Are Nightshade Vegetables Bad For Arthritis

The Health Benefits Of Nightshades

If I Have Arthritis, Should I Avoid the Nightshade Foods? Dr.Berg

And in fact, Waldron points out, many of the foods that fall under the nightshade designation which include not only vegetables but also spices like cayenne and paprika are typically rich in nutrients and antioxidants that have been shown to fight inflammation.

In addition, many nightshades offer a host of other nutritional benefits, says nutritionist Julie Upton, RD, cofounder of Appetite for Health. Here are just a few of the more commonly consumed nightshade vegetables and the perks you could be missing out on if you avoid them:

Eggplant: Like other dark-colored produce, the eggplants deep purple skin is an indicator of beneficial phytonutrients. The flesh is rich in fiber and provides a good dose of potassium and magnesium, two minerals that help with muscle and nerve function.

Tomatoes: Although best known as a top source of lycopene, an antioxidant that has been shown to help protect against cardiovascular disease and certain cancers, tomatoes are also an excellent source of vitamins C and K and beta carotene, which your body needs to make vitamin A.

Potatoes: Spuds get a bad rap as carbs, but theyre really nutritional all stars. At just around 100 calories, a medium Idaho potato has four grams of filling fiber and is high in blood pressure-lowering potassium, along with many other B-vitamins and trace minerals.

The Case For Eating Nightshade Vegetables

Criticism of nightshades is mostly unwarranted.

In fact, nightshades have many health benefits. For example:

  • Tomatoes contain tomatine, a glycoalkaloid thats been shown to lower LDL cholesterol and reduce plaque in the arteries. Some studies suggest it may also inhibit cancer cell growth .
  • Glycoalkaloids in purple potatoes may slow the growth rate of cancer cells .
  • Capsaicin in peppers increases satiety and may help with weight loss among those with obesity .
  • Eggplant is high in anthocyanin, which lowers risk for hypertension and coronary artery disease .
  • Potatoes in general are nutrient-dense, filling, and cheap to buy.

In general, nightshades are high in fiber and antioxidants too.

Most people already fall far short of the recommended minimum 5 servings of vegetables per day. Eliminating these key foods in the diet may make it even more difficult to reach this goal and cause more harm than good in otherwise healthy people.

Summary: Nightshades are high in fiber, antioxidants and other beneficial compounds. They do much more good than harm in the diet.

Side Effects Of Eating Nightshades

Unless youre intolerant to nightshades, you generally wont have any side effects from eating them.

If you are sensitive to nightshades, reactions often result in inflammation, which has a big impact on people with certain kinds of arthritis. It may take up to a day or two to occur. Stomach and digestive symptoms may also occur.

Myth: Nightshade Vegetables Worsen Arthritis Pain

Anti Diet

Much of the online discussion concerns nightshade vegetables and arthritis, and the notion that eating these vegetables causes an increase in pain or inflammation. But no scientific evidence supports that theory. Im not aware of any studies in peer-reviewed journals that prove or disprove that they affect arthritis, says arthritis expert Mark Erwin, an assistant professor of orthopedic surgery at the University of Toronto. There are a lot of references to it, but the evidence is mostly anecdotal. Theres also no scientific reason to avoid nightshades even if you have arthritis, says Pamela Piotrowski, a registered dietitian at the Arthritis Society of Ontario. Many people have food intolerances. If you start to feel achy every time you eat tomatoes, then maybe, for you, tomatoes are a contributing factor. But even if your symptoms disappear after eliminating tomatoes, it would be hard to pinpoint that as the cause since many factors can affect arthritis.

Do Nightshades Worsen Functional Digestive Symptoms

are those that cause symptoms without a clear medical cause.

Theyre not immediately dangerous but can significantly affect quality of life.

Examples include irritable bowel syndrome , bloating and heartburn.

Specific foods are known to trigger functional digestive symptoms. Elimination diets, like the low FODMAP diet, have shown great promise in relieving discomfort.

Nightshades are commonly reported to worsen IBS symptoms, but it would only be certain varieties, and only because of FODMAPs. Regular potatoes and tomatoes, for example, would have little impact.

Additionally, many reported nightshade chemicals do not always make IBS symptoms worse. Capsaicin has actually shown potential to dull pain receptors in the gut, improving pain symptoms.

In one small study, IBS patients who received red pepper powder in capsule form showed significant improvements in abdominal pain and bloating after 6 weeks of treatment .

But several of the volunteers either dropped out of the study or needed to adjust the dose due to abdominal pain. This suggests that not all with IBS tolerate red pepper powder, or that the dose should be individualized.

In other studies, capsaicin had very little effect either positive or negative .

These research conflicts suggest that diet should be individualized. Some with functional digestive symptoms may be sensitive to nightshades, while others may tolerate them well.

Is There A Link Between Nightshade Vegetables And Inflammation

Some people feel that eating foods from the nightshade family, also known as solanaceous vegetables, may make their arthritis worse. But research has shown that there is no link between inflammation and solanaceous vegetables.

The Difference Between Nightshade Fruits And Vegetables

Nightshade Veggies: Good or Bad?

Tomatoes are often thought of as being in the vegetable family due to their savory flavor, but they are actually a fruit. Fruit is an edible part of a plant that develops from a flower and contains seeds. Peppers and eggplant are also technically nightshade fruits.

Vegetables are any other edible part of a plant, like the roots, stems, or leaves. Potatoes are a nightshade vegetable, not a fruit.

Whatever you choose to do, its important to strike a balance between medication and lifestyle changes.

Myth: They Cause Migraines

Linking nightshades to migraines is also without merit, according to Dr. Jonathan Gladstone, director of the Gladstone Headache Clinic and director of neurology at Cleveland Clinic Canada in Toronto. I am certain that headache experts internationally would be in agreement that there is no evidence that tomatoes, peppers, eggplant and potatoes cause migraines, he says.

The health benefits of nightshade vegetables far outweigh any risks, says Piotrowski. Tomatoes and peppers are amazing sources of antioxidants that lower the risk of cancer and heart disease potatoes are high in vitamin C and eggplant is a source of vitamin K. All are high in fibre. If you do want to eliminate them, make sure you get this nutritional value from other foods.

Tom had already been seen by multiple rheumatologists, and had been prescribed AZT, the immune suppressive drug called Azathiaprine. However, this drug was not helping his arthritis. Instead, it was causing severe muscle weakness, a well known adverse effect of the AZT drug which is a mitochondrial toxin.

On examination, Toms hands and knee joints were visibly swollen, and tender with active inflammation. He was able to walk and to get up from a sitting position with difficulty, indicating muscle weakness from the AZT drug.

Dietitian Sheds Light On Nightshade Vegetables

If youve been hearing about nightshades in conversations about a healthy diet, you may be left wondering whether these plants are actually beneficial for you.

The most common edible nightshades are the tomato, potato, eggplant, bell pepper and chili pepper. Some diets claim that nightshades are inflammatory and should be avoided. This idea is rooted in the fact that nightshades are a large family of plants that contain a chemical compound called alkaloids. In extremely high doses, some alkaloids can make inflammation worse or be poisonous. Fortunately, thats not the case for the edible nightshades youre picking up in the produce aisle.

The nightshade foods are very nutritious, available at the grocery store and easy for people to use to prepare a healthy meal, says Athena Nofziger, a dietitian for the Samaritan Cancer Program, who counsels patients during and after cancer treatment about healthy diet choices.

Are They Harmful For People With Autoimmune Diseases

Although nightshade vegetables are a rich source of nutrients, many people claim theyre harmful and should be avoided.

The majority of these claims seem to center around a group of substances found in nightshades called alkaloids.

Alkaloids are nitrogen-containing substances typically found in the leaves and stems of nightshades. Theyre often very bitter and function as a natural insect repellent.

But the edible portions of these plants contain some alkaloids, too. Consequently, many people with autoimmune diseases eliminate nightshades from their diets, believing they contribute to their health problems.

However, research has yet to show that nightshade vegetables contribute to autoimmune diseases.
