Beet Juice and Root Vegetable Juices — Performance Nutrition
Origin
Medicinal use of beets traces to ancient Rome — Pliny the Elder documented beetroot as a treatment for fever and constipation in Naturalis Historia (77 CE). Cold-press juicing culture emerged in California in the 1970s through Jack LaLanne's juicer infomercials and Jay Kordich's raw food movement. The performance nutrition application of beet juice was established by Andy Jones's research group at the University of Exeter in 2009, leading to the current $400M+ global beet supplement and juice market.
Description
Beetroot juice has emerged as the most scientifically validated performance nutrition beverage in the non-alcoholic category — with over 200 peer-reviewed studies confirming its role in increasing plasma nitrate, dilating blood vessels, reducing oxygen cost of exercise, and improving endurance performance by 1–3%. The active compound, dietary nitrate (NO3⁻), is converted in the body to nitric oxide through a saliva-mediated bacterial pathway, vasodilating muscles and improving oxygen efficiency. At the elite level, British Cycling's adoption of beet juice (Beet It Sport) during the 2012 London Olympics — where they won 8 gold medals — catalysed mainstream performance nutrition adoption. Root vegetable juices extend the category: carrot juice provides β-carotene and alpha-carotene (retinol precursors), ginger juice delivers gingerols with anti-inflammatory properties, turmeric juice provides curcumin (NF-κB inhibitor), and celery juice gained cultural momentum from Anthony William's Medical Medium protocols (though clinical evidence remains limited). The combined root juice category represents the intersection of ancient medicinal food traditions and modern sports science.
The Thread
Flavour Context
FOOD PAIRING: Beet juice with apple and ginger pairs with smoked salmon and cream cheese — the earthy beet bridges the smokiness, apple acid cuts fat, and ginger adds warmth (from Provenance 1000 Nordic and smoked fish dishes). Carrot-ginger juice pairs with Vietnamese pho and Japanese ramen — the warming root notes echo the broth spices. Celery juice is the canonical companion to green salads and light protein dishes.
