| Butter beans are always larger than lima beans in every store. | Size is a regional label, not a rule; small lima beans are often sold as butter beans in the southern United States. |
| Fresh lima beans and dried lima beans cook in the same amount of time. | Dried lima beans require soaking and 45-60 minutes of simmering, while fresh lima beans cook in just 15-20 minutes. |
| Butter beans get their name from being cooked with actual butter. | Butter beans are named for their creamy, buttery texture and rich flavor, not for any butter in the recipe. |
| Raw lima beans are perfectly safe to eat straight from the pod. | Raw lima beans contain linamarin, a cyanogenic compound, so they must be boiled thoroughly to become safe for consumption. |
| Frozen lima beans and canned lima beans have identical nutritional value. | Canned lima beans often contain added sodium, while frozen lima beans typically have less salt and retain more of their natural vitamins. |
| Baby lima beans are a young version of a completely different bean. | Baby lima beans are simply smaller, younger seeds of the same Phaseolus lunatus species that produces standard lima beans. |
| Butter beans are a type of white bean like cannellini or navy beans. | Butter beans belong to the Phaseolus lunatus species, while cannellini and navy beans are from the Phaseolus vulgaris species. |
| You must soak lima beans overnight or they will never soften properly. | A quick hot-soak method works fine; boiling water over dried lima beans for one hour achieves the same softening result. |
| Green lima beans and white lima beans come from different plants entirely. | Green and white lima beans are just different maturity stages or cultivars of the same Phaseolus lunatus plant species. |
| Butter beans are a rare gourmet item that is hard to find in normal grocery stores. | Butter beans are widely available in most American supermarkets, especially in canned and frozen forms in the vegetable aisle. |
| Lima beans are a vegetable that counts toward your daily vegetable servings. | Lima beans are legumes, so they count toward the protein group, not the vegetable group, in official dietary guidelines. |
| Eating lima beans raw is safe if you only eat a very small amount. | Even small amounts of raw lima beans can cause cyanide poisoning symptoms, so boiling them is always the mandatory safety step. |
| Butter beans and lima beans have completely different flavors that experts can easily detect. | Butter beans and lima beans taste identical because they are the same bean, so no expert can tell them apart by flavor alone. |
| Lima beans originated in Europe and were brought to the Americas by explorers. | Lima beans originated in the Andes region of South America and were cultivated there thousands of years before European contact. |
| Butter beans contain almost no protein, making them a poor meat substitute. | Butter beans provide about 15 grams of protein per cooked cup, making them an excellent plant-based protein source for meals. |
| You cannot eat lima beans if you are following a low-carb or keto diet. | One cup of cooked lima beans has about 39 grams of carbs, so they are too high in carbs for strict keto dieters to consume. |
| Lima beans and edamame are the same bean sold under different marketing names. | Lima beans are Phaseolus lunatus, while edamame are immature soybeans from the Glycine max species, so they are unrelated plants. |
| Butter beans are a modern hybrid created by scientists in a laboratory. | Butter beans are an ancient heirloom crop with archaeological evidence of cultivation in Peru dating back over 8,000 years. |
| All lima beans are pale green, and any white bean labeled lima is a mislabel. | Lima beans come in many colors including white, cream, green, red, and speckled varieties depending on the specific cultivar grown. |
| Cooking lima beans in a slow cooker is always the safest and most reliable method. | Slow cookers may not reach boiling temperatures, so lima beans should be boiled separately first to destroy the cyanogenic compounds safely. |
| Butter beans are naturally sweeter than lima beans because they contain more sugar. | Butter beans and lima beans have identical sugar content because they are the same species with the same nutritional profile. |
| Lima beans were named after the city of Lima, Ohio, where they were first grown commercially. | Lima beans are named after Lima, Peru, the capital city near the region where Spanish explorers first encountered this bean species. |
| Frozen butter beans have already been cooked, so you can eat them straight from the bag. | Frozen butter beans are raw and blanched only, so you must cook them thoroughly before eating to ensure they are safe. |
| Butter beans are gluten-free, but lima beans contain a small amount of gluten protein. | Both butter beans and lima beans are naturally gluten-free because they are the same legume species with no wheat proteins at all. |
| Lima beans are too starchy to be considered a healthy food choice for most people. | Lima beans are nutrient-dense, providing fiber, folate, magnesium, and potassium, making them a heart-healthy addition to balanced diets. |
| The green lima beans are immature, while the white ones are fully mature seeds. | Green lima beans are an immature stage, but white varieties are mature cultivars, so color alone does not determine the maturity level. |
| Butter beans cannot be grown in home gardens because they require tropical conditions only. | Butter beans grow well in temperate home gardens with warm summers, and they mature in about 65 to 80 days after planting. |
| Lima beans cause severe gas, so people with sensitive stomachs must avoid them completely. | Soaking dried lima beans and discarding the water reduces raffinose sugars, which significantly lowers gas production for most sensitive individuals. |
| Butter beans are a completely different food from lima beans, so recipes cannot be swapped. | Butter beans and lima beans are interchangeable in any recipe because they are the same bean species with identical cooking properties. |
