A plant-based diet is so good for you. Vegetarians consume less saturated fat and cholesterol and more fiber and phytochemicals than standard diet followers. Add positive links between veg-based diets and lower levels of diabetes, obesity and more, and you’ve got a way of eating worth cheering for.

According to the American Dietetic Association (ADA), "appropriately planned vegetarian diets are healthful, nutritionally adequate and provide health benefits in the prevention and treatment of certain diseases" through all stages of life, from pregnancy to infancy, and through childhood and adolescence.
The key here is "appropriately planned." Its true: Potato chips, white rice and mac and cheese are vegetarian, but if these and other refined foods make up the majority of your diet, you won't get the nutrients you need. Even if you eat nothing but the healthiest vegetarian foods, you still need to be careful that you're getting enough nutrients and calories – and in the proper balance. For instance, fiber (plentiful in plant-based foods) is beneficial, but too much of it can interfere with mineral absorption.
So how do you achieve a nutritionally adequate, optimally healthful vegetarian diet? With careful planning and forethought. Use the info below as a guide to getting adequate nutrients, but always be sure to consult your doctor or nutritionist for advice.
Most people require about 0.8 grams of protein per kilogram of body weight, or about 58 grams of protein per day for a 160-pound adult. Vegetarians and vegans may need to eat 10–20% more protein than recommended in order to compensate for the lower digestibility of plant-based protein.

The Recommended Daily Allowance (RDA) of iron for vegetarians and vegans is 1.8 times higher than for non-vegans: 27mg. versus 15mg. This is because iron from plant foods is not as available to the body as iron from animal sources. Although iron intake and stores are usually adequate in vegetarians and vegans, young and pregnant women and athletes should pay special attention to make sure their needs are met.
Essential fatty acids are aptly named because they are truly essential to health. Since the body does not manufacture them, they must be obtained from the diet. Omega-3's are one class of essential fatty acids that are important for maintaining cell membranes, including those of the brain and eyes, and for regulating bodily processes.
** To achieve a balanced Omega-6/Omega-3 ratio, decrease intake of certain vegetable oils including corn, soy and grapeseed oils. **
It is challenging to maintain adequate levels of vitamin B12 on a primarily plant-based diet. Because low levels of this vitamin increase disease risk and can negate the positive cardiovascular effects of a vegetarian or vegan diet, supplementation with vitamin B12 is strongly recommended. This is especially true for pregnant and lactating women for whom optimum vitamin B12 intake is crucial.
Calcium is essential for overall body health, helping to ensure proper muscle and nerve function as well as strong bones and teeth. Vegetarians and vegans are most likely to have calcium levels lower than the general population along with the lower bone density that implies. (Inadequate dietary protein can also contribute to low bone density.)
Calcium levels can be negatively affected by other dietary factors such as high sodium consumption, too much or too little protein, caffeine and soft drinks with phosphoric acid, so be sure to be aware of these, as well.
If you're a vegetarian or vegan who spends a lot of time indoors or live in a northern clime, chances are you have less-than-optimal vitamin D levels. Sufficient vitamin D can be produced by exposure to the sun during warm months: 10–15 minutes on face and forearms for people with fairer complexion or 30 minutes to 3 hours for people with darker complexions. During cold months, you will likely have to depend on fortified foods or supplements.
Plant foods tend to be lower in zinc concentrations than animal foods. In addition, the bioavailability of plant-based zinc is lower than from animal products. Marginal deficiencies in zinc may be common in vegetarians, especially if they consume a lot of wheat bran and soy, as well as tea, chocolate and coffee. (These foods are high in phytates, which interfere with zinc absorption.)
Increase the bioavailability of zinc by soaking and sprouting grains, seeds, nuts and legumes, by leavening breads with yeast and sourdough and by fermenting foods.
Iodine is an essential mineral required for good thyroid function. Too little or too much iodine in the diet can lead to hypothyroidism, a precursor to disease. Vegetarians and vegans generally consume less iodine than the general population, but this varies depending on their intake of supplements, iodized salt, and seaweeds. Vegetarians and vegans who do not consume iodized salt may be at risk for iodine deficiency.
Animal-derived ingredients abound in supplements, and vegetarians must be alert to avoid them. The best way to make sure you're not ingesting animal products along with your supplements is to become an avid label reader and consult the knowledgeable Team Members in our Whole Body department. Here are some things to look out for:
Some of the above products have vegetarian-friendly alternatives but they are not as widely available because they cost more to produce. Many quality supplements sold at conscientious health or natural food stores announce their vegetarian or vegan status on the label. If it doesn't say it on the label, you can assume that it is not veggie friendly.
To educate yourself further about specific products, ask a Whole Body Team Member for the manufacturer's contact information. Asking questions helps companies understand the importance of this issue.
Whole Foods Market is committed to carrying the highest quality nutritional supplements available. We strive to offer vegetarian-derived products whenever possible and to ensure that all products are labeled accurately.
