Lima beans: the bean most trials tested by proxy

Almost nothing on this page was measured in a lima bean. The strongest evidence, 38 randomized trials on 2095 people, fed whole pulses of every kind at a median 130 g a day for six weeks, and LDL cholesterol fell by 5.4 mg/dL (0.14 mmol/L). A second pooled analysis of 24 trials on 1938 adults, at about 3 oz (86 g) of legumes a day, found total cholesterol down 8.9 mg/dL (0.23 mmol/L), LDL down 0.16 and fasting glucose down 0.18, with moderate certainty. Whether a single lima bean trial sits inside those pools, the reviews do not say. The bean shows up by name in two glycemic index studies. One put the legumes it tested between 6 and 13, the other, in eight volunteers, put a set of traditional Pima foods including lima beans between 16 and 40. Both are low, and the two do not agree on the scale. Neither of them reports a figure for the lima bean itself. The only other measurement made on lima beans themselves was in a test tube, where they released the most iron of ten Philippine legumes, 9.5 percent. So read every number below as a number about beans in general unless we say otherwise. What a cooked large lima bean does carry, from our own table, is 508 mg of potassium and 7 g of fiber per 3.5 oz (100 g). American women aged 19 to 50 average 2364 mg of potassium and 15.4 g of fiber a day, about half and 60 percent of what is recommended. The authors of that survey named lima beans as one of the foods that could close the gap. Raw lima bean seed can also carry cyanide-forming compounds. EFSA's table lists 144 to 530 mg of total cyanide per kg of seed in older studies, against 20 mg for garden beans and peas, and one of three raw retail samples in Australia and New Zealand held 32 mg per kg. In the study EFSA summarizes, 9 hours of soaking removed only 30%, while 20 minutes of pressure cooking at 250 °F (121°C) or toasting at 399 °F (204°C) left none detectable. Ordinary boiling in an open pan was not tested.

The bottom line

If you eat lima beans for cholesterol, the dose that moved the trials was 3 to 4.6 oz (86 to 130 g) of cooked pulses a day, most days, for at least six weeks. In the bean subgroup the effect grew with the dose up to a cup a day, 0.25 mmol/L of LDL for every extra half cup. Nobody has checked whether lima beans in particular do that. On blood sugar there are two different questions, and they get two different answers. After a single meal, pulses gave a lower glucose rise than bread or rice in 28 of 40 studies and lower insulin in 16 of 24, and hunger fell in 3 of the 5 that measured it. Over the long run, the EU register refused the claim that low-GI foods such as legumes keep blood sugar, triglycerides and body weight normal. The meal studies measure hours. The claim was about years, and the register did not take the one as proof of the other. Iron is where the bean disappoints on paper, and once more the bean measured was a common bean rather than a lima. Young women absorbed 2.5 percent of the iron in whole bean porridge, and women in Rwanda with low iron stores absorbed 9.2 percent. Stripping out both phytate and polyphenols raised absorption 2.6-fold, and removing more than 95 percent of the phytate put 51 percent more iron into the blood. That was done with enzymes in a laboratory. For an ordinary pot, USDA retention factors for legumes as a group, not lima beans, say that boiling for 45 to 75 minutes and draining keeps about 70% of the potassium, 45% of the folate and 80% of the iron. Keeping the cooking water keeps a little more. Nobody measured what a pot does to the phytate in a lima bean. Our own table shows the cooked large bean at 508 mg of potassium per 3.5 oz (100 g) against 1724 mg dry, roughly a third. The table cannot tell you how much of that is water taken on and how much went down the drain with the cooking water. The WHO figure of about 1300 mg per 3.5 oz (100 g) for the beans and peas group sits between the two. In pregnancy, a Tehran cohort of 1026 women found that eating legumes at least 3.3 times a week before conceiving went with an odds ratio of 0.38 for gestational diabetes, while green lima beans were filed under starchy vegetables and showed no association at all. That is one observational study, and it cannot say the beans caused anything. The phthalate entry under safety is an odd one, and we report it as it stands. In 2369 American children and teenagers, a pattern of restaurant-prepared starchy vegetables such as plantains and lima beans, quick breads and citrus juice went with 37.2 percent higher urinary phthalate metabolite per standard deviation. The pattern is restaurant food, and the study cannot separate the bean from the kitchen it came out of. Who should be careful with lima beans. For cyanide, the benchmark is EFSA's acute reference dose of 20 micrograms per kilogram of body weight. EFSA keeps it for any food, and says it is likely over-conservative for foods other than raw apricot kernels, bitter almonds and cassava, because less cyanide is absorbed from them. In some child surveys that dose was exceeded up to 2.5-fold at the 95th percentile of intake, counting every such food together. By our own arithmetic, not EFSA's, a 154 lb (70 kg) adult reaches it at about 1.4 mg of cyanide, which raw seed at the older table values would supply in roughly 3 to 10 g. Those are raw figures. Cooked beans were not measured, which is why the cooking step matters and why we cannot say how much an open-pan boil removes. For potassium, NIH sets no upper limit in people with healthy kidneys. In chronic kidney disease, or with ACE inhibitors or potassium-sparing diuretics, it warns that even dietary intakes below the adequate intake can cause high blood potassium, and says people at risk should agree their intake with a doctor or dietitian. NIH also lists angiotensin receptor blockers such as losartan among drugs that can cause high blood potassium. The cooked large bean carries 508 mg of potassium per 3.5 oz (100 g). On allergy, a 2024 review reports positive skin tests to lima beans in 3.4% of asthma and rhinitis patients in a Delhi survey, mostly through cross-reactivity with other legumes, and one case of occupational asthma in a worker boiling and drying lima beans. No lima bean allergen has been identified, and a positive skin test is not proven food allergy. We found no study of lima beans taken with any medicine, and we hold no upper daily amount for cooked lima beans.
