tell me you've never worked in sales without telling me you've never worked in sales

Can we apply this argument to everything that's for sale? Seed oils are for sale too...

Yes, you absolutely should look to sources other than walnut oil salesmen for information regarding the benefits and drawbacks of walnut oil.

My understanding is that most of the oils we use are unhealthy. They are highly processed and inflammatory. The good oils are avocado oil, extra virgin olive oil and coconut oil. Is this correct?

There are 3 characteristics of the oils that influence how healthy they are.

The first is the fatty acid profile, i.e. the relative quantities of fatty acids.

It is best when the most abundant fatty acid is oleic acid. This is true for olive oil and avocado oil and for certain varieties of other oils which are claimed to be "high oleic", e.g. high oleic sunflower oil.

For the oils with high percentage of saturated fatty acids, it is better to have little palmitic acid and more of either longer fatty acids, i.e. stearic acid like in cocoa butter or shorter fatty acids, like lauric acid in coconut oil.

Besides the fatty acid profile, some oils are known to contain other substances with favorable influences. This is known with reasonable certainty only for extra virgin olive oil, which is good for preventing cardiovascular diseases but it is not known which exactly is the substance with the good effect.

And third, there are oils which may contain other substances with bad effects, as shown here for the soybean oil or as is the case for the traditional rapeseed oil with erucic acid. Such oils must be avoided, at least until the undesirable substance is identified precisely and its removal from the oil becomes possible.

> Indian ghee We have been using ghee in India for thousands of years. If immigrant Indians are having problems, they should look into what changed in their diet and lifestyle after they immigrated.

Indians in India have skyrocketing diabetes and obesity numbers in recent decades. 20+ years ago you would struggle to see a single non thin person. Drastic increase in quantity of ghee (and sugar since a lot of Indian tests are a lot of ghee and sugar) consumed and reduction in labor (trading strenuous, perspiring work for air conditioned, sitting work) could be relevant factors that make ghee consumption from the p…

I have noticed that. I have also noticed that youngsters started adopting Western habits and diets and consumption patterns over the same time period.

> Drastic increase in quantity of ghee

Unless you are rich or belong to the upper middle class, ghee is generally consumed in moderate quantities because the family would not be able to afford it.

Today, ghee is between Rs. 500-600/kg. Seed oils are about Rs. 125/kg.

Seems from the article that soybean oil contributes to making people obese and unhappy.

Maybe. The study only looked at mice though.

There are others. The skyrocketing rate of use of vegetable oils correlates quite highly with rate of obesity.

1. We have common genes going back to mammals who did experience torpor. 2. A study doesn't "own" their data and have exclusive right to interpret this data 3. Someone selling something that they think is beneficial to their customer, does not mean it is not beneficial. I would say most people who sell things honestly think their customers will benefit from their product.

What is soybean oil traditionally called in the US? I've never actually seen "soybean oil" myself (though it surely exists). Is this the same as "vegetable oil"?

I expect that most of the soybean oil consumed in the US is consumed as an ingredient in something else—salad dressing, sauces, snacks, etc.—rather than a bottle of "soybean oil" (usually "Vegetable Oil") in their pantry.

I kinda doubt there's a ton of overlap between "right wing" twitter and HN, but there's been a decent amount of hate on seed oils (especially soybean oil) over there lately. Here's one of the bigger accounts promoting it in case anyone here'd wanna glance at what those people might be saying: https://twitter.com/SeedOilDsrspctr

You mentioned right wing. I suspect it would be owing to the politicization of meat consumption and advocacy for the carnivore diet.

> In all likelihood, it is not healthy for humans. I'm sure their mouse studies are showing them something, but this is the kind of bold claim that wants to be tested anthropologically as much as bio-pharmacologically. China is the leading consumer of soybean oil. It's been a dietary staple since the 11th century. Any claim it's generally unhealthy has to reconcile with the fact that it's been used for 1000+ years. P…

In aggregate it has, but the processing and quality of the oil has certainly changed. Notwithstanding, there has been a steep increase in total consumption of vegetable oil since the mid 20th century, owing to boxed / processed products. It's possible that the primary issue is oil consumption is not as moderate as it was.

In mice . Let's temper the usual nutritional conspiracy allegations and grand proclamations of effects on humans until someone trained and knowledgable provides an interpretation of this study. Most of these rodent studies end up not being applicable to humans anyway.

There is plenty of research done on the harmful effects of seed oils. It’s not a stretch to assume this is yet another study demonstrating this in mice models.

But there also seems to be a ton of research suggesting the seed, nut and legume consumption is very healthy...
