What I Look For in Every Ingredients List (And Why You Should Too)

Video transcription : What I Look For in Every Ingredients List (And Why You Should Too)

Do not be fooled into buying gluten-free stuff thinking that, "Oh, this is a healthy food. Oh, this gluten-free cupcake is super good for me." No, no, no.

Hello angels, and welcome back to the glucose goddess show. I'm Jessie Inchauspé, a French biochemist. And I want you to understand your health and your body so you can feel really well. And I also want you to know how to navigate the very complicated, confusing food landscape that we live in today. Like when we go to the grocery store, it's complicated. We're not sure what's healthy, what's not healthy. When we turn the packet over, we're not sure what to look at to make the right choice. So today I'm going to give you all of my top tips to be able to understand really really well what the back of a package hides from you so you can pick the right stuff for you and your family. So let's get started.

The first thing you need to know is that when you look at the packaging and you turn it over, the list of ingredients is a really good place to start looking. And in the list of ingredients, you should know that the ingredients are ordered by weight. So the earlier in the list an ingredient is, the more quantity of that ingredient in the food. For example, if the ingredients list says, I don't know, um, sugar, apple juice, and what could be a random thing? And high fructose corn syrup. If that's the ingredients list, the sugar is going to be the one present in the highest quantity, then the apple juice, and then in a smaller quantity, the high fructose corn syrup. So, it goes in descending order.

Now, here's my first tip. If sugar is in the first five ingredients on the ingredients list, the food you're looking at is dessert. I don't care if it says breakfast cereal. I don't care if it says it's a healthy protein bar. There's going to be so much sugar in that product that it's not going to be so good for you. And you can totally buy it. You should just know that's a dessert. That's not something that I should be having first thing in the morning or on an empty stomach.

Now, here's where it gets complicated. Food manufacturers use many different names to say sugar. They don't just say sugar. There's a long, long list of ingredients that don't sound like sugar, but that is sugar. I'm going to give you a few small examples here, and then you can download the PDF in this episode. You can download it in the description below. It's going to give you all the names of sugar and also all the other tips that we're going to talk about in the rest of this episode.

So, a few examples of the many names of sugar on an ingredient list. Agave nectar, cane sugar, caramel, corn syrup, evaporated cane juice, fruit juice, galactose, glucose, golden sugar, golden syrup, honey, icing sugar, maltodextrin, maltose, maple syrup, panela sugar, rice syrup, sucrose, turbinado sugar. There are many, many names here.

And one special mention goes for you guys know I've been doing my glucose hacks religiously. They are the foundation of my dietary habits. But adding the molecules and anti-spike has really allowed me to get to the next level in a few areas. One, bloating. I didn't even know that I would get bloated. With Anti-Spike, I'm like, "Oh, I used to get bloated. I feel so much better now." Two, energy levels. Super consistent. Eagle energy all day. And three, cravings for sugar. I love sugar. I want to eat chocolate all the time. And Anti-Spike has given me a feeling of having a total superpower when it comes to my sugar cravings. I don't feel controlled by them anymore at all. It's truly amazing. And I know that these natural molecules are going to help my long-term fasting glucose and fasting insulin levels, which is so key to physical and mental health and to healthy aging. So, go to anti-spike.com to see all the science behind these ingredients, to see testimonials from thousands of people who've tried it, and to order your own Anti-Spike formula bottle and try it for yourself.

And one special mention goes for fruit juice, fruit juice concentrate, fruit puree concentrate, and pressed fruit. These are names of ingredients that you might find in an ingredients list. And the thing is, because it says fruit in them, they sound healthy, right? They sound like they're good for you. But actually, they are just sugar. Because sugar is sugar, no matter the source that it came from. So if to make a product a manufacturer has extracted sugar from say I don't know strawberries thrown away all the fiber in the water in the strawberries extracted the sugar concentrated in concentrated it sorry and put that in their fruit product. It's exactly the same thing as if they had taken just plain table sugar. These names can be confusing but if you see something with fruit in the ingredients list it's going to be sugar.

So let me give you an example. What I'm pulling up right now is the ingredients list of a fruit smoothie. I'll read them out, too. Half a pressed apple, half a crushed peach, 13 pressed grapes, 11 crushed raspberries, and a dash of lemon juice. Now, these first four ingredients are just sugar because fruit juice is just sugar.

So, that's the first tip. Look at the ingredients list. If sugar is in the top five ingredients, it's going to be dessert. It's fine to have it, but it is dessert. And also remember, sugar can come in many different names. You have to be a detective and know how to spot it. But it gets easier as you get some practice. And if you see anything that's like a fruit puree, fruit juice concentrate, that is also sugar. So remember, if it's there, it comes from fruit and it's in the top five ingredients, that food is dessert.

Okay. Next, what do we look at? We look at the nutrition facts on the back of a packaging. Now, the good thing about the nutrition facts is that there's not much hiding that anybody can do here. These are facts. There's some edge cases where some sugars can be categorized as fibers, but for our purposes, this is the place where you'll find the most truth.

So, one thing about serving sizes, sometimes manufacturers will make their serving sizes very, very small so that in the nutrition facts it doesn't look so bad. So for example, you might see a cookie box and the serving size might be one cookie, but like who just eats one cookie? So you should not look at these numbers and the calories, etc. based on their serving size. What we should be looking at is the ratio of different lines of this table to each other. This is what holds the objective evidence that you want to get really good at deciphering.

So skip right past the calories line. Actually, that's the next thing you should do. Don't look at calories because two foods can have the exact same number of calories but have vastly different molecules in them and vastly different impacts on our health. For example, an avocado and a donut can have the same number of calories. But the avocado is going to help your health, keep you feeling full, satiated, encourage your body to burn fat for fuel, and the donut is going to make you sick and inflamed and have glucose spikes and cravings.

So, calories, even though I know it's the biggest number on the box, calories are not what you should be looking at. If you take away anything from today's episode, this is kind of the most important point. The calories line should be ignored. I'm going to teach you how to get down to the details where the truth actually lies.

So, the first place to look is the total carbohydrates line. Then, the second place to look is the dietary fibers line. And I want you to find products that are going to be as close as possible to having for each five grams of carbs at least one gram of fiber. Why? Because that's a ratio we find in nature in most fruits. For example, for every five grams of carbs, there's at least one gram of fiber. And this is good because carbs are starches and sugars. They turn to glucose when we digest them. They create glucose spikes. And fibers are protective.

So the more grams of fiber you have for each five grams of carbs, the smaller the glucose spike in that food. So let's say you're trying to buy some cereal and you want to compare two cereal boxes to see which one is going to be better for you. So let's look at the nutrition facts. We have cereal number one, 25 grams of total carbohydrates and 14 grams of dietary fiber. So for every five grams of carbs, there's about three grams of fiber. This is a really good ratio.

Now, if we look at cereal number two, we have the same amount of carbs in there, but the dietary fiber is much much lower. And all of the other stuff in the nutrition facts are pretty equal. So, really, this is a really good comparison. But, as you can see in cereal number two, there's not even one gram of fiber for each 5 g of carbs. There's less than that. So, cereal number one is a much better option for your health and for your glucose levels.

Now, if this seems complicated and you're not sure about how to do the ratios and stuff, download the PDF in the description of this episode. I will go step by step about how you do it. You can even take out your, you know, your calculator on your phone and just calculate on the go. I explain to you exactly what to do so you get to that ratio and you are able to compare two boxes of cereal, of any other dried goods like some cookies, some bread, some crackers and see which ones are going to cause a smaller glucose spike.

Now, another thing to look at, of course, is the amount of protein in a product. So, here you look at the protein line. And the higher the protein, the better essentially because protein is good for us. It keeps us satiated. It reduces our glucose spikes. It builds our muscles. It gives our body the amino acids that it desperately needs to stay alive and to thrive. So, protein is really important. The higher the better.

So, that's basically what I do when I look at a food package. First of all, I look at the ingredients. If there's sugar in the top five ingredients, I'm like, that's dessert. And then I compare different products, looking at the ratio of total carbs to fiber. And I look at protein, too. So, if I'm looking for a cereal bar, if I'm looking for some bread, some cookies, some crackers, any dry foods, this is a really, really good technique to have an ingredients list and carb to fiber ratio.

Now, the next thing I want to cover, which is so important, is the marketing tactics that different food companies and food packages will use to trick you into thinking their food is healthy. So, I'm going to go through a few main pitfalls here that I really want you to avoid.

The first culprit in this is glutenfree. If you see gluten-free on a packaging, it does not mean the food is good for you. It just means that it was made without wheat. But wheat is a source of carb like many other sources of carbs. It does not have that big of an impact on your health, especially if you're not gluten intolerant. And gluten is actually a protein. It keeps your glucose levels steady. So when a product is turned into a gluten-free product, often it's replaced by something else that is pure carbs, like some rice flour or something else like that. And in that case, the glucose spike could be even bigger than in the gluten containing product.

So gluten-free does not mean that the product doesn't contain any sugar. It can be the highest sugary, most bad for your food and still be gluten-free. Listen, soda is gluten-free. Gluten-free means nothing about the impact that that food is going to have on your health. It's so important. And just to show you, here's an example, a gluten-free chocolate cupcake. And as you can see from the glucose levels, it creates a big glucose spike. Gluten-free does not mean it's good for you. Do not be fooled into buying gluten-free stuff thinking that, "Oh, this is a healthy food. Oh, this gluten-free cupcake is super good for me." Uh-uh. No, no, no, no. Look at the ingredients. Look at the nutrition facts on the back. Gluten-free does not mean healthy.

Another big one, vegan. If something says it's vegan on the packaging, it does not mean it is good for you. There's nothing that annoys me more than seeing, for example, in a coffee shop where they say, "Oh, this cookie is vegan and gluten-free." And so people are buying that thinking that it's a healthy food all of a sudden. I'm like, "A cookie that's vegan and gluten-free can have really high amounts of sugar in it. It could have really high amounts of really unhealthy vegetable oils. There's no reason to believe that something that is vegan or gluten-free for that matter is good for you. Sugar is vegan. Soda is vegan. You can make vegan ice cream that's really, really high in sugars. There's so many unhealthy things today that are vegan. So again, if you see vegan on the packaging, just ignore it. It doesn't matter. Unless you're vegan, I mean, then it matters. But if you're not vegan, the fact that it says vegan should have zero zero implication and should trick you zero times. Never. Always look at the back of the ingredients list and at the nutrition label."

Another one also, and this is more controversial. So, if something says organic, yes, it's better for you in the sense that it's not going to be filled with pesticides, and yes, potentially it's better for the environment, too. But it's not because it's organic that it's all of a sudden a healthy food. A breakfast cereal that's super high in sugar could be organic and still create a massive glucose spike in your body and set your day up for a massive glucose roller coaster and having a really bad time. So, it's not because it's organic that it's good for you.

And the list goes on and on and on. The message here is simple. Whatever it says on the front of the package in the little, you know, the little bubbles that kind of pop out with a little cool design that says like gluten-free, vegan, organic, blah blah blah, ignore. Look at the back. I want you to be informed and to know exactly where the truth lies. Because you have to remember, food products are products that are heavily marketed and the companies want you to buy them. And it's fine if you want to buy them, and it's fine if you want to buy stuff that has a lot of sugar in them. But I want you to be aware of what you're buying. I don't want you to be tricked.

Listen, I buy ice cream all the time. I love sugary stuff. I'm not saying don't buy the sugar. I'm saying buy it with full awareness. Be aware of what you're doing. And that awareness comes from understanding that the front of the package means nothing. And you have to turn it over to get to the truth.

So, I hope that was helpful. That was kind of like a download of my brain and what I do when I go to the supermarket. And again, if you want all this in a page that you can bring to you when you're grocery shopping, download the PDF in the description of this episode. It has all my tricks in a single page so you can be informed and you can have these superpowers when you're buying your food.

Thank you for watching. I'll see you next time.

We’re bombarded by misleading marketing every time we step into a grocery store. “Gluten-free”, “vegan”, “organic”... these sound healthy, right? But most of the time, they’re just marketing fluff and actually bad for your health. Let me show you where the real truth lives: on the back of the package

Being able to decode food labels will change how you shop forever, so here are my top tips for you.

Tip #1: Start with the ingredients list

Always flip the package over and start with the ingredients list. It’s written in descending order by weight, so the first few ingredients are what the product is mostly made of.

💡 My rule: If sugar is in the top 5 ingredients, that product is dessert, no matter what the front says (protein bar, granola, cereal, whatever). You can still eat it, but just know what it is.

Sugar hides behind many names. Here are just a few:

  • Agave nectar
  • Fruit juice concentrate
  • Cane sugar
  • Maltodextrin
  • Rice syrup
  • Honey
  • Glucose
  • Sucrose

And there are so many more. I made a free PDF guide of the full list of hidden sugar names to help you navigate through the noise.

The ingredients list in Innocent Smoothies.

Sugar under 4 different names (and a dash of lemon juice) I know they look cute, but remember, fruit juice is just sugar.

And here’s another important note:

The longer the ingredient list, the more likely it is that the product is ultra-processed, meaning it's been heavily altered from its original form using additives, extracts, flavorings, and industrial processing techniques.

📌 If you see a list with 10, 15, or 20+ ingredients, many of which you can’t pronounce or don’t recognize as real food, that’s a red flag.

Ultra-processed foods tend to spike glucose more, increase cravings, and leave you feeling less satisfied.

Tip #2: Skip the calories, focus on the ratio

First things first, you can skip right past the Calories line. Yes, it’s the biggest line, because that’s what manufacturers want you to focus on the most. But as I’ve explained, the molecules matter more than the calories. And in the Nutrition Facts, the molecules inside of a food are spelled out for all to see, if you know where to look. 

Look at these lines:

  • Total carbohydrates
  • Dietary fiber

When assessing dry foods (like cookies, pasta, bread, cereal, cereal bars, crackers, chips, etc.), the grams next to Total Carbohydrate and Total Sugars represent the molecules that cause a glucose spike: starches and sugars.

The more grams of these, the more the food will lead to a glucose spike and set off the chain reaction that keeps us craving sweet things.

Importantly, this section also contains the Dietary Fiber line. Fiber is the only carbohydrate that our bodies don’t break down: the more fiber in the food, the flatter the curve. 

My top tip: look at the ratio of Total Carbohydrates to Dietary Fiber. For every 5g of carbs, aim for at least 1g of fiber.

You can calculate this by: finding the number next to Total Carbohydrates and dividing it by 5. Try to find a food that has that amount of Dietary Fiber (or as close to it as possible).

Why 5? It’s an arbitrary cut-off, but I use it because that’s close to the ratio we find in fruit like berries. The science is not exact, but I’ve found that the closer to this ratio, the flatter the glucose curve. Anything more, and you can be fairly certain this food will cause a spike.

Here are two cereal labels: Fiber One on the left, Special K on the right. The one on the left has a better fiber to carb ratio (14 grams of fiber per 25 grams of total carbs vs. 2 grams per 25 grams of total carbs). The one on the left is a better choice.

Tip #3: Check the protein

Protein keeps you full, builds your muscles, and flattens your glucose curve. So check that protein line too. The higher, the better.

Once you’ve checked the ingredients and looked at the carb-to-fiber ratio, the next thing I want you to look at is the protein content. This is one of the most important (and underrated) parts of the nutrition label.

Protein is essential. It’s not just about building muscles or bulking up. Your body literally needs protein to stay alive. Every cell in your body requires amino acids (the building blocks of protein) to function: your skin, your brain, your immune system, your hormones, your enzymes, they all depend on protein.

Protein also helps you feel full and satisfied, so you're less likely to overeat or snack on sugary things later. It supports healthy metabolism and plays a huge role in regulating your appetite.

(Check out my episode on protein for more details.)

Here’s the simple rule: The higher the protein, the better. Especially when you’re choosing snacks, cereals, bars, or breads.

Let’s say you're comparing two granola bars:

  • One has 2 grams of protein
  • The other has 9 grams of protein

Assuming the rest of the label is similar (carbs and fiber, etc.), go for the one with more protein.

And no, don’t let anyone scare you about “too much protein.” Most people aren’t getting enough. In fact, getting a good amount of protein in each meal is one of the best long-term strategies for managing glucose, insulin, hunger, and even healthy aging (see the science here).

Tip #4: Don’t fall for front-label marketing

Let’s talk about the front of the food package, the part that’s designed to catch your eye and trick your brain.

Food companies put all sorts of labels and claims there to make their product look healthy… even when it’s not. And the truth is, those catchy bubbles are often just marketing tactics. They tell you nothing about the product’s actual impact on your health. Here's what you really need to know:

"Gluten-free"

One of the most common traps is the “gluten-free” label. If you’re not gluten intolerant, this label should mean nothing to you, and definitely shouldn’t be read as “healthy.”

Gluten is a protein, not a carb, and in many cases, it actually helps stabilize your glucose levels. So when a company removes gluten, they often replace it with something worse, like white rice flour, tapioca starch, or cornmeal, all of which are very high in carbs and cause even bigger glucose spikes.

Even soda is gluten-free… that should tell you everything you need to know.

So yes, that gluten-free chocolate cupcake might sound better than a regular one. But if you look at your glucose monitor after eating it? Massive spike.

"Vegan"

Another sneaky one is “vegan.” If you're vegan for ethical or environmental reasons, of course that label matters to you. But if you’re just trying to eat healthy, don’t assume “vegan” means better for your body.

There are vegan cookies, vegan brownies, vegan ice creams, all loaded with sugar, refined grains, and inflammatory vegetable oils. These products can cause huge glucose spikes, even if there's no animal product in sight.

So when you see “vegan & gluten-free” on a cookie at a coffee shop or supermarket, don’t think, “Oh good, healthy treat!” Think: “Better check the ingredients list.”

"Organic"

Yes, organic products use fewer pesticides and are better for you (and the environment) than their non-organic counterparts. 

But organic sugar is still sugar. You can have an organic granola bar or organic cereal that’s packed with sugar, stripped of fiber, and sends your glucose levels sky high. “Organic” tells you something about how the ingredients were grown, not what they do in your body.

So again, don’t stop at the front. Flip it over.

The Bottom Line

The front of the packaging is just advertising. It’s where food companies put the health halo to make you feel good about your choice.

But here’s the truth: It doesn’t matter what the front says. What matters is on the back: the ingredients list and the nutrition facts.

It’s not about avoiding sugar completely. It’s about being informed. I still eat ice cream! I still enjoy treats. But I know what I’m getting. I’m choosing them with awareness, not because I got fooled by a label.

💡 So next time you shop, be the detective. Flip the box. Read the facts. Your blood sugar (and energy levels) will thank you.

FAQ'S

Should I never buy anything that has sugar in the top 3 ingredients? 

No, that would be draconian! The most important thing is to be aware of what spikes you and what doesn’t. When I buy ice cream, I’m buying a food that has a ton of sugar in it. It will definitely cause a glucose spike. I know that. It’s a conscious decision. I eat it on occasion, rather than every day. For things like yogurts, cereal and bread, which I do eat every day, I buy the versions I know will keep my glucose levels flat.

Can I combine these foods with protein and fiber from a different source?

Yes, absolutely you can. You can always buy a food that could cause a spike, then, when you eat it, combine it with fiber, protein and fat. Like having oreos with greek yogurt and nuts. But you’ll make it easier on yourself if you start with ingredients that will help keep your glucose levels flat anyway.

Isn't “fruit juice” or “pressed fruit” healthy for us since it has vitamins?

It’s still sugar. Even if it comes from fruit, once it’s been pressed, juiced, or concentrated, all the fiber is gone and what’s left behaves just like table sugar in your body. So if you see “fruit juice concentrate,” “crushed grapes,” or “apple puree” in the first few ingredients, that’s dessert.

Why ignore calories? Isn’t that the most important number?

Calories only tell you how much energy a food has, not how it affects your body. A donut and an avocado can have the same calories but totally different impacts on your glucose, hunger, inflammation, and health. That’s why we skip the calorie number and look at the carbs, fiber, and protein instead.

How much protein should I look for?

In general: the more, the better. An ideal goal is around 1 gram per pound of bodyweight. Protein helps reduce glucose spikes, keeps you full, and gives your body essential amino acids. I made a free protein calculator for you to check your daily protein requirements.

I saw a “healthy” granola in the supermarket with organic oats and dried fruit — is that okay?

Check the ingredients list and nutrition facts. If sugar (or dried fruit, juice concentrate, etc.) is high up in the list (which it likely is), and if there’s little fiber or protein, it’s going to spike your glucose. Even if it’s organic, it could still be a glucose rollercoaster in a bowl.
