Can eating the rainbow help to reduce inflammation?

Inflammation is a natural process initiated by the immune system in response to illness, trauma, toxins, physical stress and chronic disease. While acute inflammation is protective and allows our bodies to heal, it can become harmful if it persists, leading to chronic inflammation. Chronic inflammation, in turn, can lead to conditions such as arthritis, heart disease, and diabetes.
Several foods can contribute to inflammation. These include highly processed foods, refined carbohydrates, or foods high in added sugars. Conversely, other foods can help calm the immune system, decreasing inflammation.
Let’s explore which foods help lower inflammation and how they can be incorporated into an anti-inflammatory diet.
Fruits and Vegetables: Colorful fruits and vegetables naturally contain various phytonutrients and bioactive compounds that help keep inflammation in check. These foods form the foundation of the anti-inflammatory diet and can be enjoyed in abundance. For an extra boost of protection, try drizzling antioxidant-rich olive oil on your veggies..
Protein: Choose primarily from plant-based sources such as legumes, soy, nuts, and seeds, with smaller amounts from lean cuts of animal protein and fatty fish. The fats in these proteins, mainly monounsaturated and omega-3, play a significant role in combating inflammation. The American Heart Association recommends 6 to 8 ounces of fatty fish and 5 ounces of legumes, nuts, and seeds per week.
Whole grains: Whole grains contain all parts of the grain, whereas refined grains remove the germ and bran, eliminating important inflammation-reducing compounds. Of these, fiber is a bit of a superstar, shown to help reduce blood sugar and cholesterol levels. Aim for at least 50% of your grains from whole grain sources, such as rolled oats and brown rice.
Herbs and Spices: Herbs and spices add flavor to your food and help reduce oxidative stress, which can trigger inflammation. Add ginger, turmeric, clove, cinnamon, oregano, and garlic to your next meal.
What change can you make today to shift your body into a less inflamed state?
Consider adding one colorful fruit or vegetable to your diet each day. Suggestions include tomatoes, oranges, yellow bell peppers, arugula, blueberries, pumpkin and broccoli.

A creamy smoothie with crunchy toppings — in a bowl!
Ingredients
Smoothie base
1 1/2 cups plain yogurt
1 banana, frozen
1/2 cup orange juice
1 cup berries of your choice
1 tablespoon flaxseeds
1 scoop vanilla plant-based protein powder, optional
Toppings
1 tablespoon slivered almonds
1 teaspoon chia seeds
1 tablespoon pomegranate seeds
Directions
Blend all base ingredients together until smooth, adjusting for sweetness and thickness.
Serve immediately in a large bowl with toppings.
Ingredient health benefits
Yogurt: With probiotics and prebiotics to go around, yogurt is a great way to show your stomach some love. Yogurt is also a complete protein, which means it has all nine essential amino acids that your body needs to function properly (but can’t make on its own). And, most famously, it has calcium to keep your bones happy and healthy.
Bananas: Most everyone knows that bananas are a great source of potassium, but there’s so much more to this zany-looking fruit than popular knowledge conveys. Bananas also have magnesium and vitamin B6, which help regulate blood pressure and metabolism. And they have fiber to keep your gut working properly.
Flaxseed: This little seed really is worth the hype. Flaxseed is a source of omega-3 fatty acids (omega-3s, for short), which are vital for your body to function as it should. Flaxseed also has fiber and antioxidants that fight damaging free radicals and chronic inflammation.
Chia seeds: Another tiny seed with plenty of perks, chia seeds improve your digestion and promote the growth of good bacteria that keep your gut healthy. Their quirky ability to expand in fluid can help you stay fuller for longer when they’re in your stomach juices, which can be helpful if you’re trying to lose weight.
Pomegranate seeds: These little gems are as good for you as they taste. The squishy packets around the seeds contain juice that’s high in antioxidants, which might support the health of your heart. Pomegranate juice may also have cancer-fighting abilities, but research is ongoing. Still, incorporating pomegranates into a hearty, nutritious diet wouldn’t hurt!

Protect and build muscle while getting essential amino acids and calcium with this protein
Milk really does do a body good. It’s high in calcium, vitamin D and potassium. And it’s also rich in a beneficial protein called casein (pronounced ”KAY-seen“).
If you’re a regular dairy milk drinker, you’re already getting some benefits of casein. But you may want to consider adding more casein to your diet. Athletes and bodybuilders have been using casein protein powder for years. But the benefits of casein aren’t just for pro sports players.
“Protein is a vital part of any balanced diet,” says registered dietitian Elyse Homan, RD, LD. “But different proteins have different effects. Understanding how each protein works is beneficial, especially if you’re supplementing with it.”
What is casein?
Casein is the main protein found in dairy milk, which includes the milk from:
Cows.
Goats.
Sheep.
Casein makes up about 80% of the protein found in milk. The other 20% comes from whey protein.
“When you think of curds and whey,” Homan says, “the solid part is casein protein, and the liquid part is whey protein.”
Help your tissues and organs change and grow as needed.
Protect your body from viruses and bacteria.
Support your body’s movement by providing cell structure.
Casein vs. whey
Casein and whey have a lot in common. They’re both:
Animal-based proteins.
Complete proteins — they contain all the amino acids your body needs.
Excellent sources of calcium.
Found in dairy milk.
The main difference is that casein is a slower-digesting protein than whey. “Casein forms a gel-like substance in your stomach,” Homan explains. “It releases more slowly than other proteins and takes longer for your body to absorb.”
Casein protein benefits
Getting the recommended daily amount of protein helps you stay healthy. But casein’s slow absorption also gives it some added advantages. The health benefits of casein include:
1. Gives you all the essential amino acids
Amino acids combine to form proteins. There are 20 amino acids that your body needs to work correctly, and they join in various ways to create different proteins.
Your body makes some of the amino acids it needs, but there are nine essential amino acids that your body can’t produce — you must get them from food. Casein is a complete protein and has all nine essential amino acids.
2. Reduces muscle breakdown
Your cells rely on regular “feedings” of amino acids to continually make proteins. When you go without eating overnight or during an extended fast, your cells may not get the needed amino acids. As a result, they look for those amino acids elsewhere and break down your body’s muscles to get them.
As a slow-release protein, casein provides your cells with the amino acids they need over a long period. The slow absorption consistently feeds your cells with amino acids, allowing muscles to recover instead of breaking down.
3. Promotes muscle growth
Casein contains a high amount of leucine, an amino acid that regulates metabolism (how your body changes food into energy) and helps build and repair muscles. If you don’t typically consume a lot of protein, adding more leucine-heavy protein to your diet (like casein) can help your muscles grow when also engaging in regular exercise.
4. Provides a good source of calcium
The casein in milk is a good source of calcium, which is essential for teeth and bone health. Not getting enough calcium can lead to a loss of bone mass and increase your risk of osteoporosis (a disease that weakens your bones).
Casein protein powder may contain up to 50% of your recommended calcium intake — but always check the label to make sure that the protein powder is a good source of calcium.
How casein protein powder can help
Casein protein’s general health benefits are good for everyone. But using casein protein powder ensures you’ll get a more significant amount of casein each day. Talk to your healthcare provider about taking casein protein powder for:
Different types of proteins affect you differently after you eat them:
Whey protein, which you absorb quickly, makes you feel full immediately after ingesting it.
Casein’s slow rate of release helps you feel fuller longer.
One study found that participants who consumed casein protein powder before a meal ate less at that meal than people who had whey protein, egg albumin (made from egg whites) or water alone.
“Our bodies only absorb so much protein at one time,” Homan clarifies. “About 30 grams of protein per meal is a good amount to consume. If you plan to have more than one serving of casein powder daily, space it out.” It may help you stave off cravings and decrease snacking between meals, too.
Overnight muscle growth and recovery
Bodybuilders and athletes know that protein is key for building muscle. But keeping your body’s protein levels up overnight can be challenging. That is, unless you ingest casein immediately before going to sleep.
Research shows that consuming casein protein before bed balances your body’s protein level throughout the night. When your protein level stays consistent, muscles can continue to grow and recover — even though you’re not eating.
What to consider before taking casein
For most people, casein doesn’t cause any side effects. But Homan says certain people may need to avoid or limit casein if they have a condition such as:
Casein allergy
If you have a milk allergy, the proteins in milk trigger your immune system and cause it to overreact. People with a milk allergy are allergic to casein, whey or both.
A severe allergy can cause anaphylaxis. More mild symptoms of a milk allergy include:
“Casein allergies are not as common in adults as in children, but they do exist,” notes Homan. If you suspect you have a milk allergy, an allergist can do a test to figure out what you’re allergic to.
Lactose intolerance
Like all dairy products, casein contains the sugar lactose. If you have lactose intolerance, your small intestine can’t digest milk sugar. When you have dairy products, you may develop symptoms including:
“Casein supplements do have lower amounts of lactose,” Homan states. “If you’d like to include casein in your diet but have a lactose sensitivity, the supplement might not trigger it. Talk to your healthcare provider if you’re interested in taking a supplement.”
Protein restrictions
People with kidney disease often need to limit their protein. Too much protein can cause too much waste in your blood. If your kidneys can’t remove the waste, the buildup of toxins can lead to serious health complications.
“People with a protein restriction, such as those with kidney disease, don’t have to avoid casein,” Homan says. “But they do need to watch how much total protein they eat. Your healthcare provider can help you figure out the right amount.”
Sources of casein protein
There are two ways you can add casein to your diet:
Casein supplements
A powdered casein supplement can help you get high amounts of it, according to Homan. The most common form of casein powder is micellar casein, or you can get a rapidly absorbing type (casein hydrolysate). One serving typically contains 24 to 27 grams of protein. Mix with water to create a protein shake, or add it to smoothies, yogurt or baked goods.
“People looking to build muscle or get more protein in their diet should talk to their healthcare provider about adding casein,” she adds. “Supplementing with casein isn’t necessary if you have a healthy, balanced diet, but it can be helpful for some people.”
The U.S. Food and Drug Administration doesn’t regulate supplements. So, it’s a good idea to look for a casein supplement that underwent third-party testing. It’s usually a sign of a higher quality product.
Casein food sources
Anyone can benefit from casein, and you and your family probably already get it from the dairy products you consume, such as:
“Adding a dairy product to your breakfast is an easy way to get some casein every day,” Homan encourages. One glass of milk has 8 grams of protein — 6.4 grams (80%) of that protein is casein. “It’s great to start your day with a good protein source.”FACEBOOK
You’re taking cough syrup and lozenges in an attempt to get some relief. But what about using honey for sore throat symptoms? Does this natural home remedy actually work to soothe a sore throat and cough?
In addition to having other symptoms like nasal congestion, fatigue and fever, you may develop a cough.
Honey has a long history of being used as a natural remedy. And one remedy is to soothe sore throats and help alleviate a cough.
“Research shows that honey has some antimicrobial and anti-inflammation properties. Honey can help by decreasing inflammation and irritation in your throat,” explains Dr. Rainbolt. “Another study shows that honey may reduce mucus secretion. So, you can use honey for cough symptoms as well, whether it’s a wet or dry cough.”
Is it safe for children?
Giving honey to a child under 1-year-old isn’t recommended, warns Dr. Rainbolt.
“There’s concern for an infant botulism, a serious illness that’s caused by Clostridium botulinum,” she continues. “While it’s a rare occurrence, honey can contain spores that cause botulism. It attacks the body’s nervous system and children under one are more vulnerable.”
How to use for a sore throat
Most sore throats tend to get better within a week, but during that time, adults can take a spoonful (about 1 teaspoon) of honey for a cough and sore throat.
You can also dilute half a teaspoon to 1 teaspoon of honey in warm water or tea. This method is also recommended for children older than 1.
“You can use it with any kind of herbal tea or warm water with lemon juice, which can be soothing as well,” says Dr. Rainbolt.
So, how often can you use this home remedy? Dr. Rainbolt recommends using honey no more than four or five times a day.
And part of that reasoning is that honey does contain sugar.
“If you’re concerned about your sugar intake, then I recommend using honey more sparingly,” she says. “I would just use it at night to give you some relief before you go to bed.”
And can you use both honey and traditional cold medicine?
Yes, says Dr. Rainbolt.
“If it seems like the honey isn’t helping on its own, then you can certainly do both honey and medication, if medicine is something that you are able to take,” she notes.
Is honey safe to use?
Honey can be a helpful tool for those who can’t take traditional cold medications — for example, children under 6 years old or individuals with health conditions like high blood pressure or cardiovascular disease.
Overall, honey can be a good way to help soothe your sore throat and cough. It doesn’t come with some of the side effects that over-the-counter medications have like drowsiness.
So, can you just buy any honey you see on the grocery store shelf?
Yes, but you might want to make sure it’s been pasteurized. The pasteurization process removes any crystallization and unwanted yeast. It also improves honey’s texture and color, while extending its shelf life.
Dr. Rainbolt also mentions that some people think using local honey, which tends to be unpasteurized or raw, can come with extra benefits.
“There’s a thought that if you use local honey, you are exposed to some of the area’s natural allergens in a positive way,” she explains. “The idea is that it will help with allergies you have.”
The next time your throat starts to tickle, reach for honey and see if it helps.
“Think of honey as a first line of defense for those over 1 year old,” says Dr. Rainbolt. “Honey is something that pretty much everyone can try. And it’s been shown to work as well as some cough suppressant medications. It’s a nice alternative.”
Registered dietitian Lara Whitson, RD, LD, shares how watermelon is actually healthy for you, along with five watermelon recipes.
Is watermelon healthy?
Watermelon is 92% water. No surprise there, considering it’s in the name. But more than keeping you hydrated during hot summer days, watermelon has a number of other health benefits. It’s packed with antioxidants like lycopene that can help protect against chronic diseases like diabetes and cardiovascular disease.
And when eaten regularly as part of a healthy balanced diet, it can help make you feel fuller longer. With a low amount of calories, sodium and cholesterol, alongside higher amounts of calcium, vitamin C and magnesium, watermelon is one fruit you don’t want to miss out on year-round. Even the rind and its seeds offer some benefits.
“You can stir-fry the rinds with other vegetables and add spices to the seeds, like you might do with pumpkin seeds, for an easy and healthful snack,” says Whitson.
Watermelon basil granita
This shaved ice dessert gets a fruity twist with watermelon chunks. It also pulls in star ingredients like fresh lime juice and basil leaves, which offer their own health benefits for a refreshing mid-afternoon sweet escape.
Watermelon, tomato and herb salad with feta
Calorie-conscious dishes can still go big on flavor. This refreshing salad, perfect for picnics and cookouts, pairs watermelon with tomatoes bountiful in benefits, alongside red wine vinegar, fresh mint, almonds and feta cheese.
Fresh watermelon fruit smoothie
This is just one of several ways to crank up your chill summer drinks: Puree 1-1 1/2 cups chopped watermelon with 1 cup ice and a little water or fresh juice for a sip-worthy smoothie as you soak in the sun.
Watermelon salad with cucumber, tomato and almonds
This recipe doubles down on the use of veggies by incorporating beefsteak tomatoes, cucumber, a fresh ear of corn and basil, along with a hearty serving of watermelon for a subtly sweet finish.
Fruit salad spring rolls
Not only is this sweet snack filling, but it also puts a dessert-like twist on classic Vietnamese and Thai spring rolls. By wrapping julienned watermelon, green apple and pineapple in spring roll wrappers made from rice paper, and creating a dipping sauce with Greek yogurt and tahini, this recipe makes for a great palate cleanser for any summer cookout.

Here’s a medical news story that combines a common habit (drinking coffee) with a common skin condition (rosacea) — and it even has a happy ending.
What is rosacea?
Rosacea is probably something you’ve seen plenty of times and didn’t know what it was — or perhaps you have it yourself. It’s that pink or red discoloration on the cheeks some people have, especially fair-haired women. Sometimes there are small bumps that may look a bit like acne. If you look closely (after asking nicely for permission, of course), you’ll see tiny blood vessels just under the surface of the skin. In more severe cases it may involve the chin, forehead, nose, ears, and other skin surfaces. It may affect the eyes, eyelids, and cause thickening of the skin over the nose.
We don’t know what causes rosacea. However, there are theories that it may be, at least in part, a genetic condition, as it can run in families. Because the immune system seems to be involved in the inflammation of rosacea, and because other autoimmune conditions (such as type 1 diabetes and multiple sclerosis) may accompany rosacea, abnormal immune function may play a role. Medications (such as topical anti-inflammatory drugs) and antibiotics can reduce redness and inflammation but there is no cure. Many people seem to be able to reduce signs of rosacea by modifying their diet to avoid foods that trigger it.
Rosacea affects more than 14 million people in the US, including some celebrities, such as Bill Clinton and the late Diana, Princess of Wales. And while it’s not dangerous, it can have a significant cosmetic impact. Caffeine, sun exposure, spicy foods, and hormonal factors are thought to be able to trigger rosacea’s development or make it worse once present. Yet, a new study challenges the connection between caffeine and rosacea.
More coffee, less rosacea?
A recent study analyzed health data from surveys provided to nearly 83,000 women over more than a decade and found that:
Those drinking four or more cups of coffee per day were significantly less likely to report a diagnosis of rosacea than those who drank little or no coffee.
Those drinking less than four cups of coffee each day were also less likely to have rosacea, though the protective effect was smaller.
Consumption of decaffeinated coffee was not linked to a lower incidence of rosacea.
Caffeine intake from other foods or beverages (such as chocolate or tea) had no impact on the likelihood of developing rosacea.
Why is this important?
These results of this study are more than just interesting observations. If other research can confirm the findings, it could lead to a better understanding of why rosacea develops in some people and not in others. Because inflammation driven by the immune system is thought to play an important role in rosacea, insights into the development of this disease could extend to advances in other autoimmune disorders. Finally, many people with rosacea (or a family history of the disease) who like coffee may avoid it because of the widespread notion that coffee will make it worse. The findings of this study suggest that’s not true.
There are always caveats
As with all research of this type, there are limitations to consider. For example, this study
only included women, most of whom were white — we’ll need additional studies of men and other ethnic groups to know if the findings extend widely.
relied on health surveys and study participants’ memories regarding past diagnoses and diet; such survey data may not always be accurate.
found a link between higher coffee consumption with lower risk of rosacea, but it cannot determine whether coffee consumption actually caused a reduction in rosacea.
The bottom line
Coffee is one of the mostly widely consumed beverages on the planet, and it’s also among the most widely studied. While it can cause problems for some people (such as heartburn, tremor, or palpitations), it’s a source of pleasure and enjoyment for millions. In addition, coffee has been linked with a number of health benefits, ranging from reductions in type 2 diabetes and liver cancer to greater longevity. From this latest research, it appears that you can add the possible prevention of rosacea to the list.

Fuel up with protein and healthy fats for breakfast!
A meal that’s heavy in sugar and starch is no way to start your day – especially if you’re following the ketogenic diet.
These recipes from functional medicine specialist Mark Hyman, MD, are a great way for anyone — keto or not — to bring real, whole, fresh foods (including non-starchy vegetables) to your plate first thing in the morning.
Here’s a medical news story that combines a common habit (drinking coffee) with a common skin condition (rosacea) — and it even has a happy ending.

Avocados are jam-packed with nutrients and vitamins and can make a delicious, nutritious addition to your diet.
Millenials may get flak for being the “avocado toast generation,” but honestly, they may be onto something! Avocados are as nutritious as they are delicious, and they’re jam-packed with vitamins and nutrients.
Avocados include vitamins C, E, K1, B6 and folate, plus essential minerals like potassium and copper. They’re low in sugar, loaded with fiber and high in monosaturated fats, aka “good” fats. Oh, and did we mention that they taste great and they’re super versatile?!
Registered dietitian Julia Zumpano, RD, LD, shares a few more good reasons to give these wrinkly green fruits a second look — plus, how to add them to your regular rotation.
Are avocados good for you?
“Avocados are a great addition to a healthy diet,” Zumpano confirms, “and there are hundreds of varieties to choose from, ranging from big to small and wrinkly to smooth.”
What they have in common: A big round pit, creamy green flesh and a whole lot of nutrients crammed into a handy, pear-shaped package.
Just don’t go overboard. Avocados are packed with nutrients, but they’re also packed with calories. A 50-gram portion — about a third of a medium-sized avocado — has about 75 calories. And an entire large avocado can add upward of 400 calories to your daily diet.
Like most things, Zumpano says, moderation is key. “As long as you’re paying attention to portion sizes, avocados are very healthy foods to include in your food repertoire.”
Benefits of avocados
Whether you’re adding a slice to a salad or sandwich or using them as an ingredient in a more complicated recipe, Zumpano says avocados have a lot going for them health-wise.
Here are some of the many nutrients and vitamins packed into just a single avocado:
High in ‘good’ fats
You might’ve heard that avocados are high in fat — and that’s true, but it doesn’t mean you should avoid them! A medium avocado has 22 grams of fat, which includes 15 grams of monounsaturated fats, aka “good” fats.
“Avocados are rich in heart-healthy monounsaturated fats, which help lower your LDL, or ‘bad’ cholesterol,” Zumpano says. “Low LDL levels reduce your risk of heart disease and stroke.”
The American Heart Association says most of the fats you eat should be monounsaturated or polyunsaturated, confirming that avocados fit the bill as part of a healthy diet.
You can even swap avocado in for less-healthy fats in your home cooking. Here are some additional ways you can add this smooth, creamy fruit to your diet.
Spread avocado on a sandwich in place of mayonnaise.
Instead of dunking veggies into dips made with cheese or sour cream, try guacamole.
Forego shredded cheese on your salad and add avocado slices instead.
In baking recipes, replace butter or oil with mashed avocado, like in these chocolatey avocado brownie bites.
“If you use avocado to replace other fats, you can enjoy the flavor and nutrients and also cut down on saturated fats,” Zumpano says.
Lots of vitamins
Let’s talk vitamins: In simple terms, avocados have a lot of them! Here are the vitamins that are most abundant in avocados and what they do for your health:
Vitamin K1, or phylloquinone, is important for blood clotting, which helps stop wounds from bleeding. It also plays a role in strengthening your bones. For most adults, the daily recommended amount of vitamin K ranges from 90 to120 micrograms. Half an avocado has about 21 mcg.
Vitamin C, aka ascorbic acid, helps keep your immune system healthy. It also plays a role in the health of your tissues, blood vessels, bones and more. Depending on your age and sex, you need anywhere from 75 to 120 milligrams of vitamin C per day; half an avocado has about 10 mg.
Vitamin E, or alpha-tocopherol, is a powerful antioxidant that prevents cell damage and helps maintain muscle function. Most adults only need 15 mg of vitamin C per day, and half an avocado will give you about 4 mg of it.
Vitamin B6, also known as pyridoxine, helps your body convert food into energy. You only need a small amount of vitamin B6 each day (just 1.2 to 2 mg, depending on your age and sex), but half an avocado has about .25 mg, putting you well on your way to that daily goal.
Folateis a B vitamin that’s important for normal cell function and tissue growth. It helps your body form red blood cells and DNA, which is especially critical when you’re pregnant (but still important if you’re not). Half an avocado has about 20% of your daily recommended amount.
Low in sugar
Though most fruits are high in natural sugars, avocados rank very low on the sweetness scale. “A whole avocado has under 1.5 grams of sugar, while one medium apple, by comparison, has about 19 grams,” Zumpano points out. (Psst: It’s important to note that not all sugars are created equal! Fruit is still super-healthy.)
High in fiber
Avocados are a good source of fiber, which is a type of carbohydrate that your body can’t break down. You need both soluble and insoluble fiber — and lucky for you, avocados have both.
“Fiber can lower cholesterol and blood sugar, keep you regular and help you feel full and satisfied after a meal,” Zumpano states. Most adults need 25 to 35 grams of fiber per day, depending on your age and sex. Half an avocado provides about 7 grams.
Packed with potassium
Surprise! “Avocados actually contain more potassium than bananas,” Zumpano reveals. Half a large avocado provides about 485 mg of potassium, while a whole banana provides about 420 mg. (Most adults need 2,600 to 3,400 mg per day.)
This essential mineral is beneficial for blood pressure control and heart health. Low blood potassium can increase your blood pressure, raise your risk of kidney stones and even pull calcium out of your bones.
Increases your copper intake
Think past pennies: Copper is actually an essential trace mineral that your body needs in order to function correctly. Most Americans don’t get enough of it in their diets, but half an avocado will get you 20% of your daily recommended amount.
“Copper helps your body metabolize iron, and it plays a role in a healthy immune system and nervous system,” Zumpano explains.
Tips for enjoying avocados
“A perfectly ripe avocado is slightly firm but not rock-hard,” Zumpano says. “If it’s not ripe but you can’t wait to eat it, store it in a paper bag on the counter until it gives a little when you squeeze it.”
A ripe-but-not-too-ripe avocado is a time-limited treasure, so dive right in and get creative with your avocado creations, or embrace the millennial method and enjoy some avocado toast.
But if you need to store it for a couple of days, just be sure to keep it in the fridge — not submerged in water, as some TikTokkers recommend. Some people call it a “food hack,” but it can easily lead to foodborne illness.
“You can even freeze avocado slices if you’re worried you won’t use them in time,” Zumpano suggests. “Then, you can easily throw them into a smoothie.”
