I am not a fan of artificial sweeteners, but is there any reliable evidence that any of them are harmful or carcinogenic and in what quantities? I am old enough to remember when they took Cyclamates off the market and then said that it was not necessary to do so afterwards. (Also, there is the question of whether these artificial sweeteners result in people overconsuming calories counterintuitively.)

It's repeatedly stated that seed oils are bad, but I would like to see this explored more fully. I think there's a big difference between the highly processed, industrial seed oils found in supermarkets in plastic bottles, and organic, unrefined, cold-pressed oils, such as rice bran, sesame, flax, sunflower or nut oils. Also, any oil heated to a high temperature develops potentially unhealthy properties.

Polyunsaturated fatty acids are biologically active molecules no matter what their context. It is safer to consume monounsaturated fatty acid-rich oils than linoleic acid-rich oils. Excerpt: "Fatty acid composition in the Western diet has shifted from saturated to polyunsaturated fatty acids (PUFAs), and specifically to linoleic acid (LA, 18:2), which has gradually increased in the diet over the past 50 y to become the most abundant dietary fatty acid in human adipose tissue."

Thanks for that information. How about expeller pressed sunflower oill? According to the label on my bottle of Spectrum brand sunflower oil, it has11 g monosaturated fat and 1.5 g polyunsaturated fat.

That would be a high oleic acid sunflower oil. (web search - high oleic sunflower oil)

This should be a really good program... Relevant to all of us, and a nice break from politics and election stuff... (Although I do wonder what your guest thinks about MAHA, and RFK Jr. having a major role in the health issues in our country.) I think it's about time we actually DO SOMETHING about getting more discussion going, and more correct advice given on these topics rather than continuing to listen to the same status quo that is making us obese, weak, infertile and chronically and terminally sick with diseases that are mostly preventable. Not to mention the skyrocketing rates of autism affecting our kids... I appreciate that the surgeon general in my state was actually bold enough to advise against getting more Covid shots, especially for those who have little to no risk from getting Covid. What is it going to take to get REAL GOOD GUIDANCE from the public health and medical establishment?

My diet is very simple: no docs, no prescription or street drugs, but ORGANIC fruits, and, if available, meat, red included.

My question is - why only ground beef is available as organic but not steaks and the like?,

We're fortunate to have lots of organic, grass-fed choices for steaks etc. here in Sonoma County, CA

What do you think of the pre-diabetes definition and can pre-diabetes be mitigated or reversed?

I am a big fan of Nina's work. I am so glad that you are interviewing her. I use work from Nina, Zoe Harcombe, and others in some of the nursing courses that I teach. Please let her know that I try and disseminate real nutrition science the best that I can.

The reason those on the Mediterranean diet seem to do well (those in the Mediterranean) is because the slather everything with high quality Olive oil which is rich in biophenols. THe Med diet itself is not all that healthy but for the massive amounts of olive oil.

Actually, the Mediterranean diet lowers arachidonic acid intake. Comment by Steve Blechman: " The Mediterranean diet is low in arachidonic acid and rich in healthy fats such as monounsaturated fats found in extra-virgin olive oil (EVOO), nuts and omega-3 fatty acids from fish, which has been shown to lower the risk of inflammation, heart disease, cancer, diabetes and obesity, and other degenerative diseases." (web search - Steve Blechman New Red Meat Study Controversy)

Blechman appears to be unaware of the mechanism of action whereby increased oleic acid intake and decreased arachidonic acid intake attenuate inflammation. Norwegian animal science researchers explaiin it: "Because arachidonic acid (AA) competes with EPA and DHA as well as with LA, ALA and oleic acid for incorporation in membrane lipids at the same positions, all these fatty acids are important for controlling the AA concentration in membrane lipids, which in turn determines how much AA can be liberated and become available for prostaglandin biosynthesis following phospholipase activation. Thus, the best strategy for dampening prostanoid overproduction in disease situations would be to reduce the intake of AA, or reduce the intake of AA at the same time as the total intake of competing fatty acids (including oleic acid) is enhanced, rather than enhancing intakes of EPA and DHA only.

In 2013 Australian researchers came close to saying the same thing. Unfortunately, they mistakenly said this in their paper. " As endocannabinoids are products of dietary fats, modification of dietary intake may modulate their levels, with eicosapentaenoic and docosahexaenoic acid based endocannabinoids being able to displace arachidonic acid from cell membranes, reducing AEA and 2-AG production." (web search - Fatty acid modulation of the endocannabinoid system)

In 2024, these same Australian researchers published a paper entitled 'Effect of a High Linoleic Acid Diet on Pregnant Women and Their Offspring'. They totally ignored the dietary arachidonic acid issue. Consequently, they were at a loss to explain their findings in terms of endocannabinoid system activity.

Personally, I think that calling the bullet points.False consensus views is as misleading as calling them consensus views. There are some people who disagree with all of those points and some people who agree with them. A lot of the agreements and disagreements , however , are based on entrenched positions or vested interests. Rather than coming out with what ISIS a contentious list of alleged consensus views when it isn't a consensus at all is polemical journalism - it could have phrased much better and more accurately while still conveying the idea there were conflicts in opinion and factual basis. If Rav and Jay want to take them seriously they need to be a little bit more careful in their language.

Is this about Rav/Jay linguistic diet, with too mild or too spicy words?

I have several questions:

1) If low carb, high fat, keto etc are good for you why is all cause mortality higher in these groups is large studies?

2) If starches are bad for humans why is amylase the only digestive enzyme found in saliva where digestion begins?

3) Do you differentiate between plant based and animal based fats? Some studies indicate that avocado and coconut oil are superior to animal saturated fats

4) What is the evidence that our brain which loves and prefers glucose for energy is better off with ketones in the long term? Aren’t ketones for emergencies and survival, not a permanent lifestyle?

5) Several studies have shown that diabetes does not start from high sugar consumption but high fat consumption which is deposited in muscle tissue and it is this intramyocellular fat that blocks insulin absorption from the blood stream and thus leads to insulin resistance and then diabetes?

Please give us more notice on the questions, guys. I def have Qs but am seeing this too late. Thanks!
