The Advantages of a Vegetarian Diet

Of course, there are all sorts of healthy diets you can try. And one of the most common ones is the vegetarian diet VSports手机版. Registered dietitian Nickie Kaetzel, MS, RDN, LD, explains what this is — and what the benefits are.

What is a vegetarian diet?

Keeping a vegetarian diet — which some people call a vegetarian eating pattern — means you eat plant-based foods V体育安卓版. This includes foods like:.

• Fruits.
• Vegetables.
• Legumes.
• Nuts and seeds.

The types of vegetarian diets

But not all vegetarian eating habits are the same V体育ios版. Some vegetarian diets exclude only meat, poultry and fish, while others also exclude eggs and dairy products.

The three main types of vegetarian diets are vegan, lacto-vegetarian and lacto-ovo-vegetarian.

Vegan

This diet excludes all animal products, meaning any food that comes from an animal. That category encompasses foods like beef and chicken or less obvious byproducts, such as eggs and honey. Overall, a vegan diet does not include: V体育平台登录.

• Meat, like beef and pork.
• Poultry.
• Fish.
• Eggs.
• Dairy.
• Honey.

You might be surprised at how many foods contain animal products. For example, certain kinds of beer contain isinglass, which is derived from fish bladders. Technically, that means this beer isn’t vegan VSports注册入口.

Lacto-vegetarian

This diet includes dairy products, but excludes foods like:

• Meat.
• Poultry.
• Fish.
• Eggs.

Lacto-ovo-vegetarian

The majority of vegetarians in America fall into this category VSports在线直播. This diet includes eggs and dairy products, but excludes:.

• Meat.
• Poultry.
• Fish.

Health benefits of a vegetarian diet

A vegetarian diet offers many potential health benefits.

Choosing vegetarian foods to get the nutrients you need — instead of relying on animal-based food — eliminates much of the saturated fat and cholesterol found in a meat-based diet.

Kaetzel notes that a vegetarian diet can help lower your cholesterol and blood pressure levels and reduce your intake of calories. And these changes can reduce your risk of having obesity, heart disease, hypertension, diabetes and possibly cancer VSports app下载.

How vegetarians can eat proteins, calcium and iron

"VSports app下载" Protein

There are many non-animal sources of protein. Although it was once thought that vegetarians had to combine certain foods to get a complete protein, Kaetzel says that’s no longer the case V体育官网. Foods rich in protein include:.

• Nuts.
• Seeds.
• Legumes (beans).
• Lentils.
• Tempeh.
• Whole grains, like oatmeal, 100% whole-wheat breads and 100% whole-wheat cereals.
• A variety of prepared wheat gluten (the protein portion of wheat) foods, like seitan.

Soy

Soy is another excellent source of protein. Examples of soy products include:

• Soybeans.
• Soy milk.
• Tofu.
• Tempeh.
• Soy pasta.
• Prepared soy products.

Calcium

Lacto-vegetarians and lacto-ovo-vegetarians can eat dairy products rich in calcium. Calcium-rich choices for vegans include:

• Dark, leafy greens.
• Bok choy.
• Kale.
• Broccoli.
• Tofu made with calcium.
• Calcium-fortified nondairy milk alternatives.
• Almonds.
• Blackstrap molasses.
• Calcium-fortified cereals and juices.
• Cornmeal products treated with lime (calcium hydroxide), such as corn tortillas.

Iron

Good sources of non-heme iron (the type of iron found in plant foods) include:

• Dark, leafy greens.
• Dried legumes (beans) and lentils.
• Soybeans.
• Blackstrap molasses.
• Spinach.

Risks of a vegetarian diet

Vitamin D deficiency

Few foods are naturally high in vitamin D, and many of the ones that are (like salmon or trout) aren’t vegan.

That means vegans need to be more intentional about what they eat. For example, vegan sources of vitamin D include mushrooms, as well as fortified vegan milks, juices and cereals.

Vegans can also get vitamin D (also known as calciferol) by taking a vegan supplement with food. Vitamin D2 (ergocalciferol) is always vegan and some vitamin D3 is vegan from lichen.

Experts recommend adults aged 19 to 70 take 600 IU of vitamin D daily, while those over 70 years old take 800 IU. But you might require a different dose of supplementation, so be sure to check with your doctor before adding any supplements to your diet.

You can also spend 20 minutes in directed (unprotected) midday sunlight to get vitamin D.

But sun exposure is unreliable. The season, time of day, angle of the sun, amount of cloud coverage or smog, skin melanin content and sunscreen can all affect vitamin D synthesis. Supplements are a consistent source of vitamin D.

Because vitamin D is added to milk, vegetarians who drink milk aren’t at high risk of becoming deficient.

Vitamin B12 deficiency

Vitamin B12 is the only vitamin not present in plant foods. That means vegans won’t get enough of this nutrient.

Good sources of vitamin B12 are fortified cereals, nondairy milks and vegan supplements. Nutritional yeast is another good source that has a pleasantly cheesy flavor and can be used as a cheese substitute in recipes.

Lacto-vegetarians and lacto-ovo vegetarians who eat dairy and eggs are less likely to develop a B12 deficiency.

But experts recommend that vegetarians age 50 or older take a B12 supplement. Our bodies don’t efficiently absorb dietary sources of vitamin B12 after that age. But again, as with any supplement, Kaetzel advises you to ask your doctor or dietitian about taking vitamin B12 supplements before you start.

An unbalanced diet

It’s important that any vegetarian or vegan diet is balanced.

A vegetarian diet should offer the right amounts of:

• Carbohydrates.
• Protein.
• Fat.
• Fiber.
• Vitamins.
• Minerals.

A vegetarian diet can offer many health benefits, but because balance is so important, Kaetzel recommends meeting with a healthcare provider or a registered dietitian before starting a vegetarian diet to see what’s right for you.
