Everyone is aware of what spinach did for Popeye. Well, that probably won't happen to you if you eat spinach, but a lot of other great things will.
But how much spinach is too much spinach? Or is it even possible to eat too much spinach?
Spinach is very safe to eat every day, but there can be negative side effects to your health if you're doing it wrong.
How Much Spinach Should You Eat In a Day?
By most accounts, a bowl of spinach each day – basically, one cup to two cups – is the most you should eat.
It's important to remember, though, that spinach is only one of the essential leafy greens you need to be eating each day.
What Is the Recommended Amount of Spinach to Consume Per Serving?
Though spinach is mostly water, it does have a concentration of nutrients and vitamins.

The Health Benefits of Eating Spinach
Decrease the risk of heart disease
Eating fresh spinach can help lower high blood pressure, prevent blood clots, improve blood flow, and just relieve stress from the cardiovascular system all of which lower the risk of getting heart disease.
Cancer prevention
The one thing that made spinach a hero in the first place was its amazing ability to prevent cancer. The chlorophyll found in spinach (the stuff that makes it green) is been found to be one of the most potent antioxidants in nature, and a healthy diet with spinach can prevent tumors.
Maintain eye health
Spinach is also great for your eyes. If you consume spinach, you are also consuming lutein and zeaxanthin, the two most powerful nutrients for your eyes. Spinach can even help prevent cataracts
Oxidative stress
Oxidative stress is what kills your cells, but the antioxidant concentrations in spinach have been proven to relieve this stress, thus protecting the cell structure in your body.
The Drawbacks of Eating Too Much Spinach
Kidney stones
Kidney stones are a mixture of two elements, calcium, and Oxalate. While spinach contains both, it's the oxalate (or oxalic acid) in spinach that is the villain here.
Eating spinach excessively can result in too high doses of oxalic acid in the body, which can make a person prone to kidney stones.
Blood clotting
Spinach is a very rich source of vitamin K, and too much vitamin K can have negative effects on blood thinner medications, to the point of making them ineffective.
FAQs
Is spinach better raw or cooked?
Spinach is one of the vegetables that are healthier if eaten cooked. The human body will better absorb the calcium and the iron in spinach if the spinach is cooked.
Spinach contains oxalic acid, which prevents the absorption of calcium and iron. But cooking spinach removes the oxalic acid.
How much spinach should I eat a week?
In general, the government's Dietary Guidelines for Americans state that you should eat 2 1/2 cups of total vegetables in a week.
Of that 2 1/2 cups, leafy greens should max out at 1 1/2 cups. So, if you are only eating spinach during the week, then 1 1/2 should be your max.
Research shows that only one in ten Americans consume the daily recommended fruit and vegetable servings. This is why consumers are turning to green superfood supplements for when nutritional intake is below par.
Will I lose weight if I eat spinach every day?
Spinach contains a lot of water and fiber with very few calories. The effect is that spinach helps you fill up faster and stay full longer.
It has been possible for some people to use daily intake to aid in weight loss. It's not the spinach that results in weight loss though, it's the fact you may eat less overall.
Is spinach good for your skin?
Spinach is great for your skin. Not only does spinach contain beneficial antioxidants that help to prevent cancer, but those same antioxidants also help protect the collagen in your skin. In addition, all of the nutrients that spinach contains are good for your skin. Eating spinach can work like you are cleaning your skin from the inside out.

LifeHacker Guy Greens Recommendation
Some Call This An "Extreme" Step...
Most super greens supplements are disappointing.
I learned this the hard way. After creating this blog in 2018, I spent months buying and testing all the most popular brands.
I wasn’t happy with the results so I did something you might call "extreme"....
In 2019 I created my own brand that ticks every single box of what I look for in a super greens product:
- No hidden ingredient amounts - we have full disclosure labelling, so you know EXACTLY whats inside
- Ingredient amounts that make a difference - we include the minimum effective amounts supported by research, and most of the time, MORE
- Ingredients that help immunity, boost mental clarity and shake off brain fog - making for a much more productive and happy lifestyle
No more worrying about ineffective ingredients or too low dosages. I finally have a product I KNOW does the job it’s made to do.
I use it every day and, after years of battling Chronic Fatigue Syndrome (CFS), I now have my energy (and my life!) back.
The good news? I made my brand available to the public so you can see and feel the difference for yourself.
