ETH Zürich turns lentils into fibrous meat texture with a household freezer

Food engineers at ETH Zürich, led by professor Patrick Rühs, published a method in npj Science of Food that turns pureed lentils, peas, and beans into a fibrous, meat-like texture using nothing but heat and a household freezer [72]. The technique, directional freezing, forms parallel ice crystals that leave long fibers behind once the gel thaws, mimicking the muscle-fiber structure that gives meat and fish their chew [72]. PhD researcher Andrea Bach says the method works with legume species covering most of the world's legume production, and red lentils, black lentils, and mung beans produced the strongest fibers [72].
“During chewing, a directional, fibrous structure provides a distinctive bite that is familiar to – and enjoyed by – many people from meat or fish.”

“This method is so simple that it can be performed easily by anyone in a household kitchen.”

By the numbers
96%of global legume production is covered by species the freezing method works with, per the researchers [72]

Vegan diet without exercise cuts muscle mass in over-65s in new trial

A 12-week randomized trial out of Wageningen and Maastricht universities put 72 healthy adults over 65 on a self-selected vegan diet, their usual omnivorous diet, or a vegan diet paired with resistance exercise, then scanned their thighs and tracked muscle protein synthesis [6][12]. The vegan-only group cut its protein intake and lost real muscle, while the group that added resistance training held onto most of it [6]. The result doesn't indict plant protein itself: earlier trials in younger adults found mycoprotein- and legume-based vegan diets matched omnivorous diets for building muscle [7][8].
By the numbers
-27.7 g/daverage protein-intake drop within the first week on the self-selected vegan diet, compared with no significant change on the omnivorous diet [6]
-1.15 kgappendicular lean mass lost over 12 weeks on the vegan diet alone, versus a small gain on the omnivorous diet [6]
-0.35 Lthigh muscle volume lost when resistance exercise was added to the vegan diet, versus -0.61 L lost on the vegan diet without exercise [6]

UNC study finds oxalate in healthy plant foods may worsen IBD inflammation

Researchers at the University of North Carolina found that people with Crohn's disease or ulcerative colitis carry consistently lower levels of two gut proteins that clear dietary oxalate, a compound found in every plant food including spinach, almonds, and sweet potatoes, whether or not their gut is actively inflamed [1][3]. Crohn's patients had significantly more oxalate in their stool than healthy people eating similar amounts of plant food, pointing to a biological difference in how their gut handles it rather than what they eat [1][3]. Lead researcher Anna Salvador says the findings don't call for cutting plant foods, only for oxalate-aware diets in genetically susceptible IBD patients [1].
“For the first time, we observed that IBD patients and healthy controls were eating similar amounts of plant-based foods yet CD patients still had more oxalate in their stool.”
Anna Salvador, PhD, RD, postdoctoral researcher, UNC School of Medicine · [1]
By the numbers
60%lower survival rate in mice fed an oxalate-supplemented diet alongside a colitis-inducing agent, compared with mice given no added oxalate [1]
75%of patients with low expression of the SLC26A6 oxalate transporter had the more severe, stricturing form of Crohn's disease [1]

Research & Nutrition
A meta-analysis of seven prospective studies found vegans carry 23% lower total cancer risk than non-vegetarians, with breast cancer risk down 20% [24].
Plant-based diets tied to 26% lower risk of cognitive impairment and dementia in a pooled analysis of more than 221,000 adults [29].
Healthful plant-based diets linked to 17-23% lower liver cancer risk in a meta-analysis, but the least healthful plant-based diets raised breast cancer risk 3% [22].
A whole-food, plant-based diet cut LDL cholesterol 17.9% compared with a standard American diet in adults with a genetic high-cholesterol disorder [19].
A vegan Mediterranean diet beat a traditional Mediterranean diet on LDL, triglycerides, and pain scores in a small fibromyalgia trial [16].
A vegan multinutrient supplement significantly raised omega-3 index and vitamin D levels in young vegans, with no added benefit from doubling the dose [10].
Plant-based dietary patterns lowered C-reactive protein, an inflammation marker, by roughly 1 mg/L across seven clinical trials, though the evidence was rated low-certainty [25].
A processed plant-based meat diet cut TMAO, a cardiovascular risk marker, compared with a red meat diet in a randomized crossover trial [26].
Renaming a menu's plant-based option so it doesn't mirror the meat dish by name pushed plant-based selection up to 44.6%, from 37.4% when the names matched [27].

Scientists in Sri Lanka confirmed Mus dumbara, a new spiny mouse species found only in the Knuckles mountain range, after more than two decades of genetic analysis [68].
One Good Thing
The nicest vegan news today has nothing to do with a lab. It Doesn't Taste Like Chicken published a fresh batch of 50-plus bean recipes this week, the kind of unglamorous, thirteen-years-in-the-making know-how that keeps a movement fed: pizza beans, chickpea salad sandwiches, and the reminder that a can of chickpeas holds a free egg replacer in its liquid [58]. No funding round, no ruling, just someone who has done this a long time making it a little easier to eat well tonight.
