00:01 - Everybody knows the average American diet
00:03 is not very healthy.
00:04 We sometimes call it S-A-D for sad.
00:07 - People don't realize that what we put in our mouths
00:12 is more important than anything else.
00:14 - Your dietary pattern can change your biology
00:16 in a profound way.
00:18 - Is it a game changer?
00:19 - I've tested many diets over the years
00:22 looking for the healthiest ones.
00:24 A major challenge in nutrition studies
00:26 is everyone is unique and responds differently
00:29 to the same food.
00:30 So what if we got people who are genetically the same?
00:33 - Just like us.
00:35 - Twins share the same DNA,
00:40 so we get to see if it's about your greens, not your genes.
00:43 - For the next eight weeks,
00:45 we'll be investigating the pros and cons
00:47 of a healthy diet that contains meat and dairy
00:49 versus a plant-based diet.
00:51 - All right, the diet assignment reveal.
00:54 - I can taste the kale now.

01:06 - We're at a critical point.
01:08 So many people are dying from diet-related diseases.
01:12 - The quality of our food,
01:15 it's changing in front of us rapidly.
01:18 - We're as sure processed meat causes cancer
01:20 as we are that cigarette smoke causes cancer
01:22 and plutonium causes cancer.
01:24 - You can't trust these labels.
01:26 If they got about this much room, then that's free range.
01:28 - Every time you eat a stick,
01:30 a little puff of smoke goes up in the Amazon.
01:32 - Many of the same things that promote human health
01:34 are also good for the environment.
01:36 - If you ask any human being,
01:37 do you wanna save the planet or destroy the planet?
01:38 I mean, come on, it's a no-brainer, right?
01:41 - Look at you all.
01:42 - I can see some differences just by looking at you.
01:44 - We actually saw profound changes
01:46 based on what diet they were eating.
01:48 - Those lines look very different, don't they?
01:50 - That's a huge difference.
01:51 - In just eight weeks.
01:52 - It shocked me.
01:53 - We can solve a lot of the issues that are hurting us
01:56 by just rethinking what's at the end of our fork.
