Liver: Love It or Leave It?

I recently sat across a restaurant table from an individual who ordered liver and onions. As a kid I was required to eat liver because it was good for me, but I recently heard a famous TV doctor advise liver avoidance. So what’s the answer? Should humans consume pâté, foie gras, liverwurst, chopped liver, or liver and onions.

Consider beef liver. A 3 1/2 oz. serving has about 150 calories and more than 20 grams of protein. Being a good source of lean protein makes liver an attractive option to anyone watching his or her weight. Liver might also prevent anemia because a serving can have more than a quarter of the daily amount of iron humans require, and a whopping 988 percent of our daily value of Vitamin B-12. Iron-deficiency anemia is a risk for women of childbearing age, children and adolescents, according to the 2010 Dietary Guidelines from the U.S. Department of Health and Human Services. Vitamin B-12 deficiency anemia is also a risk for some people. Both interfere with the production of red blood cells and can cause weakness and fatigue.

Lean protein, iron, and Vitamin B-12 are benefits of liver, but it has a downside too. Too much iron, for example, can be harmful. Plus, liver may increase levels of bad LDL cholesterol in the blood.

Liver is also rich in Vitamin A, and while some Vitamin A is good, too much liver, or liver consumed by someone already taking Vitamin A supplements, might lead to Vitamin A toxicity. Effects of Vitamin A toxicity can include osteoporosis and drug interactions. (The form of Vitamin A in fruits and vegetables does not cause toxic symptoms, however.)

(Continued Below)

So, while acknowledging that liver can be a good source of nutrients, TV’s Dr. Mehmet Oz has said he doesn’t recommend its consumption because it contains too many toxins. That’s because an animal’s liver serves as a filter, and when it encounters chemicals it can’t process, it stores them. PCBs and other toxins animals are exposed to are stored in their livers. Finally, organic compounds called purines are found in liver and can cause gout or kidney stones in people prone to those conditions.

What is the answer? For liver lovers, it’s all about moderation. Those who take supplemental Vitamin A should be wary of eating more than one serving of liver per week. And anyone who craves liver might be wise to buy organic if possible to reduce the hormones and toxins consumed along with its nutrition.

Of course, if you hate liver, you can use toxins and pruines as justification for never touching the stuff again. Instead, get your protein, iron, and Vitamin A from foods you actually enjoy eating.

I will only eat liver from an organic grass raised beef or wild elk and then soak it in milk before frying. Yummy! Liver in stores is pale brownish from the junk they feed to cattle in feeder lots filters. This is deep red and tastes like I remember as a little girl. Also only cook until barely pink in the middle, it will be perfect when you get it to the table, not grainy like some people cook it .

I love liver and onions and gravy. My mother made the best ever. Mother was raised during the depression where you ate the pig from nose to tail, and whatever beef you could get. My daughter will make it for me occasionally, but won’t eat any. I also love gizzards, chicken hearts, etc. Calves liver is the best. I’ve never heard of soaking in soda water, but I’ll try it. My daddy loved kidneys, but I couldn’t stand the smell of it cooking.

Love liver with lots of onions and gravy!!!! As for the toxins there is not much and if you’re afraid of toxins soak the liver in soda water either over night if fresh or for a couple of hours if out of market….People have been living well on internal organs such as liver, hearts, kidneys, gizzards, etc. Everything in moderation is the key here…Dr. Oz needs to go back to the yellow brick road……he has too many misconception’s…..

Haha! I would be one of those people you see ordering liver in a restaurant. Good quality liver prepared in one of the many delicious ways is a great way to add a nutrient dense food to your diet. Eating it a couple times a month should be enough and if you possibly can, try to source from an animal that was humanely raised–grass fed ideally. One thing, though, the liver doesn’t store toxins any more than any other cut of meat or fat; that’s a common misperception Never eat the liver of certain animals like bear which has toxic levels of vitamin A. Other good organ meats are heart and kidney; love steak & kidney pie 🙂

If you notice a hole in the upper left-hand corner of your Farmers' Almanac, don't return it to the store! That hole isn't a defect; it's a part of history. Starting with the first edition of the Farmers' Almanac in 1818, readers used to nail holes into the corners to hang it up in their homes, barns, and outhouses (to provide both reading material and toilet paper). In 1919, the Almanac's publishers began pre-drilling holes in the corners to make it even easier for readers to keep all of that invaluable information (and paper) handy.
