1
What are you making, Big Granny?
2
Some healthy vegetable sandwiches.
3
Mmm, yummy!
4
Oh, what's this, Granny?
5
Oh, the bread had some greedy, mouldy stuff on it.
6
So I sliced the bad part and used the clean part.
7
Isn't it a smart move?
8
No, no, no. There is no such thing as a clean part of moldy bread.
9
What do you mean?
10
Let me explain that by answering a moldy question.
11
What if you ate moldy bread by accident?
12
Zoom in!
13
While it may seem like a sensible solution to cut away the mouldy part of the bread and consume the clean portion,
14
this can actually be a risky decision.
15
Yes, that's because although the mould itself may be easy to detect with the naked eye,
16
what we can't see is the vast network of underground roots called hyphae
17
that branch out throughout the bread and act as a means of transport for the fungus to extract nutrients from its surroundings.
18
So, it's always a wise choice to discard the entire piece.
19
But what about the other pieces of bread from the same loaf?
20
They look clean enough to eat, right?
21
Unfortunately, I wouldn't recommend that either.
22
You see, the visible The mold on the bread is actually just the tip of the iceberg,
23
as they are in reality the mold's reproductive structures called Sporangium,
24
whose job is to release thousands of spores which are essentially the seeds of the fungus.
25
So even if it looks clean on the surface,
26
the entire pack of bread could be home to countless fungi and spores just waiting to spread.
27
I know what you are thinking, aren't we eating fungi all the time?
28
For instance, yeast, a type of fungus is commonly used in baking pizza dough,
29
while Aspergillus oryzae is used in the fermentation of soy sauce.
30
Additionally, life-saving antibiotics are produced from Penicillium fungus.
31
So, what's the concern with the ones spread over pieces of bread?
32
Well, this is where it gets tricky because just like mushrooms,
33
some molds are harmless while others can cause serious damage to our health.
34
So with thousands of types of fungus contaminating our food, it's hard to say which ones are safe to eat and which ones are not.
35
But the vital question is, what if we accidentally ate some contaminated food with harmful species of fungi?
36
Well, if you just happen to have a bite or ate very little,
37
luckily there is nothing to worry about it as your body will deal with it.
38
Especially if you have a healthy immune system.
39
But if you ignore the warning signs and finish the entire loaf of bread,
40
then some molds like Penicillium Crustosum and Rhizophus Stolonyphor
41
which are commonly found on bread can cause some side effects such as nausea, vomiting and diarrhea.
42
Additionally, some people may have an allergic reaction to Penicillium, which can cause symptoms such as itching,
43
swelling and difficulty in breathing.
44
On the other hand, some moulds can produce harmful toxins that can cause serious health problems.
45
One such mould is Aspergillus, which is commonly found on bread.
46
Aspergillus can produce mycotoxins which can cause liver damage,
47
respiratory problems and even cancer in some cases.
48
So considering the risk factors, it's better to throw away the contaminated food and find something else to eat.
49
Also to prevent the growth of mold on bread, it is essential to store it in a cool and dry place.
50
Additionally, you should avoid buying food items that are past their expiry date or has visible signs of mold growth.
51
Trivia time!
52
Did you know the largest living thing on earth is a fungus known as the honey mushroom?
53
Yes, one of them covers almost 10 square kilometers of land in the Blue Mountains of the US state of Oregon.
54
It's sketching time!
55
The sketch of the day goes to Nidhi Gowde.
56
Hope you had fun today.
57
Until next time, it's me Dr. Binox, Zooming out.
58
Why are you throwing away mushrooms?
59
You said to throw away the fungus food.
60
Oh, never mind.
この動画は誰におすすめ？
英語学習を始めたばかりの初心者から、日常会話のスピーキング力を上げたい中級者まで。動画で英語学習を楽しみながら、科学的な内容を理解しつつ、実用的な表現を身につけたい人に最適です。特に、英語シャドーイング（shadow speech）の練習にも向いています。
覚えておきたい単語とイディオム
- moldy：カビの生えた。「moldy bread」は「カビの生えたパン」。
- hyphae：菌糸。カビの地下部分のようなもので、栄養を吸収する。
- tip of the iceberg：氷山の一角。表面に見える部分はごく一部で、大部分は隠れていることを表す。
- mycotoxins：マイコトキシン。カビが作る有害な毒素。
アクセントを正しくするコツ
この動画のスピーカーは明るく抑揚のある発音で話します。特に、「What if you ate moldy bread by accident?」のような疑問文では、最後の単語「accident」を上げることで疑問のニュアンスを出します。また、「the tip of the iceberg」の「iceberg」は「アイスバーグ」ではなく「アイスバーグ」と軽く発音し、アクセントを「ice」に置きます。英語スピーキング練習のためには、シャドーイング（shadowspeak）を繰り返し行い、リズムと抑揚を真似ることが重要です。
動画を見ながら、スピーカーの発音に合わせて即座に繰り返すシャドーイングは、発音や流暢さを上げるのに効果的です。特に、長い文の場合でも、息継ぎのタイミングを覚えることで、自然な話し方が身につきます。
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。
