Popeye may have been on to something with all that spinach malarkey.
A team at Rutgers University extracted liquid phytoecdysteroids from spinach and placed it on samples of cultured human muscle. According to the New Scientist, the extract “sped up [muscle] growth by 20 per cent. Rats were also slightly stronger after a month of injections of the extract…Unfortunately, you would need to eat more than a kilogram of spinach every day to gain equivalent amounts of the steroid.”
That’s something like 35 cups of raw spinach, or 6 cups of steamed spinach – impossible for even the most determined body builder. Any bets on how long it will take for GNC to bottle spinach extract and sell it as an all-natural muscle-booster? Wanna-be muscle-heads: guard your wallets!!!
