The notion of using food to prevent or delay the onset of certain ailments is centuries old—Hippocrates himself is famous for saying “Let food be thy medicine and medicine be thy food.” But, as more and more research is devoted to exploring how what we eat affects what diseases we get, the movement is just now gaining mainstream attention.
Recently, the Journal of the American College of Nutrition featured a list of dietary pointers compiled by the Physicians Committee for Responsible Medicine—a nonprofit group of health care professionals who advocate for preventive medicine—aimed at reducing a person’s risk for developing certain types of cancer.

The argument that good nutrition is enough to ward off deadly diseases has its fair share of supporters and detractors. But the authors of the guidelines point out that their recommendations are “based on the principle that diet changes are justified, even when evidence on certain issues are up for debate.”
Here are a few of their tips:
Steer clear of red and processed meats.
Eating just one simple sausage link per day could up your colorectal cancer risk by 20 percent, while a small steak could bump it up to 28 percent. This is due to the cancer-contributing compounds found in many red and processed meats—nitrites, too many amino acids, heme iron and heterocyclic amines.
Take it easy on the alcohol.
The notion that a nightly glass of red wine is good for your heart is often used as an excuse to imbibe more often. But you may want to go easy on that extra serving. An additional drink each week increases larynx, pharynx and mouth cancer by as much as 24 percent. And since it’s the alcohol—as opposed to the additives—that appears to create problems, no alcoholic beverage is entirely benign.
Beware of certain meal prep methods.
Broiling, frying and grilling meats contributes to the formation of heterocyclic amines (HCAs). Eating HCAs may impair DNA functioning in the body, which can aid the growth of colorectal cancer.
Decrease your dairy intake.
For men seeking to avoid prostate cancer, abstaining from too much dairy may be an important step. A daily regimen of two glasses of milk has been shown to increase prostate cancer risk by as much as 60 percent in some men. And calcium supplements aren’t necessarily safe either. Men who take more than 400 milligrams of calcium each day could up their chances of prostate cancer by 51 percent.
Make friends with fruits and veggies.
A well-worn piece of food wisdom that nonetheless bears repeating, evidence consistently shows that men and women who consume greater amounts of fruits and vegetables are healthier overall. Leafy greens and cruciferous vegetables (kale, cabbage and broccoli, in particular) may help reduce colon cancer risk by as much as 18 percent, according to the Physicians Committee experts. For women, carrots and sweet potatoes have been dubbed especially potent at combating breast cancer. And (even though you may need an extra breath mint afterwards) increasing your intake of allium vegetables like garlic and onions could cut your gastric cancer risk.
Certain women should seek soy.
Soy is a much-debated dietary element—especially when it comes to cancer. Some studies indicate that women who eat more soy have a decreased risk for developing breast cancer. Yet other investigations highlight a potential increase in cancer risk that corresponds with an increase in soy consumption. “Research on soy and cancer is highly complex, controversial and evolving,” according to Dr. Marji McCullough, strategic director of the American Cancer Society’s nutritional epidemiology and epidemiology research program. McCullough points out that the negative evidence against soy largely comes from studies conducted on mice and other rodents, which means that it may not be directly applicable to human beings. While the jury’s still out in terms of a definitive answer, McCullough says soy probably isn’t harmful, and the Physicians Committee doctors claim that natural forms of soy—organic tofu, tempeh and edamame are healthy options for women seeking to lessen their breast cancer risk.
In essence, these dietary recommendations closely mirror the ones espoused by many nutritional experts: load up on fruits and veggies, keep red meat and dairy products to a minimum, enjoy the occasional glass of alcohol and try to get most of your vitamins and minerals from natural foods, as opposed to supplements.
As study author Susan Levin, M.S., R.D., C.S.S.D., director of nutrition education for the Physicians Committee says, “There’s considerable benefit—and no harm—in loading up with plant-based foods. Large bodies of research show fruits, vegetables and legumes offer a variety of protective properties, so why not move these foods to the center of our plates?”
Typhoon Molave is expected to make landfall in Vietnam on Wednesday with 90 mph winds and heavy rainfall that could lead to flooding and landslides, according to the U.S. Embassy and U.S. Consulate in Ho Chi Minh City. To prepare for the powerful storm that already tore through the Philippines, Vietnam is making plans to evacuate nearly 1.3 million people along the central coast, as Reuters reported.

A stretch of coastline in the Philippine capital, Manila has received backlash from environmentalists. The heavily polluted Manila Bay area, which had been slated for cleanup, has become the site of a controversial 500-meter (1,600-foot) stretch of white sand beach.
Sand Makeup Crucial for Ecosystems<p>While UNEP/GRID-Geneva generally supports finding <a href="https://www.dw.com/en/not-enough-sand-for-construction-industry-despite-abundance/a-49342942" target="_blank" rel="noopener noreferrer">alternative sources of sand</a> so as not to disrupt ecosystems in rivers and oceans when extracting them, Vander Velpen stressed it was vital to use sand which closely matches the makeup of the native sand to protect beach fauna.</p><p>"If you change the core characteristics of the native sand, the original sand, you need to do an environmental impact assessment (EIA) to find out how it's going to impact the ecosystem and nearby ecosystems," he told DW.</p><p>But according to Torres, such an assessment was not done in Manila.</p>
Beautification Stunt Instead of Proper Cleanup?<p>Manila Bay's waters are heavily polluted by oil and trash from nearby residential areas and ports. A huge "No swimming" sign warns visitors to stay away from the ocean.</p><p>Philippines' <a href="https://denr.gov.ph/index.php/priority-programs/manila-bay-clean-up/25-priority-programs/1825-frequently-ask-questions-faqs-on-the-dolomite-and-the-beach-nourishment-project" target="_blank">Department of Environment and Natural Resources (DENR)</a> has denied dolomite sand poses any risk to human health and the ecosystem.</p><p>However, scientists of the University of the Philippines have come forward disputing the DENR's claims. A <a href="https://biology.science.upd.edu.ph/index.php/ib-statement-regarding-dolomite-in-manila-bay/" target="_blank" rel="noopener noreferrer">statement by the Institute of Biology</a> said that using crushed dolomite did not address any of the rehabilitation phases and instead was "even more detrimental to the existing biodiversity as well as the communities in the area," pointing to the case of water birds. "The dumping of dolomite in Manila Bay has effectively covered part of the intertidal area used by the birds thereby reducing their habitat."</p><p>At peak migration season, Manila Bay is home to 90 aquatic bird species, including species of international conservation concern that are facing a very high extinction risk in the wild. </p><p>Authorities should focus on protecting and conserving biodiversity, the Institute of Biology added. "Rehabilitating mangroves is an example of a nature-based solution that is cheaper and more cost-effective than the dolomite dumping project," the scientists said.</p><p>Moreover, <a href="http://www.msi.upd.edu.ph/" target="_blank" rel="noopener noreferrer">the Marine Science Institute</a> has warned that prolonged inhalation of finer dust particles of dolomite could "cause chronic health effects," leading to discomfort in the chest, shortness of breath and coughing.</p><p>They also warned dolomite sand grains would erode during storms and be carried out to sea, essentially being washed away.</p>
Rehabilitation vs. Reclamation<p>Environmentalists say covering up the beach doesn't address the real issues of the bay. Torres and others believe the best way to clean up Manila Bay is not to add anything, but rather remove trash and pollution.</p><p>"There have been studies saying much of the waste comes from already collected waste — so these are open dump sites along the coast that get washed up because of the rain," Torres said.</p><p>She criticized the authorities for continuing to push reclamation projects she says are at odds with each other. These projects will affect large areas of mangrove forests, she said, and experts warn that this, in turn, exacerbates coastal erosion.</p><p>"If you've removed the areas that helped trap the sand, like mangrove forests, then the likelihood increases that you will have to nourish a beach. Same as building right up to the waterfront," said Vander Velpen of UNEP/GRID-Geneva.</p>
Plenty of Sand in the Sea?<p>The question of Manila's contentious white beach echoes larger questions about sand mining worldwide. <a href="https://unepgrid.ch/storage/app/media/documents/Sand_and_sustainability_UNEP_2019.pdf" target="_blank">Global sand consumption has tripled</a> over the past two decades, UNEP/GRID-Geneva has found. A huge chunk of it is now taken up by construction.</p><p>"Many operate on the assumption that natural sand is endless in its supply," said Vander Velpen.</p><p>Sand scarcity is a concern shared by Stefan Schimmels of <a href="https://www.fzk.uni-hannover.de/fzk_start.html?&L=1" target="_blank">Forschungszentrum Küste</a> who's done extensive research on shore nourishment to stop coastal erosion. And as climate change and rising sea levels are threatening coasts, demand for sand will grow even more.</p><p>A large study, the <a href="http://www.stencil-project.de/wp-content/uploads/2019/10/STENCIL_SWOT_Analyse_191026.pdf" target="_blank">Strategies and Tools for Environment-Friendly Shore Nourishments as Climate Change Impact Low-Regret Measures (STENCIL project)</a>, focused on the German island of Sylt, a popular vacation spot.</p><p>About 1 million cubic meter of sand per year is used to maintain the coastal area of Sylt, STENCIL project head Schimmels said. That's about 100 million 10-liter buckets of sand.</p><p>When sand was extracted off the coast of Sylt, underwater craters were formed. "You can still detect these craters even decades later," Schimmels told DW.</p><p>"Also when you add a couple of meters sand onto the beach — you essentially bury all things that do creep and fly," he said. "How quickly will they recover?" Schimmels said more research was needed as there was still too little known about long-term effects on the environment. </p>
Criticism Piling Up<p>As for Manila's artificial white sand, it looks like some might have already been blown away by a recent storm. DENR claims it wasn't washed away, but said that grayish sand, stones and other material had simply piled up over the dolomite sand. People in Manila have tweeted photos showing how the storm has ravaged the beach. </p>
