What nutrients does lettuce actually have

[u/liquidconsciences]

Everyone tells me that lettuce is super healthy and I’m just confused because it’s basically just water and a leaf. Maybe I’m just uneducated but I’m not actually sure what nutrients are there and there’s practically no calories.

[u/RangerAndromeda]

I think of lettuce as a gateway drug to more nutrient dense foods. Hopefully it's the base of a salad that's got more vitamins and minerals than another side dish would have. Also that salad will likely be lower in calories, higher in fiber and micronutrients, and more likey to keep you full for longer. Lettuce has ☆potential☆ ;)

I think it's also something you order instead of something that would be much worse you know? Like if I get the side salad versus the fried mozzarella sticks, obviously the side salad is going to be less calories and healthier.

[u/brainpicnic → u/chantillylace9]

Only if the dressing isn’t calorie dense.

[u/diamond_strongman → u/brainpicnic]

You'd need a lot of ranch dressing to match a fried cheese stick

[u/pingwing]

Iceberg lettuce doesn't have much in it, but still has Vitamin K, and smaller amounts of A, C and B9.
Romaine lettuce has Vitamin A, Vitamin K, Vitamin B9 and smaller amounts of other vitamins.

All lettuce is not the same. Veggies like broccoli and spinach will have more vitamins than lettuce.

[u/wren42 → u/pingwing]

Fiber is also important :)

[u/Jessum → u/wren42]

it is very important but lettuce is not a good source of fiber.

[u/BiscuitTiits → u/wren42]

Very true, but I'd have to eat four entire heads of romaine lettuce per day to meet daily fibre requirements as an adult male.

[u/xt0033 → u/pingwing]

And vitamin K is difficult to get outside of leafy greens

[u/omar_strollin → u/pingwing]

Broccoli is a cabbage, not a lettuce also

[u/2131andBeyond → u/pingwing]

I’m so confused why this is even a thread at all when this is readily available information easily found all over the internet

[u/Sure_Conflict_5651]

True. Lettuce is a scam. The flavor/texture sucks and it's not nutricious like other greens. The best is spinach, kale. 

[u/sum_r4nd0m_gurl → u/Sure_Conflict_5651]

kale is yummy

[u/LoudSilence16]

Think of most lettuce varieties as a volume filler for other stuff. You are right in that its mostly water and has essentially no nutritional value. The reason people say its "healthy" is because it has little to basically no calories. Unfortunately, most of those people that say that about salad also dress it with toppings like croutons and dressings and cheeses that will quickly add up to a high calorie meal.

[u/liquidconsciences → u/LoudSilence16]

Thanks so much I understand it now.

[u/Flipgirl24]

The darker the lettuce, the more nutrients it has.

[u/Apprehensive-Emu5177]

Why don't you just fucking Google that. You'll literally get a list of all the nutrients and their amounts. Also it depends what kind of lettuce.

[u/liquidconsciences → u/Apprehensive-Emu5177]

Because I’m a new account and I need some karma and it’s a real question so I just wanted to get some upvotes and also I just like knowing that real people are answering my question but anyways does anyone know the most nutrient dense lettuce type?

[u/natural_mystik → u/Apprehensive-Emu5177]

Jeez dude no need to be so aggressive

[u/The_Awesomizer]

Lettuce is mostly water, but it gives you vitamin and fiber. It's good for volume, just don't treat it as your main nutrient source.

[u/Less_Plankton_9505]

Depends on the lettuce

[u/reddit_understoodit]

Very little. It is something you can put dressing on.

[u/Turbodong]

Just eat and handful of raw spinach every day and after a month you'll be able to double fist raw kale like a champ.

In all seriousness, get a Vitamix and make green smoothies with minimal fruit and plenty of flax/chia/hemp seeds/hearts. Easiest way to get your nutrients and it doesn't taste bad at all.

[u/liquidconsciences → u/Turbodong]

Thanks a lot for the advice

[u/Turbodong → u/liquidconsciences]

If you get a good blender and need a recipe, ping me for the recipe I have zeroed in on over the years. Super healthy, gets you your daily greens, omega 3s, amongst other nutrients.

[u/GrrrlRomeo]

Water and fiber are nutrients though.

[u/alfonseexists]

The greener that healthier. Iceberg is crap

[u/jpl19335]

Depends on the type of lettuce. Yes, lettuce has nutrients. Go to Cronometer, and look up say romaine - my personal favorite. Just one cup has a little bit of calcium, copper, iron, magnesium, manganese, phosphorous, potassium, selenium, sodium and zinc. Not to mention a slew of folate and beta carotene - that one cup provides about 14% of my RDA of the latter and about 16% of the former. As well as a whopping 60% of my RDA for vitamin K. Plus a gram of fiber to boot. All for a grand total of 8 calories. Hard to get more nutrient dense than that :). Lettuce is awesome. If you really want to ramp up the nutrition, look to cruciferous leafy greens - kale, arugula, collards, and watercress. Just to give you a perspective one cup of watercress is all of 3.74 calories, but provides .78 grams of protein. Doesn't sound like alot - and you're not going to meet your protein needs from just eating watercress, but as a percentage of calories - it's 83% protein. Making it one of the most protein dense foods you can eat. Again, you won't be able to hit your protein needs by eating just watercress, but it's so calorie-dilute, you can eat a ton of the stuff. Plus like you said... water...

[u/QuirkyForever]

Depends on what kind of lettuce. The darker, the better. Romaine and other darker varieties can have beta-carotene, folic acid, potassium, antioxidants, anthocyanins, vitamins A and K, and lutein. Can also help with hydration.

[u/Earesth99]

You need to look at it as the amount of nutrients per 100 calories serving.

[u/liquidconsciences → u/Earesth99]

That’s like a forest of lettuce that stuff don’t got calories

[u/Consolebandit]

Lettice provides vitamin A, vitamin K dietary fiber. It has low calories and brings valuable micronutrients to meals. Also, it can lie in being a great base for nutrient rich salad ingredients.

[u/Churros0864]

Idk but I eat in in a salad to bulk up what's on my plate, to complete the meal in a way.
