Science Reveals The Truth Behind 15 Common Food Myths

Science Reveals The Truth Behind 15 Common Food Myths

Here’s the thing about food. It’s essential, not magic.

There is no one food that’s going to make you healthier, and there is no one food that causes you to be less healthy.

Here is the science behind some of the most common food myths out there on the internet.

Myth: Microwaves zap the nutrients out of your food

You might be surprised to learn that microwaving your food is one of the best cooking methods when it comes to preserving nutrients. It just goes to show you cannot trust that everyone making claims on the internet has the scientific research to back them up.

Myth: Eggs are bad for your heart

Eggs aren’t as harmful to our cholesterol levels as we have come to believe. Actually, when you eat food containing cholesterol, your body compensates by making less cholesterol. Experts say if you eat an egg or two every day, it’s not going to hurt you.

Myth: Carbs make you fat

People are obsessed with low-carb diets because they believe eating carbs makes you fat. Carbohydrates are a form of energy and just another nutrient your body converts to glucose when you eat it. If you’re worried about eating too much sugar, good luck: in the end, everything you eat turns into sugar in a form your body uses to perform its daily functions.

Myth: Radiation from microwaves puts dangerous compounds in your food

Seriously, what does the internet have against microwaves? The short rebuttal: no. The kind of radiation given off by microwaves is not the kind of radiation that will harm you. And as mentioned above, microwaving your food is actually the best thing you can do for its nutritional value.

Myth: You can cleanse toxins from your body

Your body, to keep itself alive, has natural processes that remove toxins from your body as needed. You don’t need to stop eating a certain kind of food or drink a lot of water to make that happen. Your biology has you covered. Really. You cannot flush chemicals out of you. Everything is chemicals.

Myth: Vitamin C prevents colds

Research has yet to point to any proof that consuming vitamin C will keep you from getting a cold. It will probably make the cold you already have not last quite as long, but it’s not going to keep you from getting one. Washing your hands probably will, though.

Myth: A gluten-free diet is good for you even when you don’t need it

Those who need to be on gluten-free diets have something called Celiac disease, which means they are legitimately allergic to gluten (sort of). If you don’t have Celiac disease and you think going gluten-free is a good idea, think again: it can actually really hurt you.

Myth: Eating fat makes you fat

Actually, eating fat gives you energy, just like any other major nutrient out there. You might start to have a problem if you’re overeating fatty foods (or any kind of food for that matter), but cutting out fat from your diet won’t make you lose weight.

Myth: Nuts are bad for you

Nuts contain protein, which is essential for a healthy diet. The reason you don’t need to worry about nuts is that they contain more beneficial nutrients than ones you need to watch more closely. Too much of anything isn’t good for you. Take a handful and you’ll be fine. Don’t eat the whole container at once.

Myth: If it’s labeled “natural,” it’s healthy

The word “natural” on a food label does not say anything about how healthy a food is. Foods that are labeled as natural go through minimal amounts of processing, which means that even if they don’t contain any fake ingredients or colors, it still goes through processing. And the USDA isn’t too specific about what that means. Organic is your healthier option here.

Myth: You need to drink exactly eight glasses of water every day

How much water you need to drink every day actually depends on a lot of different factors. There is no magic amount of water that’s going to cure all your diseases or make you lose weight. You need to listen to your body. When you’re thirsty, drink some water. When you’re not thirsty anymore, don’t drink any more water. It’s that simple.

Myth: Never eat after 7 p.m.

Time of day has nothing to do with how your body absorbs and uses nutrients. Eating certain foods later in the day might make it harder for some people to fall asleep or get a good night’s rest, but the calories you dump into your body in the morning are the exact same calories you dump into it at night.

Myth: Celery has “negative” calories

Celery has fewer than 10 calories per serving, which does make them great choices for healthy snacks (especially if you pair them with your favorite dip or spread). They are extremely low in calories, but you don’t burn calories by eating a stick of celery.

Advertising

Myth: Raw vegetables are more nutritious than cooked vegetables

In reality, certain vegetables have more of certain kinds of nutrients when their cooked as opposed to when you eat them raw. It all depends on how you cook them. Methods like boiling do cause vegetables to lose some of their water-soluble vitamins, but that doesn’t necessarily mean they are any less nutritious overall.

Myth: Margarine is healthier than butter

When comparing margarine and butter, margarine is usually considered healthier because it is made from vegetable oils. Most margarine still contains trans fat, though, which actually lowers the good kind of cholesterol in your body. Your best bet would be to limit whichever spread you choose.

If you’re ever unsure of whether something related to food is true or not, look up sources that are backed by scientific evidence, or information that comes from professional organizations. Hate to break it to you, but your favorite food blogger, unless she’s a licensed nutrition professional, is probably wrong.

Why You’re Feeling Tired All the Time (And What to Do About It)

Why You’re Feeling Tired All the Time (And What to Do About It)

Feeling tired all the time?

Have you ever caught yourself nodding off when you’re watching TV, listening to someone drone on during a meeting or even driving a car?

I know I have, especially when I worked 70 hours per week as a High-Tech Executive.

Feeling tired all the time may be more widespread than you think. In fact, two-fifths of Americans are tired most of the week.[1]

If you’re tired of feeling tired, then I’ve got some great news for you. New research is helping us gain critical insights into the underlying causes of feeling tired all the time.

In this article, we’ll discuss the latest reasons why you’re feeling tired all the time and practical steps you can take to finally get to the bottom of your fatigue and feel rested.

What Happens When You’re Too Tired

If you sleep just two hours less than the normal eight hours, you could be as impaired as someone who has consumed up to three beers.[2] And you’ve probably experienced the impact yourself.

Here are some common examples of what happens when you’re feeling tired:[3]

  • You may have trouble focusing because memory and learning functions may be impaired within your brain.
  • You may experience mood swings and an inability to differentiate between what’s important and what’s not because your brain’s neurotransmitters are misfiring.
  • You may get dark circles under your eyes and/or your skin make look dull and lackluster in the short term and over time your skin may get wrinkles and show signs of aging because your body didn’t have time to remove toxins during sleep.
  • You may find it more difficult to exercise or to perform any type of athletic activity.
  • Your immune system may weaken causing you to pick up infections more easily.
  • You may overeat because not getting enough sleep activates the body’s endocannabinoids even when you’re not hungry.
  • Your metabolism slows down so what you eat is more likely to be stored as belly fat.

Are you saying that feeling tired can make me overweight?

Unfortunately, yes!

Feeling tired all the time can cause you to put on the pounds especially around your waist. But it is a classic chicken and egg situation, too.

Heavier people are more likely to feel fatigued during the day than lighter ones. And that’s even true for overweight people who don’t have sleep apnea (source: National Institutes of Health).

Speaking of sleep apnea, you may be wondering if that or something else is causing you to feel tired all the time.

Why Are you Feeling Tired All the Time?

Leading experts are starting to recognize that there are three primary reasons people feel tired on a regular basis: sleep deprivation, fatigue and Chronic Fatigue Syndrome (CFS).

Here’s a quick overview of each root cause of feeling tired all of the time:

  1. Tiredness occurs from sleep deprivation when you don’t get high-quality sleep consistently. It typically can be solved by changing your routine and getting enough deep restorative sleep.
  2. Fatigue occurs from prolonged sleeplessness which could be triggered by numerous issues such as mental health issues, long-term illness, fibromyalgia, obesity, sleep apnea or stress. It typically can be improved by changing your lifestyle and using sleep aids or treatments, if recommended by your physician.
  3. Chronic Fatigue Syndrome (CFS) is a medical condition also known as Myalgic Encephalomyelitis that occurs from persistent exhaustion that doesn’t go away with sleep.

The exact cause of CFS is not known, but it may be due to problems with the immune system, a bacterial infection, a hormone imbalance or emotional trauma.

It typically involves working with a doctor to rule out other illnesses before diagnosing and treating CFS.[4]

Always consult a physician to get a personal diagnosis about why you are feeling tired, especially if it is a severe condition.

Feeling Tired vs Being Fatigued

If lack of quality sleep doesn’t seem to be the root cause for you, then it’s time to explore fatigue as the reason you are frequently feeling tired.

Until recently, tiredness and fatigue were thought to be interchangeable. Leading experts now realize that tiredness and fatigue are different.

Tiredness is primarily about lack of sleep.

But fatigue is a perceived feeling of being tired that is much more likely to occur in people who have depression, anxiety or emotional stress and/or are overweight and physically inactive (source: Science Direct).

Symptoms of fatigue include:

  • Difficulty concentrating
  • Low stamina
  • Difficulty sleeping
  • Anxiety
  • Low motivation

These symptoms may sound similar to those of tiredness but they usually last longer and are more intense.

Unfortunately, there is no definitive reason why fatigue occurs because it can be a symptom of an emotional or physical illness. But there are still a number of steps you can take to reduce difficult symptoms by making a few simple lifestyle changes.

How Much Sleep Is Enough?

The number one reason you may feel tired is because of sleep deprivation which means you are not getting enough high-quality sleep.

Most adults need 7 to 9 hours of high-quality, uninterrupted sleep per night. If you’re sleep deprived, the amount of sleep you need increases.

So, quantity and quality do matter when it comes to sleep.

The key to quality sleep is being able to get long, uninterrupted sleep cycles throughout the night. It typically takes 90 minutes for you to reach a state of deep REM sleep where your body’s healing crew goes to work.

Ideally, you want to get at least 3 to 4 deep REM sleep cycles in per night. That’s why it’s so important to stay asleep for 7 or more hours.

Research also shows that people who think they can get by on less sleep don’t perform as well as people who get at least seven hours of sleep a night[5] So, you should definitely plan on getting seven hours of deep restorative sleep every night.

If you are not getting 7 hours of high-quality sleep regularly, then sleep deprivation is most likely reason you feel tired all the time.

And that is good news because sleep deprivation is much simpler and easier to address than the other root causes.

It’s also a good idea to rule out sleep deprivation as the reason why you are tired before moving on to the other possibilities such as fatigue or Chronic Fatigue Syndrome, which may require a doctor for diagnosis and treatment.

4 Simple Changes to Reduce Fatigue

Personally, I’m a big believer in upgrading your lifestyle to uplift your life. I overcame chronic stress and exhaustion by making these four changes to my lifestyle:

  1. Eating healthy, home-cooked meals versus microwaving processed foods or eating out
  2. Exercising regularly
  3. Using stressbusters
  4. Creating a bedtime routine to sleep better

So, I know it is possible to change your lifestyle even when you’re working crazy hours and have lots of family responsibilities.

After I made the 4 simple changes in my lifestyle, I no longer felt exhausted all of the time.

In addition, I lost two inches off my waist and looked and felt better than ever.

I was so excited that I wanted to help others replace stress and exhaustion with rest and well-being, too. That’s why I became a Certified Holistic Wellness Coach through the Dr. Sears Wellness Institute.

Interestingly enough, I discovered that Dr. Sears recommends a somewhat similar L.E.A.N. lifestyle:

  • L is for Lifestyle and means living healthy including getting enough sleep.
  • E is for Exercise and means getting at least 20 minutes of exercise a day ideally for six days a week.
  • A is for Attitude and means thinking positive and reducing stress whenever possible.
  • N is for Nutrition and means emphasizing a right-fat diet, not a low-fat diet.

The L.E.A.N. lifestyle is a scientifically-proven way to reduce fatigue, get to the optimal weight and to achieve overall wellness.[6]

And yes, there does seem to be an important correlation between being lean and feeling rested.

But overall based on my personal experience and Dr. Sear’s scientific proof, the key to not feeling tired all of the time does seem to be 4 simple changes to your lifestyle.

L — Living Healthy

Getting enough high-quality sleep every day is the surefire way to help you feel less fatigued, more rested and better overall.

So, whether you’re sleep deprived or potentially suffering from fatigue or Chronic Fatigue Syndrome, you probably want to find a way to sleep better.

In fact, if you aren’t getting enough sleep, your body isn’t getting the time it needs to repair itself; meaning that if you are suffering from an illness, it’s far more likely to linger.

As unlikely as it sounds, though, fatigue can sometimes make it difficult to sleep. That’s why I’d recommend taking a look at your bedtime routine before you go to bed and optimize it based on sleep best practices.

Here are 3 quick and easy tips for creating a pro-sleep bedtime routine:

1. Unplug

Many of us try to unwind by watching TV or doing something on an iPhone or tablet. But tech can affect your melatonin production due to the blue light that they emit, fooling your body into thinking it’s still daytime.

So turn off all tech one hour before bed and create a tech-free zone in your bedroom.

2. Unwind

Do something to relax.

Use the time before bed to do something you find relaxing such as reading a book, listening to soothing music, meditating or taking an Epsom salt bath.

3. Get Comfortable

Ensure your bed is comfortable and your room is set up for sleep.

Make sure you room is cool. 60-68 degrees is the ideal temperature for most people to sleep.

Also, it’s ideal if your bedroom is dark and there is no noise.

Finally, make sure everything is handled (e.g., laying out tomorrow’s clothes) before you get into your nice, comfy bed.

If your mind is still active, write a to-do list to help you fall asleep faster.[7]

Above all, be gentle with yourself and count your blessings, some sheep or whatever helps.

E — Exercise

Many people know that exercise is good for them, but just can’t figure out how to fit it into their busy schedules.

That’s what happened in my case.

But when my chronic stress and exhaustion turned into systemic inflammation (which can lead to major diseases like Alzheimer’s), I realized it was time to change my lifestyle.

As part of my lifestyle upgrade, I knew I needed to move more.

My friends who exercise all gave me the same advice: find an exercise you like to do and find a specific time in your schedule when you can consistently do it.

That made sense to me.

So, I decided to swim.

I used to love to swim when I was young, but I hadn’t done it for years. The best time for me to do it was immediately after work, since I could easily get an open swim lane at my local fitness club then.

Also, swimming became a nice reason for me to leave work on time. And I got to enjoy a nice workout before eating dinner.

Swimming is a good way to get your cardio or endurance training. But, walking, running and dancing are nice alternatives.

So find an exercise you love and stick to it. Ideally, get a combination of endurance training, strength training and flexibility training in during your daily 20-minute workout.

If you haven’t exercised in a while and have a lot of stress in your life, you may want to give yoga a try because you will increase your flexibility and lower your stress.

A — Attitude

Stress may be a major reason why you aren’t feeling well all of the time. At least that was the case with me.

When I worked 70 hours per week as a High-Tech Executive, I felt chronically stressed and exhausted. But there was one thing that always worked to help me feel calmer and less fatigued.

Do you want to know what that master stress-busting technique was?

Breathing.

But not just any old breathing. It was a special form of deep Yogic breathing called the “Long-Exhale Breathing” or “4-7-8 breathing” or “Pranayama” in Sanskrit).

Advertising

Here’s how you do “Long-Exhale Breathing”:

  1. Sit in a comfortable position with your spine straight and your hand on your tummy (so you know you are breathing deeply from your diaphragm and not shallowly from your chest)
  2. Breathe in deeply and slowly from your diaphragm with your mouth closed while you count to 4 (ideally until your stomach feels full of air)
  3. Hold your breath while you count to 7 mentally and enjoy the stillness
  4. Breathe out through your mouth with a “ha” sound while you count to 8 (or until your stomach has no more air in it)
  5. Pause after you finish your exhale while you notice the sense of wholeness and relaxation from completing one conscious, deep, long exhale breath
  6. Repeat 3 times ensuring your exhale is longer than your inhale so you relax your nervous system

This type of “long-exhale breathing” is scientifically proven to reduce stress.

When your exhale is twice as long as your inhale, it soothes your parasympathetic nervous system, which regulates the relaxation response.[8]

Plus, this is a great technique for helping you get to sleep, too.

N — Nutrition

Diet is vital for beating fatigue – after all, food is your main source of energy.

If your diet is poor, then it implies you’re not getting the nutrients you need to sustain healthy energy levels.

Eating a diet for fatigue doesn’t need to be complicated, time-consuming though.

For most people, it’s just a case of swapping a few unhealthy foods for a few healthier ones, like switching from low-fiber, processed foods to whole, high-fiber foods.

Unless your current diet is solely made up of fast food and ready meals, adjusting to a fatigue-fighting diet shouldn’t be too much of a shock to the system.

Here’re 9 simple diet swaps you can make today:

  1. Replace your morning coffee with Matcha green tea and drink only herbal tea within six hours of bedtime.
  2. Add a healthy fat or protein to your any carb you eat, especially if you eat before bed. Please note that carb-only snacks lead to blood-sugar crashes that can make you eat more and they can keep you from sleeping.
  3. Fill up with fiber especially green leafy vegetables. Strive to get at least 25g per day with at least 5 servings (a serving is the size of your fist) of green vegetables.
  4. Replace refined, processed, low-fiber pastas and grains with zucchini noodles and whole grains such as buckwheat, quinoa, sorghum, oats, amaranth, millet, teff, brown rice and corn.
  5. Swap natural sweeteners for refined sugars and try to ensure you don’t get more than 25g of sugar a day if you are a woman and 30g of sugar a day if you are a man.
  6. Replace ice cream with low-sugar alternatives such as So Delicious Dairy-Free Vanilla Bean Coconut Ice Cream.
  7. Swap omega-6, partially-hydrogenated oils such as corn, palm, sunflower, safflower, cotton, canola and soybean oil for omega-3 oils such as flax, olive and nut oils.
  8. Replace high-sugar yoghurts with low-sugar, dairy-free yoghurts such as Kite Hill Plain Yoghurt with 1g sugar or Lifeway Farmer Cheese with 0g sugar.
  9. Swap your sugar-laden soda for sparkling water with a splash of low-sugar juice

Also, ensure your diet is giving you enough of the daily essential vitamins and minerals. Most of us don’t get enough Vitamin D, Vitamin B-12, Calcium, Iron and Magnesium. If you are low on any of the above vitamins and minerals, you may experience fatigue and low energy.

That’s why it’s always worth having your doctor check your levels. If you find any of them are low, then try to eat foods rich in them.

Alternatively, you might consider a high-quality multi-vitamin or specific supplement.

The Bottom Line

If you are tired of feeling tired, then there is tremendous hope.

If you are tired because you are not getting enough high-quality sleep, then the best remedy is a bedtime routine based on sleep best practices.

If you are tired because you have stress and fatigue, then the best remedy are four simple lifestyle changes including:

  • Enough High-Quality Sleep with Bedtime Routine
  • Regular Exercise You Love
  • Stress Reduction with Long-Exhale Breathing
  • Fatigue-Reducing Diet

Overall, adopting a healthier lifestyle Is the ideal remedy for feeling more rested and energized.
