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…

Yup. Rich/Upper Class people used to consume a lot of Ghee (rich people - they can afford it. Upper class - usually because they're connected to temple food preparation and ghee is abundant there). The rest of us used a tiny amount at the very end for flavor. Peanut oil & Coconut oil were common in our household. Followed by sunflower oil.

> Indians in India have skyrocketing diabetes and obesity numbers in recent decades About a decade ago, my Indian colleagues told me that Indians had been encouraged to switch away from ghee, based on health concerns. I forget which oil most moved to, but I think it was palm, vegetable or sunflower oil. In addition, they said consumption of refined sugar had skyrocketed , where palm sugar had previously been used. Gh…

> I wonder if it's these ghee alternatives and refined sugar are the main causes of increased diabetes and obesity.

This is the most likely cause. People in India are consuming way more sugar, refined flours and seed oils than they used to three decades back. That is when all these colas/biscuits/chocolates/chips/pizzas and oils started being advertised heavily on television.[1]

Eat fresh, local, natural. Butter, simple olive oil, animal fats. Food trends are trends because they are profitable. The people telling you its healthy are those selling it to you. The US must also move away from soy beans and corn syrup.

We should also remember that humans can be perfectly healthy without consuming animals and soy products in moderation aren’t harmful.

We can eat a whole foods, plant-based diets without negative health effects or the environmental damage caused by factory farming.

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 fa…

As I understand it, the evidence for erucic acid being harmful has been called into question more recently. See the footnotes for https://en.wikipedia.org/wiki/Erucic_acid#Health_effects

I'm glad that this study was published -- it seems interesting -- but I hate the controls chosen. Coconut is a weird oil. It contains a lot of lauric acid, a fatty acid found in high amounts in coconut, palm kernel oil, and pretty much nothing else. You should also compare soybean to a normal oil, like olive oil, palm oil, duck fat, butter, lard, canola, or something else.

Imagine you want to evaluate the effect of switching to [insert your favorite language here] on programmer productivity, so as a control language for comparison, you choose Haskell. Doesn't that sound just a little weird?

Canola is a genetic evolution of rapeseed. They are not the same thing.

Meh, it's all just Rapeseed. No one considers Granny Smith apples to be a different species from Red Delicious cultivars.

I used to eat sardines every day trying to get the health benefits of fatty fish. They were packed in soybean oil. I drank the oil too. With time I began to have bizarre mental issues that I finally tracked down to the sardines. Sardines packed in olive oil don’t cause this issue. That’s my anecdata to share.

Whoa, how did you track?

Humanity has been using Olive Oil for at least 1000 years. So that seems pretty safe to me.

Yes, but olive oil has a low smoke point and is not used for the same applications. Otherwise I'd happily use it for everything.

This is something of a modern myth — me and my ancestors have been using olive oil for all forms of cooking for centuries. It does fine in high heat applications, you just need to vent off the smoke. Flavor isn’t affected in any noticeable way. There’s some YouTube videos with more science behind the “low smoke” oils and the myths of their being bad for cooking at high heats.

Fixating on lineolic acid is kind of hard when basically all high-heat vegetable oils contain a lot of it. If lineolic acid is the problem then basically every unsaturated cooking oil other than olive oil is now unusable. Maybe canola, depending on how much lineolic acid is safe.

Avocado sits somewhere between olive and canola in terms of linoleic acid content (one reference said 13%; another said 7–20%), and has one of the highest smoke points of all cooking oils at 271°C. It's also pretty flavour neutral. It's a fantastic choice for high-heat cooking.

Yeah, I tend to use avocado oil when it's available or refined high-heat olive oil when it's not. The heavy processing of high heat olive oil is concerning but it does mean low linoleic acid.
