• Tofu: Tofu is made by curdling soy milk with a coagulant to form thick white blocks. There are four types of tofu to use in various dishes: silken, soft, firm, and extra firm. Since tofu has little flavor, it works with many different kinds of dishes (it'll just take on the flavor of your ingredients). A 1/2 cup of tofu has 97 calories, 5.3 grams of fat, 10.1 grams of protein, and 0.5 grams of fiber. Firm and extra firm tofus are great in stir fries, or even healthier baked, like in this spicy mango veggie rice bowl.
• Tempeh: This form of soy is made by fermenting cooked soybeans with a mold. It is sold in dry, brown blocks and has a firm and chewy texture. A 1/2 cup of tempeh has 160 calories, 9 grams of fat, 15.4 grams of protein, and 3.5 grams of fiber. Many people think tempeh makes the perfect meat substitute, so try it out instead of bacon in a TLT — tempeh, lettuce, and tomato sandwich.

If you ever suffer from cramps, bloating, insomnia, breast tenderness, headaches, acne, or food cravings, your hormones may be in flux and need to be balanced. Hormones are crucial to our well-being since they impact our bodies at the cellular level and, if stabilized, many of the above symptoms can be alleviated.

According to The Biggest Loser trainer Jillian Michaels, the toxins in processed foods, nonorganic produce, prescription medicine, and the environment can throw our hormones out of whack, wreaking havoc on our systems. In her book Master Your Metabolism: The 3 Diet Secrets to Naturally Balancing Your Hormones For a Hot and Healthy Body!, Jillian talks about the important role our hormones play in our endocrine system and how we can rebalance them through diet, sleep, and exercise.

Reducing stress, drinking lots of water to flush out toxins, and getting your circadian rhythms on track are all steps in the right direction toward getting your hormones balanced out, but to learn about the easiest and most effective change you can make right now, just keep reading.

When I dabbled in vegetarian and veganism in college, I came to love tofu. It's so mild, so versatile, and such a healthy form of protein, that I continue to eat it regularly. When picking up a package of my favorite organic extra firm tofu from Nasoya, I saw a new label staring back at me — TofuPlus. It's fortified with vitamins B2, B6, B12, D, and calcium. I drink fortified soy milk, so I thought, "Why not fortified tofu?"

Sounds like a brilliant idea, but does it taste the same and have the same texture? To find out and see how it compares nutritionally to regular tofu read more
