Hi Timar,
Many thanks for your reply.
I asked this question cause the LDL-C went up in the period when I switched from a bread-based breakfast to one with vegetables, 2 eggs and tuna/salmon (more paleo compatible sort of). It might have been a coincidence and the higher LDL-C is caused by something else.
I train at medium intensity regularly (weight lifting and cycling). I used to use a lot of extra virgin olive oil, which now I have replaced with coconut oil and I eat a good amount of vegetables daily. In this 1.5 month, I gradually shifted my diet to be lower in carbs and focused on lower-GI carbs such as brown rice, increasing my intake of meat (or fish) and fat (kerry gold butter, coconut oil, bacon!). I am nowhere close to anything low-carb/ketosis.
I plan to make a new lipid-test and see what happens. If my LDL-C goes up again, I'll have to rethink whether I want to proceed on this road.
One question please regarding the GI of foods:
If I eat say GI60 pasta with ingredients that are low in GI, would the overall GI be lower? Ie. Is the blood sugar spike affected by the combo of foods you eat? Ie Is it better to eat pasta on its own and would eating pasta with olives, tomatoes etc lower it's sugar spike load?
As regards to this McDougall, any links? I think this is particularly concerning cause usually most dishes here in Malta are a combination of high GI foods (breads with meat, pasta with rabbit meat etc).
If you are really homozygous for ApoE4 (indeed the worst variant for lipid metabolism and Alzheimer's disease risk), those dietary changes are likely very detrimental to your long-term health and you should be much more concerned about the saturated fat content of your diet than about the glycemic load. I would urge you to cut back on butter and coconut oil, go back to olive/canola oil and to limit your intake of saturated fat from animal food (e.g. by choosing lean meats and low-fat dairy). Also, forget my advice about moderate alcohol consumption, as the HDL-boosting effect alcohol doesn't seem to work for ApoE4.
Indeed, you can be happy to have such a decent lipid profile as an E4/E4 carrier. Don't ruin it by falling for the LC/Paleo hype!
Btw. pasta, if cooked al dente, is not a particularly high-GL food. Nor is white rice if allowed to cool down (and reheated) before consumption. In Asian cultures, it is customary to cook large amounts of white rice in a rice pot and eat it troughout the day. Therefore, much of the rice will be enriched in resistant starch. I think this is an often neglected fact that (besides the fiber-rich, low protein dietarry pattern) may help to explain the beneficial outcomes of white rice in those cultures.
Hey timar, have you ever heard of Walter Kempner and the rice-diet? Probably the most effective and healing diet ever; consisted of white-rice, fruit, juice, and table-sugar( you know all those horrifying high-GI/GL carbs!!)... completely reversed metabolic-syndrome and well published back in the 1940s and 1950s. I would really love to hear your response on this.
Yes I have. And I have to say that the designation of "dietary prophets" such as Kemper (by the dogmatic low-fat vegans), or Price and Banting (by the WAPF/low-carb crowd) from the "heroic age" of modern sicence in the early 20th century is possibly the single most revealing hallmark of dietary ideologies, regardless of their substantial disparity. We have decades of high quality nutritional and medical science to rely on today, and must not mystify studies done three-quarters of a century ago. The work of those researchers, interesting as it may be from a historical point of view, is far from contemporary standards of scientific conduct and publishing which have been established for good reasons. This is not to belittle their pionieering work - their insights as well their mistakes - which has informed and advanced contemporary science.
I personally don't know a single lowcarber with a really great lipid profile. It's unphysiologic and no documented human culture ever did eat that way, also not in "paleo" times, as far as science is able to tell. That is enough for me to come to conclusions.
If your definition of low carb is <40%, this statement is factually wrong. There are quite a few hunter-gatherer cultures documented that consumed less than 40% carbohydrates (e.g. the Inuit or Massai). However, those cultures did so out of necessity - because they had little carbohydrates available. Notably, nearly all cultures having an abundant supply of carbohydrate-rich foods available seemed to have consumed around half of their caloric intake as carbohydrates.
