How to Improve Gut Health

Hippocrates, the father or modern medicine said, “All disease begins in the gut.”

And while this may not be 100% true for every disease in every person, more and more research shows that our gut (digestive system) has a bigger role in many diseases than we used to think.

We’re not just talking about heartburn, constipation, diarrhea, IBS, IBD, etc. We’re talking about all kinds of issues like allergies, pain, mood disorders, and nutrient deficiencies.

There are many reasons for this. Our gut is the portal to the outside world. It’s here where we take in disease-causing bacteria, viruses, and parasites. We also take in nutrients (and toxins) through our gut. The nutrients we ingest and absorb are the building blocks of every single part of our body.

We’re just learning the connections between our gut and other areas of our body, like our brain (have you heard of “the gut-brain axis”). Not just our gut per se; but, its friendly resident microbes too. These guys also have newly discovered roles in our gut health and overall health. Cue the current buzzword microbiome.

So, let’s talk about the roles that our gut and our gut microbes (both healthy and unhealthy bacteria) play in our overall health. Then I’ll offer some tips to improve your gut health naturally.

Our gut’s role in our overall health

Our gut’s main role is to act as a barrier. The intestinal lining is intended to let things in that should get in, and to keep things out that should stay out. Think of “absorption” of nutrients as things we want to let in; and “elimination” of waste as things we want to pass right through and out.

This seemingly simple role is actually very complex! And it can break down in so many places.

For one thing, our guts can “leak.” Yes, like a long tube with holes in it, it can allow things to get into our bloodstream/bodies that can wreak havoc on our bodies (bacteria, undigested food, and toxins).

Anything you put into your mouth can be absorbed by your gut and get into your bloodstream, even if it’s not supposed to. And when your gut wall gets irritated, it can “leak.” When this happens, you get inflammation, which is a starting point for many diseases that don’t seem linked to the gut but have a sneaky connection there.

Fact: About 70% of our immune system lives in and around our gut.

A healthy gut is not a leaky gut. It maintains its barrier and shuttles things through to be eliminated. Maintaining a healthy gut barrier is the first pillar of gut health.

The second main part of your gut are the billions of friendly health-promoting microbes. Gut microbes are important and extremely useful. They help us digest and absorb nutrients, fight off disease-causing microbes, make some vitamins, and have all kinds of other health benefits, like mental health benefits, reducing inflammation, and stabilizing blood sugar.

So, keeping your gut microbes happy is vital to promoting gut health.

How to improve gut health

There are a lot of natural ways to improve gut health. It starts with eliminating the cause of irritation and inflammation. Basically, we need to stop giving our guts junk to deal with. You would be amazed at how much better your body (and gut) feels after eliminating added sugars, processed foods, and alcohol for a few weeks.

You may also want to eliminate other gut irritants. Dairy and grains contain common compounds known to irritate some people’s guts. Sometimes you only need to eliminate them for a few weeks to see if it makes a difference for your health.

Note: I’m not saying that you should remove dairy and grains completely from your diet. Every body is different. These are two main culprits to look to if you’re experiencing bloating, gas and other intestinal disruption.

By eating nutrient-dense foods, we allow ample macro- and micro-nutrients into our gut to maximize the chance for absorption. These nutrients help our bodies build and repair our gut, and every other body part as well. Some of the most nutrient-dense foods include dark leafy greens, colourful fruits and veggies, and fish.

Next, we need to focus on our microbes. By ingesting probiotic-rich foods and drinks, we can help to replenish our gut microbes. These are found in fermented foods like kombucha, kefir, miso, sauerkraut, and kimchi. Make these a part of your daily (if not weekly) diet.

Whole foods are full of gut-friendly fiber. Not eating enough fiber increases the risk of heart disease, cancer, diabetes, and obesity. Fiber plays lots of roles in our gut, including whisking away some of those pesky bad bacteria and toxins so they can be eliminated. Fiber also helps to feed our friendly resident microbes that help us absorb and digest our food better. What foods have a lot of fiber? Fruits, vegetables, nuts, seeds, and even cacao.

And don’t forget the uber-important lifestyle factors like getting enough sleep, stressing less, and getting the right amount (and intensity) of exercise for you. It’s easy to forget some of the simple, but key links there are between what we do with our bodies and how well they function.

Did you know there are certain yoga poses that target gut health? Twists, Downward Dog, Wind-relieving Pose and the restorative Legs Up The Wall (Google them) are a few you can start with.

Conclusion

The function of your gut is key to your overall health. There are two key factors for gut health: maintaining a good barrier and maintaining healthy gut microbes.

The main ways to improve both of these naturally is by eating nutrient-dense whole foods. Foods filled with nutrition, probiotics, and fiber. And eliminating common gut irritants like added sugar, processed foods, and alcohol.

Recipe: Probiotic-rich Fermented Carrots

Serves 12

1 L warm water
4 tsp salt
4 carrots, medium, peeled, sliced

1 clove garlic, smashed (optional)

Instructions

Make a brine by dissolving the salt in water.

Place carrots into a clean canning jar, packing them in tight. Make sure to leave about 1 inch of head space at the top.

Fill the jar with brine, making sure to cover the carrots completely. Weigh the carrots down to make sure they don’t float (you can use a “fermenting weight”).

Close the jar and let it sit at room temperature for 1-4 days. The longer it sits, the more the flavor will develop. Feel free to open and taste.

Serve & enjoy!

Tip: Use this as a side dish, or even a snack.

How to Read the New Nutrition Facts Tables

The Nutrition Facts table is on the side of most packaged foods. It’s often found close to the ingredient listing.

The purpose of it is to help consumers make better nutrition decisions. When people can see the number of calories, carbs, sodium, etc. in food, they should be able to eat better, right?

Whether you like the Nutrition Facts table or not, let’s make sure you get the most out of it, since it’s here to stay!

Here’s my four-step crash course on reading the Nutrition Facts table.

Step 1: Serving Size

The absolute most important part of the Nutrition Facts table is to note the serving size. Manufacturers often strategically choose the serving size to make the rest of the table look good. Small serving = small calories/fat/carbs. So, it’s tricky.

All the information in the table rests on the amount chosen as the serving size. And, since every manufacturer chooses their own, it’s often difficult to compare two products.

In Canada, in the next few years (between 2017-2022), serving sizes will be more consistent between similar foods. This will make it easier to compare foods. The new labels will also have more realistic serving sizes to reflect the amount that people eat in one sitting, and not be artificially small.

Let’s use an example – plain, unsalted walnuts from Costco.

As you can see, right under the Nutrition Facts header is the serving size. That is a ¼ cup or 30 g. This means that all the numbers underneath it are based on this amount.

Try this out: use a measuring cup to see exactly how much of a certain food equals one serving. You may be surprised at how small it is. A ¼ cup of walnuts, is just a few pieces.

Keep in mind, that sometimes it’s ok to eat more than one serving at a time. This is when it’s important for you to know the basics on meal planning and food combining (which I teach in the Eats & Asana course so you can judge how much is right for you at one time.

Step 2: % Daily Value

The % Daily Value (%DV) is based on the recommended daily amount of each nutrient the average adult needs. Ideally, you will get 100% DV for each nutrient every day. This is added up based on all the foods and drinks you have throughout the day.

NOTE: Since children are smaller and have different nutritional needs, if a type of food is intended solely for children under the age of 4, then those foods use a child’s average nutrition needs for the %DV.

The %DV is a guideline, not a rigid rule.

You don’t need to add up your %DV for everything you eat all day. Instead, think of anything 5% or less to be a little; and, anything 15% or more to be a lot.

NOTE: Not every nutrient has a %DV. You can see it’s missing for things like cholesterol, sugar, and protein. This is because there isn’t an agreed “official” %DV for that nutrient. The good news is that the new Nutrition Facts tables will include a %DV for sugar. Keep your eyes out for that.

Step 3: Middle of the table (e.g. Calories, fat, cholesterol, sodium, potassium, carbohydrates, and protein)

Calories are pretty straight forward. Here, a ¼ cup (30 g) of walnuts has 200 calories.

Fat is bolded for a reason. That 19 g of fat (29% DV) is total fat. That includes the non-bolded items underneath it.

Here, 19 g of total fat includes 1.5 g saturated fat, (19 g – 1.5 g = 17.5 g) unsaturated fat, and 0 g trans fat. You’ll notice, unsaturated fats including mono- and poly-unsaturated are not on the label, so this quick subtraction accounts for that amount.

Cholesterol, sodium, and potassium are all measured in mg. Ideally, aim for around 100% of potassium and sodium each day. It’s easy to overdo sodium, especially if you grab pre-made, restaurant foods, or snacks.

Keep an eye on this number if sodium can be a problem for you (e.g. if your doctor mentioned it, if you have high blood pressure or kidney problems, etc.).

Carbohydrate, like fat, is bolded because it is total carbohydrates. It includes the non-bolded items underneath it like fiber, sugar, and starch (not shown).

Here, 30 g of walnuts contain 3 g of carbohydrates; that 3 g are all fiber. There is no sugar or starch. And as you can see, 3 g of fiber is 12% of your daily value for fiber.

Proteins, like calories, are pretty straight forward as well. Here, a ¼ cup (30 g) of walnuts contains 5 g of protein.

Step 4: Bottom of the table (e.g. vitamins & minerals)

The vitamins and minerals listed at the bottom of the table are also straightforward. The new labels will list potassium, calcium, and iron. Yes, potassium will drop from the middle of the table to the bottom, and both vitamins A & C will become optional.

Manufacturers can add other vitamins and minerals to the bottom of their Nutrition Facts table (though this is optional). And you’ll notice that some foods contain a lot more vitamins and minerals than others do.

Conclusion

I hope this crash course in the Nutrition Facts table was helpful. While you can take it or leave it when it comes to making food decisions, it’s here to stay. And it will change slightly over the next few years.

Do you have questions about it? Have you seen the new labels with a %DV for sugar? If so, leave me a comment below.

Common Weight Loss Myths Busted

Weight loss advice is so common (and contentious) now. There are competing opinions everywhere. Anyone else tired of this?

In my opinion, too much “health information” is focused on weight loss. I’d like to start out by saying, not all of us need to lose weight. Let’s be accurate about what the goal is really—do you need to change your body composition. build muscle and increase your strength? Most often this is the issue when clients come to me saying they want to “lose weight.”

When it comes to weight loss, for those of us who actually need to lose excess weight, let’s forget about focusing on “who’s right” and let’s focus on “what’s right.” Because what gets results is what I’m focusing on in this post.

I respect you too much to make empty promises and try to convince you of something that doesn’t work.

There are too many weight loss myths out there. I’m going to tackle the top ones I come across in my practice.

Myth #1: Calories cause weight gain, and fewer calories are the path to weight loss

Calories are important for weight loss. If you eat and absorb a ton more than you use, then your body’s wisdom will store some for later. Calories matter.

But, they are not the “be-all and end-all” of weight loss; they’re important, but they’re the symptom, not the cause. Let’s think about the reasons people eat more calories. Let’s focus on the causes.

People eat too many calories, not because they’re hungry, but because they feel sad, lonely, or bored. Or maybe because they’re tired or stressed. Or maybe even because they’re happy and celebrating. We are nourished by more than just what’s on our plates. And all these feelings interact with our gastrointestinal, nervous and hormonal systems; which influence our calorie intake.

Myth #2: “Eat less move more” is good advice

Well, then we’re all in tip-top shape, right? Because people have been doling out this advice (myth) for years.

The premise of this is based on the above myth that calories in minus calories out equals your weight. So, eat fewer calories, and burn off more calories (because human physiology is a simple math equation, right?).

Even if people can happily and sustainably follow this advice (which they can’t!); it completely negates other factors that contribute to weight problems. Things like the causes of overeating we mentioned above. Not to mention our genetics, health conditions we’re dealing with or our exposure to compounds that are “obesogenic.”

Myth #3: A calorie is a calorie

Can we please put this one to bed already?

Science has confirmed several caloric components of food differ from others. For example, the “thermic effect of food” (TEF) is that some nutrients require calories to be metabolized. They can slightly increase your metabolism, just by eating them.

For example, when you metabolize protein you burn more calories than when you metabolize carbohydrates. Proteins and carbohydrates both have 4 calories/gram; but, the TEF of protein = 15–30%; and the TEF for carbohydrates = 5–10%.

Here’s another example of a calorie not being a calorie. Different fats are metabolized differently. Medium chain triglycerides (fats) (MCTs) have the same 9 calories/gram that other fats do; but, they’re metabolized by the liver before getting into the bloodstream and therefore aren’t utilized or stored the same way as other fats. Psst…coconut oil is a good source of medium chain triglycerides.

Shout it out! #acalorieisnotacalorie

Myth #4: Buying a supplement/tea/food/magic potion will make you lose weight

There is no magic pill for weight loss. No supplement, tea, food, or other potion will do the trick.

There are products that make these claims, and they’re full of garbage (or shall I say “marketing gold?”). The only thing you will lose is your money (and possibly your hope). So, please don’t believe this myth. There is a reason most people who lose weight can’t keep it off. The real magic is in adopting a sustainable holistic and healthy approach to living your life. What you need is a long-term lifestyle makeover, not a product.

Myth #5: Weight loss is all about your body

Here’s one that we might think but rarely say out loud. Have you noticed that weight loss solutions are all about your body? They never consider that human psychology, our thoughts and emotions (which are what we base our decisions on) have something to do with the weight loss puzzle.

In fact, our thoughts and emotions are the missing piece. If you start your weight-loss journey from a place of self-sabotage, you’re already doomed for failure. Your body (and mind) responds best to loving and positive input. This is one reason why having a nutritionist or personal coach increases your chances of success on a weight loss journey.

Conclusion

Weight loss is a challenge! There are too many people out there trying to make it sound like they have the simple solution, when really it’s about consistency of your healthy habits.

Don’t fall for the myths that say:

  • Calories cause weight gain, and fewer calories are the path to weight loss.
  • “Eat less move more” is good
  • A calorie is a calorie.
  • Buy this supplement/tea/food/magic potion to lose weight.
  • Weight loss is all about your body (and not your mind/emotions).

Why Your Waist Circumference Matters 100x More Than What You Weigh

Are you in a love-hate relationship with your scale? You compulsively check the number, yet you don’t often like what you see.

You may have this weird kind of relationship with your “weight”.

First things first, your weight doesn’t define you (obviously).

Yet what you weigh can matter…but only to a certain extent.

Let’s look at your waist circumference for a minute instead (well…you look at yours and I’ll look at mine).

Waist Circumference (AKA “Belly Fat”):

Do you remember the fruity body shape descriptions being like an “apple” or a “pear”?  The apple is more thick and round around the middle, and the pear is more narrow in the waist and rounder around the hips/thighs.

THAT is what we’re talking about here.

Do you know which shape is associated with a higher risk of sleep apnea, blood sugar issues (e.g. insulin resistance and diabetes) and heart issues (high blood pressure, blood fat, and arterial diseases)?

Yup – the apple!

And it’s not because of the subcutaneous (under the skin) fat that you may refer to as a “muffin top”.  The health risk is actually due to the fat inside the abdomen covering the liver, intestines and other organs there.

This internal fat is called “visceral fat” and that’s where a lot of the problem actually is.  It’s this “un-pinchable” fat.

The reason the visceral fat can be a health issue is because it releases fatty acids, inflammatory compounds, and hormones that can negatively affect your blood fats, blood sugars, and blood pressure.

That’s right – visceral fat is hormonally and metabolically active. That means that it produces hormones (more than your body needs) and requires nutrients for up-keep, so your body will crave more nutrients just to keep this visceral fat thriving!

And the apple-shaped people tend to have a lot more of this hidden visceral fat than the pear-shaped people do.

So as you can see, where your fat is stored is more important that how much you weigh.

Am I an apple or a pear?

It’s pretty simple to find out if you’re in the higher risk category or not. The easiest way is to just measure your waist circumference with a measuring tape.  You can do it right now.

Note: measure your waist circumference at the level of your belly button.

Women, if your waist is 35” or more you could be considered to have “abdominal obesity” and be in the higher risk category.  Pregnant ladies are exempt, of course.

For men the number is 40”.

Of course this isn’t a diagnostic tool.  There are a lot of risk factors for chronic diseases.  Waist circumference is just one of them.

If you have concerns definitely see your doctor.

Tips for helping reduce some belly fat:

  • Eat more fiber. Fiber can help reduce belly fat in a few ways.  First of all it helps you feel full and also helps to reduce the amount of calories you absorb from your food.  Some examples of high-fiber foods are brussel sprouts, flax and chia seeds, avocado, and blackberries.
  • Add more protein to your day. Protein reduces your appetite and makes you feel fuller longer.  It also has a high TEF (thermic effect of food) compared with fats and carbs and ensures you have enough of the amino acid building blocks for your muscles.
  • Nix added sugars. This means ditch the processed sweetened foods especially those sweet drinks (think: flavoured cpapucchinos and lattes, even 100% pure juice).
  • Move more. Get some aerobic exercise.  Lift some weights.  Walk and take the stairs.  It all adds up.
  • Stress less. Seriously!  Elevated levels in the stress hormone cortisol have been shown to increase appetite and drive abdominal fat.
  • Get more sleep. Try making this a priority and seeing how much better you feel (and look).

Recipe (High fiber side dish): Garlic Lemon Roasted Brussels Sprouts

Serves 4

1 lb Brussels sprouts (washed, ends removed, halved)
2-3 cloves of garlic (minced)
2 tablespoons melted coconut oil or ghee
2 teaspoons fresh lemon juice
dash salt and pepper

Preheat oven to 400F.

In a bowl toss sprouts with garlic, oil, and lemon juice.  Spread on a baking tray and season with salt and pepper.

Bake for about 15 minutes.  Stir again to rotate.

Bake for another 10 minutes.

Serve and Enjoy!

Tip:  Brussel sprouts contain the fat-soluble bone-loving vitamin K.  You may want to eat them more often as a snack or a side dish.

Five Cholesterol Myths and What to Eat Instead

You knew there was a bit of an over-emphasis (borderlining obsession) about cholesterol, right?

Before we jump into some myths let’s make sure we’re on the same page when it comes to what exactly cholesterol is.

Myth #1: “Cholesterol” is cholesterol

While cholesterol is an actual molecule what it is bound to while it’s floating through your blood is what’s more important than just how much of it there is overall.  In fact depending on what it’s combined with it can have opposite effects on your arteries and heart.  Yes, opposite!

So cholesterol is just one component of a compound that floats around your blood.  These compounds contain cholesterol as well as fats and special proteins called “lipoproteins”.

They’re grouped into two main categories:

  • HDL: High Density Lipoprotein (AKA “good” cholesterol) that “cleans up” some of those infamous “arterial plaques” and transports cholesterol back to the liver.
  • LDL: Low Density Lipoprotein (AKA “bad” cholesterol) that transports cholesterol from the liver (and is the kind found to accumulate in arteries and become easily oxidized hence their “badness”).

Note: a quick tip for keeping these two types straight, think “H” for healthy, which signifies the “good” cholesterol.

And yes, it’s even more complicated than this.  Each of these categories is further broken down into subcategories which can also be measured in a blood test.

So “cholesterol” isn’t simply cholesterol because it can form different compounds which have very different effects on your body. The role of cholesterol depends on which other molecules it’s bound to in your blood and what it is actually doing there.

Myth #2: Cholesterol is bad

Cholesterol is absolutely necessary for your body to produce critical things like vitamin D when your skin is exposed to the sun, your sex hormones (e.g. estrogen and testosterone), as well as bile to help you absorb dietary fats.  Not to mention that it’s incorporated into the membranes of your cells.

Talk about an important molecule!

The overall amount of cholesterol in your blood (AKA “total cholesterol”) isn’t nearly as important as how much of each kind you have in your blood.

While way too much LDL cholesterol as compared with HDL (the LDL:HDL ratio) may be associated with an increased risk of heart disease it is absolutely not the only thing to consider for heart health.

Myth #3: Eating cholesterol increases your bad cholesterol

Most of the cholesterol in your blood is made by your liver.  It’s actually not from the cholesterol you eat.  Why do you think cholesterol medications block an enzyme in your liver (HMG Co-A reductase, to be exact)?  ‘Cause that’s where it’s made!

What you eat still can affect how much cholesterol your liver produces.  After a cholesterol-rich meal your liver doesn’t need to make as much.

I’ve had many clients ask me over the years whether they should stop eating eggs because of the cholesterol in them. My answer is almost always NO! Unless there are other health factors present (like allergies), eggs are a healthy food and contain good quality fats and protein. They’re a great part of a healthy diet.

Myth #4: Your cholesterol should be as low as possible

As with almost everything in health and wellness there’s a balance that needs to be maintained.  There are very few extremes that are going to serve you well.

People with too-low levels of cholesterol have increased risk of death from other non-heart-related issues like certain types of cancers, as well as suicide.

Myth #5: Drugs are the only way to get a good cholesterol balance

Don’t start or stop any medications without talking with your doctor.

And while drugs can certainly lower the “bad” LDL cholesterol they don’t seem to be able to raise the “good” HDL cholesterol all that well.

Guess what does?

Nutrition and exercise, baby!

One of the most impactful ways to lower your cholesterol with diet is to eat lots of fruits and veggies.  I mean lots, say up to 10 servings a day.  Every day.

Don’t worry the recipe below should help you add at least another salad to your day.

You can (should?) also exercise, lose weight, stop smoking, and eat better quality fats.  That means fatty fish, avocados and olive oil.  Ditch those over-processed hydrogenated “trans” fats.

Summary:

The science of cholesterol and heart health is complicated and we’re learning more every day.  You may not need to be as afraid of it as you’ve been led to believe.  There is a lot you can do from a nutrition and lifestyle perspective to improve your cholesterol level.

Recipe (Dressing to go with your salad): Orange Hemp Seed Dressing

Makes about ¾ cup

½ cup hemp seeds
½ cup fresh-squeezed orange juice
2 Tbsp olive oil
1 clove of garlic, peeled
dash salt and/or pepper

Blend all ingredients together until creamy.

Serve on top of your favourite salad and Enjoy!

Tip: Store extra in airtight container in the fridge.  Will keep for about a week.
