Vinegar with bread……..even if for sure the bread Ruth ate was not processed white bread……see the commentary of Dr Greger below Ruth chapter 2: 14 And Boaz said unto her at meal-time: ‘Come hither, and eat of the bread, and dip thy morsel in the vinegar.’

Ruth chapter 2: 14 And Boaz said unto her at meal-time: ‘Come hither, and eat of the bread, and dip thy morsel in the vinegar.’

יד וַיֹּאמֶר לָה בֹעַז לְעֵת הָאֹכֶל, גֹּשִׁי הֲלֹם וְאָכַלְתְּ מִן-הַלֶּחֶם, וְטָבַלְתְּ פִּתֵּךְ, בַּחֹמֶץ;

Consuming vinegar with a meal reduces the spike in blood sugar, insulin, and triglycerides. And it appears to work particularly well in those who are insulin resistant, on their way to type 2 diabetes; no wonder the consumption of vinegar with meals was used as a folk medicine for the treatment of diabetes before diabetes drugs were invented.

Many cultures have taken advantage of this fact, mixing vinegar with high glycemic foods like white rice—in Japan, for example, to make sushi; dipping bread into balsamic in the Mediterranean; a variety of sourdough breads throughout Europe, which cause lower blood sugar and insulin spikes. And you can do the same with boiled white potatoes by adding vinegar, and cooling them to make potato salad.

Adding vinegar to white bread doesn’t just lower blood sugar and insulin responses, but increases satiety—the feeling of being full after a meal. If you eat three slices of white bread, it may fill you up a little, but in less than two hours, not only are you as hungry as you started, but actually hungrier—less satiated than when you began. But if you eat that same amount of bread with some vinegar, you feel twice as full. And even two hours later, you’re still feeling nearly just as full as if you just ate the three pieces of bread plain. But this remarkable increase and prolongation of satiety took nearly two tablespoons of vinegar. That’s a lot of vinegar.

It turns out even just small amounts of vinegar—two teaspoons with a meal—can significantly cut down on the blood sugar spike of a refined carb meal—a bagel and juice in this case. So, you could have a little side salad or even just add it to some tea with lemon—it’s only two teaspoons. Or scrap the bagel with juice, and just have some oatmeal with berries instead.
