Are plant-based diets healthy?

Plant based healthy small

When I went vegan in 2000, health wasn’t one of the reasons why I made the decision to stop eating animals, but it’s become more of a motivating factor over the years.

Since being diagnosed with Crohn’s Disease in 2008, my diet has changed dramatically from a “junk food vegan” to a more whole-food approach. It includes more and more of the foods that research has been showing to offer positive health benefits to humans.

Foods like soy, whole grains, legumes, dark leafy greens and a variety of fruits and vegetables are the staples in my diet. Add in a few key nutrients like vitamin B12, vitamin D and DHA (partly because of Crohn’s and partly because I don’t eat many fortified foods) and you’ve got a diet that science has been found to offer disease prevention, longevity and long-term health benefits.

Vegan diets, for one reason or another, are always assumed to be lacking in protein, calcium or iron, but I think it’s important to understand that any diet that isn’t appropriately planned will be doomed to fail, which is why I think it’s awesome that there are so many resources out there to help anyone get started on a well-planned, healthy, plant-based diet regardless of age, gender or circumstances.

There are nutritionally balanced meal plans that are easy to follow and delicious; I list several of the resources which offer these plans on my Vegan Resources page.

As more of the scientific literature validates the benefits of plant-based diets, high-profile charities, hospitals, universities, government policy groups, and even health insurance companies are showing their support or even recommending plant-based diets.

This is exciting to see, and even more so because it’s happening in a world dominated by industry lobbyist groups pushing for animal products to be in every facet of our lives.

Below you’ll find a (short list) of organizations and health agencies that support plant-based diets.
Feel free to share this with anyone who has doubts over the nutritional adequacy of a plant-based (vegan) diet.

The Cleveland Clinic (one of the top GI and IBD hospitals in the USA) says:
“There really are no disadvantages to a herbivorous diet! A plant-based diet has many health benefits, including lowering the risk for heart disease, hypertension, Type 2 diabetes, and cancer. It can also help lower cholesterol and blood pressure levels, plus maintain weight and bone health….” and “…If a vegetarian diet is well-planned and balanced, it can be just as nutritious, if not more beneficial to health, than a traditional diet.” SOURCE

The USDA states that:
“Vegetarian diets can meet all the recommendations for nutrients.” SOURCE

The University of Pennsylvania Health System writes that:
“A well-planned vegetarian diet can give you good nutrition. A vegetarian diet often helps you have better health. ” SOURCE (Resource moved after site change; cached page)

The Mayo Clinic (another top GI and IBD hospital) says:
“A well-planned vegetarian diet can meet the needs of people of all ages, including children, teenagers, and pregnant or breastfeeding women. ” SOURCE

Kaiser Permanente (a huge health insurance provider in the US) says:
“Physicians should consider recommending a plant-based diet to all their patients” SOURCE

The American Diabetes Association says:
“A vegetarian diet is a healthy option, even if you have diabetes. Research supports that following this type of diet can help prevent and manage diabetes. ” SOURCE

The Dietitians of Canada state that:
“A healthy vegan diet has many health benefits including lower rates of obesity, heart disease, high blood pressure, high blood cholesterol, type 2 diabetes and certain types of cancer.” SOURCE

The British Dietetic Association says this:
“Well planned vegetarian diets can be both nutritious and healthy. They have been associated with lower risks of heart disease, type 2 diabetes, obesity, certain types of cancer and lower blood cholesterol levels.” SOURCE

The Dietitians Association of Australia says that:
“…with good planning it is still possible to obtain all the nutrients required for good health on a vegan diet.”  SOURCE

The Canadian Heart and Stroke Foundation says:
“Vegetarian diets can provide all the nutrients you need at any age, as well as some additional health benefits.” SOURCE

The FAO (Food and Agriculture Organization of the United Nations) states:
“…it is clear that meat is not essential in the diet, as witness the large number of vegetarians who have a nutritionally adequate diet…” SOURCE

The Academy of Nutrition and Dietetics (formerly the American Dietetics Association) states:
“… appropriately planned vegetarian diets, including total vegetarian or vegan diets, are healthful, nutritionally adequate, and may provide health benefits in the prevention and treatment of certain diseases. Well-planned vegetarian diets are appropriate for individuals during all stages of the life cycle, including pregnancy, lactation, infancy, childhood, and adolescence, and for athletes.” SOURCE (updated Dec 2016)

The National Institutes of Health (via MedlinePlus) states:
“People who follow vegetarian diets can get all the nutrients they need.” SOURCE

The American Heart Association states:
“Vegetarian diets can be healthful and nutritionally sound if they’re carefully planned to include essential nutrients.” SOURCE

The National Health Service (NHS) states: “With good planning and an understanding of what makes up a healthy, balanced vegan diet, you can get all the nutrients your body needs.” SOURCE

Question: Know of any other groups that I should add to the list?

  1. I am really enjoying reading all the information I can get lately on Vitamins and what foods supply what in our diets. I have found that I am doing all the right things, but my guts are not. Dealing with malabsorption for the last year or so. Dona and Eric have answered a lot of my questions on Vit.D’s and the article Dona was perfect. They talk about the malabsorption of Inflammatory Bowel Disease, Chrohns and other issues. I am now confident that I am doing all the right things, but my guts fail the test horribly. I now have Severe Anemia, Low Blood Pressure, Malabsorption has been proven, and I likely need my valves replaced in my heart. But the Anemia and malabsorption trumps heart repair. Just knowing that I am eating as right as possible is good right now. Iron Infusions in B.C. cost $131.50 each. I live on less then 1400. a month. I pay bills and rent. Do the math. I had to find out what foods are high in Iron and make sure I am eating them. Turns out I defiantly am eating right all along. This article today confirms so much more. Thank you for bringing this up. Malabsorption is no picnic. I noticed things at first that I want to make you all aware of because you too deal with bowel disease also.  The first signs off malabsorption was hair loss, fatigue. Similar to Thyroid issues I was already dealing with. Then the fatigue increased, skin became dry and nails brittle. I noticed fats floating in the toilet water after emptying my pouch. There were a whole sort of other changes and I kept track of them in a journal. I took it to the doctor after the first ten pounds dropped off of me. I stopped keeping track after fourty pounds because the signs were the very same only more of them. Clothes that always fit, stopped fitting, but I kept wearing the clothes I had. My feet hurt. There is no fat left on my feet to make it comfy for walking. Blisters explained ill fitting shoes. My eyes won’t always focus. Long story short, 55 lbs. later, I was holding at 140. I dropped below that now. I am 5’6″ with larger bones then most women.  Last time this happened I weighed 92 lbs. when I was released from the hospital, they could no longer help me. I recovered. Then, 12 years ago, they admitted me at 140. I was on TPN, Total Peritoneal Nutrition for almost a year. The Banana bag IV. Now the anemia. I have been told that in order to be this continually anemic, I am bleeding from somewhere but they can’t find it. Hopefully the CT Scan on Friday will tell them this.  I look like I am anorexic and people always do the double take  at me when I am in public. People, eat, and eat well. That extra 40 lbs. I had on me meant to me, that I was healthy. My doctor did the body mass index thing and said I was obese. I was 182 lbs. Not anymore. Eat yourselves healthy. Make sure you are getting what you need and pay attention to those suttle signs our bodies give us. If in doubt, check it out. Because I have been here, done this before, I new I was in trouble again. Tho I was hoping I was wrong.

  2. Hi Tony,Read this:  https://ods.od.nih.gov/factsheets/VitaminD-HealthProfessional/ Lots of good info on Vitamin D…and even a section on absorption by people with IBD etc…Looks like some sunlight might help. I take a small supplement .. ( too much can be bad for you..be aware).Looks like mushrooms are a good source of D ( chew them well/cook them). Interesting factoid about mushrooms.. leave them in the sun for awhile before you cook them and they will have more vitamin D.I’m sure Eric knows more about this.Wool? Don’t know about that ( Except that  its is the title of an excellent scifi novel by Hugh Howey).

  3. Hi Eric, I’m curious.  It was my understanding that vitamin D3 is critical to human health but that it is missing from a vegan diet as it comes from wool. Is this true. If so, do you compensate for the loss of vitamin D3 from your diet? If so, how?

      Hi Eric,

       

      I’m curious.  It was my understanding that vitamin D3 is critical to human health but that it is missing from a vegan diet as it comes from wool. Is this true. If so, do you compensate for the loss of vitamin D3 from your diet? If so, how?

      That’s actually a good question and a valid concern. 

      There are actually two kinds of Vitamin D – d2 and d3. Vitamin D3 is more commonly found in animal products, however, it can also be synthesized through lichens or mushrooms. Commercially, there are actually quite a few vegan versions of D3 that can be purchased nearly everywhere, including Amazon.

      Both D2 and D3 are used and prescribed by doctors. D3 tends to be preferred, but that depends on the dose, status of the person taking it, frequency taken, etc. 

      I’ve used both vegan d2 (this is always vegan) and vegan d3 with success. However, the “best" way to get vitamin D is through natural sunlight – which is not without risks, so supplementation is universally recommended for all ages. 

      On a practical note, many foods are fortified with Vitamin D, including dairy and non-dairy products. I know that many kinds of cereal are now being fortified with vitamin D, although it tends to be the non-vegan version, so I’m always cautious when shopping. Plant-based, non-dairy milks always use D2.
