1
This is what sausage in 1940 was like.
2
Look how few ingredients there are.
3
And this is what sausage in 2026 is like. Are you sure?
4
I've been seeing a lot of these like comparison posts where it's like, you ate that and you were fine as a kid.
5
Wrong.
6
You actually ate this version, which has fewer ingredients, and this version has more ingredients.
7
And if there's more ingredients, that means there's more bad things.
8
And that means it's bad for you.
9
As important as it is to know food science, it's also important to know history.
10
Because in 1967, this is when the FDA required pretty much everything, not just things that have health claims,
11
but everything needed to provide a list of ingredients.
12
So it's possible that there were plenty of additives and things in our food products that were not disclosed.
13
I'm not saying that's true across the board because the 1938
14
Federal Food, Drug, and Cosmetics Act helped with this quite a bit.
15
But a lot of these posts that fear monger you into thinking
16
that just because you ate fewer ingredients in things
17
when you were a kid means it's better for you is sometimes not even accurate.
18
Plus, in addition to this, this infographic in particular picks 1940.
19
40. Brother, they were making sausage out of acorns at that point.
20
They were in the middle of war rationing.
21
Also, you can just tell this infographic is generated by AI.
22
And just because something has more ingredients in it does not make it worse for you.
23
Like, that's just not how things work.
24
In addition to that, sausage and deli meats require a lot of additives
25
and preservatives to prevent things like listeria e coli basically a sausage
26
or a deli meat is a perfect breeding ground for certain types of foodborne illness
27
and certain microbes because you know if the salt isn't high enough
28
and you know consumers are demanding lower
29
and lower sodium now you got to add other things in there to basically reduce the what the water activity

シャドーイングとは？英語上達に効果的な理由

シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
