What you need to know
- The CDC recommends people 65 and older and immunocompromised people receive an additional dose of the updated COVID-19 vaccine this spring—if at least four months have passed since they received a COVID-19 vaccine.
- Updated COVID-19 vaccines are effective at protecting against severe illness, hospitalization, death, and long COVID.
- The CDC also shortened the isolation period for people who are sick with COVID-19.
Last week, the CDC said people 65 and older should receive an additional dose of the updated COVID-19 vaccine this spring. The recommendation also applies to immunocompromised people, who were already eligible for an additional dose.
Older adults made up two-thirds of COVID-19-related hospitalizations between October 2023 and January 2024, so enhancing protection for this group is critical.
The CDC also shortened the isolation period for people who are sick with COVID-19, although the contagiousness of COVID-19 has not changed.
Read on to learn more about the CDC’s updated vaccination and isolation recommendations.
Who is eligible for another COVID-19 vaccine this spring?
The CDC recommends that people ages 65 and older and immunocompromised people receive an additional dose of the updated COVID-19 vaccine this spring—if at least four months have passed since they received a COVID-19 vaccine. It’s safe to receive an updated COVID-19 vaccine from Pfizer, Moderna, or Novavax, regardless of which COVID-19 vaccines you received in the past.
Updated COVID-19 vaccines are available at pharmacies, local clinics, or doctor’s offices. Visit Vaccines.gov to find an appointment near you.
Under- and uninsured adults can get the updated COVID-19 vaccine for free through the CDC’s Bridge Access Program. If you’re over 60 and unable to leave your home, call the Aging Network at 1-800-677-1116 to learn about free at-home vaccination options.
What are the benefits of staying up to date on COVID-19 vaccines?
Staying up to date on COVID-19 vaccines prevents severe illness, hospitalization, death, and long COVID.
Additionally, the CDC says staying up to date on COVID-19 vaccines is a safer and more reliable way to build protection against COVID-19 than getting sick from COVID-19.
What are the new COVID-19 isolation guidelines?
According to the CDC’s general respiratory virus guidance, people who are sick with COVID-19 or another common respiratory illness, like the flu or RSV, should isolate until they’ve been fever-free for at least 24 hours without the use of fever-reducing medication and their symptoms improve.
After that, the CDC recommends taking additional precautions for the next five days: wearing a well-fitting mask, limiting close contact with others, and improving ventilation in your home if you live with others.
If you’re sick with COVID-19, you can infect others for five to 12 days, or longer. Moderately or severely immunocompromised patients may remain infectious beyond 20 days.
For more information, talk to your health care provider.

Peas vs Green Beans – Which is Healthier?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Our Verdict
When comparing peas to green beans, we picked the peas.
Why?
Looking at macros first, peas have nearly 6x the protein, nearly 2x the fiber, and nearly 2x the carbs, making them the “more food per food” choice.
In terms of vitamins, peas have more of vitamins A, B1, B2, B3, B5, B6, B7, B9, C, and choline, while green beans have more of vitamins E and K. An easy win for peas.
In the category of minerals, peas have more copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc, while green beans have more calcium. Another overwhelming win for peas.
In short, enjoy both (diversity is good), but there’s a clear winner here and it’s peas.

Most People Who Start GLP-1 RAs Quit Them Within A Year (Here’s Why)
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Specifically, 54% quit within one year, with that number rising to 72% within two years.
We first wrote about GLP-1 receptor agonists (i.e. semaglutide drugs like Ozempic and Wegovy) a couple of years ago when popularity was just beginning to take off:
However, as we had room only to touch briefly on the side effects and what happens when you stop taking it, you might also want to check out:
What happens when I stop taking a drug like Ozempic or Mounjaro?
…and:
Notwithstanding all this information, there’s a lot of science that has still yet to be done. If you’re a regular 10almonds reader, you’ll be familiar with our research review articles—this one was more of a non-research review, i.e. looking at the great absence of evidence in certain areas, and the many cases of research simply not asking the right questions, for example:
❝Of the four studies that actually looked at the macros (unlike most studies), they found that on average, protein intake decreased by 17.1%. Which is a big deal!
It’s an especially big deal, because while protein’s obviously important for everyone, it’s especially important for anyone trying to lose weight, because muscle mass is a major factor in metabolic base rate—which in turn is much important for fat loss/maintenance than exercise, when it comes to how many calories we burn by simply existing.
A reasonable hypothesis, therefore, is that one of the numerous reasons people who quit GLP-1 agonists immediately put fat back on, is because they probably lost muscle mass in amongst their weight loss, meaning that their metabolic base rate will have decreased, meaning that they end up more disposed to put on fat than before.❞
Read in full: Semaglutide’s Surprisingly Unexamined Effects ← there are a lot more (equally concerning) items discussed in this article
Why people quit GLP-1 RAs
There was a large (n=125,474) study of US adults. The average age was about 54 years, and about 65% were female.
From the total data pool (i.e. not narrowing it down by demographic), 54% stopped within a year, and 72% within two years.
The factors most associated with discontinuation were:
- age above 65 years
- not having type 2 diabetes
The main reasons given for discontinuation were:
- High costs: self-explanatory, but it’s worth noting that people who stopped for this reason were more likely to restart later.
- Adverse side effects: the most common ones were nausea, vomiting, diarrhea, constipation, stomach pain, and loss of appetite. Rarer, but more seriously, side effects included: pancreatitis (severe abdominal pain, nausea, vomiting), gallbladder issues (gallstones, cholecystitis), kidney problems, severe allergic reactions (rash, swelling, difficulty breathing), hypoglycemia, especially if taken with insulin or other diabetes medications, changes in vision (worsening diabetic retinopathy), and an increased heart rate.
- Disappointingly little weight loss: the researchers noted that GLP-1 RA results are “heterogenous”, meaning, they differ a lot. For those for whom it didn’t work, quitting was more likely, for obvious reasons. See also: 10 Mistakes To Sabotage Your Ozempic Progress
- Successful weight loss: while it is widely known that if one stops taking GLP-1 RAs, weight regain is the usual next thing to happen, there are a lot of people who go onto GLP-1 RAs with the rationale “I’ll just use this to lose the weight, and then I’ll keep the weight off with my diet and lifestyle”. Which sounds reasonable, but because of the specific mechanisms of actions of GLP-1 RAs, it simply doesn’t work that way (and, as we mentioned above, there are reasons that you may, after stopping taking GLP-1 RAs, be more disposed to put weight on than you were before you started). So, by the best of current science (which admittedly is not amazing when it comes to this topic), it does seem that taking GLP-1 RAs is a lifetime commitment.

Pine Nuts vs Pecans – Which is Healthier?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Our Verdict
When comparing pine nuts to pecans, we picked the pine nuts.
Why?
Both have their merits!
In terms of macros, pine nuts have more protein while pecans have more fiber. They’re about equal on fats, although pine nuts have more polyunsaturated fat and pecans have more monounsaturated fat, of which, both are healthy. They’re also about equal on carbs. So really it comes down to the subjective choice between prioritizing protein and prioritizing fiber. On principle, we pick fiber, which gives the win to pecans, but your preference in this regard may differ; prioritizing the protein would give the win to pine nuts.
In the category of vitamins, pine nuts have more of vitamins B2, B3, B9, E, K, and choline, while pecans have more of vitamins A, B1, B5, B6, and C. Thus, a 6:5 marginal win for pine nuts.
Looking at the minerals, pine nuts have more copper, iron, magnesium, manganese, phosphorus, potassium, and zinc, while pecans have more calcium and selenium. An easy win for pine nuts this time.
Adding up the sections makes for a win for pine nuts, but of course, enjoy either or (preferably) both; diversity is good!

10 “Healthy” Foods That Are Often Worse Than You Think
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
“This is healthy, it’s a…” is an easy mistake to make if one doesn’t read the labels. Here are 10 tricksters to watch out for in particular!
Don’t be fooled by healthy aesthetics on the packaging…
Notwithstanding appearances and in many cases reputations, these all merit extra attention:
- Yogurt: sweetened yogurts, especially “fruit at the bottom / in the corner” types, often have 15–30g of sugar per serving. Plain Greek yogurt is a better choice, offering 15–20g of protein with no added sugar. You can always add fresh fruits or spices like sweet cinnamon for flavor without added sugar.
- Oatmeal: prepackaged oatmeal can contain 12–15 grams of added sugar per serving, similar to a glazed donut. Additionally, finely milled oats (as in “instant” oatmeal) can cause blood sugar spikes by itself, due to the loss of fiber. Better is plain oats, and if you like, you can sweeten them naturally with sweet cinnamon and/or fresh fruit for a healthier breakfast.
- Sushi: while sushi contains nutritious fish, it often has too much white rice (and in the US, sushi rice is also often cooked with sugar to “improve” the taste and help cohesion) and sugary sauces. This makes many rolls much less healthy. So if fish (the sashimi component of sushi) is your thing, then focus on that, and minimize sugar intake for a more balanced meal.
- Baked beans: store-bought baked beans can have up to 25g of added sugar per cup, similar to soda. Better to opt for plain beans and prepare them at home so that nothing is in them except what you personally put there.
- Deli meats: deli meats are convenient but often are more processed than they look, containing preservatives linked to health risks. Fresh, unprocessed meats like chicken or turkey breast are healthier and can still be cost-effective when bought in bulk.
- Fruit juices: fruit juices lack fiber (meaning their own natural sugars also become harmful, with no fiber to slow them down) and often contain added sugars too. Eating whole fruits is a much better way to get fiber, nutrients, and controlled healthy sugar intake.
- Hazelnut spread: hazelnut spreads are usually 50% added sugar and contain unhealthy oils like palm oil. So, skip those, and enjoy natural nut butters for healthier fats and proteins.
- Granola: granola is often loaded with added sugars and preservatives, so watch out for those.
- Sports drinks: sports drinks, with 20–25g of added sugar per serving, are unnecessary and unhelpful (except, perhaps, in case of emergency for correcting diabetic hypoglycemia). Stick to water or electrolyte drinks—and even in the latter case, check the labels for added sugar and excessive sodium!
- Dark chocolate: dark chocolate with 80% or more cocoa has health benefits but still typically contains a lot of added sugar. Check labels carefully!

Fight Inflammation & Protect Your Brain, With Quercetin
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Querying Quercetin
Quercetin is a flavonoid (and thus, antioxidant) pigment found in many plants. Capers, radishes, and coriander/cilantro score highly, but the list is large:
USDA Database for the Flavonoid Content of Selected Foods
Indeed,
❝Their regular consumption is associated with reduced risk of a number of chronic diseases, including cancer, cardiovascular disease (CVD) and neurodegenerative disorders❞
~ Dr. Aleksandra Kozłpwsla & Dr. Dorota Szostak-Wegierek
Read more: Flavonoids—food sources and health benefits
For this reason, quercetin is often sold/consumed as a supplement on the strength of its health-giving properties.
But what does the science say?
Quercetin and inflammation
In short, it helps:
❝500 mg per day quercetin supplementation for 8 weeks resulted in significant improvements in clinical symptoms, disease activity, hs-TNFα, and Health Assessment Questionnaire scores in women with rheumatoid athritis❞
Quercetin and blood pressure
It works, if antihypertensive (i.e., blood pressure lowering) effect is what you want/need:
❝…significant effect of quercetin supplementation in the reduction of BP, possibly limited to, or greater with dosages of >500 mg/day.❞
~ Dr. Maria-Corina Serban et al.
Quercetin and diabetes
We’re less confident to claim this one, because (almost?) all of the research so far as been in non-human animals or in vitro. As one team of researchers put it:
❝Despite the wealth of in animal research results suggesting the anti-diabetic and its complications potential of quercetin, its efficacy in diabetic human subjects is yet to be explored❞
Quercetin and neuroprotection
Research has been done into the effect of quercetin on the risk of Parkinson’s disease and Alzheimer’s disease, and they found…
❝The data indicate that quercetin is the major neuroprotective component in coffee against Parkinson’s disease and Alzheimer’s disease❞
Read more: Quercetin, not caffeine, is a major neuroprotective component in coffee
Summary
Quercetin is a wonderful flavonoid that can be enjoyed as part of one’s diet and by supplementation. In terms of its popular health claims:
- It has been found very effective for lowering inflammation
- It has a moderate blood pressure lowering effect
- It may have anti-diabetes potential, but the science is young
- It has been found to have a potent neuroprotective effect
