Vitamin C – Facts and Myths

When you are compiling a list of beneficial foods and vitamins, I’m going to guess that fruits will make your list. And when it comes to health, no vitamin is likely thought of more than vitamin C.

After all, isn’t this why we are all told, ad nauseam, to consume so much orange juice? And when we have a cold what are we told to load up on? That’s right – vitamin C.

Since this vitamin is water-soluble, you need a constant supply in your diet in order to stay healthy. But what exactly does your body and mind use vitamin C for? And what foods have large amounts of vitamin C?

Physiologic Uses

Firstly, the name vitamin C itself is interesting. The L-enantiomer form of vitamin C is what is always referred to. This is despite the fact that there is another version, the D-enantiomer form. However, this form does not appear in nature.

One of the most important functions of vitamin C is for the growth and repair of tissues in your body. This means that it is a very good vitamin to have, both when recovering from exercise, or for general, everyday health.

Vitamin C also aids in the absorption of iron, helps to lower LDL cholesterol, and helps to combat free radicals. Vitamin C has also been studied to help with endothelial dysfunction, high blood pressure, and the blood vessel changes that can sometimes occur before heart disease.

Interestingly, vitamin C has also been studied to possibly help with muscle soreness. Vitamin C has also been studied to potentially help with blood pressure, helping subjects to drop 2 mm HG in one study. Another study showed a drop of 4.5 mm Hg.

Lower vitamin C levels have also been correlated with higher waist circumference, higher BMI, and a higher percentage of body fat. Linus Pauling, Ph.D. was a big proponent of vitamin C, recommending mega doses of the vitamin for nearly every symptom and condition.

However, time has not proven him correct. Though many of us associate vitamin C with colds and illness, many studies have shown that vitamin C does not prevent colds, and may only slightly reduce the duration of colds. In fact, zinc has been shown to work much better in the latter category.

Pauling went even further to postulate that vitamin C could, in his words, cure cancer, or at least prolong survival. This claim was obviously very bold, and was tested vigorously as a result. 

In one study, Pauling showed that 100 patients who were given 10,000 mg survived 3-4x longer than patients who were not given the supplement. However, there were some study design issues, and this data cannot be trusted.

Later studies unfortunately proved that Pauling wasn’t really onto anything with his vitamin C and cancer hypothesis. This is just one of many examples showing that it is often best to not trust a super food, super nutrient, or trust claims that one specific thing can cure a disease or fix problems. A well rounded diet, plenty of sleep, exercise and trying to limit stress – these are the things you can always count on.

Neurologic Uses

Since we’ve covered the physiologic uses of vitamin C, lets now take a look at the interesting ways in which vitamin C can help with brain functioning.

To start with, vitamin C is a vital antioxidant molecule in the brain. Besides this, it also serves a variety of other important functions. It is involved in several enzyme reactions such as collagen production and catecholamine synthesis.

The highest concentrations of vitamin C are actually found in the brain. There, it has been suggested that it is involved in a variety of neurotransmitter processes.

A deficiency of vitamin C is not something you want to encounter, as can be seen in the following graphic. Inferior brain development, acceleration in the aging process, and an increased risk of stroke can all result from levels of vitamin C which are too low.

Since vitamin C has an antioxidant effect, it is easy to see why a lack of the vitamin may cause an uptick in the aging process. But how does a lack of vitamin C impede brain development and increase your risk for stroke?

There is no doubt that a lack of vitamin C impairs brain development. In one study, 30% less hippocampal neurons were found in subjects who lacked adequate amounts of vitamin C. On top of that, they also had poor memories.

Developing brains are very sensitive to even small changes in vitamin C levels, and will retain the vitamin if dietary intakes drop. Besides brain development, a study came out just one year ago which showed that a lack of vitamin C actually raises risk of stroke.

In this study, those with the highest levels of vitamin C had the best protection from having a stroke. Now, before you get too excited, it must be pointed out that there were likely other factors in play, such as alcohol consumption, exercise, dietary habits et al.

Remember, there is no one super food or vitamin that can help stop disease. It also must be pointed out that these subjects were not taking mega doses of vitamin C, like Pauling may have wanted.

Food Sources

There are many foods which contain vitamin C. Besides oranges – which hopefully you’re already aware of – papayas, bell peppers, broccoli, brussels sprouts, strawberries, pineapples, kiwifruits, cantaloupes and cauliflower are all very high in vitamin C. In fact, for a mere 30 calories, you can get ¾ of your daily vitamin C requirements from only 1 cup of cauliflower. Pretty amazing!

Besides these foods, you can also get a large amount of vitamin C from: kale, cabbage, bok choy, grapefruit, parsley, turnip greens, beet greens, collard greens, raspberries, Swiss chard, tomatoes, lemons, limes, spinach, asparagus, sweet potatoes, winter squash, blueberries, cranberries, carrots, and avocados.

I stopped there, but believe it or not, there are quite a few more foods which contain copious amounts of vitamin C. With this knowledge in hand, it does strike me as fairly odd that vitamin C is so frequently consumed in supplemental form. But from that standpoint, we must realize that many take large amounts of vitamin C, mostly due to the hypothesis put forth by Pauling.

Supplement

With all the great food sources which contain vitamin C, one must wonder why you would want to supplement. There doesn’t seem to be any need to, especially if consuming adequate amounts in the diet.

Nonetheless, the vitamin C supplement market is booming, either with standalone products, or combination products with contain B vitamins and zinc, et al.

There are many, many different forms of vitamin C available. Whether it is natural, synthetic, powder, tablet, with bioflavonoids, etc. The end result from all of these products? They all are just as effective. Any difference is marginal, and this intake should be secondary from food, regardless.

For men, 90 milligrams per day of vitamin C is all that is required. No more than that has been shown to be effective. For women, this dosage actually drops to 75 milligrams per day.

This amount for either gender should easily be obtainable from food. Acquiring more than this is both unneeded and costly. If you’re looking to help with a cold, zinc would be your best bet.

Conclusion

Were you surprised at some of the misinformation that surrounds vitamin C? We largely have Linus Pauling to thank for that, since vitamin C was his big focus.

Many are surprised to learn that vitamin C isn’t a wonderful cure-all that they can take endlessly and expect to avoid all ills. Its ability to help slow aging is highly over-regarded, and instead it is simply an important antioxidant. It cannot help slow cancer, though it is found in the brain in large amounts.

If you have a cold, I wouldn’t run for the vitamin C. I would find a large supply of zinc instead. Vitamin C is however involved in several enzyme reactions such as collagen production and catecholamine synthesis. No doubt it is important. But its importance in terms of overall health have been vastly overstated by the world at large.

Remember, there is no one super food, or vitamin, which can cure all ills, and help stop disease. A well rounded diet, plenty of sleep, exercise, and trying to limit stress are the things you can always count on.

Raw or Cooked Vegetables – Which is the Healthiest Way to Eat?

Incorporating an array of vegetables into your daily meals is a key part of going Paleo.

Since you’ve unearthed (yes, pun intended!) their benefits, you may have come across this debate: Whether veggies should be eaten raw (to retain their enzymes and nutrients) or cooked (to improve digestibility). The short answer? It depends on the vegetable.

While many vegetables are easier on digestion and offer a host of benefits in their cooked state, consuming some veggies raw is also a must – to make sure you’re getting specific nutrients that are sensitive to heat.

For instance, water-soluble nutrients (e.g., vitamin C, B, and a group of nutrients called polyphenolics) appear to be specifically vulnerable to degradation during the cooking process. Therefore, many veggies that contain them should be consumed raw 

Below, you’ll find a list of veggies – clarifying which should be eaten raw or cooked, and why. Note that this list isn’t meant to prevent you from alternating between raw and cooked veggies.

Some have compounds that are destroyed by cooking, but they also have beneficial compounds that are made available by cooking.

In the end, it’s best to have a balance of raw and cooked vegetables. Use this guide to determine how to prepare veggies for your nutrient needs.

Veggies to Cook

1. Kale

In the past few years, kale has become the king of greens. This title has led many to infuse it into endless amounts of smoothies, salads, and green juices.

While moderate raw-kale consumption is perfectly fine, there are some drawbacks in consuming too much. Specifically, raw kale contains a high concentration of goitrogens (i.e., compounds that decrease the uptake of iodine by the thyroid).

For this reason, it would be best to limit raw-kale consumption if you have a thyroid issue (such as hypothyroidism) to avoid creating an iodine imbalance. Instead, alternate raw kale with a sautéed kale salad, or add kale to soups or broths.

2. Broccoli

Broccoli is a member of the Brassica family, which also includes the aforementioned kale. Like kale, broccoli contains goitrogens, which can interfere with thyroid functions. Lightly cooking broccoli (e.g., steaming it) can help lower these compounds. Broccoli contains goitrogens, and should be steamed to help lower those compounds.

However, you shouldn’t avoid raw broccoli altogether. In fact, alternating cooked and raw broccoli may lead you to absorb more sulforaphane, a cancer-fighting compound; a study showed it was absorbed better in raw broccoli.

3. Cassava (i.e., yuca)

Even though it’s not a cruciferous veggie, cassava root contains one of the highest amounts of goitrogen. As with kale and broccoli, goitrogens can interfere with normal thyroid function – if eaten in excess. Before using it in recipes, prepare it properly by thoroughly boiling it for 25 minutes.

4. Carrots

There is a split between beneficial nutrients lost in cooking carrots, and those gained by cooking them. Recent studies have shown that cooking carrots actually aids in carotenoid absorption (think betacarotene). But it also leads to a loss of polyphenols.

Your best bet is to cook carrots, so you’ll unlock their carotenoids. Meanwhile, eat other raw foods rich in polyphenols (e.g., colorful fruits like cherries, blueberries, currants, and strawberries).

5. Tomatoes

Most people consume tomatoes because of their high levels of lycopene (i.e., the antioxidant compound that gives red fruits and veggies their vibrant color).

However, it’s difficult for the body to absorb lycopene from raw tomatoes. But on the other hand, cooking tomatoes greatly enhances their absorption.

6. Spinach

Spinach contains oxalates (i.e., chemicals that naturally occur in plant foods, which serve to “protect” plants from being eaten by predators).

While all plants have varying levels of oxalates, spinach is particularly high. So how could eating it raw too often pose a problem?

When over-consumed, oxalates bind minerals in your body; this prevents their absorption. Luckily, oxalates are reduced by cooking, and can be mitigated even further by taking magnesium and calcium supplements at mealtime.

The Best Way to Cook Vegetables

Different methods of cooking have been proven to have a significant impact on nutrient preservation – mainly when steam comes out on top.

One study found that steaming broccoli was better than boiling – to preserve flavonols, phenolics, and especially glucosinolates. Steaming is the best way to cook veggies. Boiling comes in a close second.

However, boiling is a close second to steaming. But be sure to use as little water and as short a cooking time as possible. Up to 80% of the lost nutrients end up in the cooking water.

According to studies, fried veggies retain the least amount of antioxidants.

Meanwhile, baking has mixed reviews.

Overall, it seems that water-based cooking has the least destructive effect on these beneficial compounds. Use this guide to determine how to prepare veggies for your nutrient needs.

Veggies to Eat Raw

1. Garlic

While fragrant garlic is a favorite addition to stews and stir-fry’s, it turns out that heating it destroys the beneficial, cancer-fighting compounds we praise it for. Specifically, cooking garlic deactivates alliinase (i.e, the enzyme in garlic that helps form allicin).

Allicin is the active compound in garlic, which makes it such a potent health tonic. A study shows that consuming raw garlic two or three times a week reduces the risk of developing lung cancer.

Raw garlic can be finely chopped and added to homemade salad dressings, salsa, guacamole, and hot sauce. If you’re feeling bold, you can also take it “straight” with a gulp of water. Just be careful to start with a small amount of raw garlic, as too much can irritate the digestive tract.

2. Onions

Like garlic, onions also contain the anticancer compound allicin. They also contain bioflavonoids (such as quercetin) and sulphur compounds, which provide a range of health benefits. They’ve also shown to be protective against cancer.

The bioflavonoids in onions begin to degrade under high heat (i.e., temperatures exceeding 120 degrees fahrenheit). So if you cook them, do so at a lower heat.

3. Red Peppers

Red peppers are rich in vitamin C – the vitamin most susceptible to degradation from high temperatures. If you have to cook red peppers, it’s best to keep the cooking time short by lightly grilling (or briefly sautéing) over low heat.

4. Bok Choy

Bok choy is also rich in vitamin C and phytonutrients, which can be sensitive to high temperatures. If you have to cook bok choy, try working it into a stew. Then you’ll also consume the water.

5. Watercress

Aside from being rich in lutein and zeaxanthin (i.e., potent carotenoids that support vision health), watercresses are rich in cancer-fighting compounds called glucosinolates. These phytochemicals are hydrolyzed by an enzyme called myrosinase to produce isothiocyanates (i.e., the compounds in glucosinolates that produce their anticancer effect).

Cooking deactivates the myrosinase enzyme that’s responsible for making isothiocyanates accessible – possibly interfering with their anticancer effects.

Bottom Line

Here’s the main point to remember: Just as it’s important to consume a variety of vegetables every day, it’s also important to vary the way you prepare them.

This variety will ensure that you’re not missing out on important nutrients and enzymes, and it might also encourage you to try new types of vegetables.

Give Your Gut a Break with These Easy-To-Digest Foods

Whether you’re dealing with GERD, Crohn’s disease, or indigestion, your condition can be improved by eating foods that require less digestive effort from your body.

The following foods are easy on your digestive system and are packed with nourishing ingredients too. Here’s what to eat when you’re experiencing tummy trouble – and the gas-causing foods to avoid.

Easy-to-Digest Foods

Cooked Fruits

Raw fruits contain significantly more enzymes and nutrients than cooked fruits. While that’s typically a good thing, raw foods can be harder to digest when you have a digestive issue since they require further breakdown. When eating cooked foods, you get a head start on digestion by making the food easier to break down.

Cooked fruits that are gentle on digestion include:

• Applesauce
• Bananas
• Berries
• Any fruits without skins or seeds included

When cooking fruits to increase their digestion, it’s best to peel them and cook them over low to medium heat. High heat will cause them to boil and increase their sugar content.

Most fruits can be cooked on low to medium heat for 5 to 10 minutes, or until they start to break down. Apples require longer cook time than berries, for example.

Cooked Veggies

Raw veggies are ultra-healthy for you, so why do they cause tummy aches for some people? Raw vegetables are higher in fiber content than cooked alternatives. This is partly because cooking breaks down some of the fiber found in foods, making them easier to digest.

Cooked vegetables are milder on the digestive system. The best ones to eat are:

• Squash
• Pumpkin
• Zucchini
• Sweet potatoes
• Carrots
• Parsnips

Roasting, sautéing, and steaming are all excellent ways to prepare vegetables to make them easier on the gut.

Poultry and Seafood

Some who struggle to digest foods might have a hard time breaking down red meat but poultry, seafood, and even eggs all digest more rapidly and require fewer enzymes. This can mean less gas or intestinal pains, and less trouble processing the fattier cuts of meat.

The best easy-to-digest meats and proteins include:

• Chicken and turkey
• Eggs
• Shrimp and scallops
• Salmon, cod, trout, and tuna
• Bone broth

Activated Nuts and Seeds

While nuts and seeds (and grains, for that matter) contain anti-nutrients that can make digestion problematic for many, there’s a way to deactivate these gut-harming nutrients. 

When nuts and seeds are “activated”, aka soaked, the anti-nutrients found in the skins of these foods are broken down and rinsed away, leaving behind a more gut-friendly product.

The best nuts and seeds for soaking include:

• Almonds
• Cashews
• Hazelnuts
• Pecans
• Pumpkin seeds
• Sunflower seeds
• Macadamia nuts
• Walnuts

Foods to Avoid

If you’re feeling gassy or bloated, you should avoid foods that might make your condition worse. The following foods can be harder to break down than the average meal, especially if you have any health condition prone to worsened digestion.

Unripe Fruits

While fruits are loaded with antioxidants and vitamins, sometimes the ability to digest them is hindered when the fruit isn’t fully ripe or it contains skin. This can make it harder for the body to thoroughly digest.

Unripe fruits to avoid include:

• Bananas
• Citrus fruits
• Tomatoes
• Pineapple
• Dried or canned fruits of any kind
• Coconut

Cruciferous Vegetables

While cruciferous vegetables are rich in vitamins and minerals, they also have a sulfuric quality that can create major digestive problems, even if they are cooked.

The benefits don’t outweigh the physical downsides for some people, and they’re better avoiding vegetables like:

• Broccoli
• Cauliflower
• Cabbage
• Asparagus

Unsoaked Nuts and Seeds

Nuts and seeds contain anti-nutrients, which are proteins that are designed to protect the plants from being destroyed in the wild. But these anti-nutrients don’t automatically go away when they’re harvested for food consumption. In order to neutralize them, most nuts and seeds need to be soaked for a few hours up to a day.

Note: Grains and beans also contain anti-nutrients and can be extremely painful for some people to digest.

If you’re not soaking seeds and nuts, the following can be problematic and painful for digestion:

• Tree nuts
• Seeds
• Grains
• Beans

Fatty Meats

Saturated fat has been debunked as the cause of heart disease, but that doesn’t mean it’s easy for everyone to digest. It requires more enzymes and breakdown than poultry, and the higher fat content can create discomfort with gallbladder issues or other low enzyme levels.

If you’re struggling with sensitive digestion, eliminating the following might help relieve pain:

• Beef
• Lamb
• Bison
• Pork and bacon

Artificial Ingredients

Artificial sweeteners and other additives can significantly alter gut bacteria, which in turn can change the way that nutrients are able to absorb within the intestines.

Avoiding anything that isn’t a whole, natural food is an essential step toward better digestion. This would include:

• Artificial sweeteners or “zero calorie” products
• Preservatives and additives
• Food dyes and colorings

Sugar

Sugar is often the most difficult food item to quit, but most people don’t tie it to their digestive discomfort. It’s especially problematic when it comes to chronic diarrhea or intestinal cramping.

Even Paleo forms of sugar can result in digestive problems, so it’s best to avoid the following if you have gut issues:

• White sugar
• Coconut sugar
• Honey
• Maple syrup
• Stevia

The Bottom Line

While it might feel like you’re on a restrictive diet if you have to focus on easy-to-digest foods, the benefits far outweigh the momentary sacrifice.

Choosing to eat foods that help relieve the burden of the digestive system can go a long way in improving quality of life and getting your digestive problems into remission. A diet that helps ease digestive discomfort may change over time. 

Note: For some people, the foods that are hardest to break down might be easy for other people, and vice versa. Learning to pay attention to the cues that your digestive system gives you is key to successfully addressing your digestive health.
