15 'Health Foods' That Are Really Junk Foods in Disguise
Surprisingly, people consider some of these foods healthy.
Here are 15 "health foods" that are really junk foods in disguise.
1. Processed ‘Low-Fat’ and ‘Fat-Free’ Foods
The "war" on saturated fat could be considered one of the most misguided decisions in the history of nutrition.
It was based on weak evidence, which has now been completely debunked.
When this discussion started, processed food manufacturers jumped on the bandwagon and started removing the fat from foods.
But there's a huge problem. Food doesn't taste well when the fat has been removed. That's why they added a lot of sugar to compensate.
Saturated fat is harmless, but added sugar is incredibly harmful when consumed in excess.
The words "low fat" or "fat free" on packaging usually means that it's a highly processed product that's loaded with sugar.
2. Most Commercial Salad Dressings
Vegetables are incredibly healthy.
The problem is that they often don't taste very good on their own.
That's why many people use dressings to add flavor to their salads, turning these bland meals into delicious treats.
But many salad dressings are actually loaded with unhealthy ingredients like sugar, vegetable oils, and trans fats, along with various artificial chemicals.
Although vegetables are good for you, eating them with a dressing high in harmful ingredients negates any health benefit you get from the salad.
Check the ingredients list before you use a salad dressing or make your own using healthy ingredients.
3. Fruit Juices … Which Are Basically Just Liquid Sugar
A lot of people believe fruit juices are healthy.
They must be because they come from fruit, right?
But most fruit juice you find in the grocery store isn't really fruit juice.
Sometimes they don't have any actual fruit in them, just chemicals that taste like fruit. What you're drinking is basically fruit-flavored sugar water.
That being said, even if you're drinking 100% quality fruit juice, it's still not the best choice.
Fruit juice actually contains a similar amount of sugar as a sugar-sweetened beverage.
4. ‘Heart-Healthy’ Whole Wheat
Most "whole wheat" products aren't really made from whole wheat.
The grains have been pulverized into very fine flour, which causes them to raise blood sugar just as fast as their refined counterparts.
In fact, whole wheat bread can have a similar glycemic index as white bread.
But even true whole wheat may be a bad idea because modern wheat is unhealthy compared to the wheat our grandparents ate.
Around 1960, scientists modified the genes in wheat to increase the yield. Modern wheat is less nutritious and has some properties that make it much worse for people who have a gluten intolerance.
There are also studies showing that modern wheat may cause inflammation and increased cholesterol levels, at least when compared to the older varieties.
Wheat may have been a relatively healthy grain back in the day, but the stuff most people are eating today should be consumed with caution.
5. Cholesterol-Lowering Phytosterols
Phytosterols are nutrients that are basically like plant versions of cholesterol.
Some studies have shown that they can lower blood cholesterol in humans.
For this reason, they're often added to processed foods that are then marketed as "cholesterol lowering" and claimed to help prevent heart disease.
However, studies have shown that despite lowering cholesterol levels, phytosterols have negative effects on the cardiovascular system and may even increase the risk of heart disease and death.
People with phytosterolaemia (a genetic condition that raises plant sterol level in blood) are more susceptible to the negative effects of phytosterols.
Butter was labeled a bad food choice in the past because of its high saturated fat content.
Various health experts started promoting margarine instead.
Back in the day, margarine used to be high in trans fats. These days, it has fewer trans fats than before, but it's still loaded with refined vegetable oils.
Not surprisingly, the Framingham Heart Study showed that people who replace butter with margarine are actually more likely to die from heart disease.
If you want to improve your health, try to eat real butter (preferably grass fed), and avoid margarine with trans fat. Trans-fat-free margarine has become more available in recent years.
Always read nutrition facts carefully and limit products that contain trans fat.
Recommending trans fat-laden margarine instead of natural butter may be considered some of the worst nutrition advice in history.
7. Sports Drinks
Sports drinks were designed with athletes in mind.
They contain electrolytes (salts) and sugar, which can be useful for athletes in many cases.
However, most people don't need additional salt or liquid sugar in their diet.
Although often considered "less bad" than sugary soft drinks, there's really no fundamental difference in the two, except the sugar content in sports drinks is sometimes slightly lower.
It's important to stay hydrated, especially when working out, but most people will be better off sticking to plain water.
8. Low-Carb Junk Foods
Low carb diets have been incredibly popular for many decades.
In the past 12 years, studies have confirmed that these diets are an effective way to lose weight and improve health.
However, food manufacturers have caught up on the trend and brought various low carb "friendly" processed foods to the market.
This includes highly processed foods like the Atkins bars. If you take a look at the ingredients list, you see that there's no real food in them, just chemicals and highly refined ingredients.
These products can be consumed occasionally without compromising the metabolic adaptation that comes with low carb eating.
However, they don't really nourish your body. Even though they're technically low carb, they're still unhealthy.
9. Agave Nectar
Given the known harmful effects of sugar, people have been looking for alternatives.
One of the more popular "natural" sweeteners is agave nectar, which is also called agave syrup.
You'll find this sweetener in all sorts of "healthy foods," often with attractive claims on the packaging.
The problem with agave is that it's no better than regular sugar. In fact, it's much worse.
One of the main problems with sugar is that it has excessive amounts of fructose, which can cause severe metabolic problems when consumed in excess.
Sugar is about 50% fructose and 55% high fructose corn syrup, but agave contains even more — up to 70-90%.
Therefore, gram for gram, agave is even worse than regular sugar.
"Natural" doesn't always equal healthy. Whether agave should even be considered natural is debatable.
10. Vegan Junk Foods
Vegan diets are very popular these days, often due to ethical and environmental reasons.
However, many people promote vegan diets for the purpose of improving health.
There are many processed vegan foods on the market, often sold as convenient replacements for non-vegan foods.
Vegan bacon is one example.
But it's important to keep in mind that these are usually highly processed, factory made products that are bad for almost anyone, including people who are vegan.
11. Brown Rice Syrup
Brown rice syrup, also known as rice malt syrup, is a sweetener that's mistakenly assumed to be healthy.
It's made by exposing cooked rice to enzymes that break down the starch into simple sugars.
Brown rice syrup contains no refined fructose, just glucose.
Rice syrup is also highly refined and contains almost no essential nutrients. In other words, it's considered "empty" calories.
Some concerns have been raised about arsenic contamination in this syrup, which is another reason to be extra careful with this sweetener.
There are other sweeteners out there, including low calorie sweeteners like:
In general, try to use all sweeteners wisely and follow recommended serving sizes.
12. Processed Organic Foods
Unfortunately, the word "organic" has become a typical marketing buzzword in many instances.
Food manufacturers have found all sorts of ways to make the same products, except with ingredients that happen to be organic.
This includes ingredients like organic raw cane sugar, which is basically 100% identical to regular sugar. It's still just glucose and fructose with little to no nutrients.
In many cases, the difference between an ingredient and its organic counterpart is next to none.
Processed foods that happen to be labeled organic aren't necessarily healthy. Always check the label to see what's inside.
13. Vegetable Oils
However, it's important to keep in mind that blood cholesterol is a risk factor. It's not a disease in itself.
Even though vegetable oils can help improve a risk factor, there's no guarantee that they'll help prevent actual health outcomes like heart attacks or death, which is what really counts.
In fact, several controlled trials have shown that despite lowering cholesterol, these oils can increase the risk of developing heart disease and memory impairment.
Also, follow the recommended serving size, but limit processed vegetable oils as if your health depended on it, which it does.
14. Gluten-Free Junk Foods
According to a 2013 survey, about a third of people in the United States are actively trying to limit or avoid gluten.
Many experts believe this is unnecessary, but the truth is, gluten, especially from modern wheat, can be problematic for a lot of people.
Not surprisingly, the food manufacturers have brought all sorts of gluten-free foods to the market.
The problem with these foods is that they usually have the same negative effects on your body as their gluten-containing counterparts, if not worse.
These are highly processed foods containing few nutrients and often made with refined starches that can lead to very rapid spikes in blood sugar.
Try to choose foods that are naturally gluten free, like plants and animals, not gluten-free processed foods.
Gluten-free junk food is still junk food.
15. Most Processed Breakfast Cereals
The way some breakfast cereals are marketed can be deceiving.
Many of them, including those that are marketed toward children, have various health claims listed on the box.
This includes claims like "whole grain" or "low fat" that may be misleading.
This is especially true when you look at the ingredients list and see that these products mostly contain:
- refined grains
- artificial chemicals
It's important to always review product packaging to confirm what you're actually putting in your body and whether it's healthy for you.
Truly healthy foods are whole, single-ingredient foods. Their health benefits speak for them.
Real food doesn't even need an ingredients list, because real food is the ingredient.
The ghoulishly named ogre-faced spider can "hear" with its legs and use that ability to catch insects flying behind it, the study published in Current Biology Thursday concluded.
"Spiders are sensitive to airborne sound," Cornell professor emeritus Dr. Charles Walcott, who was not involved with the study, told the Cornell Chronicle. "That's the big message really."
The net-casting, ogre-faced spider (Deinopis spinosa) has a unique hunting strategy, as study coauthor Cornell University postdoctoral researcher Jay Stafstrom explained in a video.
They hunt only at night using a special kind of web: an A-shaped frame made from non-sticky silk that supports a fuzzy rectangle that they hold with their front forelegs and use to trap prey.
They do this in two ways. In a maneuver called a "forward strike," they pounce down on prey moving beneath them on the ground. This is enabled by their large eyes — the biggest of any spider. These eyes give them 2,000 times the night vision that we have, Science explained.
But the spiders can also perform a move called the "backward strike," Stafstrom explained, in which they reach their legs behind them and catch insects flying through the air.
"So here comes a flying bug and somehow the spider gets information on the sound direction and its distance. The spiders time the 200-millisecond leap if the fly is within its capture zone – much like an over-the-shoulder catch. The spider gets its prey. They're accurate," coauthor Ronald Hoy, the D & D Joslovitz Merksamer Professor in the Department of Neurobiology and Behavior in the College of Arts and Sciences, told the Cornell Chronicle.
What the researchers wanted to understand was how the spiders could tell what was moving behind them when they have no ears.
It isn't a question of peripheral vision. In a 2016 study, the same team blindfolded the spiders and sent them out to hunt, Science explained. This prevented the spiders from making their forward strikes, but they were still able to catch prey using the backwards strike. The researchers thought the spiders were "hearing" their prey with the sensors on the tips of their legs. All spiders have these sensors, but scientists had previously thought they were only able to detect vibrations through surfaces, not sounds in the air.
To test how well the ogre-faced spiders could actually hear, the researchers conducted a two-part experiment.
First, they inserted electrodes into removed spider legs and into the brains of intact spiders. They put the spiders and the legs into a vibration-proof booth and played sounds from two meters (approximately 6.5 feet) away. The spiders and the legs responded to sounds from 100 hertz to 10,000 hertz.
Next, they played the five sounds that had triggered the biggest response to 25 spiders in the wild and 51 spiders in the lab. More than half the spiders did the "backward strike" move when they heard sounds that have a lower frequency similar to insect wing beats. When the higher frequency sounds were played, the spiders did not move. This suggests the higher frequencies may mimic the sounds of predators like birds.
University of Cincinnati spider behavioral ecologist George Uetz told Science that the results were a "surprise" that indicated science has much to learn about spiders as a whole. Because all spiders have these receptors on their legs, it is possible that all spiders can hear. This theory was first put forward by Walcott 60 years ago, but was dismissed at the time, according to the Cornell Chronicle. But studies of other spiders have turned up further evidence since. A 2016 study found that a kind of jumping spider can pick up sonic vibrations in the air.
"We don't know diddly about spiders," Uetz told Science. "They are much more complex than people ever thought they were."
Learning more provides scientists with an opportunity to study their sensory abilities in order to improve technology like bio-sensors, directional microphones and visual processing algorithms, Stafstrom told CNN.
"The point is any understudied, underappreciated group has fascinating lives, even a yucky spider, and we can learn something from it," he told CNN.
