It’s actually a thing. I’ve never knew about this until today, when I saw #NationalToastDay trending on Twitter. There’s a national day for a product, which is absolutely horrible in terms of nutritional value. And it’s glorified on a national level. Guess why?
Because bread manufacturers figured out how to run a national advertising campaign showing off their products for FREE. Just take a look at all the creative pictures people post. Maybe I just don’t get it, right?
No, no, no, let’s take a closer look at why glorifying these type of products is a very, very, very bad idea.
What’s in your bread?
I’m not a baker, but I do know a few things about cooking and baking, because I used to binge watch Chef John and other cooks on YouTube. Generally, homemade bread requires very few ingredients, here’s an example:
- 1 package active dry yeast
- 2-1/4 cups warm water
- 3 tablespoons sugar
- 1 tablespoon salt
- 2 tablespoons canola oil
- 6-1/4 to 6-3/4 cups all-purpose flour
Hmm, but what do they put in a commercially produced bread? Let’s see.
INGREDIENTS: White Bread (Enriched Wheat Flour (Flour, Malted Barley Flour, Niacin, Iron (Ferrous Sulfate, Reduced Iron), Thiamine Mononitrate, Riboflavin, Folic Acid), Water, Yeast, Salt, Soybean Oil, Sugar, Malt, Dough Conditioners (Ascorbic Acid, Calcium Sulfate, Sodium Stearoyl Lactylate), Calcium Propionate (To Retard Mold Growth)). 
So many letters, so little meaning. How on Earth an average person is able to tell what’s Thiamine Mononitrate, or Riboflavin? And what effect does it have on the human body? Yet, a huge portion of people buy this junk, feed this junk to their kids and wonder why they suddenly gain weight. It’s probably genetics, right?
To make matters worse, this type of product is being glorified on social media, because… reasons. But I am not over yet. Let’s dig further.
Low nutritional value.
White bread, in particular has very low nutritional value, which inevitably leads to overeating. According to USDA one slice of white bread (30g) contains a 77 calories . Of which 74 percent are simple carbohydrates with glycaemic index of 70. 
In other words, a slice of white bread will be digested by your body so fast that you’ll be left wondering whether you ate something at all. Here’s a good analogy I like to use.
Image yourself alone in the forest, when it’s very cold during night time. You’ve got yourself a fire going and you really want to sleep. Your main goal is to keep warm through the night, so you have two options: keep throwing paper into the fire, which burns almost instantly, or find a decent size log, which will last through the night and then some.
Of course a decent size log is the best option, because it allows you to get rest, rather than constantly having to throw paper into the fire. If you still didn’t get it, white bread equals paper in this analogy.
Why white bread is addicting?
White bread is quite addicting and there’s a very good reason for that. As you may know, our gustatory system can identify 5 different tastes: salty, sweet, sour, bitter and savoury.  Food manufacturers know how to satisfy all of these senses by adding flavor enhancers along with a plethora of preservatives (to increase shelf life). However, the main ingredient, which makes white bread so addicting is sugar, or in most cases today, high fructose corn syrup.
Sugar is noteworthy as a substance that releases opioids and dopamine and thus might be expected to have addictive potential. 
Available evidence in humans shows that sugar and sweetness can induce reward and craving that are comparable in magnitude to those induced by addictive drugs. 
While these hypotheses do not prove anything, I firmly believe that these observations are absolutely true. Just ask your kid, does he want to have eggs for breakfast, or sugar filled cereal? My point, exactly.
How fat can we go?
Granted that there are no limitations on gluttony and promotion of low nutrition products, things are not looking good.
Linear time trend forecasts suggest that by 2030, 51% of the population will be obese. The model estimates a much lower obesity prevalence of 42% and severe obesity prevalence of 11%. If obesity were to remain at 2010 levels, the combined savings in medical expenditures over the next 2 decades would be $549.5 billion. 
Which translates to “we’re screwed”. Now that you have this information, what are you going to do about it?
