[從副食品開始打造寶寶的不失智人生]
咀嚼可以刺激腦部,讓腦部發展(智力)較好、老年人失智的風險降低等等好處,都已經有非常多的研究證實。
#東京醫科齒科大學 上個月發表了一項實驗室成果: 成長期的咀嚼刺激低下,導致海馬迴神經細胞變化,與記憶學習機能障礙的發生有關。他們找來兩批實驗幼鼠,在離乳時期(副食品時期),實驗組給予磨成粉末狀的飼料;對照組給予一般的固型飼料。持續直到他們都長大成鼠。結果發現,實驗組(吃粉狀飼料副食品鼠,缺乏咀嚼刺激)的顏面骨以及咀嚼肌的成長受抑制之外,記憶與學習機能也顯著較差。他們進一步將主司記憶學習機能海馬迴解剖來看,發現神經突触(Synapse)以及腦源性神經營養因子( BDNF) 都低下,神經細胞也減少。接下來團隊希望能夠進行人體的研究,解明人類失智症且尋找新型治療法的希望。研究成果發表在「Journal of Dental Research」。
過去已經有諸多統計的結果揭示了腦力與記憶力可以靠鍛練來延緩衰退的速度,甚至可以透過刺激來活化腦力。日本東北大學醫學系與牙醫系也曾以殘存牙齒數來推斷咀嚼刺激與腦活化的關聯:殘存牙齒越少的高齡者,海馬迴容積量越有減少的情形。因為缺少牙齒代表相對來說咀嚼的刺激較少。
現在這一份東京醫科齒科大學的實驗研究,更顯明的咀嚼刺激的缺乏對我們腦部的負面影響。而且這個影響從小時候就開始了!
所以當媽媽們的在在意 #副食品 的營養是否均衡之外,給予小孩適當的 #咀嚼刺激 也是很重要的一個考量因素喔! 即使一匙一匙的餵食相當煩人,小孩吃的滿身滿地都是收拾起來也很煩人,但這些刺激對他們未來幾十年後的人生都有不可磨滅的影響! 從副食品開始,奠定小孩的不失智人生吧!
註記:
神經突触(Synapse): 神經細胞之間溝通的重要構造。腦部的神經細胞以突觸的形式互聯,形成神經網絡。這對於感覺和認知的形成極為重要。
腦源性神經營養因子( BDNF): 腦內合成的一種蛋白質,廣泛分佈於中樞神經系統內,在中樞神經系統發育過程中,對神經元的存活、分化、生長發育起重要作用,並能防止神經元受損傷死亡、改善神經元的病理狀態、促進受損傷神經元再生及分化等生物效應,而且也是成熟的中樞及周圍神經系統的神經元維持生存及正常生理功能所必需。

THE MOST DANGEROUS PET CHEW EVER: RAWHIDE!
How can one of the most popular chew sticks on the planet be so dangerous for your pets, you ask? I mean, most dogs chew on rawhide for hours on end, and not only does it keep them busy, but they seem to last forever.
Well if you understood what it took to make this toxic “raw” leather stick, you would quickly understand what the problem is.
Aside from the horror stories circulating all over social media these days, of pets needing emergency surgery after consuming rawhide, the majority of pet parents today, especially the newbies, believe that this chew is some sort of dried up meat stick. Let me debunk that myth right away!
A rawhide stick is not the by-product of the beef industry nor is it made of dehydrated meat. Rather, rawhide is the by-product of the “Leather Industry”, so theoretically it is a leather chew. Sounds awesome, right?
“Producing rawhide begins with the splitting of an animal hide, usually from cattle. The top grain is generally tanned and made into leather products, while the inner portion, in its “raw” state, goes to the dogs.” TheBark.com
So, how does this leather, which is conveniently rolled up into pretty shapes, actually get made into those rawhide chews?
Follow along my friends and I will enlighten you on how this hide travels through a leathery process where it transforms from hide to a not-so beautiful, colorful, chew stick. Here is a paraphrased tutorial that was explained by the whole dog journal several years back:
STEP 1: Normally, cattle hides are shipped from slaughterhouses to tanneries for processing. These hides are then treated with a chemical bath to help “preserve” the product during transport to help prevent spoilage.
(No one wants to purchase a black, spoiled rawhide stick!)
Once at the tannery: the hides are soaked and treated with either an ash-lye solution or a highly toxic recipe of sodium sulphide liming. This process will help strip the hair and fat that maybe attached to the hides themselves.
(No, no one wants to see a hairy hide…)
Next on this glorious journey, these hides are then treated with chemicals that help “puff” the hide, making it easier to split into layers.
The outer layer of the hide is used for goods like car seats, clothing, shoes, purses, etc. But, it’s the inner layer that is needed to make the rawhide. (Oh and other things like gelatin, cosmetics, and glue as well!)
STEP 2: Now that we have the inner layer of the hide, it’s time to go to the post-tannery stage! Hides are washed and whitened using a solution of hydrogen peroxide and/or bleach; this will also help remove the smell of the rotten or putrid leather. Bonus!
(Research also shows that other chemicals maybe used here to help the whitening process if the bleach isn’t strong enough.)
STEP 3: Now it’s time to make these whitened sheets of this “leathery by-product” look delicious! So, here is where the artistic painting process comes in.
“Basted, smoked, and decoratively tinted products might be any color (or odor) underneath the coating of (often artificial) dyes and flavors. They can even be painted with a coating of titanium oxide to make them appear white and pretty on the pet store shelves.” - whole-dog-journal.com
“…the Material Safety Data Sheet reveals a toxic confection containing the carcinogen FD&C Red 40, along with preservatives like sodium benzoate. But tracking the effects of chemical exposure is nearly impossible when it’s a matter of slow, low-dose poisoning.”– thebark.com
Ok, now that these hides have been painted, it’s time for the final process.
STEP 4: Getting it to last forever!
Because the FDA does not consider these chews to be food, really it’s a free for all when it comes to the manufacturers of these leather strips, and the products they may want to add to these chews, to get them to last forever. Any sort of glue can be added here to get these bad boys to never come apart.
When tested: Lead, arsenic, mercury, chromium salts, formaldehyde, and other toxic chemicals have been detected in raw hides. So it’s safe to say that any sort of glues can be used as well!
Finally, it’s time to package and attach all the glorious marketing labels to the product.
Check out the fine print warning that’s attached with some of these rawhides:
“Choking or blockages. If your dog swallows large pieces of rawhide, the rawhide can get stuck in the esophagus or other parts of the digestive tract. Sometimes, abdominal surgery is needed to remove them from the stomach or intestines. If it isn’t resolved, a blockage can lead to death.“
(Oh, how lovely…)
And there it is! It’s now ready to be shipped to store shelves where it can be purchased for our loving animal companions.
How do proactive veterinarians feel about these chews?
Here is world-renowned veterinarian Dr. Karen Becker's take on the matter:
“The name ‘rawhide’ is technically incorrect. A more accurate name would be processed-hide, because the skin isn’t raw at all. But the term “rawhide” has stuck.
Rawhide chews start out hard, but as your dog works the chew it becomes softer, and eventually he can unknot the knots on each end and the chew takes on the consistency of a slimy piece of taffy or bubble gum. And by that time your dog cannot stop working it -- it becomes almost addictive.
At this point, there’s no longer any dental benefit to the chew because it has turned soft and gooey, and, in fact, it has become a choking and intestinal obstruction hazard.“
P.S. Ready for the jaw dropper?
An investigation by Humane Society International stated in their report, “In a particularly grisly twist, the skins of brutally slaughtered dogs in Thailand are mixed with other bits of skin to produce rawhide chew toys for pet dogs. Manufacturers told investigators that these chew toys are regularly exported to and sold in U.S. stores.” – dogingtonpost.com
