Aging is an inevitable part of life. That doesn't mean it's something to fear. Instead, the natural process our body and skin undergoes as we get older deserves our acknowledgment and our respect. How can you respect the aging process? One great way is to start thinking more about what you eat.
"We're actually learning that poor nutrition is just as bad for your skin as cigarette smoking," Patricia Farris, a dermatologist and author of The Sugar Detox, explained to health website Prevention.com. The reasons for this are multiple and relate to both short- and long-term effects.
Certain foods are crucial to keeping your skin hydrated while other foods can directly help protect your skin cells from damage that can lead to wrinkles.
"Every dermatologist will attest that a well-rounded diet will better support a healthy immune system," said Bobby Buka, a New York City dermatologist "and will therefore result in fewer dermatologic conditions of all types."
By eating the right foods and avoiding the wrong ones, you may not be able to turn back the hands of time, but you can certainly slow down some of the cogs.
Here are five foods that will have you looking more youthful long into your golden years:
1. Olive Oil
You've probably heard that olive oil is great for your heart, but did you know it's also super for your skin? A 2012 PLOS ONE study reflected this after analyzing the diets of 1,264 women. The study found that women who consumed more than 2 teaspoons of olive oil a day experienced "31 percent fewer signs of aging compared to people who ate less than 3.8 grams (about 1 teaspoon)." Olive oil in particular was responsible for this difference due to the fact that around "75 percent of the fat in olive oil is monounsaturated fatty acids."
If you spend a lot of time in the sun, tomatoes are your skin's best friend. Those juicy reds are rich in the antioxidant lycopene, which improves skin's natural SPF. That doesn't mean it acts as a replacement for sunscreen, but when used in combination, can work wonders for protecting you from harsh UV rays.
3. Dark Chocolate
Cocoa flavanols, plentiful in this foodstuff, are great for hydrating your skin. Lisa Drayer, author of The Beauty Diet, suggests for optimum benefits keeping to a 1-ounce portion (150 calories) of the stuff.
4. Sardines and Salmon
Oh, glorious omega-3 fatty acids! Why are they so good (and found in great quantity in these slippery suckers)? DHA, an anti-inflammatory omega-3, helps reduce outbreaks of acne and keeps skin clear.
5. Kale and Spinach
Rich in lutein and zeaxanthin—nutrients known for neutralizing free radicals caused by UV rays—kale and spinach also help provide "134 percent and 133 percent of your daily value for skin-firming vitamin C and A, respectively," according to reseach published in Clinics in Dermatology. Additionally, a Journal of Cancer study found that spinach-eaters "developed half as many skin tumors over 11 years" as those who went without, likely thanks to DNA-repairing folate.
Here are the five worst foods for your skin:
Of course, it is just as important to know which foods are bad for your skin so you can avoid them. The following five won't do your skin any favors.
Many a meal might call for a light savory sprinkle, but too much salt can take its toll. One of the more visible ways is the presence of puffy eyes. The reason has to do with the way salt causes skin to retain water. Too much salt in your diet can lead to swelling, particularly around areas where skin is thin, such as the eyes. This may not be a problem in your younger years, but as dermatologist Neal B. Schultz noted, "these effects of salt are definitely age related" becoming more visible the older you get.
Who doesn't love a delish bit of shellfish overlooking the ocean? (Well, apart from vegans, vegetarians and allergy sufferers). And so you should, but as with many things in life, such a thing should be enjoyed in moderation. Especially when it comes to your skin, which is prone to acne caused by a shellfish-rich diet. Why? Basically, this type of seafood is naturally high in iodine, which over time can lead to acne breakouts among those who are naturally prone.
Bet you saw this one coming. Turns out the old adage—too much alcohol will make you age faster—is more than just a preventative measure to get you to drink less. Like those hangovers some suffer from, the problem comes down to dehydration. Alcohol is a natural diuretic, so drinking too much can draw out the moisture from your skin, which with time can contribute to pronounced wrinkles and fine lines. Also, says Schultz (and anyone who knows about the natural blushing that happens after a few beers), alcohol triggers outbreaks of rosacea.
4. High Glycemic Foods
According to Dr. Buka, foods rich in starch should be avoided to maintain your complexion. Part of the reason has to do with blood sugar. When you eat starchy foods—which are considered high glycemic—this often leads to a spike in blood sugar, which in turn can spark a number of problems from acne to wrinkles. A 2007 Australian study showed that a low-glycemic diet reduced acne. As for wrinkles, explains Valori Treloar, dermatologist and author of The Clear Skin Diet, when you eat starch-based foods such as rice cakes, your body converts them into glucose, a natural enemy of the anti-wrinkle protein, collagen.
Speaking of which, any food that contains straight sugar will act much the same. In fact, said dermatologist Farris, "countries without diets heavy in processed sugar" tend to produce children who "go through puberty without acne." Moral of the story: Stay away from the sweet stuff.

Summer and fall are great seasons to enjoy the outdoors. But if you're already spending extra time outside because of the COVID-19 pandemic, you may be out of ideas on how to make fresh-air activities feel special. Here are a few suggestions to keep both adults and children entertained and educated in the months ahead, many of which can be done from the comfort of one's home or backyard.
The coronavirus may linger in the air in crowded indoor spaces, spreading from one person to the next, the World Health Organization acknowledged on Thursday, as The New York Times reported. The announcement came just days after 239 scientists wrote a letter urging the WHO to consider that the novel coronavirus is lingering in indoor spaces and infecting people, as EcoWatch reported.

It is undisputed that vitamin D plays a role everywhere in the body and performs important functions. A severe vitamin D deficiency, which can occur at a level of 12 nanograms per milliliter of blood or less, leads to severe and painful bone deformations known as rickets in infants and young children and osteomalacia in adults. Unfortunately, this is where the scientific consensus ends.
Where Does the Deficiency Begin?<p>Nobody knows exactly how much vitamin D a person actually needs. The question of when a deficiency starts is correspondingly controversial. However, vitamin D is becoming increasingly popular.Not only is the pseudo-scientific literature on the "sun vitamin" experiencing an upswing, but the number of published studies has also increased enormously in recent years. For example, in 2019 <a href="https://academic.oup.com/edrv/article/40/4/1109/5126915" target="_blank">a study found that</a> Vitamin D is responsible for keeping the skeleton functional and is associated with cardiovascular diseases, type 2 diabetes and various types of cancer. <br></p>
An All-Rounder<p>Vitamin D levels in the body rise and fall according to sun exposure. If sufficient UV rays reach the skin, the body is able to produce the vitamin itself. However, the human body only derives an estimated 10 to 20 percent of its daily requirement from food.</p><p>The vitamin D that we synthesize from sunlight or food is not biologically active at first. Before the kidneys can produce the biologically active form of the vitamin, known as calcitriol, and release it into the blood, some metabolic processes must take place beforehand.</p><p>In addition, many organs have receptors to which the precursor of calcitriol binds. Further, this substance is also present in blood.</p><p>From this precursor, the organs then produce calcitriol themselves, which the body then uses for countless other processes in the body. This form of vitamin D thus regulates insulin secretion, inhibits tumor growth, and promotes the formation of red blood cells as well as the survival and activity of macrophages, which are important for the <a href="https://www.mdpi.com/2072-6643/5/7/2502/htm" target="_blank">immune system.</a></p>
Low Vitamin D, Severe COVID-19 Disease?<p>A research study carried out <a href="https://www.sciencedirect.com/science/article/pii/S2352364620300067?via%3Dihub" target="_blank">at the University of Hohenheim</a> has now established a link between vitamin D deficiency, certain previous diseases, and severe cases of COVID-19.</p><p>According to the study, "there is a lot of evidence that several non-communicable diseases (high blood pressure, diabetes, cardiovascular diseases, metabolic syndrome) are associated with low vitamin D plasma levels. These comorbidities, together with the often accompanying vitamin D deficiency, increase the risk of severe COVID-19 events."</p><p>"This statement is completely correct," said Martin Fassnacht, head of endocrinology at the University Hospital of Würzburg. However, he qualifies that it is a pure association, "i.e. a mere observation that these events occur together.</p><p>Dr. Fassnacht is very critical of the hype surrounding vitamin D, but not because he denies the vitamin serves important functions. However, studies on humans have not been able to show that vitamin D has the healing powers many often propagate.</p><p>Fassnacht says, "If you take a closer look, the hopes that the administration of vitamin D has a healing effect have not been confirmed so far."</p>
Association Versus Intervention Studies<p>Many studies on the vitamin are association or observational studies. "By definition, these studies cannot prove the causal relationship, but only point to mere correlations," said Fassnacht. The physician tries to illustrate this with an example:</p><p>"Imagine two groups of 80-year-olds. One group is spry, active and does sports. If you compare them with another group living in nursing homes, the difference in vitamin D levels will be dramatic. Life expectancy would also be extremely different."</p><p>But to try to explain the difference in fitness by vitamin D status alone is far too simplistic. "Vitamin D levels are a good measure of how sick someone is. But not more," says Fassnacht. </p><p>According to Fassnacht, none of the intervention studies carried out to date -- that specifically examined the effect of vitamin D on various diseases -- has been able to confirm the previous association and laboratory studies or the presumed positive effect of vitamin D.</p>
Further Research Is Needed<p>"If a coronavirus infection is suspected, it is therefore absolutely necessary to check the vitamin D status and quickly correct any possible deficit," said the recommendation of the paper published by the University of Hohenheim.</p><p>"Studies are underway to see whether vitamin D helps in COVID-19 infection, but I personally do not believe that this is really the case," says endocrinologist Fassnacht. Nevertheless, he says it is of course useful to carry out these studies.<br></p><p>"I don't want to rule out that there are actually subgroups of people who benefit from an additional vitamin D dose," he says. After all, this has been proven to be the case with a severe deficit.</p><p>In view of the study situation, Fassnacht does not think much of preventive, nationwide vitamin D substitutes. "My belief that the vitamin helps somewhere is very low. But, of course, I can be wrong."</p>
