garlic hack: I cut off the top of the garlic head and bake in the microwave, approx 1 minute per garlic head (depending on how powerful your microwave oven is, mine is not v. powerful). The garlic becomes soft and sweet and it's much quicker than roasting in the oven. Once it's cooled down, it's really easy to remove the outer skin and add to salads, soups, anything really. A great timesaver

No one seems to want to answer me on these topics, how can so many doctors be so different when it comes to food. Dr Ken Berry, Sten Eckberg along with many others swear by Keto and the Conivoire diet while Dr Neal Barnard and others swear by the Vegan diet. One and many doctors say that it's not the saturated fat that's the problem and that it's good for us while the others say that it is bad for us. They do agree that sugar and processed foods are bad. They all have scientific proof and stats to back up what they say. What is going on? This really confuses people, who should we believe? I would like to see all these doctors have a debate together... I don't think either one is feasible, I still believe that it should be balanced between the 2 and eliminate all the junk food and eat whole foods...

Yes, thanks for posting! I couldn't have said it better myself! All these excellent doctors you've mentioned have some very opposing views. Yep: Who are we to believe? A debate would be great!

Such an interesting discussion!! I became hard-core vegan in June 2021 after the shocking heart-disease death of my beloved brother. I was wearing wigs at the time due to progressive hair loss which I thought was related to medication I am taking. Now, 18 months later, I notice that my hair is looking much better. The bald spots all over my head are gone, and the parts are more normal. Yay! I'm still wearing wigs, but at least I have the option now to go without. Wonderful information!

With respect to Alzheimer’s, they didn’t mention turmeric. Nutrition Facts Organization website lists some studies where daily consumption of turmeric actually reversed cognitive decline. Also, in India (in general in the Indian subcontinent), Alzheimer’s is nearly absent.

@RK-tf8pq Жыл бұрын
@@a_teez8913 it is turmeric dose dependent, so it is usually not recommended to take iron supplements with turmeric supplements. I don’t know how much iron absorption is reduced when turmeric is taken at a doses found in whole spices. Also iron absorption can be significantly increased when taken with vitamin C. I need to further research this to find how much effect this has when turmeric is consumed as a spice. I remember one study showing 20% to 90% reduction in iron absorption depending on turmeric dose, don’t remember if it was turmeric supplement or the spice. I guess we can make sure to consume turmeric separately from foods high in iron. For iron supplements, most of them are recommended not to take after meal or with other supplements. On the other hand, in case of iron build up in the body, turmeric can be useful to reduce excess iron (turmeric supplements have shown to reduce iron build up by chelation, and it is considered best supplement to reduce iron build up. (Reduction in absorption of iron by turmeric is a different phenomenon than reduction in build up of iron by turmeric, in the former case, it just stops the absorption by binding with some peptides responsible for iron absorption, while in the latter case, it chelates already built up iron). By the way, excess iron is also not good, as it oxidizes which can cause diseases. Absorption of non-heme iron is regulated by the body, but heme iron absorption cannot be regulated and can cause buildup.

@RK-tf8pq Жыл бұрын
@@kevinwilson3337 I think that you should listen some of the episodes of to Dr. Will B, one of the guests today who is an expert in the area of microbiome. Bloating May be related to dysbiosis of gut microbe. Meaning your gut may not have microbes to effectively process plant foods (fiber). In that case, you need to introduces plant based foods very slowly (go very slow over weeks) and build up your gut microbes (increase the variety of microbes). Avoiding plant foods removes symptoms such as bloating but it only increases dysbiosis further according to Dr. B. (One needs to go towards what is known as symbiosis). Suddenly going to full plant based when your gut is not ready is like doing heavy exercise without prior training. One needs to slowly build up to such an exercise. That is according to Dr. B’s prior answers to those who have gut symptoms upon consuming plant based foods. You can check out his previous interviews, or ask your own question when he is live next time (he is a monthly regular on Exam Room Live).

Cholesterol is a waxy substance that is carried by LDL or HDL. The level of cholesterol in the body is tightly regulated by the body and is essential for life, without cholesterol you would be dead. My wish for the new year is for Dr Barnard and whoever state LDL and HDL is cholesterol correct themselves and state it for exactly what it is. A waxy substance that is made by the body. By no means is Doctor Attia tis not the only one that recognizes this fact, eating cholesterol rich food doesn’t raise the level of cholesterol in your body. Your body must convert what it wants to use through the liver; what is not used is excreted in your poop.
