Finally, the scientific reason behind your to-the-core love of avocado toast
Ever wondered why you just can't stop ordering certain foods? It turns out avocado toast nutrition explains the undying craving: The carbohydrate and fat combination makes your brain ecstatic, science says.
It’s Sunday morning, and you’re sitting down for an après-yoga outdoor brunch. As you scan the menu, you see delish, healthy options right and left (protein pancakes! omelettes! oats!). But despite the wealth of mouthwatering choices, you just can’t resist ordering nutrient-rich avocado toast for the 900th time.
Well, according to a recent study published in the journal Cell Metabolism, you owe your avo-topped obsession to a simple cognitive fact: Your brain just can’t get enough of the carb-and-fat combo. Yale University researcher Dana Small, PhD, recently observed 206 volunteers (average age 25) while an functional magnetic resonance imaging (fMRI) machine took photos of their brain activity as they decided how much they would spend snacks from a menu of fats (like cheese cubes), carbohydrates (like bread or candy), and options that combined the two (such as avocado toast or pizza).
Eating avocado toast, pizza, or any other carb-fat combo inspires high activity in the “reward” regions of the brain—including the dorsal striatum and mediodorsal thalamus—which leads to our borderline ecstatic response.
Unsurprisingly, people valued the carb-fat options most. “Participants [were] willing to pay more for fat plus carbohydrate compared with equally familiar, liked, and caloric fat or carbohydrate foods,” Dr. Small’s team notes.
And the fMRI scans revealed why: According to Dr. Small, eating avocado toast, pizza, or any other dish that adopts this irresistible partnership inspires high activity in the “reward” regions of the brain, which then leads to the nearly ecstatic responses in avo-smash addicts. According to the researchers, our brains have this reaction because—compared to our ancestors’ diet of plants and raw meat—we are spoiled by the large variety of food to which we now have access. “The modern food environment proffers up nutrients in doses and combinations that do not exist in nature,” they note, explaining why our brains get such a kick out of gobbling the carb-fat treats. They even compare the brain’s reaction to carb-fat combos to the same overstimulation it feels on drugs.

Dealing with a cold is the worst—stuffy nose, scratchy throat, endless sneezing fits—it’s enough to have you reaching for anything that promises relief. When over-the-counter meds don’t quite cut it, many of us turn to home remedies. While some swear by warm tea or chicken soup, a lot of folks on social media have been turning to a slightly smellier option: raw garlic. Yep, that pungent little clove has long been rumored to help fight colds. But does it really work, or is it just another home remedy hype?
We asked a dietitian and healthcare expert to break down the science behind garlic’s potential immune-boosting powers and whether it can actually help you beat a bad cold.
Some promising evidence suggests that it can: One study in particular found that participants who took a garlic supplement (180 milligrams of allicin daily for 12 weeks) had significantly fewer colds2—24 occurrences compared to 65 in the placebo group. While that is a big difference, the authors cautioned that more research is needed to back up the findings.
While these studies point to garlic’s potential, experts agree that more high-quality research is needed to confirm its effectiveness in preventing or treating colds. That said, it's still worth giving it a try (if you're not allergic, of course) to see if it helps you personally.
4 potential benefits of raw garlic
Raw garlic isn’t just a kitchen staple—it’s a little powerhouse of health perks. Here are a few potential health benefits you can reap from eating the aromatic vegetable.
1. It may boost immune health
The saying goes "an apple a day keeps the doctor away," but a clove of garlic might also have some immune-boosting benefits that rival the popular fruit. Case in point: garlic is thought to stimulate immune cells like macrophages and T- and B-cells, which help fight infection and produce antibodies, says William Li, MD, physician-scientist and author of Eat to Beat Disease. Studies have even found that aged garlic extract4 is associated with enhanced immune cell function because it helps immune cells replicate faster.
2. It may help prevent colds
Apart from helping fight off infection, some research suggests that garlic's bioactive ingredient allicin also contains antiviral properties5 that might help prevent viruses like the common cold, says Dr. Li. The same 2020 review in Trends in Food and Science Technology mentioned earlier backs this up, highlighting garlic’s potential in preventing colds and other viral infections by blocking pathogenic viruses6 from entering into host cells.

3. It may help support your heart
Apart from immune system support, garlic is also considered a heart-healthy ingredient. According to Dr. Li, eating garlic almost every day may:
Improve the lining of your blood vessels, which is crucial for cardiovascular health.
That said, not all studies agree on these benefits. While older studies found that garlic lowers cholesterol, newer research hasn't resulted in the same effect. This is important to keep in mind when treating an underlying heart condition; guidance from your healthcare provider and proper medication should remain the first line of care.
4. It may be protective against certain cancers
Research is limited, but some early evidence suggests that garlic (and other allium vegetables like onion) may have some cancer-fighting qualities—mostly due to its positive influence on immune cells. One review found that people who increased their garlic intake had a lower risk of certain gastrointestinal cancers9 such as stomach, colorectal, and esophageal cancer. However, other underlying factors, such as genetic risk, lifestyle habits, and previous cancer diagnoses can reduce this effect.
If you are concerned about your cancer risk, or already have cancer, your best option is to check in with your healthcare provider rather than relying on garlic consumption alone for prevention.
Are there side effects of raw garlic?
For most people, garlic is a safe, flavorful addition to make to any meal. But it's not without its own set of side effects, especially if you consume large amounts. Here are some potential side effects to watch for when eating raw garlic in particular, according to Dr. Li and Taub-Dix:
Digestive issues: Eating raw garlic can lead to things like heartburn, acid reflux, and diarrhea, especially if you're already prone to stomach problems.
Bad breath and body odor: Garlic’s strong aroma might linger in your mouth longer than you'd like, leading to some pretty ripe breath. It can even change the smell of your sweat, making it a little smellier than usual.
Blood thinning: In some cases, large amounts of raw garlic regularly can act like a blood thinner10, which can increase your bleeding risk overall.
Medication interactions: Garlic can interfere with drugs like blood thinners, HIV medications, and certain medicines that help control blood sugar, among others.
If you’re taking any prescription meds or supplements, check with your healthcare provider before adding garlic or garlic supplements to your routine. For most people, a clove or two in your cooking is perfectly safe and might even come with some bonus health perks, says Dr. Li.
How much garlic should you eat per day?
If you feel a cold coming on and want to give raw garlic a go, try eating one to two cloves per day, Dr. Li says. Any more than that could increase the odds of acid reflux, an upset stomach, or that signature "garlic breath," he adds.

Here are some great ways to get the most out of those two cloves, per Dr. Li and Taub-Dix:
Chop, crush, or mince the garlic to activate an enzyme called alliinase11, which transforms garlic’s natural compound, alliin, into allicin (which, as we've learned, is the real immune-boosting powerhouse).
Let it rest for 10 to 15 minutes after chopping to maximize its benefits. Think of it as garlic’s “air time” to power up.
And if raw garlic isn’t your jam, no problem. Taub-Dix suggests these gentler options:
Add crushed garlic to soups, broths, or sauces for a flavorful immune boost.
Pro tip: Cooked garlic has a milder taste and is less likely to give you "garlic breath," says Dr. Li. And if you prefer supplements? Garlic capsules and tablets are an option, but always check with your healthcare provider to avoid any drug interactions or side effects.
Other natural ways to relieve a cold
Not a garlic fan? No worries. Here are some other tried-and-true natural remedies from Dr. Li, Taub-Dix, and Johns Hopkins Medicine to help kick your cold to the curb:
1. Sip on some soup
Warm liquids like chicken soup or broth can remedy a sore throat, keep you hydrated, and even temporarily open your nasal passages due to the steam. Plus, it’s the ultimate comfort food during winter and peak cold season. You could even sip it from a mug like you would your morning coffee or tea.
2. Drink herbal tea with honey
Speaking of tea: Teas with ginger, turmeric, or honey tend to have both anti-inflammatory and antimicrobial properties. Not only will this help soothe your sore, inflamed throat and nasal passages, but also help keep you hydrated.

3. Load up on fruits and veggies
Sure, garlic can be a go-to if you sense a cold approaching, but loading up on plenty of fruits (like oranges, lemons, and berries) and veggies is just as important for maintaining optimal health. Plus, many fruits are packed with vitamin C, which can help support your immune system. Try adding citrus slices to tea for a hydration and vitamin boost.
4. Gargle with salt water
According to Johns Hopkins, gargling warm salt water can help reduce throat pain and swelling. Simply mix 1 teaspoon of salt in a mug of warm water, gargle over the sink, and spit.
5. Use a humidifier
Because dry air can irritate your throat, especially when sick, placing a humidifier in your bedroom while you sleep could help reduce your cold symptoms. If you don’t have a humidifier (like this one from LEVOIT, $30), try the at-home version, which is placing a bowl of water near a heat source—to add moisture to the air.
6. Get some rest
When you're feeling under the weather, your body needs plenty of rest to recover and heal. Try to rest as much as possible, which may include taking small naps, getting a full 7 to 9 hours of sleep per night, or staying in to recoup.
The bottom line
Garlic can be a helpful ally in fighting off a cold, but it’s not a cure-all. Recovery is all about balance—pairing healthy foods, proper hydration, and plenty of rest for the best results.
If your cold lingers beyond 10 to 14 days or your symptoms worsen, it might be time to see a healthcare provider. Keep an eye out for red flags like difficulty breathing, chest pain, high fever, dark phlegm, or severe dehydration, which may indicate a more serious issue beyond the common cold. Don’t hesitate to get medical help if needed—it’s always better to play it safe.
