I’ve long been a fan of avocados, so I was excited to dig into the real nutrition benefit of this versatile fruit when nutrition researcher and spokesperson for Avocados – Love One Today, Wendy Bazilian, DrPH, MA, RDN, came on the mindbodygreen podcast. We discussed everything from fat and fiber to food synergy, and I left even more confident in my love for avocados than I expected. But what I didn’t expect was how much the conversation would shift the way I think about the value of food altogether.
The avocado toast myth
Avocado toast became a cultural lightning rod, often a symbol that older generations used to exemplify the way millennials spent their money on wellness trends and aesthetics.
But Bazilian reframed that quickly and broke down why millennials may have actually been right to prioritize this trendy meal
When you look at what’s actually in an avocado—fiber, unsaturated fat, antioxidants, and more than 20 vitamins and minerals—the price-per-bite equation starts to look a lot more favorable. The real question, she said, isn’t what a food costs. It’s the value you’re getting for that cost
And the science on avocados isn’t a passing trend. A growing body of research points to how avocado offers heart health and weight management benefits and may play a role in blood sugar management
Fat is not the enemy
As a culture, we’ve spent decades being afraid of fat. As Bazilian was quick to point out, this made sense for the time. Fat has more calories per gram than carbs or protein, and early research linked certain fats to markers of cardiovascular risk. So, the common advice was to cut it out of diets
But what the science has now clarified is not all fat is the same. Bazilian explained that, in the 2010s, a number of studies showed that swapping unsaturated fats in some of the saturated fats in your diet lowers cardiovascular disease risk. Avocados are virtually the only fruit that contain unsaturated fats, with 6 grams per serving, one third of a medium avocado. Fat is also necessary for absorbing fat-soluble vitamins A, E, D, and K, and it contributes to satisfaction, texture, and the simple enjoyment of eating.
Then there’s the Habitual Avocado Trial (HAT Study)*, which is one of the most comprehensive studies on avocados to date. In this trial, nearly 1,000 people with elevated waist circumference at the start added a whole avocado a day to their diets for six months. The participants saw no weight gain or increase in visceral fat, which is the kind that raises heart disease risk
On top of that, their overall diet quality scores went up. As Bazilian put it, “You’re getting sort of a two for one here. You’re getting diet quality boost, no change in weight.”
Not all calories are created equal
Calories often create hesitation. Bazilian notes that calories are only part of the picture, but a food’s real value comes down to what it delivers within those calories
That is where avocados make a strong case. They bring unsaturated fats, fiber, more than 20 vitamins and minerals, and other nutrients that can support our day-to-day well-being. Instead of asking only how many calories are in a food, Bazilian encourages asking what you are getting per bite
Serving size vs. portion size
This is worth clearing up, because a lot of people—myself included—get it wrong. Serving size and portion size are not the same thing. “A serving size is a standard of measure. A portion is how much you eat,” Bazilian explained. In other words, the serving size gives you the math, while your portion is what you choose to eat based on your hunger and activity levels.
The fiber gap
Only about 6% of us meet the daily recommended fiber intake, according to the most recent statistics Bazilian cited. That leaves roughly 94% falling short on this key nutrient
That matters because fiber does more than just support our gut. It also slows digestion, helping you feel satisfied for longer. Fiber can also help lower LDL, or “bad,” cholesterol, which may help reduce the risk of heart disease
Bazilian believes intake remains lower because fiber is still abstract for a lot of people. We’ve gotten good at spotting proteining up from whole foods, we tend to chase it through supplements once we realize we’re behind.
But one-third of a medium avocado (a serving size) gives you three grams of fiber, which is more than 10% of the daily goal. Eat a whole avocado and you’re roughly a third of the way to the 25 to 35 grams recommended per day. Add whole grain toast, beans, and vegetables across the day, and that target becomes very reachable

Blood sugar & metabolic health
Bazilian pointed to a secondary analysis of the HAT trial* that looked at glycemic load, which is essentially the cumulative effect of food on blood sugar over time. Participants who ate one large avocado daily saw their overall dietary glycemic load drop by 14 points. Lower glycemic load has been associated with better blood sugar control and lower risk of type 2 diabetes and other cardiometabolic risk factors.
And this wasn’t about eating avocado in isolation. You can swap it in through muffins, pesto, granola bites, and marinades, replacing added sugars and saturated fat in everyday foods.
This versatility matters, because eating avocado doesn’t have to be limited to toast or guacamole. It can show up at breakfast, lunch, dinner, snacks and even dessert, making it an easy, sustainable way to add nutrients into meals you are already eating
Food synergy & nutrient absorption
One of my favorite parts of the conversation was when Bazilian talked about food synergy, the idea that certain foods become more valuable when eaten together
Avocados are a carotenoids, the plant compounds in foods like carrots and kale. When you add avocado to a salad with carrots, you’re not just adding flavor and creaminess. You’re increasing how much of those nutrients your body can absorb
For example, Bazilian makes a salad with walnuts, avocado, carrots, currants, kale and a vinaigrette. “The avocado once massaged into the kale sort of makes the cells break open, and the vitamin K in the kale comes out,” she explains. Then the carrots add those carotenoids, making a sort of “synergy salad,” where you get more from the whole than from any single ingredient
3 nutrition tips that move the needle
When I asked Bazilian to cut through the nutrition noise and name what actually moves the needle when it comes to our health, she landed on three things:
- Add, don’t subtract: The research on avocados is a case study in addition over restriction. Despite its fat content, eating a whole avocado a day improved diet quality scores and had no negative impact on weight. Look for opportunities to add foods that bring real nutritional value, and that you actually enjoy.
- Think in patterns, not single nutrients:We eat meals, not isolated nutrients. Bazilian’s point about food synergy applies here: certain foods work better together, and building a pattern of whole foods across the day compounds over time.
- Trust the practical science:As Bazilian put it, “the science that’s being done on these foods has real practical implications for our health. These are very tangible, real-life choices you can make on a regular basis.” The avocado research isn’t abstract. It’s real people eating real food, and the results are consistent.
The takeaway
This conversation with Bazilian reinforced something I keep coming back to: the foods that are easiest to add are often the ones with the most to offer. Avocados check every box—fiber, healthy fat, nutrient density—and the science behind them only continues to grow.

*Disclosures:
- The Avocado Nutrition Center funded this study and while findings from a single study cannot be generalized to the broader population they contribute to a growing body of research linking avocado consumption with better diet quality.
- The Avocado Nutrition Center also supported this study and although findings from one study cannot be generalized to the larger population, it supports a growing body of evidence that suggests consuming avocado may improve glycemic load.
