1
Have you noticed you can watch 10 videos on nutrition
2
and get all kinds of contradictory advice
3
and come away more confused than you went in
4
and scared of every food and frustrated and you just feel like giving up.
5
Truth is, most nutrition content on social media is not that helpful.
6
It misses the point entirely.
7
What's worse, it trains your mind to ask the wrong questions.
8
And this is really tragic because nutrition applied correctly is unbelievably powerful.
9
Heart disease, cancer, diabetes, even dementia are massively impacted by your diet.
10
So getting the wrong advice isn't just a complete waste of your time, it also deprives you of life-saving information.
11
I've spent the last 30 years studying medicine, biology, and nutrition.
12
I've published my own scientific studies and I've had the privilege of interviewing some of the top researchers on the planet.
13
And in this video, I'll share with you exactly what my family
14
and I do and eat to achieve and maintain exceptional health.
15
I'll give you every tool you need so you can build delicious, healthy meals for your family.
16
And you can also spot bad nutrition advice, and you can finally stop wasting time with stuff that just doesn't matter.
17
I was recently writing this long article answering every frequently asked question on nutrition that you guys ask.
18
I'll link that below for you, but I realized it all boils down to five really simple principles.
19
And they're so incredibly powerful because they give you peace of mind
20
and we can cover them in minutes as you'll see
21
and by the end you'll be able to judge nutrition claims immediately if it's something serious or if it's just fear-mongering.
22
So here's the first principle.
23
A food is a combination of many different pieces of many different nutrients and components
24
packed together in a specific structure
25
and each of those building blocks can have a separate specific effect on your health for example
26
when you eat an avocado you're not just eating fat you're also eating all kinds of vitamins
27
and minerals and something called zeaxanthin which promotes eye health
28
and scopolitan which has anti-cancer activity and the list goes on and on.
29
An apple, a simple apple, is not just carbs.
30
You're also eating quercetin, which fights inflammation, and anthocyanins, which promote heart health, and all kinds of different vitamins and different types of fiber.
31
Even a food like olive oil, where most people think, no, that's just purified pure fat, right?
32
That's all.
33
No, it has a plethora of vitamins and carotenoids and other phytonutrients.
34
Oleocanthol is formed in olive oil and it has an anti-inflammatory activity.
35
And so it's a long list.
36
It goes on and on.
37
And so the realization here, the bottom line, is that the health effect of the whole food is the combination of the specific effects of each of these molecules.
38
And trying to guess the health effect of a food from
39
one isolated nutrient in a vacuum gets things wrong all the time.
40
This is like the blind man and the elephant.
41
You've heard that story, you've all heard it.
42
One blind man grabs the leg of the elephant and goes, an elephant is basically like a tree, it's a cylinder.
43
The other blind man grabs the ear and says, no, no, no, an elephant's this flexible round leaf almost.
44
The other grabs the trunk and says, no guys, elephant's basically like a hose.
45
It's a long bendy tube.
46
They all have a kernel of truth, but they're all missing the big picture.
47
None of them grasp what an elephant is.
48
This is such a simple principle.
49
You could explain this to a child literally, and I invite you to, and yet it's so powerful.
50
You grasp this, and so many dilemmas that puzzle millions of people online every day, they just dissipate away.
51
Should we all avoid beans and be scared of beans because they contain lectins?
52
Well, beans also contain minerals and different types of fiber and phytonutrients.
53
So what's the actual health effect of eating beans in human beings?
54
We have piles of studies documenting this we see better control
55
of blood sugar we see lower cholesterol we see weight loss
56
we see less heart disease we see longer lives in people who eat more beans
57
so i eat them all the time i eat them daily beans
58
and lentils and legumes like that and i give them to my family
59
because we actually know what the documented health effect is in
60
spite of all the speculation in reality some lactins can cause issues they can cause gastrointestinal distress
61
but the heat wipes them out.
62
So the normal processing of the beans, the cooking of the beans, already solves the problem.
63
So theory versus reality.
64
Should we avoid oats and all whole grains because they contain phytates, they contain glyphosate, they contain evananthromides,
65
they also contain a thousand other things, viscous fiber and phytonutrients and minerals.
66
What's the actual health effect in a human being eating them?
67
We have hundreds of studies doing this, giving people oats.
68
We see lower blood lower cholesterol, less body fat, lower risk of developing diabetes.
69
I eat oats all the time, almost every day
70
i give them to my family the children in my family eat oats all the time
71
because the health effects we see are overwhelmingly positive here's some
72
overnight oats with berries i just had the other day i didn't stress over the bad molecule
73
that might be in there i just enjoyed it
74
because i know what the overall health effect is should you cut carbs
75
or fat from your diet which one is good and
76
which one is bad is carb poison are fats good for you are fats bad for you these are the wrong
77
questions guys it completely misses the point of nutrition a whole macronutrient like carbohydrate or lipid
78
or protein is neither good nor bad it depends on the
79
food it comes in sources of whole carbohydrates like fruit or vegetables
80
or legumes we consistently see good health effects of those foods sources of highly refined carbohydrates like soda
81
or gummy bears or muffins we consistently see not
82
so good health effects of those foods
83
because these foods are about much more than just the carbs
84
that they contain it's a whole package the types of fiber
85
and the resistant starches and the phytonutrients and the minerals
86
and the vitamins in there a lot of these components are stripped away by the refinement process
87
and these building parts have a fundamental effect on how the food is processed in your body, how it's absorbed and digested,
88
and ultimately what health effect it has on you.
89
So when someone insists that you look at one molecule, always make sure to step back and look at the whole elephant.
90
And you can still eat a lower carb or a lower fat diet if you prefer, if you like it that way, if it's more sustainable for you,
91
just don't let people tell you these fairy tales that all fat is bad for you, all carbs are good for you.
92
That's nonsense.
93
Exactly the same for fats, of course.
94
Some fatty foods are good for you and some are not.
95
Internet debates on fats confuse millions of people.
96
It's endless because this simple concept is usually absent.
97
It's usually not understood.
98
Saturative fat.
99
The rivers of ink that have flown debating saturated fat.
100
Is saturated fat good or bad for you?
101
This is the wrong question entirely.
102
Completely misses the point.
103
Salmon, yogurt, kefir, dark chocolate, olive oil even.
104
These are foods that contain some saturated fat, and yet we consistently see positive health effects of these foods.
105
Butter, tallow, coconut oil in large amounts.
106
We're not talking about eating them here and there.
107
We consistently see concerning effects.
108
So saturated fat is neither good nor bad.
109
This is cartoonish.
110
It depends on a lot of different factors, the types of saturated fats and the package, the food it comes in.
111
So you want to look at the whole elephant.
112
Seed oils, people losing their minds, pulling their hair out over seed oils.
113
They have omega-6s.
114
They have hexane.
115
They have double bonds.
116
Canola oil is poison for you because it has erucic acid in it.
117
What's the actual health effect that we observe in human beings consuming canola oil?
118
We have a 30-minute video where we systematically went over every study.
119
We could find dozens of studies in human beings you see better blood work, lower cholesterol, triglycerides when they change is in a positive direction.
120
You see less liver fat, you see lower risk of dying of heart disease, lower risk of dying of cancer,
121
lower mortality overall, even in people cooking with canola oil, even after you adjust for obvious confounders like exercise or smoking.
122
So I buy canola oil.
123
I give it to my family.
124
It's one of the many fats that we eat.
125
Nobody has to eat it, but I'm not worried because the health effects are there.
126
Even the endless protein debates often miss this point.
127
Should we eat 0.8 or 1.1 or 1.45 grams per kilo body weight?
128
99% of people have no idea how many grams of protein they're eating.
129
And we have videos going over all those controversies.
130
But the bottom line is most Westerners are already getting plenty of protein.
131
They're getting all the protein they need even without counting grams of protein.
132
There's a lot of issues with the standard western diet and lack of protein is not one of them.
133
And these endless fights, the plant protein versus the animal protein, all this UFC style battle, you watch this stuff all day long,
134
you come away thinking that nutrition is about choosing a side, choosing a team.
135
We consistently see good health effects of fatty fish like salmon, fermented dairy like kefir for example,
136
great health effects, Legumes, like beans and lentils, nuts also.
137
We see better blood work, less heart disease, less inflammation on these foods.
138
And some are from plants and some are from animals.
139
So that doesn't explain it.
140
When I sit down to eat, I'm not stressing out and losing sleep over the amount of protein in my diet.
141
I know I eat a diverse diet that includes a number of protein-rich sources and they're health-promoting.
142
That's the main thing for me even fiber
143
which the evidence for health benefits of fiber is one of
144
the strongest evidence bases in nutrition we see less heart disease less cancer less diabetes
145
but really it's the foods the fiber comes in
146
that natural package right that's what we're talking about it's the health effect of those foods not necessarily
147
the effect of any food with fiber.
148
Because if we forget this whole elephant concept, then we get gamed by the food industry selling us their sugary foods saying,
149
hey, it contains fiber, we threw fiber in there.
150
All of this, all of this principle doesn't mean that nutrients don't matter, right?
151
That humongous article I wrote goes over dozens of nutrients one by one
152
and best sources and how to make sure you're getting enough.
153
But the bottom line is at the end of the day, don't forget, step back, look at the whole elephant.
154
The beautiful thing is how simple this principle is, how easy to grasp.
155
You don't need to be a scientist and it's so powerful.
156
We constantly hear from viewers saying how they reverse diseases
157
and maintain fantastic blood work and they have peace of mind eating
158
and they don't get swept away by the fear-mongering on social media anymore.
159
I remember one viewer who messaged me, I'll never forget that she was terrified of her lunch.
160
She was literally petrified of every food because one influencer told her carbs are poison.
161
The other said fats are bad for you.
162
The other said dairy is toxic.
163
The other said oils are a no-no.
164
She had nothing left.
165
She just started going through some of our simple videos explaining these concepts.
166
She instantly understood that these are imaginary monsters.
167
This is made up stuff.
168
and she started to relax and enjoy her food and eating a healthy diet without being in constant panic.
169
Okay, just with this first principle, you're already way harder to fool than almost everybody on the internet, but this next principle trips up a lot of smart people.
170
Second fundamental principle, some people have specific conditions and specific intolerances and they need to personalize their diet.
171
That doesn't necessarily apply to all of humanity.
172
You'd be blown away by how much fear-mongering and confusion on social media depends on you not understanding this.
173
Some people are intolerant to gluten.
174
There are legit conditions like celiac and others.
175
We have videos covering that, how to diagnose and how to navigate that for people who have those conditions, but that doesn't apply to 99% of humans.
176
Some people form kidney stones and a subset of those form kidney stones made up of oxalates.
177
For those individuals, there are very specific strategies.
178
We've covered all those before.
179
But this doesn't apply to the vast majority of humans.
180
Do you know how much I worry about oxalates when I sit down to eat?
181
Zero.
182
Never think about them.
183
Because I'm not a stone farmer.
184
In my family, we're not stone farmers.
185
So that's one thing we don't need to worry about.
186
Here's a beet salad with walnuts and greens I had the other day.
187
Did I measure the oxalates in this?
188
Didn't think about it once.
189
Just enjoyed it.
190
Some people have GI conditions.
191
IBS, irritable bowel, or IBD, inflammatory bowel.
192
Those people need to personalize.
193
There are strategies for that.
194
A lot of those intolerances can sometimes be reversed.
195
But the point is, those limitations and personalizations don't apply to a healthy individual.
196
Other things that also vary a lot person to person and cause a lot of confusion.
197
Eggs.
198
Do eggs raise your cholesterol or not?
199
People can't get a straight answer.
200
That's because there is no one answer.
201
Some people, when they eat cholesterol in their diet like eggs, their blood cholesterol level skyrockets.
202
But for most people, that's not seen.
203
Most people, they see a modest increase of about seven points in your cholesterol level.
204
So it makes sense to personalize for your biology, for your needs.
205
Some people are very salt sensitive.
206
They eat more sodium and their blood pressure goes through the roof.
207
Others are more salt tolerant.
208
Varies a lot. So personalize.
209
Eat to your blood work eat to your test.
210
Just a great mindset.
211
Blood sugar spikes, the glucose spikes, people are pulling their hair out over the spikes.
212
Some individuals have health conditions where their glucose response to a meal is not normal.
213
Typical example is someone with diabetes.
214
We have a whole video explaining strategies for those individuals, but this does not apply to healthy people.
215
How come we have millions of people terrified of glucose spikes, of oxalates, of gluten, and then the most knowledgeable people on earth on these topics
216
that i talk to all the time that study this for a living
217
they're not worried about it they just sit down
218
and enjoy their food i got my phd for work on aging
219
and nutrition i've read thousands literally thousands of studies on nutrition
220
when i sit down to eat with my family we're not stressing out over oxalates
221
or glucose spikes we're just enjoying food a lot of fear-mongering
222
out there relies on you not understanding these basic principles and fearing things that don't apply to you.
223
Why?
224
Because fear is a very powerful trigger to get you to click stuff and swipe your credit card.
225
Okay, the glucose spikes, panic, and stampede also misses another fundamental principle of biology and nutrition.
226
And this is our third principle that we're going to cover.
227
This confuses so many people, including smart people, and it's It's so simple.
228
Your body is in constant motion, constant changes.
229
We call it homeostasis.
230
During exercise, your blood pressure goes up.
231
Your heart rate goes up.
232
After you eat something with fat in it, those fats go into the bloodstream.
233
Your triglycerides go up.
234
After you eat something with carbohydrate, those sugars go into your bloodstream.
235
Your blood sugar goes up.
236
These are examples of temporary changes.
237
We call them acute changes.
238
This is not disease.
239
It's not the same as disease.
240
The problem is continuous exposure to these issues what we call chronic exposure.
241
Your blood pressure is high all the time.
242
You're sitting down and your blood pressure is through the roof.
243
That's hypertension.
244
That's a problem.
245
Your triglycerides are high all the time, even when you're fasted.
246
Your blood sugar is high even when you're fasted.
247
That's an issue.
248
Don't fall for this switcheroo, for this cheap trick.
249
A blood test going up after an activity
250
or during an activity is not the same as
251
that blood value being high all the time in the context of a disease.
252
Fourth principle of nutrition.
253
This explains so much.
254
You grasp this.
255
A lot of the dilemmas just fade away.
256
Compared to what?
257
Everything in nutrition is instead of what?
258
Stop thinking of foods as good and bad, as superfoods and poison.
259
That's not how this works.
260
And that type of mindset makes you an easy target.
261
Because any food can be made to look good or bad depending what you compare it to.
262
I can make ice cream or bacon or anything look good by controlling what I'm comparing it to.
263
The saturated fat debates confuse people with this all the time.
264
Oh, I found a study where more or less saturated fat doesn't make a difference, so it's all a wash.
265
Compared to what?
266
Large studies have shown this many times.
267
We've known this for many years.
268
You compare butter to white bread or muffins, you don't see much of a difference in terms of heart disease.
269
Compare butter to olive oil, you see less heart disease, or to brown rice, or to steel cut oats.
270
There you see the difference.
271
Fifth principle of nutrition, and this probably gives people the most peace of mind.
272
It is so liberating.
273
Your health is determined by the foods you eat consistently, not something you do occasionally.
274
So it's not about being perfect.
275
It's about most of your diet being healthy foods.
276
I went to a family picnic last week and I had a bunch of potato chips.
277
Am I worried about that?
278
Not really because I do that once in a blue moon
279
and 99% of my foods in my diet are really healthy
280
Have the ice cream on the weekend with your kids have the piece of candy once in a
281
while The problem is eating that stuff day in
282
and day out The real currency of nutrition is dietary pattern more
283
so than isolated foods And the diet we have the most evidence for is something called traditional Mediterranean diet
284
We see less heart disease, less diabetes, less of some types of cancer, less mortality, even better mental health.
285
What is the traditional Mediterranean diet?
286
It's basically fruits and vegetables, legumes, whole grains, olive oil, fish and seafood, some dairy, lean meats, and low in ultra processed junk foods.
287
So basically all the foods and principles we already covered, right?
288
It all comes full circle.
289
This is a general reference.
290
It's not a strict menu.
291
It's not shackles.
292
you can and you should personalize it
293
if you don't like one of those foods don't eat it
294
if you have an intolerance take it out
295
if you want to eat a low carb or low fat
296
or a vegetarian version you can do
297
that once you understand it's not about the name of the diet it's about the fundamental principles
298
that we covered then you can tweak any dietary pattern
299
and still eat a healthy diet
300
but very important caveat make sure to fill any nutrient gaps
301
most healthy adults on a diverse diet get all the nutrients they need macronutrients micronutrients vitamins minerals
302
and they don't need supplements but
303
if you're on a vegan diet for example you need a source of b12 if you don't have
304
iodine in your diet a lot of people don't eat fish
305
or seafood a lot of people are moving away from dairy a lot of people are cutting back on salt
306
and those are the main source of iodine
307
make sure you have some iodine in there or supplement
308
and as we said eat to your blood work eat to your tests, get blood analysis, measure blood pressure,
309
look in the mirror, and adjust and personalize based on that.
310
Very powerful.
311
This moves you away from the need to memorize every nutrient and knowing every study.
312
Someone scares you with an isolated molecule.
313
You ask, what does the whole elephant look like?
314
Someone shows you a spike after eating.
315
You ask, does this matter long term?
316
Is this specific to a disease setting that I don't have?
317
And you can eat a treat once in a while
318
and have peace of mind
319
because you understand your health is determined by what you do
320
consistently guys i wrote this behemoth article covering every frequently asked question
321

322

Improve Your English Vocabulary: Diet, Health, and Nutrition
Daily ConversationWorking Adults
Per chi è questo video?
Questo video è perfetto per gli studenti di inglese a livello intermedio o avanzato che vogliono imparare l'inglese con i video e migliorare sia la comprensione auditiva che la pronuncia. Ideale per chi cerca consigli pratici e vuole approfondire argomenti concreti, come la nutrizione, mentre esercita la lingua. I principi semplici spiegati rendono il contenuto accessibile, anche se hai poca esperienza con argomenti scientifici.
Parole e modi di dire da "rubare"
Ecco alcuni espressioni standout dal video, utili per arricchire il tuo vocabolario:
- Contradictory advice: Consigli contraddittori. Esempio: "I video su Instagram spesso danno contradictory advice sulla nutrizione".
- Fear-mongering: Spaventare per creare paura. Esempio: "Molti articoli usano il fear-mongering per vendere prodotti".
- Plethora of: Una quantità enorme di. Esempio: "L'olio d'oliva contiene un plethora of sostanze salutari".
- Kernel of truth: Un nucleo di verità. Esempio: "Le sue parole hanno un kernel of truth, ma non dicono tutto".
Come migliorare la pronuncia inglese con questo video
Per esercitarti con il shadowing (tecnica di ripetizione immediata), segui questi passaggi: ascolta un frammento di 5-10 secondi, pausa e ripeti subito, cercando di imitare l'intonazione e il ritmo del speaker. Il tono calmo e chiaro del narratore lo rende perfetto per principianti. Focus su sound come /θ/ in "truth" o /ʌ/ in "nutrient" – le parole difficili sono spesso quelle con consonanti sorde o vocali corte. Usa un shadowing site per registrare te stesso e confrontarti con l'originale: noterai come migliorare la fluidità. Ricorda: il shadow speech non è solo ripetere, ma capire il senso mentre parli. Con questo video, potrai anche esercitare la comprensione di argomenti complessi in modo naturale.
Non ti preoccupare se all'inizio è difficile: la pratica regolare con video come questo ti aiuterà a migliorare la pronuncia inglese e a sentirti più confidente nel parlare. Iniziamo!
La grammatica di questo video
Le strutture che chi parla usa di più, con le parole esatte del video:
| Struttura | Nel video |
|---|---|
| Present perfect have/has + participio passato — un’azione passata che conta ancora adesso | Have you noticed · I've spent · I've published |
| Forma passiva be + participio passato — conta ciò che accade, non chi lo fa | is formed · are stripped · is processed |

Cos'è la tecnica dello Shadowing?
Shadowing è una tecnica di apprendimento delle lingue supportata da studi scientifici, originariamente sviluppata per la formazione dei traduttori professionisti e resa popolare dal poliglotta Dr. Alexander Arguelles. Il metodo è semplice ma potente: ascolti un audio in inglese di madrelingua e lo ripeti immediatamente ad alta voce — come un'ombra che segue il parlante con un ritardo di solo 1–2 secondi. A differenza dell'ascolto passivo o degli esercizi di grammatica, lo shadowing costringe il tuo cervello e i muscoli della bocca a elaborare e riprodurre simultaneamente i modelli di discorso reale. La ricerca dimostra che migliora significativamente la precisione della pronuncia, l'intonazione, il ritmo, il discorso connesso, la comprensione dell'ascolto e la fluidità del parlato — rendendolo uno dei metodi più efficaci per la preparazione alla prova di speaking dell'IELTS e per la comunicazione reale in inglese.
