7 Foods That Will Taste Better Now Than They Will All Year

When you take a trip to your local grocery store, it’s easy to take the displays of fresh produce for granted – along with the fact that out-of-season produce is available virtually year-round. Pineapples in the Midwest in the middle of winter? Green beans in February?

No problem, if you live near a supermarket. Yet, there’s something to be said for choosing your produce seasonally. That is, focusing your meals around the foods that are naturally at their peak of ripeness.

Eating Seasonally Tastes Good and Is Good for You

According to the ancient science of Ayurveda, seasonal eating helps with digestion, because it favors easier-to-digest foods in the winter when your body is hard at work burning energy to keep you warm (and therefore theoretically has less energy to devote to digestion).

Seasonal produce will be fresher, too, which means its nutrients won’t have time to degrade like the same food left to sit in cold storage for days or weeks. One study found that in-season broccoli (fall) contained nearly twice as much vitamin C as out-of-season (spring) broccoli.1

The seasonality of the broccoli had an even bigger impact on vitamin C levels than whether it was organically or conventionally grown. When you eat seasonally, you’re also supporting the environment and your local community, because to get in-season foods you often have to shop locally.

In 2010, thousands of chefs voted cooking with seasonal locally grown produce as the top food trend … but there’s nothing “trendy” about it. People have been eating seasonally since the beginning. As the Cleveland Clinic put it:2

“Eating foods when nature produces them is what people the world over have done naturally through most of history, before mega-supermarkets dotted the landscape and processed foods became ubiquitous.

Seasonal eating is also a cornerstone of several ancient and holistic medical traditions, which view it as integral to good health and emotional balance.”

7 Foods That Taste Best in Winter

Perhaps best of all, seasonal produce will be at its peak in flavor, too, even if it’s in the middle of winter. Many winter-season vegetables taste better after a frost. This is because as temperatures drop, the cold causes the plants to break down energy stores into sugar, leading to a sweeter, tastier flavor.3

With that in mind, the seven foods that follow taste best in the winter, making them ideal to add to your seasonal shopping list.

1. Kale

One cup of kale contains just around 30 calories but will provide you with seven times the daily recommended amount of vitamin K1, twice the amount of vitamin A and a day’s worth of vitamin C, plus antioxidants, minerals, and much more.

This leafy green also has anti-inflammatory properties that may help prevent arthritis, heart disease, and autoimmune diseases – plant-based omega-3 fats for building cell membranes, cancer-fighting sulforaphane and indole-3-carbinol, and an impressive number of beneficial flavonoids.

Kale has a 3:1 carbohydrate-to-protein ratio – an exceptionally high amount of protein for any vegetable, and one reason why it has recently been acclaimed as the “new beef.

Surprisingly, like meat, kale contains all nine essential amino acids needed to form the proteins within your body: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine – plus, nine other non-essential ones for a total of 18.

Kale’s sometimes-bitter flavor becomes sweeter in winter and, impressively, kale can survive temperatures as low as 10 degrees F.4

2. Brussels Sprouts

Like kale, Brussels sprouts become sweeter in winter, so if you think you don’t like them, try them again now. One cup of cooked Brussels sprouts contains just 56 calories but is packed with more than 240 percent of the recommended daily amount (RDA) for vitamin K1, and nearly 130 percent of the RDA for vitamin C.

Plus, Brussels sprouts are a good source of fiber, manganese, potassium, choline, and B vitamins. They even contain protein. But not only do Brussels sprouts contain well-known antioxidants like vitamin C…

They also contain others that are much less known – but equally as important, like kaempferol, isorhamnetin, caffeic, and ferulic acids, and the relatively rare sulfur-containing compound called D3T (3H-1,2-dithiole-3-thione).

This means that when you eat Brussels sprouts, you’re helping your body to ward off chronic oxidative stress, which is a risk factor for many types of cancer and other chronic diseases.

You can steam Brussels sprouts and toss them with olive oil, Parmesan cheese, or butter. You can roast them and quarter them, then toss them like a salad with onions, feta cheese, and balsamic vinegar.

If your Brussels sprouts become overly “smelly,” mushy, or turn a muted green, they’re probably overcooked. Ideally, they should be bright green with a slightly crisp texture and pleasant, nutty/sweet flavor, even after they’re cooked.

3. Kohlrabi

Kohlrabi is German for “cabbage turnip,” which is actually a spot-on way to describe this vegetable’s flavor. This is a great plant to add to your winter garden, as it thrives in cool weather. When planted several weeks before a frost, you can expect a harvest in just a few weeks.5

This root vegetable is a member of the cruciferous family of vegetables, along with such nutrition superstars as broccoli, cabbage, and Brussels sprouts.

Glucosinolates, which are sulfur-containing compounds found in kohlrabi, appear to have anti-cancer, anti-fungal, anti-parasitic, and antibacterial benefits.

Kohlrabi can be cooked as you would carrots or turnips, but it can also be eaten raw (and this may be the best way of all).  Kantha Shelke, a food scientist at Corvus Blue LLC and spokesperson for the Institute of Food Technologists (IFT), told TIME:6

“Kohlrabi’s chemopreventive effects makes it particularly healthy … Kohlrabi contains isothiocyanates which are effective against cancer. The chemopreventive compounds are more bioavailable from fresh–about three times as much as from cooked–kohlrabi.

 The higher bioavailability is associated with a higher chemopreventive activity, which might be the reason why raw kohlrabi is preferentially consumed by health-conscious people.”

4. Mustard Greens

Mustard greens have a peppery flavor that’s better after a frost, and they make a perfect warming food on a cold winter day. Notably, they are a phenomenal source of vitamin K1 (providing 922 percent of the recommended daily value in just one cup) and vitamin A (96 percent of the recommended daily value).

Mustard greens are another standout member of the cruciferous family of vegetables, with research showing they rank second only to Brussels sprouts in terms of the cancer-fighting glucosinolates they contain.  

If you’re trying to balance out your cholesterol levels, mustard greens may help, as they bind to bile acids in your digestive tract. According to the George Mateljan Foundation:7

When bile acid binding takes place, it is easier for the bile acids to be excreted from the body. Since bile acids are made from cholesterol, the net impact of this bile acid binding is a lowering of the body’s cholesterol level. It’s worth noting that steamed mustard greens (and all steamed forms of the cruciferous vegetables) show much greater bile acid binding ability than raw mustard greens.”

5. Parsnips

Parsnips are root vegetables that resemble carrots but are whitish in color and have a sweet, nutty flavor. Their flavor is best after a hard frost. Parsnips are rich in nutrients like fiber, folate, potassium, and vitamin C. Eating foods rich in potassium is important because this nutrient helps offset the hypertensive effects of sodium. An imbalance in your sodium-potassium ratio can lead to high blood pressure and may also contribute to a number of other diseases, including heart disease and stroke.

6. Collard Greens

Collard greens outshined even mustard greens in their ability to bind to bile acids in your digestive tract, which may help support healthy cholesterol levels.8 Plus, like mustard greens, they’re rich in vitamins K1 and A, along with cancer-fighting glucosinolates that support healthy detoxification and fight inflammation. Collard greens also contain a wealth of antioxidants, including not only vitamins C and A but also vitamin E, caffeic acid, ferulic acid, quercetin, and kaempferol. This will help your body to ward of chronic oxidative stress, which may contribute to chronic disease and premature aging. Like the other winter vegetables mentioned, collard greens become sweeter after a frost.

7. Cabbage

Some types of cabbage can be grown in temperatures as low as 26 degrees F.9 What is cabbage good for? Cabbage contains powerful antioxidants like vitamins A and C and phytonutrients such as thiocyanates, lutein, zeaxanthin, isothiocyanates, and sulforaphane, which stimulate detoxifying enzymes and may protect against breast, colon and prostate cancers. Cabbage also contains a wealth of anti-inflammatory nutrients to help keep inflammation in check.

Among them are anthocyanins, a type of polyphenol that’s particularly plentiful in red cabbage, although all types of cabbage contain anti-inflammatory polyphenols. Cabbage also contains healthy amounts of B vitamins, including folate (which is better than the synthetic form known as folic acid found in many supplements), vitamin B6, vitamin B1, and vitamin B5. B vitamins are not only important for energy, they may also slow brain shrinkage by as much as seven-fold in brain regions specifically known to be most impacted by Alzheimer’s disease.

Starting a Winter Garden

Many people assume that the best time to start a garden is in early spring. Depending on where you live, however, you can garden virtually year-round. Even in the northernmost areas of the US, a wide variety of vegetables can be grown during the winter, especially with the assistance of a few simple temperature-shielding strategies, such as cold frames, cloches and row covers. For your winter garden, your most important date to know is your “first frost” date. You’ll want to plant your seeds early enough that the plants will be established before getting subjected to a light freeze. So your first step is to check your hardiness zone to see when your first frost is expected.

Most winter veggies are planted in mid to late summer so they are strong and ready for when the temperatures drop, and then ripe for harvest in winter or early spring. Timing this depends on how long each plant takes to reach maturity. And, remember, some vegetables, such as those listed above, develop a better flavor after a frost, so you’ll need to plan accordingly. The following tables list the best vegetables for a winter garden and how long it takes each to mature, on average.

There are certain varieties of each veggie that are more suitable for cooler temperatures, and the seed packet often gives you this information. If not, make use of the staff’s expertise at your local nursery—they usually know what varieties perform best in your area and are usually eager to help. With a bit of planning, next winter you can be feasting on parsnips, Brussels sprouts, kohlrabi, and more, all grown right in your own backyard.

Documentary Film Explores the Enormous Price We Pay for Ignoring the Need for Sleep


Article Source: Health And Fitness Journal

By Dr. Mercola

According to the documentary, Sleepless in America, coproduced by the National Geographic Channel, 40 percent of Americans are sleep deprived. Many get less than five hours of sleep per night. Percentage-wise, adolescents are among the most sleep deprived.

The consequences are dire, not just for the individual who isn’t getting enough rest, but for those around them as well. While most people don’t give lack of sleep much thought, there are in fact life-threatening consequences.

Notably, “experts now believe that sleep deprivation may have played a role in the Exxon Valdez oil spill, the Staten Island ferry crash, and the Three-Mile Island nuclear meltdown,” the film states. Countless people have also lost their lives to tired drivers who simply dozed off behind the wheel.

It’s important to realize that getting less than six hours of sleep each night leaves you cognitively impaired. Sleep deprivation has also been linked to health effects such as obesity, diabetes, cardiovascular disease, Alzheimer’s,1 and cancer. Depression and anxiety disorders are also adversely impacted by lack of sleep.

The Importance of Staying in Sync with Nature

Maintaining a natural rhythm of exposure to sunlight during the day and darkness at night is one crucial foundational component of sleeping well.

This was addressed in a previous interview with researcher Dan Pardi. In it, he explains how exposure to bright daylight serves as the major synchronizer of your master clock—a group of cells in your brain called the suprachiasmatic nuclei (SCN).

These nuclei synchronize to the light-dark cycle of your environment when light enters your eye. You also have other biological clocks throughout your body that are synchronized to your master clock.

One reason why so many people get so little sleep, and/or such poor sleep, can be traced back to a master clock disruption. In short, most people spend their days indoors, shielded from bright daylight, and then spend their evenings in too-bright artificial light.

As a result, their body clocks get out of sync with the natural rhythm of daylight and nighttime darkness, and when that happens, restorative sleep becomes elusive.

An estimated 15 million Americans also work the night shift, and the adverse health effects of working nights are well documented. As just one example, three years of periodical night shift work can increase your risk for diabetes by 20 percent, and this risk continues to rise with time.

What Happens When You’re Sleep Deprived?

What makes sleep deprivation so detrimental is that it doesn’t just impact one aspect of your health… it impacts many. Among them are five major risks to your mental and physical well-being:

  1. Reaction time slows: When you’re sleep-deprived, you’re not going to react as quickly as you normally would, making driving or other potentially dangerous activities, like using power tools, risky. One study even found that sleepiness behind the wheel was nearly as dangerous as drinking and driving.2
  2. Your cognition suffers—both short- and long-term: A single night of sleeping only four to six hours can impact your ability to think clearly the next day. In one animal study,3 sleep deprived mice lost 25 percent of the neurons located in their locus coeruleus, a nucleus in the brainstem associated with cognitive processes.
  3. Hence, if you’re sleep-deprived you will have trouble processing information and making decisions. This is why it’s so important to get a good night’s sleep prior to important events at work or home.

    For example, research discussed in the film found that diagnostic mistakes shot up by 400 percent among doctors who had worked for 24 consecutive hours.

    Sleep deprived medical residents also reported a 73 percent increase in self-inflicted needle sticks and scalpel stabs, and when driving home from work, they had a 170 percent increased risk of having a serious motor vehicle accident.

    Research4 also suggests that people with chronic sleep problems may develop Alzheimer’s disease sooner than those who sleep well. One of the reasons for this is because sleep is critical for brain detoxification—a process during which harmful proteins linked to Alzheimer’s are cleared out.

  4. Memory and learning declines: The process of brain growth, or neuroplasticity, is believed to underlie your brain’s capacity to control behavior, including learning and memory. However, sleep and sleep loss modify the expression of several genes and gene products that may be important for synaptic plasticity.
  5. Furthermore, certain forms of long-term potentiation, a neural process associated with the laying down of learning and memory can be elicited in sleep, suggesting synaptic connections are strengthened while you slumber.

  6. Emotions are heightened: As your reaction time and cognition slows, your emotions will be kicked into high gear. This means that arguments with co-workers or your spouse are likely, and you’re probably going to be at fault for blowing things out of proportion.
  7. The amygdala controls basic emotions like fear and anger. As discussed in the film, another area of your brain called your frontal cortex, plays a key role in the regulation of emotions, and sleep is vital for its function.

    When you’re well rested, your frontal cortex is nicely connected to your amygdala—that deep emotional center—and works almost like “a break to your emotional gas pedal.”

    Sleep deprivation causes a disconnect between these two brain centers, allowing your emotions to run amok. Sleep deprivation also plays an important role in mental illness, and tends to result in more adverse psychiatric outcomes.

  8. Immune function and health deteriorates: Sleep deprivation has the same effect on your immune system as physical stress or illness,5 which may help explain why lack of sleep is tied to an increased risk of numerous chronic diseases.
  9. For example, research shows that sleeping less than six hours per night more than triples your risk of high blood pressure, and women who get less than four hours of shut-eye per night double their chances of dying from heart disease.6

You Need Around Eight Hours of Sleep Every Night

The studies are quite clear and most experts agree, you are seriously fooling yourself if you think you can do fine on less than eight hours of sleep. But eight hours of sleep is not eight hours in bed. If you go to bed at 10 pm and get out of bed at 6 am, you might say you’ve slept for eight hours. In reality, you probably spent at least 15-30 minutes falling asleep and may have woken during the night one or more times.

With the advent of fitness-tracking devices such as Jawbone’s UP, however, we now have access to actual sleep data (and more) from wristband users. The data is quite useful on a personal level and they helped me understand that I need to start getting to sleep around 9.30 PM if I hope to get a full eight hours of sleep, which I now typically do.

Newer devices, like Jawbone’s UP3 that should be released in early 2015, can even tell you what activities led to your best sleep and what factors resulted in poor sleep. It’s also fascinating on a larger scale, as the data reveal insights into sleep patterns from around the world.

The Glorification of Sleep Deprivation

According to the 2013 International Bedroom Poll by the National Sleep Foundation,7 25 percent of Americans report having to cut down on sleep due to long workdays. On average, Americans get only 6.5 hours of sleep on weeknights, but report needing 7.25 hours in order to function optimally. As noted in a previous article in The Atlantic:8

“For some, sleep loss is a badge of honor, a sign that they don’t require the eight-hour biological reset that the rest of us softies do. Others feel that keeping up with peers requires sacrifice at the personal level—and at least in the short-term, sleep is an invisible sacrifice.”

Modern man’s penchant for equating sleep with unproductiveness (if not outright laziness) can be traced back to the heyday of Thomas Edison, who was known for working around the clock. According to the featured article:9

“Edison spent considerable amounts of his own and his staff’s energy on in publicizing the idea that success depended in no small part in staying awake to stay ahead of the technological and economic competition.”  No one… did more to frame the issue as a simple choice between productive work and unproductive rest …

Over time, children’s books and magazines began to promote this type of Edisonian asceticism… Edison encouraged all Americans to follow his lead, claiming that sleeping eight hours a night was a waste and even harmful. “There is really no reason why men should go to bed at all,” he said in 1914.”

This culture of sleep deprivation started with the invention of the light bulb, and has only gotten worse with the proliferation of light-emitting electronics, which disrupt your natural waking-sleeping cycle. The following infographic, created by BigBrandBeds.co.uk, illustrates how your electronic gadgets wreak havoc on your sleep when used before bedtime.10


The Importance of Addressing Sleep Apnea

As discussed in the film, sleep apnea is another common cause of sleep deprivation. Sleep apnea is the inability to breathe properly, or the limitation of breath or breathing, during sleep. Obstructive sleep apnea consists of the frequent collapse of the airway during sleep, making it difficult to breathe for periods lasting as long as 10 seconds. Those with a severe form of the disorder have at least 30 disruptions per hour. Not only do these breathing disruptions interfere with sleep, leaving you unusually tired the next day, it also reduces the amount of oxygen in your blood, which can impair the function of internal organs and/or exacerbate other health conditions you may have.

The condition is closely linked to metabolic health problems such as obesity and type 2 diabetes, and according to research,11 even a modest weight reduction can halt the progression of obstructive sleep apnea. Shedding excess pounds might even cure it, according to one five-year long study.12 That said, you do not have to be obese to suffer from sleep apnea. As discussed by Dr. Arthur Strauss, a dental physician and a diplomat of the American Board of Dental Sleep Medicine, factors such as the shape and size of your mouth, and the positioning of your tongue, can also play a significant role.

If your sleep apnea is related to your tongue or jaw position, specialty trained dentists can design a custom oral appliance to address the issue. These include mandibular repositioning devices, designed to shift your jaw forward, while others help hold your tongue forward without moving your jaw. Relief may also be found in the form of speech therapy treatment called oral myofunctional therapy, which helps to re-pattern your oral and facial muscles. For more information about this, please see my previous interview with Joy Moeller, who is a leading expert in this form of therapy in the US.

How to Support Your Circadian Rhythm and Sleep Better for Optimal Health

Making small adjustments to your daily routine and sleeping area can go a long way to ensure uninterrupted, restful sleep and, thereby, better health. I suggest you read through my full set of 33 healthy sleep guidelines for all of the details, but to start, consider implementing the following changes to ensure more shut-eye:

  • Avoid watching TV or using your computer in the evening, at least an hour or so before going to bed. These devices emit blue light, which tricks your brain into thinking it’s still daytime. Normally, your brain starts secreting melatonin between 9 and 10 pm, and these devices emit light that may stifle that process. You can also download a free application called F.lux13 that automatically dims your monitor or screens in the evening, which can help lessen the adverse effects if you have to use them in the evening.
  • Get some sun in the morning, and at least 30 minutes of BRIGHT sun exposure mid-day. Your circadian system needs bright light to reset itself. Ten to 15 minutes of morning sunlight will send a strong message to your internal clock that day has arrived, making it less likely to be confused by weaker light signals during the night. Also, if you work indoors, make a point to get outdoors for at least a total of 30-60 minutes during the brightest portion of the day.
  • Sleep in a dark room. Even the slightest bit of light in your bedroom can disrupt your body’s clock and your pineal gland’s melatonin production. I recommend covering your windows with drapes or blackout shades, or using an eye mask.
  • Install a low-wattage yellow, orange, or red light bulb if you need a source of light for navigation at night. Light in these bandwidths does not shut down melatonin production in the way that white and blue bandwidth light does. Salt lamps are handy for this purpose.
  • Keep the temperature in your bedroom below 70 degrees F. Many people keep their homes too warm (particularly their upstairs bedrooms). Studies show that the optimal room temperature for sleep is between 60 to 68 degrees F.
  • Take a hot bath 90 to 120 minutes before bedtime. This increases your core body temperature, and when you get out of the bath it abruptly drops, signaling your body that you are ready to sleep.
  • Avoid electromagnetic fields (EMFs) in your bedroom. EMFs can disrupt your pineal gland and its melatonin production, and may have other negative biological effects as well. A gauss meter is required if you want to measure EMF levels in various areas of your home. Ideally, you should turn off any wireless router while you are sleeping. You don’t need the Internet on while you’re asleep.
  • Use a fitness tracker to track your sleep. Chances are you’re not getting nearly as much sleep as you think, and using a fitness tracker that monitors your sleep can be a useful tool to help motivate you to get to bed earlier so you can get eight hours of sleep. When I first started using a fitness tracker, I was striving to get 8 hours of sleep, but my Jawbone UP typically recorded me at 7.5 to 7.75. Part of the equation too is going to bed earlier, as most of us have to get up at a preset time.
