I have had gallbladder trouble myself and have learned quite a bit about the gallbladder and liver. The gallbladder is merely an “overflow”/storage bladder for the bile that the liver produces, drip by drip. Every time you eat something “fatty” (aka oily, greasy, high-fat), the digestive system needs bile to process it, so if there isn’t enough sitting in the bile duct, the gallbladder will contract and spill some of the bile it has been storing into the bile duct which empties into the small intestine.

Bottom line: No gallbladder, less bile available, so *any* fat (animal or vegetable/seed) will be hard to digest and can cause your problems.

What I do is have the majority of fats in my diet when I haven’t had any for several hours (first meal of the day, any meal or snack where I haven’t consumed anything fatty/oily for 4-6 hrs). This gives the liver time to fill up the bile duct with bile. Since you don’t have a backup (the gallbladder), limit yourself to small amounts of fat each time you eat them–the bile duct doesn’t hole much bile.

I’ve tried “ox bile” supplements, and they did seem to help. A Chinese gallbladder specialist (MD) suggested I could try them. I found some in a health food/supplement shop.

It may not be the animal products, but the fat content. Experiment with a little whole milk kefir or yogurt, for instance. And omega-3 rich “fatty fish” like salmon and sardines.

However, be careful to refer to articles who have not separated between butter and margarine. These are not the same.

Hello Norma! I’m happy to answer some questions about peanut oil for you. Here’s a rundown of the benefits and risks:

Peanut oil is rich in monounsaturated and polyunsaturated fats, especially oleic acid and linoleic acid, which are often considered “heart‑healthy” fats. It also contains vitamin E, an antioxidant that helps protect cells from damage by free radicals, supports the immune system, and contributes to skin health. Because refined peanut oil has a high smoke point (around 400‑450°F / 200‑230°C), it is reasonably stable under heat, making it useful for frying and cooking at high temperature without breaking down as quickly. Some studies also suggest that replacing saturated fats with oils high in unsaturated fats (like peanut oil) may help reduce LDL (“bad”) cholesterol and lower risk of heart disease.

On the other hand, there are some risks or drawbacks to consider. Peanut oil is high in omega‑6 fatty acids, which in excess (especially relative to omega‑3s) may promote inflammation. Consuming a diet very high in omega‑6 and low in omega‑3 may contribute to chronic inflammatory conditions. Also, because it is calorie‑dense, overuse can contribute to excess calorie intake and weight gain. And though peanut oil has a high smoke point, if it is overheated or used repeatedly it can degrade, oxidize, and generate harmful compounds.

I hope this helps clarify the information for you! Thank you for the question. –Ina, Food Revolution Network Team

The seed oils most commonly used for these purposes are canola (also known as rapeseed), corn, cottonseed, grapeseed, soybean, sunflower, rice bran, and peanut oils. Dr. Cate Shanahan, a vocal critic of these oils, dramatically refers to them as the “hateful eight.”
Peanut oil is listed in the paragraph above but nowhere in the article. My son uses peanut oil to pop popcorn, and I was hoping to see what your research says about that. Read the entire article and no mention of peanut oil. Disappointed.

Thanks very much for sharing this with us, Kristen. I’m glad this article resonated with you.

For nutritional value, cold-pressed sunflower oil is better — it’s less processed and retains more beneficial compounds.
For high-heat cooking, refined (especially high-oleic sunflower oil) may be more stable and less likely to oxidize.

So, both can be beneficial when used for different purposes, minimally of course. –Ina, Food Revolution Network Team

I was getting stressed out since different plans I have been looking at regarding reversing Type 2 diabetes all seem to promote animal fats and proteins. I cannot eat meat from mammals or birds and can only eat chicken eggs. I get violently sick, I mean it is like a scene from The Exorcist and I scare people. I can’t eat for a while after because it hurts . Even bullion will make me ill. It has something to do with having my gallbladder out.
I grew up eating whole grains and no white sugar. I try to mostly eat home cooked meals and we mostly use olive and coconut oil.

We have some cold pressed sunflower oil. Is that any better than regular sunflowrr oil? My husband wants to find a cheaper oil.

Keep up the good work.

I am a massage therapist and Love using jojoba oil as it is beneficial to skin.
I use it on my face, and get many compliments for my skin, which at the age of 72 is no small thing

His research, not for profit foundation, and book are extremely damning of seed oils, along with their strong correlation (which I appreciate isn’t always causation) with so many of today’s illnesses which were virtually non-existent in the past. The research looks at extremely different cultures and extremely limited diets, which were super different to each other, but all without any seed oils and all without almost all of modern day illnesses.

Thanks for the question, Peter! We published an article on the topic of Coconut Oil a while back–here it is. I hope this resource can answer your questions and provide you with some more insight! https://foodrevolution.org/blog/coconut-health-benefits/ –Ina, Food Revolution Network Team
