1
Ultra -processed foods make up more than half of the calories that Americans consume.
2
But they're actually quite dangerous for your health and potentially highly addictive.
3
And I'm not just talking about doughnuts and pizza here.
4
There are actually a lot of ultra -processed foods that we mistake for healthy ones.
5
I'm Mia DeGraff, I'm a health editor at Business Insider, and I'm going to be showing you how to tell what's an ultra -processed food from what isn't.
6
Processed food is something that has been altered in some way before it lands in your grocery cart.
7
So that's canned tomatoes or cheese or dried pasta.
8
Ultra -processed food is something that looks very unlike anything you would have in your kitchen at home.
9
It's had different ingredients added to it to make it more shelf -stable.
10
So those might be preservatives or sugar.
11
It's also gone through different processes like hydrogenation, which also help it last longer.
12
That's things like soda or candy bars or chips.
13
So the problem with ultra -processed foods on a nutritional level is
14
that the processes that they go through break down what's known as the food matrix within the food.
15
so many things that mean that they've deteriorated.
16
So if I'm at home, I slice up a potato and I fry it and turn it into chips.
17
The food matrix within that chip is going to be far more intact than if I buy a packet of chips.
18
Those chips have gone through so many different processes and have different chemicals that make them more shelf -stable, make them last longer.
19
As a result, they're lacking in the nutrients inside.
20
One of the biggest issues with ultra -processed food is the lack of fibre.
21
When you have a good amount of fibre in your body, your body naturally produces this hormone called GLP -1.
22
That is the hormone that weight loss drugs like Ozempic try to mimic.
23
They are literally called GLP -1 agonists.
24
not want to snack as much.
25
That's why ultra processed foods are linked with diabetes and heart disease and obesity.
26
A study in 2019 by the National Institute of Health provided
27
a bit of a watershed moment in terms of our understanding of ultra -processed foods.
28
So they had some people eating whole foods, some people eating ultra -processed foods.
29
They matched it perfectly for carbohydrates, fibre, sugars, everything, and you could eat as much as you wanted.
30
At the end of the study, they found
31
that the people on the ultra -processed food had eaten 500 calories more a day than the people eating whole foods.
32
That is, I cannot emphasize enough, a huge finding.
33
And it led the researchers to find that ultra processed foods do seem to incentivize you to eat more.
34
Other studies have found that ultra processed foods may be linked to anxiety and depression and sleep problems.
35
But the reality is you can't cut these foods out.
36
If you speak to a nutritionist, they will tell you that they eat ultra processed foods too.
37
They're unavoidable.
38
But the key is thinking about eating them in moderation.
39
So here are some foods that we often mistake for healthy, but they're actually ultra processed.
40
So let's start with juice.
41
It has vitamin C, antioxidants, polyphenols, these things which are all good for your heart and for your body.
42
processed and it's really lacking in fiber.
43
Once you've juiced, say, an orange, you're losing all of those fibrous materials that would be fortifying your body, and you're just extracting the sugars.
44
So you're getting a ton of glucose and a ton of sugar, and then that can cause your blood sugar to spike.
45
If you're looking for a healthy alternative to juice, fruit is really your best option.
46
That's where you're getting the original source of nutrients.
47
But above all, just drink it in moderation.
48
considered healthy because they're often made with oats and nuts and dried fruit and seeds.
49
These are all things which are really good for your heart and sometimes also good for your digestion.
50
The problem with granola bars is that they're often made with a ton of sugar.
51
If you look on the back of a granola bar label, very often they'll contain more than 15 grams of sugar.
52
That's four teaspoons.
53
So if you're going to eat a granola bar, what I would recommend is to look on the label and check that there is at least three grams of fiber,
54
at least five grams of protein, and less than 10 grams of sugar.
55
Alternatively, you could eat a handful of nuts, which is going to keep you fuller for longer and give you a burst of energy.
56
Or you could try and make your granola bars at home.
57
Another one is sports drinks like Gatorade.
58
The idea is that after a workout, or if you're a SIF, you're just thirsty for whatever reason, that you would drink, say,
59
a Gatorade, and it contains so many electrolytes that it will replenish the sodium in the water that you've lost.
60
The reason they're unfortunately not as healthy as we think is that these drinks often contain more sugar,
61
other sweeteners, and food coloring than anything else in the bottle.
62
to increased risk of diabetes and obesity.
63
If you're not an athlete or if you're not dripping with sweat after your workout, you probably don't need these drinks.
64
So drinking water and eating a nutritious meal is going to get you that same hydration.
65
Moving on, we have gluten free foods.
66
The issue with gluten free food is that, again, these are highly processed foods.
67
They often replace gluten with starchy ingredients like tapioca starch and rice flour and cornstarch, which can raise your blood sugar.
68
fast.
69
If you don't have a gluten sensitivity or you don't have celiac disease, there is no reason for you to avoid gluten.
70
If you're going to buy gluten -free foods, just look at the label and make a decision about how you want to consume it.
71
Look at how much sugar is in there, what kinds of sugar, what kinds of starch
72
and then make a decision about what else you're going to eat with
73
that gluten -free item that might help you to balance out the sugars
74
and those types of starch that are in that ingredient.
75
Cold cuts, like deli meats, are also ultra -processed.
76
Throw them in a sandwich that's a high dose of protein and zinc and iron,
77
but they are also very high in saturated fats and sodium.
78
In 2015, the WHO classified ultraprocessed meat as carcinogenic.
79
That includes cold cuts.
80
When you manufacture ultraprocessed meat, they inject a chemical called nitrites or nitrates to make it last longer and be more stable.
81
In your body, that converts into something called NOC, and that can damage the DNA and the cells in your bowel,
82
which can increase your risk of colorectal cancer.
83
So another food that's ultra -processed is plant -based meat replacements.
84
One of the benefits is
85
that they cut out a kind of chemical that's naturally occurring in something like red meat called Hymn, which can increase your risk of cardiovascular disease.
86
Just because something is plant -based, It can still be unhealthy.
87
Sugar, for example, is plant -based.
88
The other thing is that with a lot of these foods, they inject a lot of sodium to replicate the flavour.
89
So often they're very high in salt.
90
So here's how to decide whether you should buy an ultra -processed food or not.
91
Read the label.
92
Something that nutrition experts do is they follow the 5 /20 rule.
93
So that's less than 5 % of a bad thing, more than 20 % of a good thing.
94
You're looking for more fiber, less sodium, less added sugars.
95
Try to look at if there are chemicals that you don't recognize and be wary of buzzwords.
96
For example, something that says it's made with real fruit or made with real vegetables.
97
It might be majority sugars, but with a dusting of fruit or vegetable on top.
98
Also, there is a difference between certified naturally grown,
99
which is a regulated term and naturally grown. that doesn't mean anything.
100
The term organic, there are many benefits to organic foods, but just because something's organic doesn't necessarily mean it's healthy.
101
Organic sugar in a candy bar doesn't make that candy bar healthy.
102
And then lastly, just because something's natural, that doesn't necessarily mean anything.
103
The terms natural and healthy, they are not regulated.
104
These buzzwords are carefully designed.
105
They're part of a big marketing strategy for food companies.
106
Food companies spend, on average, $7 .5 billion a year advertising their products in the US.
107
That's $440 million every single month.
108
To put that in context, that is like making Avatar: The Way of Water, which is the highest budget movie ever made.
109
Once a month.
110
every month.
111
for the whole year.
112
So why are companies ultra -processing products?
113
First of all, it's cheaper.
114
You could replace butter with something like palm oil, sugar with something like corn syrup.
115
The other reason is that government interventions have made it really easy to make ultra -processed foods
116
and a little harder to scale up if you're a small business or a farm.
117
The government subsidizes corporations that produce ultra -processed food while private farms have to be privately run.
118
There might be a change coming in terms of how we're eating ultra processed foods in the US.
119
In 2025, the US government will be issuing new dietary guidance.
120
They do this every five years.
121
And ahead of that, they are conducting a pretty wide ranging study right now, looking at the chemicals used in ultra processed foods.
122
Big companies are watching this study and they're pretty nervous about it.
123
Depending on the findings, it may impact what Americans are told to eat.
124
If Americans swapped one ultra -processed food item from their meals every single day,
125
food companies' profits would drop by about 7 % on average, which is really significant.
126
If we just carried on doing that and started eating like Mediterranean's all the time, these food companies would probably fold.
127
Okay, I know I'm doing Gatorade and I actually want a sip of it right now.
128
I just saw it on my thing and I was like, argh!
129
Okay.
130
I think it's a good thing.
131
Okay, so...

Phương Pháp Shadowing Là Gì?
Shadowing là kỹ thuật học ngôn ngữ có cơ sở khoa học, ban đầu được phát triển cho chương trình đào tạo phiên dịch viên chuyên nghiệp và được phổ biến rộng rãi bởi nhà đa ngôn ngữ học Dr. Alexander Arguelles. Nguyên lý cốt lõi đơn giản nhưng cực kỳ hiệu quả: bạn nghe tiếng Anh của người bản xứ và lặp lại to ngay lập tức — như một "cái bóng" (shadow) đuổi theo người nói với độ trễ chỉ 1–2 giây. Khác với luyện ngữ pháp hay học từ vựng bị động, Shadowing buộc não bộ và cơ miệng phải đồng thời xử lý và tái tạo ngôn ngữ thực tế. Các nghiên cứu khoa học xác nhận phương pháp này cải thiện đáng kể phát âm, ngữ điệu, nhịp điệu, nối âm, kỹ năng nghe và độ lưu loát khi nói — đặc biệt hiệu quả cho người luyện IELTS Speaking và muốn giao tiếp tiếng Anh tự nhiên như người bản ngữ.
