00:00Is this safe to eat?
00:02We sometimes see strange dots on our potatoes
00:04and wonder if we should just throw them away.
00:07Here are 10 eat or toss facts.
00:10Did you know that every year,
00:13119 billion pounds of food is wasted only in the United States?
00:18To put it in perspective,
00:20this number means nearly 40% of all food in America is wasted.
00:25People throw away food if they don't have confidence in the ingredients.
00:30They're being cautious and it makes sense.
00:32But what if the food is safe to eat and only looks weird?
00:36The first item on the list is beef.
00:38When it comes to meat, people naturally get extra cautious.
00:42Imagine you buy some raw beef in the store.
00:45Later on, you realize it's got some brown spots.
00:48If you toss it immediately, hear me out.
00:51This is normal.
00:52In fact, you can see brown layers also inside the beef.
00:56Bright red color equals fresh meat, huh?
00:58Not necessarily.
01:00When the meat is first cut, it's maroon.
01:03If the meat is quickly vacuum packaged, it will keep that shade.
01:07But if the meat is exposed to air for like 15 minutes,
01:11then oxygen will cause a change in the look to red.
01:14The redness can turn brown when the biochemical reaction starts.
01:18This can take a few hours.
01:20Workers at the grocery stores grind the meat several times a day
01:23to achieve that bright red color because they know consumers are cautious about maroon-looking beef.
01:29If the beef is wrapped in an oxygen-permeable plastic, it turns bright red after exposure to oxygen.
01:36As long as the meat smells and feels fresh, and if it's been stored properly, it should be safe to
01:42eat.
01:43Have you ever come across dark lines under a shrimp shell?
01:47This one has a similar story to beef.
01:50Black lines on your shrimp's flesh are related to a natural phenomenon.
01:54They gradually occur after shrimps are taken from the water.
01:57Meat is exposed to oxygen, and the blackness gets more visible over time.
02:02Here also, the pattern of the animal itself can be a factor.
02:06These black lines can be a naturally occurring discoloration on the shrimp.
02:11Think of cats.
02:12They also have different color patterns, but they're the same in terms of species.
02:17Next time, you can conduct a mini-experiment in your kitchen.
02:20Put a couple of shrimps side by side and observe the mild differences in the shrimp's color patterns.
02:26Shrimp will have a distinct bad odor when it's no longer edible,
02:29so if it smells and tastes fresh, don't toss it.
02:33Should you eat moldy yogurt?
02:36That green substance on the surface doesn't look appealing at all.
02:39But if you scoop it out, you seem to have clean yogurt underneath.
02:43The short answer is toss it.
02:45The mold could be seen on the top only, but it has probably gone deep.
02:50Not to mention that it'll taste bad.
02:52Many molds are harmless, but some produce toxic substances.
02:56Green mold is a type of penicillium.
02:59Does this word sound familiar?
03:01That's the same type of mold used in the antibiotic penicillin.
03:05Don't get too excited.
03:07Eating moldy yogurt won't magically cure bacterial infections.
03:10It only spoils your dairy product.
03:13In 2013, there was an outbreak related to one line of yogurts.
03:18The company handed the products to stores as usual.
03:21After some time, they received customer complaints.
03:24They said that the yogurt looked like yogurt soup and tasted really old.
03:29Turns out that a type of fungus probably released some carbon dioxide.
03:34It made the product fizzy and bloating.
03:37Blech!
03:37The company and another independent scientist both said that this fungus in question wasn't usually harmful to people.
03:45Yet, more than 200 people reported becoming affected by it.
03:48So, these sorts of things can still happen.
03:52You should trust your spidey sense.
03:54If you've ever been lucky enough to see some mold in a freshly opened package, reach out to the manufacturer.
04:00You'll potentially save others from facing the same scenery by notifying the company about a systemic issue.
04:06And preventing potential future product waste.
04:08Plus, the company probably wants to make amends and either reimburse your sad yogurt with a happy one.
04:15Or better, they'll give you coupons for free products.
04:18Why do avocados sometimes have brown dots inside?
04:23Technically, it's edible.
04:24But you might not want to eat it.
04:27Avocados are a source of many vitamins like C, E, K, and B6.
04:32As well as healthy stuff like magnesium, potassium, and more.
04:36The avocado works hard to become such a health storage.
04:40Nutrients, water, and sugars wander around this fruit.
04:43Yes, technically, avocado is classified as a fruit.
04:47Anyway, avocados have their own transport channels, like veins.
04:51These channels are normally invisible to us.
04:54Until something goes out of the ordinary,
04:57the avocado may be stored in too cold temperatures for a longer time than it should.
05:01As a result, the tissue cells might be weakened and start to deteriorate.
05:06Experts say that after the fruit is harvested,
05:09if it stays in the refrigerator for a few weeks before you buy it,
05:12vascular browning can occur.
05:14This phenomenon becomes visible after you keep the avocado at room temperature for a few days.
05:19Don't be hard on yourself.
05:21It's not because of you.
05:22So, should you eat it or toss it?
05:24You can eat the brown dotted avocados, but you may want to taste them first.
05:28They might not taste good compared to a regular one.
05:32What about the white area under the potato peel?
05:35Eat or toss.
05:36This area is also like dark bruise marks, but it's not black.
05:40If the outer layer of the potato looks normal,
05:43that odd-looking white knot is not mold.
05:46The moldy potatoes deteriorate.
05:48They'll get softer, wrinkled, or squishy.
05:51As long as the exterior of this potato appears clean and regular,
05:55there's probably no harmful microbial growth inside of it.
05:58These strikingly white areas can be shaped due to potatoes being bruised,
06:03possibly in the field during the harvesting period.
06:05To sum up, you can eat it.
06:08There's also an issue of white smears coming out when we slice potatoes.
06:12You see the marks on the cutting board?
06:14Experts say that some potatoes have a higher level of water and starch content.
06:18As a result, your cutting board gets a bit messier than usual.
06:22No need to worry about it.
06:24I'm going to carry on with another form of potato.
06:27Not because I love every version of potato and I can eat it in all meals from breakfast to dinner,
06:32but because I want to know.
06:34What are those brown spots on potato chips?
06:37Should we eat or toss them?
06:39Consider these as minor imperfections.
06:42They don't affect the safety of the chip.
06:44They're there again because of the bruises they get or as a result of frying.
06:50Sometimes you see that your garlic is trying to make more garlic out of itself.
06:54Yep, it has sprouted.
06:56The question is, is it okay to eat sprouted cloves or should you toss them?
07:00If the green sprout is in the center of the garlic clove, that's fine.
07:04Be aware that the taste of the garlic will be stronger than it usually is.
07:08It will still be perfectly okay in a cooked meal since it'll be alongside other ingredients.
07:13The taste shouldn't be that harsh.
07:16Can we eat an apple with worms?
07:19Most people can't even stand the idea of accidentally eating an apple with a worm,
07:24but that's a cultural thing.
07:25So the answer is yes, we can eat it.
07:29After all, worms add a little protein to the fruit.
07:33These animals don't carry any harmful parasites.
07:36They make their way into the apple.
07:38The entrance point of the fruit might have an off flavor since it got sort of rotten in time.
07:43Besides the taste, the rotten part is all safe to bite.
07:47What might not be so safe is eating the fallen apples though.
07:51Those have probably been hanging out on the ground for quite some time.
07:55This period might be enough for the harmful bacteria from the soil to sneak into the apple.
08:01There were some cases where people experienced health issues by drinking unpasteurized apple juice made from dropped apples.
08:08Yeah, the ones that interact with unhealthy bacteria.
08:16From the iconic golden fries to a broken ice cream machine,
08:20here are 10 fast food secrets that the fast food industry doesn't really want you to know.
08:25Ah, chicken nuggets.
08:26Those golden crispy bites you can get from fast food chains.
08:30They're even on the menu of school lunches.
08:32What if I tell you that they aren't actually made entirely out of chicken?
08:36Researchers took chicken nugget samples from unnamed fast food chains and analyzed them.
08:42They said that one sample, for instance, contained only 40% and another 50% of meat.
08:48The rest?
08:49Well, you're eating mouthfuls of things like fat, connective tissue, and bone spicules.
08:55Many fast food companies grind the meat with that stuff.
08:58They make mechanically formed orbs of chicken parts.
09:01Why?
09:02Perhaps it's because this method is cheaper and more profitable.
09:06Millions of restaurants worldwide have chicken nuggets on their menu.
09:09So, scientifically, it's not fair to say all nuggets are made this way.
09:13But a lot of studies imply so.
09:16The more the meat is processed, the more you lose the good stuff, like vitamin B6 and B12.
09:22The bitter truth is that companies add stuff, such as sodium, to the mixed paste.
09:28Sodium is added to get a better flavor.
09:30It's one of the ingredients that makes nuggets so yummy.
09:34Our bodies need sodium, but not too much of it.
09:37Unfortunately, most junk food contains more than our bodies can handle.
09:41So, it might be a safe option to avoid eating these sorts of foods frequently.
09:46Chains dip their nuggets into tempura batter and fry them in hydrogenated oil.
09:51That's also not a green light regarding health, but this is how they catch the golden tint.
09:57They put additional stuff in nuggets.
10:00What about grilled chicken?
10:01In recent years, we've seen brands highlighting grilled chicken as a healthier option.
10:06Research has been done about grilled chicken, too.
10:08And the same approach is applied here.
10:11Take chicken samples from iconic fast food companies and send those to labs for analysis.
10:16The results show that companies are misleading people by advertising these products by labeling
10:23them as healthy, natural, and 100% chicken breast.
10:27In reality, a couple of things are added to the meat to make it tender and juicy.
10:32Plus, these additives make it easier to cook the meat, freeze, and transport it, and reheat
10:37it later without losing too much moisture.
10:39The drawback of all these additives is that they affect the nutritional value of the chicken
10:45breast.
10:46These ingredients aren't the healthiest for us.
10:49We should especially watch out for three things.
10:51The first one is, again, sodium.
10:53Fast food samples had 7 to 10 times more sodium than home-cooked chicken breast.
10:59Imagine you have a cheeseburger, but you say no to yourself and try to pick a less harmful
11:04menu item.
11:04Yet, some chicken sandwiches have the same amount or even more sodium than a cheeseburger
11:10with medium fries.
11:11The second thing you need to watch out for is phosphate additives.
11:15These additives allow the protein to conjoin more water.
11:19This means the white meat in the sandwich will appear juicier to you.
11:23Any word you see in the ingredients section that contains phos is a phosphate additive.
11:28So, it's best to avoid them.
11:31The last thing you should avoid is sugars and starches.
11:34Not just in grilled chicken, but pretty much in all fast food products.
11:38Oh, that's hard to digest, I admit.
11:41Cornstarch, sugar, malt, they come with grilled chicken breast.
11:44Buns and even some fries have sugar too.
11:48Everywhere I look, it's sugar.
11:50You see, home-cooked chicken has 0 grams of carbs, but the study samples had added sugar
11:56and up to 10% of the calories in the chicken breast comes from there.
11:59So, what's the moral of this story?
12:01If you're a health-conscious diner, you should maybe go for other options.
12:06There are secret recipes from companies like KFC and Coca-Cola.
12:10No company wants to share the ingredients that make their food irresistible,
12:15but with a little research, you can decipher many things.
12:19You want to know the secret of McDonald's fries?
12:21It's written on their website.
12:23They add beef flavoring to the frying oil.
12:26This may sound weird, but apparently, that's a known practice amongst chefs and restaurants.
12:31Duck fat has also been used as a flavor, for example, in high-end restaurants.
12:37I'm a fries lover, so I added another fact about fries.
12:41Sadly, they're even saltier than you think.
12:44Experts suggest that a grown-up should consume at most 2,300 milligrams of sodium daily.
12:50Guess the McD's large fry sodium number?
12:53At least 400 milligrams.
12:56Classic fries from Burger King have 732 milligrams,
13:00and Five Guys take the level even higher with 962 milligrams of sodium.
13:06Next time, maybe you can ask workers to go easy on the salt as a solution.
13:12Picture this.
13:13You're in a hurry, but your tummy says,
13:15Feed me, or I'll affect your mood and make life miserable for you.
13:19For a quick snack, you enter a fast food chain restaurant.
13:22You order your favorite burger.
13:24It looks and smells as if it's just been taken from the grill and served.
13:28Nope.
13:29They have different types of grills designed for this that can cook meat super quickly.
13:33Sorry to bear the bad news, but those perfect grill marks on your burger aren't real tools.
13:39The factory adds them.
13:41If you want to know how clean an eatery is,
13:44look under the ice chute of the soda machine in places where you can get your own drink.
13:48There you go, inspector.
13:49You solved the case.
13:51Various studies say that if such machines aren't cleaned correctly,
13:55dirty, contaminated ice can lead to some health problems.
13:58There could be mold or bacteria there.
14:01Ew, the process of cleaning ice machines isn't easy.
14:05The same thing applies to ice cream machines too.
14:08Rumor has it that those ice cream machines aren't out of order.
14:11Employers just cannot find time to clean them properly.
14:14Now, what's the best time to get a good and fresh meal?
14:18Here are two opinions, and they both have solid reasonings.
14:21The first team recommends avoiding ordering grilled food in chains from 7 to after midnight.
14:27Many former employees say that sometimes they had taquitos or hot dogs prepared at around 4 or 5 a.m.,
14:34but kept waiting to serve them till around midnight.
14:37That's not healthy.
14:39The other team says you should order between 11 a.m. and 1 p.m.,
14:43or between 6 p.m. and 8 p.m. to get the freshest meal.
14:47Since it's going to be around lunch and dinner time, there'll be circulation, and you can get decent food.
14:54Fast food companies have marketing, design, and psychological tricks to lure you in and make you order.
15:00Yet, they don't want you to stay inside for too long.
15:03If you were dining in mood lighting, you know under dim lamps and candlelight you would take your time to
15:09eat.
15:09As the name suggests, you should be fast like your food in chain restaurants.
15:13They have fluorescence, and they're in full light.
15:17Similarly, the floors and tables have reflective surfaces that make food look nice and bright.
15:23Plus, music is usually fast and loud.
15:26It's done to prevent you from spending hours there.
15:29Yet, they want you to take advantage of the first 20 minutes after your purchase.
15:34The faster you eat, the longer it will take you to feel full.
15:38Scientists say it takes about 20 minutes for our stomachs to inform our brain,
15:42OK, now I'm full.
15:45It's a good idea to eat in a clean area,
15:48but most of these companies are using cleaning products that have super strong chemicals.
15:53Assume that the staff cleaned the place at the end of their shift.
15:56They wiped down the soda machine and grill surface, and then you showed up early the next day.
16:02You may get some of that chemical residue on your food
16:05compared to other customers visiting the place later in the day.
16:09The vegan patty may not be 100% vegan.
16:13I'm talking about the grill, not the meat itself.
16:15In most of the chains, vegan burgers are cooked on the same grill as meat burgers.
16:21Do you have fast food chain secrets you want to share?
16:24Tell them to fellow brightsiders in the comments.
16:29There's a dangerous dish that can poison you when prepared incorrectly.
16:33Everyday food like honey and cashew can be harmful too, in certain conditions.
16:38You should know these facts before you eat some products.
16:41Have you ever chewed the seeds when eating an apple?
16:44Then you know that unpleasant taste the seeds have.
16:47That's because of cyanide.
16:49Don't be alarmed yet.
16:50The seeds have a protective cloak covering them.
16:53That's why cyanide doesn't enter your system if you accidentally swallow the seeds.
16:58Better be cautious though.
17:00Even small doses of cyanide can result in rapid breathing and more extreme and unpleasant results.
17:07Another danger lurking in your kitchen is potatoes.
17:10The ones with sprouts and green spots.
17:12Cutting off the green parts or sprouts solves the problem only visibly.
17:16The toxic substance called glycoalkaloid may have already spread through the whole potato.
17:22This substance turns some parts of a potato green for some reason.
17:27It's a sign for you.
17:28Eating this kind of potato can cause nausea, headaches, and other consequences.
17:34Are you a bubble tea fan?
17:36Then maybe you're familiar with cassava, a.k.a. tapioca.
17:40This is a root veggie and it's cultivated in South America.
17:44It's also often used to make cakes and chips.
17:47It can be either sweet or bitter.
17:50It's common for root and tuber varieties of cassava to contain toxins.
17:55Tapioca must be prepared properly before you consume it.
17:59If it's served incorrectly or eaten raw, the consequences are pretty serious.
18:04But when it's processed correctly, it's delicious and safe to eat.
18:09Elderberries are known as a supplement to boost your immune system and help your body fight a cold or the
18:15flu.
18:15This medicinal plant needs to be handled and prepared with care, too.
18:20If you eat unripe berries, they can do more harm than good.
18:24Here comes lectin and cyanide.
18:26These chemicals can cause stomach problems, for instance.
18:30This one makes me sad more than any other thing on the list.
18:33And this list includes a lot of healthy products.
18:36Anyway, here I spell it out.
18:39Popcorn
18:39There are many studies saying that microwave popcorn is harmful for you.
18:45First, you consume the chemicals used in packaging.
18:48There are also flavoring additives that aren't healthy.
18:52Now, remember that moment when you open the bag and hot popcorn-smelling air goes up into your nose?
18:58It can lead to irreversible lung damage.
19:01For instance, there's a diagnosis named popcorn lung.
19:04A chemical used to provide microwave popcorn with its buttery flavor is related to that diagnosis.
19:11What can you do?
19:12Choose other packaging options or invest in an air popper.
19:16Air popped popcorn has only 90 calories and less than 1 gram of fat.
19:22Yay!
19:23Number 6 is honey.
19:26Honey is a sweet liquid made by…
19:28I'm joking.
19:29But do you know that natural honey is dangerous to eat if the amount is more than a teaspoon?
19:34It has a toxin with a hard-to-pronounce name.
19:37To get rid of this toxin, honey has to go through a pasteurization process.
19:41Let's move on to cherry pits.
19:43If you don't chew or crunch them, you'll probably be fine.
19:47Yet, keep in mind that these pits contain prusic acid, and this stuff is poisonous.
19:54What about ackee fruit?
19:55It's the national fruit of Jamaica, and it turns out unripe ackee contains a poison called hypoglycin.
20:02Ackee fruit must be fully ripe if you want to eat it.
20:05In other words, this fruit should open up by itself.
20:09Once it's ready to be picked up, it'll split wide open.
20:12No to the highly toxic pink flesh or black seeds, and yes to the delicious creamy pulp near the seeds.
20:19Eating this fruit incorrectly can cause Jamaican stomach sickness.
20:25Fugu is the Japanese word for puffer fish, and the dish prepared from it.
20:29What's interesting about this dish is that it can be the last dish in your life if you don't prepare
20:35it properly.
20:36This fish contains a very powerful toxin that's very dangerous to humans.
20:41A single fish has enough poison to harm 30 people.
20:45Because of this, Japanese chefs undergo years of training to get a special license.
20:50Despite all precautions and preparations, fugu still sometimes becomes the last meal for some people.
20:57Would you take that risk?
21:00Perfect ciders, cashews.
21:02They can also be very risky to eat when they're raw.
21:05You probably get cashews from stores with raw cashew labels, but they aren't 100% raw.
21:11Before they find their spots on the shelves, they're processed with steam to remove a toxin called urushiol.
21:18Cashew shells contain this toxin.
21:20What would happen to you if you ate these nuts raw?
21:23A dangerous allergic reaction if you have a tendency to allergies.
21:27This depends on your sensitivity to poison ivy.
21:32Speaking of raw food, raw kidney beans are risky too.
21:36They contain a toxin called lectin.
21:38This one can give you stomach aches and other digestion-related issues as a bonus.
21:43All you need is to swallow 4 to 5 raw beans to experience these side effects.
21:49Red beans are rich in plant-based protein, essential vitamins, and minerals.
21:54Cook them correctly to enjoy these goodies.
21:56For this, keep dried red beans on the stove for at least 10 minutes.
22:01Boiling them for a shorter time and at a lower temperature can actually increase their toxicity.
22:06Beans can become even more toxic than if they are consumed raw.
22:10So yeah, a minimum of 10 minutes at high temperatures.
22:14Eating too many untreated bitter almonds can cause many unpleasant symptoms and health issues.
22:21Rhubarb leaves are a bit tricky too.
22:23You can eat the stock, but don't munch on the leaves.
22:26The leaves contain oxalic acid, which ties to calcium.
22:31This makes it harder for the body to absorb the needed amounts of calcium.
22:35Mushrooms.
22:36For plenty of people, pizza and pasta wouldn't be so great without mushrooms.
22:41We all know that mushrooms are kind of unpredictable, especially if they grow in the wild.
22:46Here are two of the most dangerous ones.
22:49The death cap and the destroying angel.
22:53Starfruit is a risky choice for people with sensitive kidneys.
22:56If you're one of them, you might want to keep this fruit out of your meals.
23:00Regularly functioning kidneys can filter out the toxins starfruit contains.
23:05Otherwise, the toxin will hang around and cause some problems there.
23:09The next product on the list is nutmeg.
23:12If you find that nutty flavor super nice like me, hear me out before adding it everywhere.
23:17Small amounts of nutmeg are fine and healthy.
23:21But if you, let's say, eat spoonfuls of nutmeg, it can cause problems.
23:25Even with two teaspoons.
23:27Knock, knock.
23:28You get poisoned.
23:30Canned tuna can be a lifesaver.
23:33It's not pricey.
23:34It's a good source of protein.
23:35And with its help, you can prepare a delicious meal quickly.
23:39No cooking.
23:40Just lettuce, bread, and a few more ingredients.
23:43There you go.
23:44How about three to five times a week?
23:47And you might experience a side effect called mercury poisoning.
23:51Now, this is related to how much and what type of food you consume.
23:55Canned tuna contains mercury, and that's why eating too much of it can lead to mercury poisoning.
24:01Medical advisors say that every kind of fish has some level of mercury.
24:06But that level differs from one species to another.
24:09For example, canned tuna has relatively high levels of mercury.
24:14Obviously, seafood is a great source of omega-3 and other things that are essential to our brain and good
24:20health.
24:20To stay safe, experts advise people to choose low-mercury seafood.
24:25Here's an interesting fact related to this.
24:27To get the most omega-3 fats from your canned tuna, choose water-packed fish instead of oil-packed.
24:34In oil-packed cans, the oil mixes with some of the tuna's natural fat.
24:39You open the can and drain the oil, and some of the fish's omega-3 fatty acids also get drained.
24:45But water and oil don't mix.
24:48Water-packed tuna won't lose its omega-3 fats.
24:51You can add some oil and dressing after you open the can.
