Daily Almond Snack Linked to Better Executive Function, Blood Sugar, and Weight in Adults with Prediabetes

The relationship between nutrition and brain health is gaining increasing prominence in preventive medicine. Recently, research published in the Journal of Nutrition revealed that a change as simple as incorporating a daily handful of almonds into the diet can generate significant benefits in cognitive performance, metabolic health, and oxidative stress markers in adults with prediabetes [cite: Gulati S, et al. Effects of 24-Week Almond Supplementation on Executive Function and Processing Speed in Middle-Aged Asian Indians with Prediabetes: An Open-Label Randomized Controlled Trial. J Nutr. 2026; 156(5), 101484. https://doi.org/10.1016/j.tjnut.2026.101484.].

This finding is especially significant for regions facing critical public health challenges related to metabolic wellness, underscoring the need for accessible, science-backed dietary alternatives.

What Does the Study Reveal About Almonds and Prediabetes?

The clinical trial analyzed the effects of consuming almonds over 24 weeks (equivalent to 20% of daily calories, or about 32 to 42 grams per day) in middle-aged adults with prediabetes [cite: Gulati S, et al. Effects of 24-Week Almond Supplementation on Executive Function and Processing Speed in Middle-Aged Asian Indians with Prediabetes: An Open-Label Randomized Controlled Trial. J Nutr. 2026; 156(5), 101484. https://doi.org/10.1016/j.tjnut.2026.101484.]. The results demonstrated notable differences compared to the control group:

  • Cognitive Enhancement: Improvements were observed in executive function (including mental skills related to planning, working memory, multitasking, problem-solving, and decision-making) and processing speed [cite: Gulati S, et al. Effects of 24-Week Almond Supplementation on Executive Function and Processing Speed in Middle-Aged Asian Indians with Prediabetes: An Open-Label Randomized Controlled Trial. J Nutr. 2026; 156(5), 101484. https://doi.org/10.1016/j.tjnut.2026.101484.].

  • Glycemic Control: Lower fasting blood sugar levels, lower levels two hours post-meal, and improvements in HbA1c (a marker of long-term glycemic control) [cite: Gulati S, et al. Effects of 24-Week Almond Supplementation on Executive Function and Processing Speed in Middle-Aged Asian Indians with Prediabetes: An Open-Label Randomized Controlled Trial. J Nutr. 2026; 156(5), 101484. https://doi.org/10.1016/j.tjnut.2026.101484.].

  • Body Composition: Reductions in body weight (with an average weight loss of 3.3 kg), body mass index (BMI), body fat, and waist circumference by 3.1 cm [cite: Gulati S, et al. Effects of 24-Week Almond Supplementation on Executive Function and Processing Speed in Middle-Aged Asian Indians with Prediabetes: An Open-Label Randomized Controlled Trial. J Nutr. 2026; 156(5), 101484. https://doi.org/10.1016/j.tjnut.2026.101484.].

  • Lipid Profile and Inflammation: Decreases in total cholesterol and LDL ("bad") cholesterol, alongside reductions in markers of inflammation and oxidative stress while increasing protective compounds like vitamin E [cite: Gulati S, et al. Effects of 24-Week Almond Supplementation on Executive Function and Processing Speed in Middle-Aged Asian Indians with Prediabetes: An Open-Label Randomized Controlled Trial. J Nutr. 2026; 156(5), 101484. https://doi.org/10.1016/j.tjnut.2026.101484.].

  • What benefits does a daily consumption of almonds provide according to the study? It improves executive function and processing speed, lowers fasting and postprandial blood sugar, reduces body weight, and decreases inflammation in adults with prediabetes [cite: Gulati S, et al. Effects of 24-Week Almond Supplementation on Executive Function and Processing Speed in Middle-Aged Asian Indians with Prediabetes: An Open-Label Randomized Controlled Trial. J Nutr. 2026; 156(5), 101484. https://doi.org/10.1016/j.tjnut.2026.101484.].

  • How many almonds are recommended to consume daily according to the research? The study used a portion covering 20% of participants' daily calories, equivalent to an approximate range of 32 to 42 grams per day [cite: Gulati S, et al. Effects of 24-Week Almond Supplementation on Executive Function and Processing Speed in Middle-Aged Asian Indians with Prediabetes: An Open-Label Randomized Controlled Trial. J Nutr. 2026; 156(5), 101484. https://doi.org/10.1016/j.tjnut.2026.101484.].

Conclusion: Small Changes with Big Impact

Prediabetes affects hundreds of millions of people globally and increases the risk of developing type 2 diabetes and complications related to brain performance [cite: Rooney MR, et a. Global and Regional Prediabetes Prevalence: Updates for 2024 and Projections for 2050. Diabetes Care.2025 Nov 1;48(11):e142-e144. doi: 10.2337/dc25-1640., Issac TG, et al. Bitter effect of a Sweet Disease ‐ Exploring Cognitive dysfunction in Prediabetes from an Aging cohort. Alzheimers Dement. 2025 Jan 9;20(Suppl 5):e091309. doi: 10.1002/alz.091309.]. Incorporating nutrient-dense foods like almonds—a source of protein, fiber, healthy fats, magnesium, and vitamin E—stands out as an accessible, practical, and science-backed strategy to care for both metabolism and cognitive health [cite: Gulati S, et al. Effects of 24-Week Almond Supplementation on Executive Function and Processing Speed in Middle-Aged Asian Indians with Prediabetes: An Open-Label Randomized Controlled Trial. J Nutr. 2026; 156(5), 101484. https://doi.org/10.1016/j.tjnut.2026.101484.].
