Intestines Modify Their Cellular Structure In Response To Diet

Body organs such as the intestine and ovaries undergo structural changes in response to dietary nutrients that can have lasting impacts on metabolism, as well as cancer susceptibility, according to Carnegie’s Rebecca Obniski, Matthew Sieber, and Allan Spradling.

There are three major types of cells in fruit fly (and mammalian) intestines: Stem cells, hormone-producing cells, and nutrient-handling cells. Think of the stem cells as blanks, which are eventually programmed to become either hormone-producing or nutrient-handling cells. The authors discovered that this programming can be influenced by dietary nutrients and that young animals are particularly sensitive to these changes.

The effect of cholesterol is to promote the programming of more new, “blank” cells into hormone-producing cells rather than nutrient-handling cells. Conversely, decreasing dietary cholesterol results in more nutrient-absorbing cells and fewer hormone-producing cells.

Moreover, the researchers were able to identify the detailed molecular mechanism by which cholesterol causes these changes in cell fates, and to show that it is closely related to the way human intestinal cells regulate cholesterol production.

What does this mean?

It shows that low nutrient availability, especially early in life, such as the low-cholesterol diet for the fruit flies, triggers changes in intestinal structure and metabolism that have long-term effects. These changes persist for quite a while even if the diet changes, which can increase the risk of metabolic health problems down the road.

Sore point: Ancient Remedies For Toothache Often Worse Than The Pain

If you found a live frog in your mouth in 19th or 20th century Ireland, it probably wasn’t a kiss attempt gone awry. You were just probably trying to draw out its healing powers to cure a toothache.

If that didn’t work, you could try sucking on cloves. Or drinking water from the Holy Well. There was also the option of taking a tooth from a corpse.

These cures are among the many found in new research by Dr. Carol Barron of DCU’s school of nursing and human sciences and her research assistant, Tiziana Soverino, published in the Journal of the History of Dentistry.

Over 400 of the cures addressed in the folklore were for treatment of an aching tooth. They were categorized into plant and mineral, quasi-medical and magico-religious cures.

Other cures were slightly more quotidian than the frog method. Salt and water were two of the most widely used curative substances. Potatoes were kept in pockets acting as an amulet to ward off a toothache, and infected teeth were often packed with tobacco.

Can Dietary Changes Help With Microscopic Colitis?

Microscopic colitis is an inflammation of the bowel lining that doctors can only see under a microscope. It is often possible to treat this condition with medication, but dietary and lifestyle changes may also help reduce or prevent symptoms.

The symptoms of MC tend to come and go, and diarrhea can last for weeks or months. In some people, the condition may resolve without treatment. The cause of MC is still not clear.

Researchers are currently studying the possible connection between diet and MC.

There is little evidence to suggest a link between what people eat and the symptoms of MC. Researchers in Sweden published a study in 2016 that followed 135 people with MC over the course of 22 years and monitored their intake of the following:

  • Protein
  • Carbohydrate
  • Sucrose
  • Saturated, monounsaturated, or polyunsaturated fat
  • Omega-3 or omega-6 fatty acids
  • Fiber
  • Zinc

3 Effective Home Remedies To Ease A Sore Throat

Due to the change in weather, seasonal allergies or excessive use of air conditioners, a common problem that most people face from time to time is a sore throat. Just like a cold, a sore throat can be frustrating as you deal with the annoying itch and pain in your throat.

While there are many medications that one can take to get rid of a sore throat, you can also resort to natural home remedies to ease the condition and build your immunity.

1. Pepper water
The fact that black pepper is an incredible ingredient when it comes to fighting cold, cough and flu is not unknown. Thanks to the presence of the essential oil called piperine, which helps in fighting viruses and bacterial infection, and in relieving chest congestion.

2. Ginger, honey and lemon
This has got to be one of the most common remedies you will come across in most Indian households. Gingerol in ginger has powerful anti-inflammatory and antioxidant properties. Honey is known as a natural healer and an antibiotic. And lemon with its high Vitamin C content can help boost the immune system and fight off infection.

3. Haldi doodh
Haldi doodh or turmeric latte may be getting a lot of attention in the recent years, but since the ancient times, it has been a part of Indian traditional diet. Turmeric is known for its miraculous properties because of its rich bio active compounds called curcumin. As such it is a great antibacterial, anti-inflammatory, antioxidant and immunity boosting agent. It also helps in breaking up mucus and provide pain relief.

Sustainable Nutrition: A New Term for An Old Concern

Food security is a most basic human need. Historical accounts show that for centuries, human societies around the world have raised concerns about our food supply. This contemplation has driven innovation and we have, quite successfully, adapted to feed and nourish people.

With increasing constraints on our planetary boundaries — we’re not getting more land any time soon — and a growing world population, the areas of sustainability and human nutrition have merged into a new conversation: sustainable nutrition. This convergence is more of an evolution than a revolution. Thomas Malthus’ 1798 essay on population growth made a similar warning as contemporary concerns about nutrition and sustainability — demand for food will outpace our ability to produce it.

For food insecure populations, this is especially true, and these populations are not only in the developing world but exist even in developed, wealthy nations such as the United States, where one out of every six children is raised in a food insecure household. Yet, growing demand for animal-sourced foods, has been called unsustainable by some who argue that raising demand for nutrient rich animal-sourced foods cannot be met without exceeding environmental boundaries.

According to the USDA Economic Research Service, grazing lands make up nearly 800 million acres or 36 percent of the U.S. land area (Figure 1). Of that 800 million acres, only 12.8 million acres is classified as cropland pasture — grazing lands that could be converted to growing crops without major improvements. In the scenario of converting grazing lands to croplands, negative consequences would be expected. For example, the rates of soil loss on cultivated cropland are over four times greater than pastures, and the loss of grasslands can mean decreased habitat for wildlife.

Controversy Over Genetically Modified Organisms

It all began in 2004 when Nigeria signed a Memorandum of Understanding (MoU) with the United States government to support genetically modified crops after which a Biosafety Law was enacted in in April 2015. Since then the question has bordered on whether Genetically Modified Foods (GMFs) are good substitutes as claimed by some experts? If the GMFs are indeed a boost to crops, they why all the furor about it with several countries imposing a ban on their production?

In attempting to allay the fears about of GMOs, the Open Forum on Agricultural Biotechnology in Africa (OFAB) gave a response in one of its policy briefs, saying that “in real life nothing is absolutely safe but a degree of certainty is assured compared to other conventional breeding procedure.

Experts in the health sector have argued that natural foods are the best for healthy living as GMOs are experimental foods that can lead to health complications for humans later in life. As such, they could create more problems than they tend to solve.

The argument sustaining this project are that the process would lift farmers from subsistence to commercial farming, that it helps to develop a variety of crops that repel insects, and that GMOs are not synthetic. It has also been said that it could help to prevent stunted growth in Nigeria, with the country once recording the highest rate of stunted growths.

The issue of GMOs today is still a very controversial topic in Nigeria. It is worth noting that in March 2015 the World Health Organisation (WHO) classified glyphosate, the key ingredient in herbicides and pesticides, as carcinogenic.

5 Food Swaps for a Low Glycemic Index Diet

One key phrase that’s been popping up over the years is low GI, but what does that really mean? And why is it talked about so much?

The Glycemic Index (GI) is a ranking of how quickly foods with carbohydrates are absorbed by the body and how they affect your blood sugar levels.

“Eating high GI foods (think lollies, soft drink, white pasta) can cause a spike in you blood sugar after you eat. Big spikes in your blood sugar levels tend to give you only short-lived energy leaving you feeling lethargic and possibly hungry soon after eating. Foods with a lower GI (wholegrains, fruit, dairy foods) can provide a more steady release of energy helping you feel your best,” says Lyndi.

If you’re scratching your head wondering where to start, here are some easy tips.

  1. Swap white bread for wholegrain bread
  2. Swap jasmine rice for basmati rice
  3. Swap potato chips for nuts
  4. Swap regular potatoes for sweet potato
  5. Swap instant oats for traditional rolled oats

The Protest Against GMO

Recently, a study by the Centre for Science and Environment (CSE) found that 32% of the 65 tested food products comprised GM materials. These were being sold without any control from health and food regulators.

Numerous persons and organisations — under the banner ‘India For Safe Food’ — met the Karnataka Food Safety Commissioner on Monday demanding the removal of unapproved genetically modified food from the market.

Those in the India for Safe Food had approached the Food Safety and Standards Authority of India (FSSAI) for action, and receiving little response, they approached the State government’s body on Monday.

CKD: How This Diet Can Help In Managing Kidney Diseases

Eating a healthy diet is an important aspect of maintaining a healthy weight and good health. Eating healthy foods help in building a strong immunity. People suffering from chronic kidney disease (CKD) should consume a balanced diet.

A healthy and balanced diet helps patients with chronic kidney disease to be less dependent on dialysis. It helps in improving their blood sugar levels and blood pressure. Most patients of kidney disease, who do not even need dialysis, don’t consult a dietitian because of lack of awareness of simple ignorance.

According to a latest research published in Journal of the Academy of Nutrition and Dietetics, most patients of chronic kidney disease remain uninformed about how chronic kidney disease diet influences management and progression of chronic kidney disease.

People on dialysis need to take large amounts of protein from their diet. They need to restrict salt, potassium and water content in order to maintain their blood pressure. “Usually patients with chronic kidney disease should take 0.6 gm to 0.8 gm protein per kg of their body weight, before dialysis. These proteins should be good quality protein, from dietary sources such a milk and milk products or meat. Patients on dialysis need to get 1 gm to 1.2 gm protein per kg of their body weight,” says Dr Vijay.

Concerned About GMOs in Your Food?

On the surface, GMOs seem like a change for the good: Genetic modification can help plants resist pests and viruses or grow more quickly. However, since we are essentially combining DNA from different species, there is the potential that the plant will be forever altered. When a species changes, it opens parts of the environment to new competitors, which could have adverse consequences.

Although the FDA approved genetically modified salmon for consumption in 2015, some groups express concern that modified fish could negatively affect other fish populations.

GMO Labeling Gains Steam

The debate surrounding GMOs is not whether they should be legal, but whether they should require labeling. That’s because GMOs are present in a large percentage of the foods we buy at the grocery store.

The argument in favor of labeling genetically modified foods is that consumers have a right to know what they’re eating. 64 countries currently require GMO labeling. The argument against labeling includes increased costs and fear of public backlash over largely unproven risks.
