The Stew A Man Once Traded His Inheritance For

Lentils are among the oldest crops we grow. Here's the soup, and the trial that found a real, modest effect on cholesterol.

There's a story in Genesis about two brothers. Esau comes in from the fields, worn out and starving.

His brother Jacob has a pot of red stew going. Esau wants some. Jacob names his price, and the price is Esau's birthright.

He takes the deal. The text names what was in the pot. Bread and lentil stew.

Here's a better version of that stew…

Ingredients , Serves 4

45 minutes start to finish

1 1/2 cups brown or green lentils, rinsed
2 tablespoons olive oil
1 onion, diced
2 carrots, diced
2 celery stalks, diced
4 cloves garlic, chopped
1 teaspoon ground cumin
1 bay leaf
1 can chopped tomatoes, 400 grams
6 cups water or stock
Salt and pepper
1 lemon, cut into wedges
Handful of parsley, chopped

Method

Warm the oil in a big pot. Cook the onion, carrot, and celery over medium heat for 8 minutes, until soft.
Add the garlic and cumin. Stir for one minute, until it smells good.
Add the lentils, bay leaf, and water or stock. Bring it up to a boil, then turn it down to a simmer.
Simmer uncovered for 25 minutes, until the lentils are tender.
Stir in the tomatoes now, at the end. Cook 5 more minutes and season well.
Ladle it out. Squeeze lemon over each bowl and scatter the parsley on top.

Why The Tomatoes Go In Last

That step trips people up, so let me explain it.

Acid slows down the softening of lentils and beans. Add tomatoes at the start and you can simmer for an hour with the lentils still chalky.

The cooks at America's Test Kitchen have tested this in their own kitchen. It's applied cooking science rather than a journal paper, but the effect is easy to reproduce at home.

Salt is a different story. The old warning that salt toughens pulses turns out to be wrong, and salted water actually softens the skins.

One Of The Oldest Things We Eat

Lentils belong to a small group called the founder crops. These are the eight plants that started farming in the Fertile Crescent.

Wheat, barley, peas, chickpeas, flax, and a couple of others. Lentils are on that list.

Archaeologists have pulled charred lentils from sites in Syria and the Jordan Valley dating back around 11,000 years. At many early farming sites in the region, lentils are the most common legume found.

People have been making versions of this soup for a very long time.

What One Bowl Gives You

A cooked cup of lentils, about 198 grams, carries 230 calories.

For that you get 17.9 grams of protein and 15.6 grams of fiber, per USDA data. The fiber number is the one to notice, since most adults get nowhere near enough.

There's also 6.6 milligrams of iron, 358 micrograms of folate, and 731 milligrams of potassium.

All of that for about 30 cents a serving.

What The Trials Show

Pulses have been studied properly, which is more than I can say for a lot of foods I write about.

A team at St. Michael's Hospital in Toronto, led by Vanessa Ha and John Sievenpiper, pooled 26 randomized trials covering 1,037 people.

Eating about one serving of pulses a day lowered LDL cholesterol by a small but real amount. Their analysis ran in 2014 in the Canadian Medical Association Journal.

Call it a 5 percent drop. Not dramatic, and not nothing either.

THE FINDING: A 2014 analysis in the Canadian Medical Association Journal pooled 26 randomized trials of pulses, covering 1,037 people. About one serving a day, roughly 130 grams, lowered LDL cholesterol by around 5 percent. The work came from St. Michael's Hospital in Toronto.

Blood sugar is the other piece. Alison Duncan at the University of Guelph, working with Dan Ramdath, swapped half a portion of rice or potato for lentils.

The rise in blood sugar after that meal dropped by about 20 percent with rice, and about 35 percent with potato. Published in 2018 in the Journal of Nutrition.

Note what that study did. It replaced part of the starch, rather than adding lentils on top of it.

There's a longevity finding too, from an Australian team who followed 785 adults over 70 across five countries. Legume intake was the strongest food predictor of who was still alive seven years later.

That one was published in 2004, and it watched people rather than assigning diets. Treat it as a clue, not a promise.

About The Iron, Honestly

Lentils carry a good amount of iron. There's a catch, and you should know it.

Plant iron comes in a form your gut absorbs less easily than the iron in meat. Compounds in the lentils themselves, called phytates, hold some of it back.

You'll read that a squeeze of lemon fixes this. The truth is softer than that.

In single-meal studies, vitamin C clearly boosts plant iron absorption. When researchers looked at whole diets over time, the effect largely washed out.

So squeeze the lemon. It makes the soup taste alive, and it may help a little. Just don't count on it as an iron strategy.

Three Things Worth Knowing

Don't Soak Them

Lentils don't have the thick coat that dried beans do, so soaking buys you nothing. Rinse them, pick out any stones, and get cooking.

Pick The Right Colour For The Job

Red and split lentils collapse into a thick puree in about 20 minutes. Brown, green, and dark French ones hold their shape for around 30. This soup wants the ones that hold.

If They Give You Gas, Start Small

The culprit is a group of sugars your gut bacteria feed on. They dissolve in water, so draining canned lentils and rinsing them well cuts the load. Build up your portions slowly.

Here's What I'd Do This Week

Make one pot on Sunday. It gets better by Tuesday.
Swap lentils in for part of the rice or potato. That's how the blood sugar study did it.
Add the tomatoes at the end. Acid early keeps them hard.
Buy dried, not canned, for soup. Cheaper, and no soaking required.

Not many foods give you 15 grams of fiber, a real cholesterol effect, and change from a dollar.

Lentils have been feeding people since farming began. The pot Esau traded for was probably worse than yours.

Make a batch this week. Lemon over every bowl.
