Genuinely.
The amount of SCIENCE put into determining if frozen veggies are WORSE than fresh ones is staggering.
The tl;dr of them is
>frozen veggies are worse than fresh (in-season) veggies SLIGHTLY>frozen veggies are better than fresh (out-of-season) veggies EXPONENTIALLY >frozen veggies are better than fresh (in-season but far from farm) veggies SLIGHTLY The only catch with frozen veggies (as well as frozen fruit and berries, which follow the same results) is that the freezing can alter textures and flavor. From a nutritional standpoint, freezing is almost equal to or better than fresh equivalents. The reason for this is because as soon as these things are harvested, the nutritional value begins to decrease as the foodstuff begins to 'decompose'. Freezing prevents this breakdown, usually at 80% of its original nutritional value, compared to the process of picking and shipping fresh foodstuffs (picked prior to peak ripeness and then forcibly ripened after preparation, causing a dramatic spoilage as days go by in the market).
I actually even extracted vitamin C from carrots (year-round veggie) to determine if this was true before in Uni. We grew our own carrots and compared them to carrots purchased from the market, then to carrots that were sliced and frozen. Our home-grown ones (harvested at the peak of ripeness) had the highest amount of vitamin C, but frozen ones actually had only a 17% loss. Compared to the ones purchased "farm-fresh", which had a 45% loss in vitamin C, frozen was way better.
