דיון זרעי צ'יה \Salvia hispanica

[Zosed]

Chia seeds contain -

* 2 times the protein of any other seed or grain
* 5 times the calcium of milk
* 2 times the amount of potassium as bananas
* 3 times more iron than spinach
* and of course, copious amounts of omega-3 and omega-6. 20% of Chia seed is Omega 3 oil and 7% of its oil is Omega 6 oil. This is the perfect balance of essential fatty acids.

A 15g serve of chia seeds contains almost zero sugars.

למישהו יש נסיון עם המוצר הזה? נעשו מחקרים בנושא הספיגה של הדבר הזה?
אז מה אתם אומרים לזרוק את השמן דגים ולהתחיל לקחת את זה? או שזה עוד בולשיט

וזה מה שיש ללורן קורדיין להגיד בנושא:

I stand by my statement that phytic acid impairs absorption of divalent ions in a dose-dependent manner. This data is unassailable, and has been recognized in the nutritional community for more than 50 years. Hence, much of the calcium, iron, zinc and magnesium which on paper appear to be present in chia seeds are not available for absorption in vivo. Consequently, chia seeds are not good sources of these nutrients in living humans. In a typical western diet in which nutrients come from a variety of foods, particularly animal foods, these nutritional shortcomings in chia seeds likely are of little consequence. However, if chia seeds are consumed as staple foods, comprising a substantial percentage of the caloric intake, overall nutrition would suffer similar to other human populations in which seeds (cereal grains, legumes) comprise more than half of their daily energy1.

I also stand by my previous statement:

A recent review of all human chia supplementation studies concluded: "There is limited evidence supporting the efficacy of Salvia hispanica for any indication; thus far, only two clinical studies have examined the effects of Salvia hispanica on cardiovascular disease (CVD) risk factors (including body weight). One study showed some effects on some CVD risk factors, while the other did not. Neither study showed any effects of Salvia hispanica on weight loss" 2.

Despite animal data showing certain positive health effects of chia seed consumption, (which I listed in my article – see volume 6, issue 7 of this newsletter), randomized controlled human trials have been unable to replicate these results. Consequently, until further clinical trials are conducted for humans, no good experimental data can support the notion that chia seed consumption has therapeutic value.

The preliminary data in both humans and animals suggesting pro-inflammatory and pro-allergic effects with chronic high level chia seed consumption are problematic and should not be ignored. The study showing dramatic increases in IgE in animals was not statistically significant because the sample size was so small that it lacked statistical power to demonstrate a treatment effect. This is an experiment that could easily be replicated with an “n” of 10 to 20 animals. If Dr. Coates is so confident that "Until there are definitive studies that prove chia is unhealthy to consume, which I do not believe will ever be the case, . . .", perhaps he should replicate this experiment with a larger sample size.

I remember a similar circumstance a few years back when a number of well known acne researchers confidently stated that "diet had virtually nothing to do with acne." Research from our laboratory first proposed that diet was the primary environmental trigger of acne; further we outlined the mechanisms involved3, 4. Our work was later confirmed in a number of recent randomized controlled trials5, 6.

Finally, in humans ALA by itself has little or no anti-inflammatory effects. It is the hepatic conversion of ALA to long chain omega 3 fatty acids (20:5n3 and 22:6n3) which are anti-inflammatory. Because less than 5% of ALA is converted to 20:5n3 and less than 0.5% is converted to 22:6n37, a better strategy than "to continue heaping chia seeds on most everything that I eat, including eggs, salad, and meat," would be to eat 100 grams of salmon every other day.

בקיצור, זה די דומה לזרעי פשתן. לא טעים ולא כל כך מועיל.
