DEAR MAYO CLINIC: A pal of mine continues to talk extremely in regards to the well being advantages of a diet the place individuals get rid of lectins. She says it helped her shed some pounds and lowered her arthritis ache. What are lectins, and might a lectin-free diet treatment autoimmune ailments and stop different well being issues?
ANSWER: Lectins are naturally occurring proteins which are present in all meals, however they’re most concentrated in sure vegetation. Lectins serve a protecting perform for vegetation as they develop. They wouldn’t have dietary worth when consumed in meals.
Foods that comprise excessive quantities of lectins embrace legumes, comparable to beans, lentils, peas and peanuts, in addition to tomatoes, potatoes, eggplant, sure fruits, wheat and different grains.
While your diet can affect the best way you are feeling, particularly you probably have a persistent situation, you will need to concentrate on how elimination diets can negatively have an effect on the physique. This is especially essential if you’re already on a restrictive diet.
Grains and legumes are a powerhouse of vitamins. They are wealthy in B nutritional vitamins, iron and fiber. These vitamins might be troublesome to get if you’re, say, gluten-free.
Despite many claims, no scientific proof exhibits that eliminating dietary lectins will treatment any medical issues or circumstances, together with autoimmune ailments. Your pal could credit score her weight reduction success and higher well being to her diet, however I’d query if she additionally eradicated different issues which will have been contributing, comparable to limiting sugar, processed meals and extra salt.
Some analysis appears to point taking in giant portions of uncooked lectins might negatively have an effect on well being. But the quantity you’d have to eat day by day to get to that stage is way greater than a typical diet would come with. And different research have proven that lectins break down when processed or cooked, so the chance of adversarial well being results arising from lectin-rich meals that aren’t uncooked is just not trigger for concern.
In addition, most meals that comprise lectins are really helpful as a part of a wholesome, well-balanced diet. A big physique of scientific proof clearly helps the advantages of a diet wealthy in fruits, greens, complete grains, and nuts and seeds.
The well being advantages you obtain from together with these meals in your diet outweigh any perceived advantages from avoiding meals with lectins. With that in thoughts, a diet that avoids lectins is just not one most dietitians would usually advocate.
If you could have a medical concern triggering signs that appear to be associated to the meals you eat, converse to your major care supplier about having a session with a dietitian. Likewise, if you’re merely consuming a diet that features a number of meals and also you’re having signs that make you are feeling unwell, it typically might be troublesome to pinpoint the precise supply of the issue by yourself. It could possibly be a meals allergy or a meals intolerance, or it will not be associated to your diet in any respect.
Thus, you will need to converse to your well being care skilled to evaluation and type out the reason for your signs. Some medical facilities have dietitians who specialise in gastrointestinal points, and people professionals may also help in these circumstances. Take time to talk with a well being care skilled who can evaluation your diet and provide ideas for modifying it in a manner which will ease your signs.
A dietitian could advocate, for instance, a short-term elimination diet, excluding sure classes of meals that are inclined to trigger allergic reactions most frequently. Once these meals have been taken out of a diet, then they’ll rigorously be reintroduced to determine potential causes of food-related signs. Based on that or different evaluations, a dietitian could make suggestions that match the scenario.
Rather than utilizing a generalized strategy and making an attempt to use it to everybody—comparable to avoiding all meals with lectins—a diet that is structured and overseen by a dietitian and based mostly on scientific proof might be custom-made to accommodate a particular person’s sensitivities. That sort of systematic strategy usually yields higher long-term outcomes than simply avoiding a sure sort of meals or a meals ingredient and hoping to really feel higher.
