Spinach: A Nutrient Packed Superfood
Popeye used to eat the stuff by the can when he needed a little ‘pick me up’ against that brute Bruno. I like to grab a whole bunch whenever I make a salad. What is this awesome leafy green? None other than Spinach. Spinach is a leafy green vegetable that is packed with an incredible amount of goodness and is readily available to most American grocery shoppers. It is low on the calorie count but high on important nutrients like Vitamin K, Vitamin A, Manganese, folate, magnesium, iron, and scores of others.
Are you a proponent anti-oxidants? If so, you probably already know about spinach because researches have identified at least thirteen phytonutrient flavonoids that act as anti-oxidants and the reason why researchers have created extracts to use in studies to investigate it further.
My wife and I have been trying to eat more vegetables and thankfully two of our favorites are spinach and broccoli, another superfood. If you’re a salad eater, skip the iceberg lettuce (which is mostly water), and instead grab some field greens and throw some spinach on there. That minor change will help improve your health even more so than before and helps reduce those hunger pangs that strike.

Volumetrics is a diet plan developed by nutritionist Barbara Rolls, PhD, with one aim in mind – fill you up with food that is low in calories but high in volume (volumetrics! get it!?). She explains the Volumetrics diet in a 2000 book titled The Volumetrics Weight-Control Plan and then in 2005 with The Volumetrics Eating Plan.
First, who is Dr. Rolls? She’s a professor nutrition, the director of the Laboratory for the Study of Human Ingestive Behavior at Penn State University, and author of over 200 research articles. She’s not some random Joe Schmoe with a crazy plan and a dream of riches. Her plan is based on her empirical research and I think it has some merits.
So, how does it work? The plan revolves around the concept of energy density – that is the number of calories in a specified amount of food. The denser the food, the less of it you should eat. High density foods include cookies, chips, crackers, oils, nuts, chocolate and candy. Low densite foods include non-starch vegetables, low fat milk – stuff with a lot of water content. Vegetables are 80-95% water, so the idea is that you “fill up” on low energy density foods to quell that hunger urge.
It’s not a particularly innovative diet, in that it’s not some blockbuster straight out of left field idea; it’s stuff nutritionists have been saying this entire time. Personally, I’m going to integrate more vegetables into our meals. I’m a huge fan of broccoli and recently we learned that spinach was remarkably good for you so we’ll be having more of those in the future.
Home Grown Vegetables Taste Better
This spring and summer, my wife and I have restarted our patio garden and planted some tomatoes, hot peppers, and bell peppers. So far we’ve only harvested a handful of patio and Roma tomatoes but they’ve tasted fantastic. We did it for several reasons:
- There is entertainment value out of growing your own fruits and vegetables,
- It’s a fantastically frugal way to enjoy freshly picked items,
- It’s cheaper than driving to the store and buying (we hope!),
- You get a lot of satisfaction from being self-sustaining (to a certain extend).
I recently posted a video update on the garden’s progress recently and are eager to pick the eggplants!
There are studies that have shown that organically grown fruits and vegetables, despite being smaller and more expensive, pack more nutrition (vitamins, minerals, and other good stuff) than the conventionally grown stuff. One thing we’ve empirically learned was that the vegetables tasted better than from the store. Now, we don’t know if it’s because we can taste the love and sweat we put into caring for the little guys or if it’s because they’re actually tastier, but they are tastier. 
The Good Avocado Superfood
As a child I never had the opportunity to eat much avocado. I’m Chinese and avocado simply didn’t make its way into many, or any, of the meals my mom prepared so I wasn’t exposed to the delicious treat until much later. I think my first try was sometime in college when I tried guacamole, the delicious nacho topper made mostly of avocado. Since then, while I’m not an avocado fiend, I do enjoy its rich creamy flavor both on salads (it makes a great contrast with the crispness of bell peppers and lettuce) and guacamole.
Later on, I discovered that avocado was remarkably good for you. It’s surprisingly rich in monounsaturated fatty acids, the same good stuff that’s in olive oil. Monounsaturated fatty acids has been shown to lower the bad LDL cholesterol levels while increasing the good HDL cholesterol levels. In addition to those benefits, avocados also contain fiber, potassium, magnesium, folate, and antioxidants.
I don’t know if the creators of salsa and guacamole knew this but combining the lycopene in tomatoes and the vitamin E in avocados heightens the positive health benefits of both (especially enhancing antioxidant effects). You add in some onions and the oligosaccharides will boost the tomatoes’ lycopene benefits. Seems like eating lots of salsa and guacamole is pretty good for you.
So, if you’ve never tried avocado, give it a try. If you love the stuff, good for you because it’s good for you too!

Omega-3 vs. Omega-6 Balance
Earlier this week I wrote about why Omega-3 fatty acids are important and discovered that it’s not only important to eat Omega-3 oils but it’s important to ensure your Omega-3 and Omega-6 fatty acids are in proper balance. Both are essential but the proper ratio is necessary because both compete for the same metabolic enzymes. I’m not a Biology major but we know that Omega-3 and -6 fatty acids break down to the products we need (eicosanoids) and that process requires metabolic enzymes, if they’re both fighting for the same ingredients then we need to ensure one doesn’t “starve” out the other.
What’s the ratio healthy ratio? The healthy ratio appears to be anywhere from 1:1 (omega-6 to omega-3) to 4:1. According to JR Hibbeln in the American Journal of Clinical Nutrition, published June 2006, Western diets provide ratios of 10:1 to 30:1, which is far too much Omega-6.
The reason is because the oils we use often have a higher Omega-6 to Omega-3 ratio. Corn oil’s ratio is a staggering is 46:1. Popular new oils like Olive oil has anywhere from 3-13:1 and canola is 2:1 but both contain only a small amount.
How do you keep it in balance? Eat a diet rich in Omega-3′s and the it sounds like the Omega-6 will balance itself out. Eat lots of seafood or seeds that contain Omega-3 and everything should work out.
What Are Omega-3 Fatty Acids?
Omega-3 fatty acids are good for you, that’s something we’ve known for quite some time now, but do we know why? I didn’t until I did some research.
Why Omega-3
Omega-3 fatty acids are family of unsaturated fatty acids that your body can’t make itself and it’s an essential nutrient for your body. What exactly is the Omega-3? (warning, chemistry coming up) The three in Omega-3 refers to the fact that the first double bond exists as the third carbon-to-carbon bond in the methyl end of the carbon chain; that’s not important to know though when it comes to why Omega-3′s are important for you but I figured I’d share it anyway.
There are several Omega-3 fatty acids but the three that are the most important are:
- α-linolenic acid (ALA),
- eicosapentaenoic acid (EPA), and,
- docosahexaenoic acid (DHA).
Since your body can’t produce these essential fatty acids, you have to eat them!
What To Eat?
So, what should you be eating to get these fatty acids? ALA is found mostly in seeds such as flax and soybean. EPA and DHA sources are fish oil, such as from cod, salmon, sardins, mackerel and herrings. If you’re not a fan of fish or flax seed, you can simply buy supplements that provide these fatty acids.
Daily Recommended Values
Do you know what the daily recommended values (DV) are for everything on that nutrition label? It’s like budgeting, you don’t know if you’re doing well or doing poorly unless you have a reference point. Daily recommended values is the FDA’s way of setting reference points and it’s important to know what they are, even if it’s only at a high level.
Here are the high level numbers:
- Calories: 2,000
- Fat: 30% of calories – 65g
- Saturated fat: 10% of calories – 20g
- Carbohydrates: 60% of calories
- Protein: 10% of calories
- Fiber: 11.5g per 1,000 calories
- Sodium: 2,400 mg
- Cholesterol: 300 mg
That’s a ballpark estimate, obviously younger people who are growing will need more calories and those who are older will need less.

Low Carb Diet Is Best!
Which is best? Low carbs? Low fat? Or the Mediterranean diet chock full of healthy fats, fruits, and veggies? Turns out that conventional wisdom, where lower fat is always better, doesn’t always win out and the latest study shows that low carbs is actually the biggest winner. This was a story featured on ABCNews and one I caught on World News Tonight.
The Study: Researchers at Brigham and Women’s Hospital in Boston, MA put 322 obese subjects through one of three diets. The three were the ones just described, a low far, a low carb, and a Mediterranean diet. They had the subjects participate for two years and found that the low carb dieters lost the most weight, 12 lb., and the Mediterranean dieters scored second place with an average of 10 lb. Low fat dieters trimmed seven pounds in two years.
There’s more to it so check out the story on ABCNews.
What are Nitrates and Why Are They Bad!?
Nitrates, and nitrites like sodium nitrite, are additives. They were added processed foods, usually meats like cold cuts and hot dogs, to fight botulism. The unfortunate part is that they can form nitrosamines in our intestines once they are digested. Nitrosamines are bad because they might be carcinogenic.
Does that mean you should avoid processed foods like cold cuts and hot dogs? (or anything with nitrates or nitrites) No, because a diet rich in vitamin C will prevent nitrosamines from forming. It’s that very reason that foods with nitrites find themselves packed with lots of vitamin C derivatives such as ascorbate or sodium erythrobate.
Best Fruit Drinks for You
My wife used to drink a lot of apple juice as a child. She absolutely loved the stuff. Me? The only juice I ever drank was orange juice. Tropicana Pure Premium Orange Juice, usually with as much of that juicy fiberous pump as humanly possible. I always thought apple juice was like sugar water and my orange juice was the healthy goodness it was meant to be. Well, according to a study at UCLA, OJ ranks only 8th and Apple Juice ranked 10th in terms of antioxidant goodness. This makes sense though, they always say that the darker berries and grapes have the most antioxidant fighting power and oranges and apples are neither dark berries nor grapes!
Number one on the list is a fruit that has been gaining popularity, especially in the alcoholic beverage market, and that’s pomegranate juice. The other day we picked up a bottle of pomegranate liquor on a whim and we’ve had Pom brand pomegranate juice in our fridge a few times. Pomegranate itself is quite fun to eat, you crack it open, suck on the little pomegranates and then spit out the seeds.
For those vino lovers, red wine makes in at #2 and even MLM-favorite Açaà juice slides inot the #6 spot. I joke about the MLM-favorite status only because it’s this juice that is pushed by Mona Vie.
