RESEARCH UPDATE: Examining the Link Between Almonds and Healthy Habits
People are always looking for the best tips for maintaining a healthy body weight and being in top health – without overhauling their entire lives. Recent research by King’s College in London looked at the link between British almond eaters and their nutrient intakes, as well as some health measures.1
This UK research is actually the second analysis of population-based survey data showing that almond intake is associated with higher diet quality scores. The first study looked at US participants using data from the National Health and Examination Survey (NHANES) and found similar connections between almond intake – usual intake of about an ounce of almond in the course of a day – in diet quality scores and other health measures2. Specific highlights from this NHANES analysis included:
- Almond eaters who typically consumed an average of an ounce of almonds per day were more likely to be physically active and less likely to smoke, suggesting that eating almonds is associated with healthier lifestyle patterns.
- Consumption of almonds was associated with higher intake of several nutrients identified as nutrients of public health concern, including dietary fiber. Almond consumers had higher intakes of other “shortfall nutrients” including vitamins A, D, E, and C; folate; and magnesium versus non-consumers.
- Almond eaters had other healthy dietary habits including consuming less total sugar, less added sugar and less saturated fat.
- Body mass index (BMI) and waist circumference were both lower in almond eaters than non-almond eaters.
Researchers used data from the National Health and Nutrition Examination Survey (NHANES; 2001-2010) to look at the association between almond consumption and dietary adequacy and diet quality of American adults, along with other lifestyle components. Adults ages 19 years and older (n = 24,808) from across the United States were included. Almond consumers (n=395) were defined as those who reported consuming almonds or almond butter during at least one of their two 24-hour diet recalls.
The diet quality element of the research was determined by using the USDA-developed Healthy Eating Index (HEI)-2010 score (100 points is a top score) and component scores. The HEI-2010 total score was about 15 points higher in almond consumers than non-consumers. Nearly all diet component scores were better in almond consumers. Interestingly, almond consumers had higher HEI scores for high-fiber foods, total vegetables, greens and beans, and total/whole fruit.
This study suggests that almond consumers may have healthier overall lifestyle components than non-consumers, and that regular consumption of almonds should be encouraged as part of a healthy dietary pattern. Currently, less than 2% of U.S. adults regularly eats almonds, which represents a large percentage of the population that might benefit from replacing empty-calorie snacks with almonds. The healthier habits associated with those who eat almonds may inspire wellness seekers to try this healthy grab-n-go snack.
Although eating almonds may not necessarily be the cause of these healthier lifestyle factors, there is something about the portfolio of healthier habits associated with people who choose almonds. Study limitations also include the reliance on self-reported dietary intake collected during 24-hour dietary recalls, as well as the possibility that almond consumers were misclassified, and there is a potential for residual confounding.
The unique nutrient package in almonds provides 160 calories with 6 grams of plant protein, 4 grams of filling dietary fiber, 13 grams of unsaturated fats, 50% of the Daily Value for vitamin E and 20% of the Daily Value for magnesium in each one ounce healthy handful.
