Let’s finally put an end to the debate of raw vs. cooked.

Of course, in the grand scheme of a well-balanced, nutrient-dense, varied, whole foods diet, the cooked vs. raw debate isn’t that critical for most people.

Where this can become a consideration is for vitamin and mineral deficiencies (or “insufficiencies”). These may be due to digestion or absorption issues, or avoidance of certain foods (due to allergies, intolerances, or choice).

And I’ll tell you that the answer isn’t as simple as “raw is always better” or “cooked is always better.” As with most nutrition science, it depends on several factors. Some vitamins are destroyed in cooking, while others become easier to absorb (a.k.a. more “bioavailable”).

Here is the skinny on vitamins and minerals in raw foods versus cooked foods.

Foods to eat raw

As a general rule, water-soluble nutrients, like vitamin C and the B vitamins, found mostly in fruits and vegetables, are best eaten raw.

The reason why is two-fold.

First, when these nutrients are heated, they tend to degrade;  this is from any heat, be it steaming, boiling, roasting, or frying. Vitamin C and the B vitamins are a bit more “delicate” and susceptible to heat than many other nutrients.

Of course, the obvious way to combat these nutrient losses is to eat foods high vitamin C and B vitamins in their raw form (like in an awesome salad) or to cook them for as short a time as possible (like quickly steaming or blanching).

Fun fact: Raw spinach can contain three times the amount of vitamin C as cooked spinach.

The second reason why foods high in vitamin C and the B vitamins are best eaten raw is that they’re “water soluble.”  So, guess where the vitamins go when they’re cooked in water?  Yes, they’re dissolved right into the water;  this is particularly true for fruits and veggies that are boiled and poached but even for foods that steamed as well.

Of course, if you’re a savvy health nut, you’ll probably keep that liquid to use in your next soup or sauce to preserve those nutrients that are left after cooking. Just don’t overheat it or you may lose what you were aiming to keep.

But, how much loss are we talking about?  Well, of course, it ranges but can go from as low as 15%, up to over 50%.

In short, the water-soluble vitamins like vitamin C and the B vitamins degrade with heat and some of what’s left over after they’re heated dissolves into the cooking water. So be sure to cook your fruits and veggies as little as possible, and keep that cooking water to use in your next recipe.

Soaking nuts and seeds

Regarding raw nuts and seeds, it may be beneficial to soak them. Soaking nuts and seeds (for several hours at room temperature) allows some of the minerals to become “unlocked” from their chemical structure, so they’re more absorbable.

Foods to eat cooked

Cooking certain orange and red “beta-carotene rich” veggies (e.g. tomatoes, carrots, & sweet potatoes) can help make this pre-vitamin A compound more absorbable.

Fun fact: One study found that absorption of beta-carotene was 6.5 times greater in stir-fried carrots than in raw carrots!

Of course, eating your fat-soluble vitamins with a bit of fat will help you to absorb more of them, so that’s one factor to consider.

One vegetable that’s best eaten both raw and cooked

Spinach!

And I’m not just saying this to get everyone to eat it any way possible (although, I would love for this to happen…unless you’re allergic, of course).

Spinach contains so many beneficial compounds that it’s great eaten both raw and cooked.

Eating raw spinach preserves the water-soluble vitamins C & the B vitamins.

Eating spinach cooked allows the pre-vitamin A, as well as some of the minerals like iron to be better absorbed. Not to mention how much spinach reduces in size when it’s cooked, so it’s easier to eat way more cooked spinach than raw spinach.

Conclusion:

The old nutrition philosophy of making sure you get a lot of nutrient-dense whole foods into your diet holds true. Feel free to mix up how you eat them, whether you prefer raw or cooked just make sure you eat them.

Recipe (cooked spinach): Sauteed Spinach

Serves 4

2 teaspoons olive oil

2 cloves garlic

1 bag baby spinach leaves

1 dash salt

1 dash black pepper

Fresh lemon

1. In a large cast iron pan heat olive oil. 

2. Add garlic and saute for 1 minute.

3. Add spinach, salt, pepper and toss with garlic and oil. 

4. Cover pan and cook on low for about 2 minutes. 

5. Saute cook spinach for another minute, stirring frequently, until all the spinach is wilted.

6. Squeeze fresh lemon juice on top.

Serve & enjoy!

Tip: Enjoying the cooked spinach with the vitamin C in the “raw” lemon juice helps your body absorb more of the iron.

The words “weight-loss” and “snacks” often appear in the same sentence.

But that might also bring thoughts of “tasteless”, “cardboard”, and “completely unsatisfying”.

Right?

Let me give you my best weight-loss friendly snacks that aren’t just nutritious but also delicious!

What’s my criteria you ask?

They have to be nutrient-dense whole foods where a little goes a long way; foods that contain protein and/or fibre.

1 – Nuts

It’s true – nuts contain calories and fat, but they are NOT fattening!

Well, I’m not talking about the “honey roasted” ones, of course. Those probably are fattening.

Studies show that people who eat nuts tend to be healthier and leaner.

By the way, nuts also contain protein and fiber, which means a small amount can go pretty far in terms of filling you up. Not to mention the vitamins and minerals you can get from nuts.

Did you know that almonds have been shown to help with weight loss? At least 10% of the fat in them is not absorbed by the body, and almonds can also help to boost your metabolism!

Tip: Put a handful of unsalted/unsweetened nuts into a small container and throw it in your purse or bag.

 

2 – Fresh Fruit

As with nuts, studies show that people who tend to eat more fruit, tend to be healthier. (I’m sure you’re not too surprised!)

Yes, fresh fruit contains sugar, but whole fruits (I’m not talking juice or sweetened dried fruit) also contain a fair bit of water and fiber; not to mention their nutritional value with vitamins, minerals, and antioxidants. And fresh fruit is low in calories.

Fiber is something that not only helps to fill you up (known as the “satiety factor”) but also helps to slow the release of the fruit sugar into your bloodstream and reduce the notorious “blood sugar spike.”

Win-win!

Try a variety of fruit (apples, pears, berries, etc.) and pair that with a handful of nuts.

Tip: Can’t do fresh? Try frozen. Plus, they’re already chopped for you.

 

3 – Chia seeds

This is one of my personal favourites…

Chia is not only high in fibre (I mean HIGH in fibre), but it also contains protein and omega-3 fatty acids (yes THOSE omega-3s!). As well as antioxidants, calcium, and magnesium.

Can you see how awesome these tiny guys are?

They also absorb a lot of liquid, so by soaking them for a few minutes, they make a thick pudding (that is delicious and fills you up).

Tip: Put two tablespoons in a bowl with ½ cup of nut milk and wait a few minutes. Add in some berries, chopped fruit or nuts, and/or cinnamon and enjoy!

 

4 – Boiled or poached eggs

Eggs are packed with nutrition and most of it is in the yolk.

They contain a lot of high-quality protein and a good amount of vitamins and minerals.

And recent research shows that the cholesterol in the yolks is NOT associated with high elevated cholesterol or heart disease risk.

Yup, you read that right!

Tip: Boil a bunch of eggs and keep them in your fridge for a super-quick (and nutritious) snack!

 

5 – Vegetables

I don’t need to tell you how great these are for you, but just maybe I need to sell you on the delicious “snackability” of these nutrition powerhouses.

Veggies contain fibre and water to help fill you up, and you don’t need me to tell you about their vitamins, minerals, and antioxidants, right?

You can easily open a bag of baby carrots and/or cherry tomatoes and give them a quick rinse (they’re already bite-sized).

Tip: Use a bit of dip. Have you put almond butter on celery? How about trying my new hummus recipe below?

 

Conclusion:

Go ahead and try one, or more, of these healthy snacks. Prepare them the night before if you need to. They will not be “tasteless,” like “cardboard,” or “completely unsatisfying.” Trust me.

 

Recipe (Vegetable Dip): Hummus

Makes about 2 cups

1 can chickpeas (garbanzo beans), drained & rinsed
⅓ cup tahini
1 garlic clove
2 tbsp sesame oil
2 tbsp lemon juice
1 dash salt
1 dash pepper

1. Put all ingredients into a food processor and blend until smooth. You may need to thin it out with a bit of water, so add it 1 or 2 tablespoons at a time and blend.

Serve & enjoy!

Tip: Don’t like sesame? Use an avocado in place of the tahini, and olive oil in place of the sesame oil.

Not everyone should be taking digestive enzyme supplements, and not all of them are created equal.

As a practitioner, I find that many people with digestive issues want to jump straight into using a supplement. And many times I would rather try other strategies first. Not to mention, that some supplements can be harmful if used inappropriately.

So, let’s dive into a few of the common digestive enzymes, what they do, and who should NOT take them.

What are digestive enzymes?

Technically, “enzymes” are compounds that help critical biochemical reactions to happen in your body. These reactions can be anything, from making neurotransmitters like serotonin, to burning food for energy, to breaking down the food we eat into smaller pieces that our guts can absorb.

Oh, and they all end with “ase”.

As I just hinted, “digestive enzymes” are specifically those enzymes we use for digestion. They’re enzymes that our digestive system naturally makes and secretes when we eat.

Now, all of the “macronutrients” we eat (carbs, protein & fat) need to be broken down into their individual (smaller) parts so that we can properly absorb and digest them. They’re just too big otherwise, and if we don’t absorb them properly, we can get symptoms of fatigue, malnutrition, digestive distress, or a host of other symptoms.

It is this individual (smaller) parts that our body amazingly rearranges and uses to create other larger molecules that our body needs.

The most common digestive enzymes you’ll see on product labels are:

• Amylase – Helps to break down starch into its sugars.
• alpha-Galactosidase – Helps to break down specific “fermentable carbohydrates” into its sugars.
• Lactase – Helps to break down lactose into its sugars.
• Protease – Helps to break down protein into its amino acids.
• Bromelain and/or Papain – Help to break down protein into its amino acids.
• Lipase – Helps to break down fats into its lipids.

Who should consider taking digestive enzymes?

I would always recommend that you see a qualified health care practitioner for an expert opinion on whether your issues can be related to digestion, and which, if any, supplements can help you.

In general, the most common digestive symptoms that enzymes *may* help with are bloating, cramping, and/or diarrhea. Particularly if it happens after eating certain foods (think lactose-intolerance symptoms after eating dairy).

One reason for these symptoms can be those food particles are not broken down properly, and the larger pieces travel further down the digestive tract to the microbiota where those little critters start breaking them down themselves. And this is definitely troublesome for certain people.

Don’t get me wrong, a healthy gut microbiota is absolutely essential for good health. And more and more research is showing just how it can affect not only our digestion, but also our immune system, and even our mood.

What do I need to know? – Medical conditions

Of course, you should read the label of any products you take, and take them as directed, especially if they’re not specifically recommended for you by your health care practitioner who knows your history.

Here are two critical things to be aware of:

1 – Digestive enzymes that break down carbohydrates into sugars are not recommended for diabetics or pregnant/breastfeeding women.

This is because taking them breaks down more carbohydrates into sugars than your body normally would; so, anyone at risk of blood sugar issues should take caution.

2 – When it comes to enzymes that break down proteins into amino acids, there are a few people who should avoid them because of potential interactions. That is if you have an ulcer, or are taking blood-thinners or anti-inflammatories, or if you’re having surgery.

The reason is that the digestive enzymes that break down protein are thought to cause or worsen ulcers, as well as have the ability to “thin” the blood and prevent normal clotting.

What do I need to know? – Possible Side effects

Using digestive enzyme supplements for a prolonged period of time may well justify an appointment with a knowledgeable practitioner. There may be strategies other than daily supplementation that can serve you better.

If you find that your symptoms get worse, or even if they don’t get better, you should probably stop using them.
Allergies are always a possibility, so if you know or suspect you’re allergic, then you should avoid them.
And, as always, keep supplements away from children.

Before considering a digestive enzyme supplement

You shouldn’t just jump to supplementing with digestive enzymes without a proper diagnosis or trying a few strategies first.

My first recommendation for digestive distress would be to relax more, eat slower, and chew more thoroughly. This helps to break down food and can put less stress on your digestive tract.

The second step would be to try eliminating certain troublesome foods from your diet (dairy & gluten, for example) and see if that helps.

Conclusion:

While many supplements are safe products, they’re not all for everyone.

I recommend that you:

• Read your labels carefully (who should take them, how to take them, when to stop taking them).
• If you have a medical condition or are taking medications speak with your doctor or pharmacist.
• If you want expert advice on whether a specific supplement is for you, speak with a qualified healthcare practitioner.

Recipe (food containing bromelain & papain): Tropical (digestive) smoothie

Having a food intolerance is not fun. It can cause abdominal pain, discomfort, and nausea. It also causes embarrassing symptoms like flatulence and diarrhea. Other symptoms linked to food intolerances include muscle or joint pain, headaches, exhaustion, and even skin symptoms like rashes and eczema.

Dairy is just one of those foods that many people seem to be intolerant of. Let’s talk about the main components of milk that people react to lactose, casein, and whey.

Milk sugar (lactose) intolerance

It’s estimated that up to 75% of adults are lactose intolerant. Lactose is the carbohydrate “milk sugar” naturally found in most dairy products. Lactose intolerance is so common you can buy lactose-free milk at your regular grocery store. Lactose-free products are treated with the enzyme “lactase” that breaks the lactose down before you ingest it. It’s this lactase enzyme that is lacking in most people who are lactose intolerant.

The lactase enzyme is naturally released from your intestine as one of your digestive enzymes. It breaks down the lactose sugar in the gut. When someone doesn’t have enough lactase, the lactose doesn’t get broken down the way it should. Undigested lactose ends up being food for the resident gut microbes. As they ferment the lactose, they create gases that cause bloating, flatulence, pain, and sometimes diarrhea.

Lactose is in dairy but is in lower amounts in fermented dairy (e.g. cheese & yogurt) and butter. Steering clear of lactose isn’t that easy as it is added to other foods like baked goods, soups, and sauces. And if you’re taking any medications or supplements, check to see if it’s in there too, as lactose is a common ingredient in them.

If you have symptoms of lactose intolerance, keep an eye on food, medication, and supplement labels.

Milk protein (casein & whey) allergy

Milk is a known, and common, food allergen. In Canada, it is considered a “priority allergen” and must be declared on food labels.

So, what are the allergens in milk? You’ve heard of “curds and whey?” Well, these are the two main proteins in milk. The solid bits are the curds (made of casein), and the liquid is the dissolved whey.

Unlike lactose intolerance, casein and whey can cause an actual immune response. It’s an allergy. And this immune response can cause inflammation. In fact, we don’t know how many people have these milk allergies, but most estimates put it far below that of lactose intolerance.

Like lactose, these allergenic milk proteins can be found in other products too. They’re not just in dairy but are often in protein powders as well (Have you heard of “whey” protein powders?).

Some of the symptoms of milk protein allergy differ from that of lactose intolerance; things like nasal congestion and mucus (phlegm) are more common here. And casein seems to be linked with belly fat.

Interestingly, people who have gluten intolerance are often allergic to milk proteins like whey and casein as well. These can go hand-in-hand.

Like lactose intolerance, if you’re allergic to casein and whey keep an eye on labels so you can avoid these.

Conclusion

If you get gassy, bloated, or diarrhea after eating dairy, you may have a lactose intolerance. If you often get a stuffy nose and mucus, then you may be allergic to casein and/or whey.

While dairy may be an entire food group, it is not an essential nutrient. All the nutrients in dairy are available in other foods. If you experience these symptoms, you can try removing dairy from your diet. You may find improved digestion and fewer gut issues. Or you may find improved nasal congestion, or even less belly fat.

If you decide to (or have already) removed dairy from your diet, let me know your experience in the comments below.

A food preservative is a substance added to foods to make them last longer; to “preserve” them. Preservatives are added to foods that go bad quickly and have found themselves in all kinds of products in our grocery stores.

Preservatives work to preserve food in a few different ways. Some prevent the growth of bacteria and mold. Others prevent delicate fats from going rancid.

There are so many preservatives out there. While preservatives added to foods should be “approved”, this doesn’t mean they’re guaranteed to be safe for everyone always. And it doesn’t mean that the food is healthy.

Foods with preservatives are more-processed, less-nutritious foods to begin with – not exactly health foods. So, even if you don’t mind preservatives, you probably should cut down on these kinds of foods, anyway.

So, let’s learn more about a few common food preservatives.

Salt

That’s right – salt.

FUN FACT: The term “salary” is from the Latin word for salt. It’s thought that it came from the ancient Romans who would pay employees, allowing them to buy salt. Either that, or it was for their work conquering and/or guarding salt mines/roads. Either way, salt was sought because of its ability to preserve food before the advent of refrigeration.

In today’s day and age, with fridges and freezers in every home and grocery store, and refrigerated trucks, salt is not needed for food preservation as much. But our taste buds still seem to crave it on an epic scale. The average American eats over 3,400 mg of sodium per day, well over the recommended 2,300 mg/day. Much of that is because it’s found in processed foods.

According to Harvard Health:

“… reducing dietary salt (table salt that is only sodium, chloride and iodine) will lower blood pressure, reduce the risk of heart attack and stroke, and save lives.”

So, salt is one of those all-too-common food preservatives that most of us will do better with less of.

Nitrites (nitrates and nitrosamines)

Nitrites are preservatives added to processed meats. They’re not bad in and of themselves, but they do turn into harmful chemicals called nitrosamines. Nitrosamines are carcinogens found in cigarette smoke. Nitrites form nitrosamines when they’re cooked at high heat, and sometimes even when exposed to the high acid environment of the stomach.

Nitrites are added to meats to keep the pink-red colour and prevent “browning.” Mostly in bacon, ham, sausages and lunch meats. Since nitrites can change into nitrosamines, nitrites are one-step away from being the “bad guys.”

Another interesting thing is that processed meats have been linked with colon cancer. Because of the nitrites? Perhaps, but either way, nitrosamines are a confirmed health-buster.

Since nitrosamines (from nitrites) are the bad guys and are formed by cooking nitrites at high heat, what are nitrates?

Nitrates are naturally found in many healthy foods like vegetables. They’re especially high in beets. Sometimes our enzymes or gut bacteria change these healthy nitrates into nitrites. However, they rarely form nitrosamines because they’re two-steps away from becoming these “bad guys.”

BHA & BHT

Have you seen on packages “BHA/BHT has been added to the package to help maintain freshness?” Perhaps on cereal packages or in gum? Guess how these compounds maintain freshness? Because they’re preservatives.

BHA (butylated hydroxyanisole) and BHT (butylated hydroxytoluene) are antioxidants added to many processed foods. The main way BHA and BHT work is by preventing fats from going rancid.Are they safe? Well, they’re approved for use as a preservative at small doses. However, some studies show they can cause cancer in animals at high doses. Again, they’re added to processed pre-packaged foods, so it’s wise to avoid them nonetheless.

Conclusion

There are a lot of preservatives in our food supply. These compounds work by preventing the growth of bacteria and mold, or by preventing fats from going rancid. And they’re mostly found in processed foods. If you want to avoid them. Eat fresh foods.

Recipe (preservative-free): Kale Chips

Serves 4

1 bunch of kale, washed and dried
1 tbsp olive oil
2 dashes salt
2 dashes garlic powder

Instructions

Preheat oven to 300F and place a sheet of parchment paper on a baking sheet.
Take the washed and dried kale and rip them into “chip” size pieces and place in a large bowl.
Drizzle with olive oil, salt, and garlic powder. Mix until the kale pieces are evenly covered.
Place kale onto prepared sheet in an even layer. Bake for 10 minutes.
Flip over the kale to cook the other sides of the pieces. Bake for another 10 minutes until the edges just start turning brown. Monitor them well, or you’ll have burnt kale chips.

Serve & enjoy!

Tip: You can use any spice, so try onion powder, paprika, or even turmeric.
