I'm increasingly frustrated at the rapeseed oil (euphemistically called "Canola" oil by Canadian producers) and palm kernel oil that seems to be in almost all food. Pretty much everything at Trader Joe's seems to have one or the other. I was even at a Russian shop in Palo Alto today (Samovar, fun place) and found the poppyseed cake my grandmother used to make - except it was with margarine instead of butter, ugh.

Which of them are worth avoiding entirely?

Here are the fats and oils I think are bad:

- margarine (which is just canola and other crap oils hardened to make them stick in your arteries better)
- canola oil
- cottonseed oil (especially bad)
- palm kernel oil

I'm undecided about these:

- soybean oil
- sunflower seed oil
- avocado oil
- coconut oil
- peanut oil

I'm sure these are pretty good for you:

- olive oil
- butter
- lard (yes, I think lard is OK to eat)

Stringing nettles are medicinal. The thorns on other bushes might hurt you, but they help provide a safe place for other animals to hide and survive. I said food AND shelter for animals and people. Not all plants are food for humans, but all plants are food for something. And some provide shelter and energy sources.

Interesting tidbits:

Stinging nettles, like dandelions, were brought to America from Europe as food by some idiot and are now everywhere.
Nettles have stings exactly because they are very nutritious and would get eaten by deer otherwise.
As a general rule, plants may have either thorns or poisons, but not both, because they don't need both.

Before the fall on Adam and Eve, there were no thorns or poisons.

I see the Genesis stories as metaphor, not literally true. So I can accept evolution and still see a lot of meaning in the stories.

Many fruit seeds as well as vegetables and legumes contain ingredients that can be considered defense mechanisms and unhealthy in larger quantities. That's why I'm a big fan of fruits, they contain all the good stuff in maximum bioavailability while pretty much zero toxic ingredients. Fruits have been modestly vilified by the low carb / keto movement and some say they were only available in season and thus consumed in moderation, but I say you almost cannot eat too much whole fruit. Probably the most important part of a healthy diet imo, and delicious.

You are entitled to your own beliefs. But it is guaranteed that one day you will change your mind. Genesis answers most of the questions a person should ask themselves.

NEW STUDY - Seed Oil Fats Fuel Aggressive Breast Cancer Growth

Omega-6 fatty acids increase triple-negative breast cancer growth through mTORC1 pathway; population data links high omega-6/omega-3 ratio to increased all-cause and cancer mortality.


Rapeseed, aka "Canola" oil is very high in ω-6 linoleic acid:


Among polyunsaturated fatty acids, Canola oil contains a high level (21%) of linoleic acid (ω-6)

It functions well as a laxative, and it has antioxidant chemicals - just joking. Then again, what are seed and mineral oils?

This is a red herring. Linoleic Acid is essential for the body as it can't produce it. It's always a question of how much, sola dosis facet venenum. Plenty of healthy foods (e.g. nuts, esp. Walnuts among the healthiest of them all) are high in LA. Even its inflammatory potential is highly debated. LA is not a big problem when consumed in moderation, it's actually essential. It's the same as with the veggie and vegan cooks which claim milk fuels cancer, which is possible, e.g. due to IGF1, but it also strengthens bones and the immune system (which in turn prevents cancer). Testosterone similarly fuels prostate cancer, so for certain patients it may make sense avoiding T or LA, but without preexisting condition you are usually worse off without essential hormones and nutrients (such as fatty acids) since it prevents a whole lot of other things. Don't fall for this one sided junk science

You may want to check that. Soybean plants do not have ovaries and cannot make animal estrogen. Plants can produce phytostrogen that can make the body think it has too much estrogen and thus have the opposite effect of estrogen from a BC pill. Even that effect is minor, though.

A team of researchers in Japan has succeeded in making catfish all female with a compound found in soybeans -- a development that promises to increase the production efficiency of this and other species whose females are more valuable than males in the food market.

The team, from Kindai University's Aquaculture Research Institute and based at the institute's Shingu Station in Shingu, Wakayama Prefecture, used isoflavone -- a compound found in soybeans similar in effect to female hormones -- to create the all-female groups of catfish. The feat is a Japan first, according to the university.

As female catfish grow faster than males, "by making them all female, production efficiency will rise," commented team leader and aquaculture science associate professor Toshinao Ineno. "This can be applied to other farm-raised fish whose females are more valuable." ...

While 68% of catfish in the ordinary water tank were female, 96% of the catfish kept in the water with genistein at a concentration of 100 micrograms per liter were female. A concentration of 400 micrograms per liter yielded a 100% female group, the same as in the female hormone-treated water group.


OK, so not exactly estrogen, but hat estrogen-like effects.

That happens naturally with ocean fish around here. Part of nature that fish turn from male to female as they age.

Happens in my reef tank. You can buy a pair of decent clownfish 'mated' for ~$150. Or you can take the risk and buy two unknowns for around $50 each and wind up with two females that fight each other. Usually the larger fish becomes female if you start out with two males. Mine are black and white (I risked it) and the female has a trace of orange like Nemo on it's lips. Like lipstick haha..
