People with certain digestive issues (IBS, Crohn's during flares), Oral Allergy Syndrome, specific allergies (lipid transfer proteins), those on Coumadin (due to Vitamin K), or anyone in vulnerable groups (elderly, young kids, immunocompromised) should be cautious or avoid lettuce, especially raw, due to foodborne illness risks and potential symptom triggers, notes Everyday Health. Cooking lettuce can reduce risks for some, but caution is needed with outbreaks.
While eating leafy greens won't pose problems for most people, some medical conditions may make digesting lettuce painful. "Gastrointestinal conditions that might make consumption of lettuce uncomfortable could include irritable bowel syndrome or an obstruction that may cause issues in general," says Sonpal.
Side-Effects & Allergies of Lettuce
Lettuce crops are sometimes sprayed with pesticides and hence it is advisable to wash the vegetable properly before consuming it. Consumption of lettuce may result in allergic reactions in some people. So it is better to check whether you are allergic or not before consumption.
Before eating, sort through your leaves and remove anything soggy, discolored, slimy or wilted, to be on the safe side. Avoid eating anything with an unpleasant or sour odor.
Symptoms of a lettuce allergy may include skin rashes, hives, itching, swelling, difficulty breathing, nausea, or anaphylaxis in severe cases. Always consult a doctor if you suspect a food allergy. What Is a Lettuce Allergy?
Norovirus, STEC, Campylobacter have highest leafy green illnesses and cost. Lettuces linked to over 75.7% of leafy green foodborne illnesses and 70% costs. Up to 9.2% of known pathogen-caused foodborne illnesses attributed to leafy greens.
If you are allergic to lettuce, a noticeable reaction, such as a red, itchy bump, will occur at the test site. Blood Tests: Blood tests, such as the RAST (Radioallergosorbent Test) or the ImmunoCAP test, measure the presence of specific IgE antibodies to lettuce proteins.
Other research suggests eating vitamin K-rich veggies like broccoli, spinach, lettuce, kale and cabbage dramatically reduces inflammatory markers in the blood.
Lettuce should be torn, not cut. Tearing breaks the cells along natural lines and helps keep it from wilting.
Perfect Times to Eat Salads for Maximum Health Benefits
Of all the lettuce diseases, downy mildew is one of the most restrictive, common and dangerous. It is a disease that can affect the plant at any stage of growth and has a very wide and prolonged window of incidence.

It also falls short in the nutrition department. That's because iceberg lettuce contains fewer vitamins and minerals than most dark leafy greens.
Leafy greens like lettuce are a common vehicle for foodborne illness, which can cause diarrhea. In fact, research shows that up to 9 percent of foodborne illnesses in the United States are attributed to leafy greens, with lettuce making up more than 75 percent of these cases.
Lettuce, like other foods, can be contaminated with germs that cause food poisoning. Many dishes are cooked before they're eaten, killing off most germs. But salads are usually eaten raw, increasing the chance you accidentally eat some hidden bacteria.
Change in the Appearance of the Stool
A Thin, narrow, or ribbon-like stool could indicate changes inside your colon. Color: Blood, darkened, or tarry (black) stool can signal issues inside the colon. Your doctor can help determine the cause.
Those who are prescribed a blood thinner, such as Coumadin, are told to avoid foods high in Vitamin K because this will counteract the effects of the blood thinner. Leafy vegetables (e.g. kale, collards, turnip greens, swiss chard, salad greens, parsley, spinach) are the highest sources of vitamin K.
If even a few leaves look damaged, slimy, or bruised, don't eat any of the greens in that package.
Wash produce before prepping or chopping it. For compact leafy greens, like romaine lettuce, peel the leaves apart before washing and wash the leaves separately to make sure dirt and bacteria aren't trapped under leaves. When washing, separate different types of vegetables from one another to avoid cross contamination.
Infections like E. coli and other unsafe bacteria are easily avoided by properly washing your greens. And especially if you're getting your lettuce from a garden or local farm, you'll want to make sure you rinse out any possible dirt (where bacteria often hides) or bugs that you don't want in your salad.
Some people with arthritis swear that nightshade vegetables — such as tomatoes, potatoes, eggplants, and peppers — cause their arthritis to flare. While there aren't any studies to support a link between arthritis pain and most nightshades, tomatoes may be an exception. That's because they raise levels of uric acid.

They may present locally to the skin (contact urticaria or dermatitis), the oropharynx (oral allergy syndrome), the gastrointestinal tract (abdominal pain, vomiting, diarrhea), or become more generalized with cardio-respiratory compromise (anaphylaxis) [9].
These eight foods account for 90 percent of food allergic reactions. They are milk, eggs, fish (such as bass, flounder, cod), crustacean shellfish (such as crab, lobster, shrimp), tree nuts (such as almonds, walnuts, pecans), peanuts, wheat and soybeans.
The most common food allergy symptoms include:
