8 'healthy' foods that could actually be hurting your longevity, according to dietitians

 Oftentimes, the motivation behind making healthy choices is to live a longer, more vibrant life—and reaching for nourishing foods is a big part of this equation. “Maintaining healthy eating and lifestyle habits is prudent to support healthy aging and quality of life across the lifespan,” says Jessie Anderson MS, RD, registered dietitian.

When it comes to eating for longevity, we can’t necessarily rely on marketing schemes or food packaging claims. In fact, many purported "healthy" foods may actually be working against our goal of living longer. To identify some of the top culprits, we’ve spoken with two registered dietitians to gather all the need-to-know information on this topic and highlight eight foods that could actually be sabotaging your longevity efforts.

8 "Healthy" Foods That Could Be Sabotaging Your Longevity Goals

With this information in mind, we’ve rounded up a list of eight foods that, while seemingly healthy, could actually be endangering your longevity goals—but this doesn’t mean they have to be taken off the table all together. “I am a big advocate that food and eating should be enjoyable in order to be sustainable,” Anderson says. The best path is to enjoy the following foods in greater moderation, and in combination with nutrient-dense foods.


Flavored Yogurt

Though full of gut-healthy probiotics, flavored yogurt is not as healthy of a choice as advertised. “Flavored yogurts usually contain a lot of added sugars or artificial sweeteners,” says Meggie Connelly MS, RDN, LDN, registered dietitian. As it turns out, both types of sweeteners are problematic for our long-term health. “When consumed beyond recommendations, added sugars greatly impact our health through outcomes like undesired weight gain, obesity, heart disease, kidney disease, and liver diseases,” Anderson says. “Additionally, excessive added sugar intake has been linked to neurodegeneration resulting in cognitive decline.”

According to the American Heart Association, the daily limit for added sugar is no more than 6% of total calories, which shakes out to around 25 grams for many women and 36 grams for many men. “Sometimes these flavored yogurts almost meet these limits,” Connelly says.

Plain yogurt sweetened with fruit or a touch of honey is a better option.

Diet Soda

The initial aim of diet soda may have been well-intended as a viable way for people to consume less added sugar from soft drinks. However, what soda producers came up with may be just as detrimental. Though technically deemed safe for consumption, a 2022 study found artificial sweeteners to be associated with increased risk for heart disease. “Additionally, sugar alcohols (a type of alternative sweetener), such as sorbitol, lactitol, and mannitol, can cause poor absorption and result in gastrointestinal distress like bloat, abdominal cramping, diarrhea,” Anderson says.

Further, research has linked these many artificial sweeteners to negative impacts on the gut microbiome, a key player in a healthy immune system needed to fight off acute illness and life-threatening chronic disease.

Sparkling water infused with fruit and fresh herbs (like mint), or a low-sugar homemade lemonade are delicious alternatives.

Sports Drinks

Sports drinks have amazing built-in advertising as they’re commonly seen in the hands of elite athletes. However, these sugar and electrolyte-rich drinks are really only beneficial for this select (and very small) population. “These highly sweetened beverages are not really necessary for the average person, who may be working out for 30 minutes a day,” Connelly says. “They can be really tasty and easy to consume, but a diet high in sugar-sweetened beverages has been linked to increased mortality.”

And even sugar-free or artificially-sweetened sports drinks aren’t ideal alternatives for the everyday exerciser. “These are considered ultra processed foods, and a diet high in ultra processed foods has been linked to early death,” Connelly adds.

Coconut water is an electrolyte-rich alternative that offers all the hydrating benefits of sports drinks without the unwanted sweeteners, dyes, and other mystery additives (which lack long-term health impact research).

Reduced-Fat Peanut Butter

While research has now found the high unsaturated fat content of nuts to be very beneficial for heart (and overall) health, the low-fat diet mentality of decades past still lingers, keeping items like reduced-fat peanut butter on grocery store shelves. “Reduced-fat peanut butter may seem appealing to some consumers; however, those healthy fats are commonly replaced with simple or refined sugars, including high-fructose corn syrup to improve palatability and stability of the product,” Anderson says. Instead, opt for a low-ingredient natural nut butter to reap the heart, gut, immune, and metabolic health benefits of its unsaturated fat, protein, and fiber content.

Beef Jerky

Jerky and beef sticks have had a recent resurgence in popularity, with so many Americans trying to consume sky-high amounts of protein everyday. However, this seemingly healthy option may not help you make it into the centenarian club. “Beef sticks are considered red and processed meat options, and a diet high in red meats and processed meats has been linked to increased mortality,” Connelly says. Turkey jerky, plant-based jerky, nuts, seeds, or hard boiled eggs are all better on-the-go, high-protein snacks that skirt these concerns.

Energy or Protein Bars

Energy or protein bars are another type of quick convenience food that’s deceptively unhealthy. “Protein bars are notorious for sneaking in high loads of saturated fats, sodium, and artificial sweeteners,” Anderson says. Though at the center of some health-related debate, saturated fat has been found to increase cholesterol levels, while long-term excessive sodium intake can result in high blood pressure. Both of these conditions increase heart disease risk, a chronic illness that commonly cuts life short. Added sugars are also found in these bars, as their ultimate aim is to give you a boost of quick energy. “The best choice is to seek out protein bars with minimal ingredients,” Anderson says.

'Skinny' Alcoholic Beverages

Whether it be spiked seltzers, "skinny" boozes, or light beer, all of these better-for-you alcoholic beverages aren’t helping you live longer—in fact, they’re doing the opposite. "Even when consumed in moderate amounts, alcohol increases the risk of heart disease, liver disease, memory, and learning problems, as well as engagement in risky behaviors.” All of these effects can equate to a shorter lifespan; instead, a low-sugar mocktail is the most ideal alternative to these drinks.

Flavored Plant-Based Milk

While plant-based milks have gained popularity amongst health conscious consumers, the flavored options aren’t necessarily helping you to live a longer life. “While [fortified] plant-based milks can be a good source of nutrients like calcium, you need to watch out for added sugars in sweetened and flavored options, as they can become a sneaky way of adding sugar to your diet,” Connelly says. Unsweetened and fortified plant-based milks are much healthier options—thankfully, there are plenty to choose from in most grocery stores nationwide.

Nutrients That Could Be Sabotaging Your Longevity Goals

There are a handful of foods and nutrients to look out for when longevity is the aim. “We have good research that shows a diet high in ultra processed foods, artificial sweeteners, red meat, processed meats, excessive sodium intake, added sugar, saturated fats, hydrogenated (trans) fats, and alcohol are linked to increased mortality,” Connelly says.

This is primarily due to the inflammatory response these ingredients spark in the body—though other links do exist between them and specific diseases. “This chronic inflammation significantly increases the risk of heart disease and diabetes,” Connelly says. Many of these chronic diseases shorten lifespan and are leading causes of death in the U.S.

A diet high in these nutrients and foods also leaves little room for healthful counterparts that encourage longevity. “When a diet is high in ultra processed foods, red meat, processed meats, added sugar, saturated fats, trans fats, or alcohol, it generally lacks more of the health-promoting foods like fruits, vegetables, whole grains, nuts, seeds, and legumes,” Connelly says. “This means a person may not be getting enough fiber, vitamins, minerals, antioxidants, and phytochemicals for optimal health and disease prevention.”

Is it healthy to eat an avocado every day? Here's what a dietitian says

 Let’s be honest for a second. We live in a world where avocado toast reigns supreme. It dominates our brunch menus, stars in our favorite recipes, and practically has its own fan club on social media. But if you find yourself slicing into that creamy, green goodness every single day, you might pause and wonder: Is eating an avocado every day actually good for me?

As a dietitian, I hear this question all the time. People want to know whether their daily guacamole habit is a nutritional goldmine or a dietary misstep. The short answer? It depends on the rest of your plate, how much you’re eating, and a few other factors.

Let’s peel back the layers and take a closer look at what happens when avocados become a daily staple.

The Great Fruit Shortfall

First things first: Let’s settle a fun trivia fact. Avocados are technically a fruit. More specifically, they’re a single-seeded berry. And when we look at the eating habits of most Americans, fruit is something many people simply aren’t getting enough of.

The Centers for Disease Control and Prevention recommends that adults consume one and a half to two cups of fruit every day. Yet the vast majority of people do not hit that mark. If you struggle to get enough fruit into your diet, reaching for an avocado can be a fantastic way to help close that gap. It’s also helpful to remember that a standard serving size is about 1/3 of a medium Hass avocado.


So if adding avocado to your daily routine helps move you closer to your fruit goals, that’s a meaningful win for your overall health.

The Health Benefits Of Your Daily Avocado

There’s a very good reason avocados have earned their superfood status. They’re packed with nutrients your body loves.

Heart-Healthy Fats

Unlike most fruits, which are primarily made up of carbohydrates, avocados are rich in healthy fats. They’re loaded with monounsaturated fats, especially oleic acid. This is the same type of fat found in olive oil, and it’s well known for supporting heart health and helping manage inflammation. One study found that replacing energy from solid fats and added sugars with equivalent energy from one avocado daily may improve cardiometabolic risk factors, including reductions in non-HDL cholesterol and triglycerides.

Fiber Powerhouse And Gut Health Support

If you want to keep your digestive system happy, fiber matters—and avocados deliver. Their fiber supports healthy digestion, helps promote balanced blood sugar levels, and keeps you feeling full and satisfied long after a meal. One study found that eating one avocado daily, even without reducing overall calorie intake, increased gut microbiota diversity—an effect that was even more notable in people with lower diet quality scores. Greater diversity in the gut microbiome has been linked to improved digestion, enhanced immune function, and better overall health.

Vitamins and Minerals

Avocados are also impressively nutrient-dense. They provide vitamin K, vitamin E, vitamin C, and several B vitamins. Plus, they’re an excellent source of potassium. In fact, they contain more potassium than a banana. Potassium is an essential mineral that helps support healthy blood pressure and proper muscle function. One analysis of nationwide nutrition data found that, although not everyone eats avocados regularly, those who do tend to consume more key nutrients, including beta-cryptoxanthin, alpha-carotene, dietary fiber, and healthy fats.

Potential Downsides To Consider

While avocados are incredibly nutritious, it is possible to have too much of a good thing.

The biggest factor to keep in mind is energy density. Because avocados are rich in fat, they’re more calorie-dense than a typical piece of fruit like an apple or a handful of berries. One whole medium avocado contains around 240 calories. If your overall diet is already high in calories and dietary fats, adding a whole avocado every day could lead to consuming more energy than your body actually needs.

In addition, for people with certain medical conditions, such as kidney disease, potassium intake may need to be monitored closely. While eating an avocado a day is perfectly safe for a generally healthy person, those following specialized potassium-restricted diets should always check with their primary care physician before making it a daily habit.

Why Overall Diet Quality Wins

Here’s the most important piece of advice I can offer as a dietitian: Your overall diet matters far more than any single food.

We often want to label foods as “good” or “bad,” or rely on one super ingredient to magically fix our health, but nutrition simply doesn’t work that way. An avocado can’t outwork a diet that otherwise lacks nutrients, just as skipping your daily avocado won’t ruin a week of balanced eating.

You have to look at the full picture. If you eat avocado every day and you’re also eating plenty of lean proteins, whole grains, and other colorful produce, you’re likely in good shape. But if avocado is the only fruit or plant food you consistently rely on, you may miss out on nutrients that other foods provide.

That brings us to the golden rule of nutrition: variety matters. If you rely solely on avocados for your fruit intake, you miss out on the benefits of apples, oranges, berries, bananas, and other produce. While eating an avocado every day is generally safe and healthy for most people, it’s even better to rotate it in alongside a wide, colorful mix of fresh foods.

The Bottom Line

So, can you enjoy an avocado every day? Absolutely. For the average healthy adult, it can be a delicious, nutrient-dense habit that supports heart health, digestion, and satiety.

Just keep an eye on portion size, factor it into your overall daily intake, and don’t let your love of avocado stop you from exploring the rest of the produce aisle. Good health is built on balance, moderation, and a plate that doesn’t look exactly the same every day.
