Whole foods: nutritional benefit of yam




Yam contains considerable energy (118kcal/100g) and contains moderate amount of B group vitamins, vitamin C and minerals among which potassium is significant. Yams lack pro vitamin A. 

It has been proven that yam contains a steroid that stops peroxidation of blood lipids ( the principal cause of arteriosclerosis) and lowers the level of triglycerides, which are a type of fat in the blood. All of this, together with their low fat content and their richness in potassium makes yam very appropriate for cardiovascular disorders, particularly arteriosclerosis.

NB: Arteriosclerosis (Hardening and thickening of the walls of the arteries. Arteriosclerosis can occur because of fatty deposits on the inner lining of arteries (atherosclerosis), calcification of the wall of the arteries, or thickening of the muscular wall of the arteries from chronically elevated blood pressure (hypertension)

Do Bananas Have Too Much Sugar?



Are you or your loved ones banana fans? It's easy to love bananas: They are self-enclosed, completely biodegradable travel snacks and tasty to boot! What is there not to like?

Do Bananas Have Too Much Sugar?

Bananas' sweetness and appealing "banana-y" flavor may lead some to believe they are very high in sugar. This isn't true: They are very comparable in carbohydrates to other fruits. Here are some numbers for comparison:
  Banana Apple Grapes
Serving Size 1 large 1 large 1 cup
Calories 121 kcal 116 kcal 104 kcal
Total Sugar 16.6 g 23.2 g 23.4 g
Total Carbohydrates 31 g 30.8 g 27 g
Fiber 3.5 g 5.4 g 1 g
Glycemic Index
Low: less than 55
Unripe: 31
Ripe: 51
28 to 44 depending on type and ripeness 43 to 53

Bananas and Blood Sugar

People with diabetes or prediabetes may have received the suggestion to only eat half a banana in one sitting. This is because bananas vary widely in size and can therefore have a different impact on blood sugar depending on the portion size. An extra-small banana (6 inches long or less) has 18.5 g carbohydrates, whereas a large banana (8 to 8 7/8 inches long) has 31 g carbohydrates. So bananas can fit into a diabetes meal plan as long as you plan accordingly.

Other Nutrients in Bananas

Bananas are also high in potassium and Vitamin B6, and are a good source of fiber. Potassium is an important nutrient that counteracts the blood-pressure-raising effect of sodium, while Vitamin B6 is involved in many metabolic processes in the body, such as protein metabolism, production of neurotransmitters, glucose and glycogen metabolism, immune function, and hemoglobin formation. Another plus: A 2008 study from Uppsala University in Sweden suggests that a phytonutrient called 2-pentanone, commonly found in bananas, may help prevent the development of colon cancer.

The Bottom Line

Relax: Just like many other fruits and vegetables, bananas contain beneficial nutrients including vitamins, minerals, and phytonutrients. This isn't a reason to consume solely bananas, of course. Instead, aim to get a wide variety of fresh produce with different colors to get the maximum benefit.

Want to Get Healthy? 10 Reasons Why Lemons Are the Key



Saying that lemons are a superfood is an understatement. Not only do they add abundant flavor to a variety of dishes, but they also boast a ton of health benefits. The flavonoids within the juice are said to contain antioxidants, which is why lemons are useful in treating so many ailments and conditions. Here are 10 reasons to enjoy them ASAP.

- Prevent kidney stones: Drinking one half-cup of lemon juice every day raises citrate levels in the urine. Studies have shown that this could protect against calcium stones in the kidney.

 - Soothe a sore throat: Mixing lemon juice with honey can help alleviate the discomfort that comes from a nasty sore throat.

- Support weight loss: Beyond the old notion that the Master Cleanse was the only way lemons could help you lose weight, new studies have shown the ways lemon juice supports your goals. Lemon juice contains pectin, a soluble fiber that has been shown to aid in weight-loss struggles.

- Start your day right: Leave caffeinated drinks behind, and start your day off with hot water and fresh lemon juice to stimulate your digestive track and add vitamin C.

 - Stop an itch: When it comes to poison ivy or insect bites, rubbing lemon juice on the area can soothe the skin, since it has anti-inflammatory and anesthetic effects.

 - Aids in digestion: Dr. Oz is a big believer in the power of lemon juice for weight loss. He suggests drinking a mixture of lemon juice and flaxseeds in order to eliminate waste more quickly from your body.

- Anticancer properties: Studies have supported the anticancer activity of citrus liminoids, compounds that protect your cells from damage that can lead to the formation of cancer cells.

- Potassium power: Bananas aren't the only way to get a big helping of potassium in your system. In addition to vitamin C, lemons offer 80 milligrams of this mineral that helps your body stay strong and nimble.

- Bring down a fever: Forget the days of starving a fever! When your temperature goes up, drinking a lemon juice mixture can help bring your fever down faster.

- Balance pH: While lemons may seem quite acidic, they're a surprisingly good source of an alkaline food that can help balance your body's pH.

Green Tea: Good for Your Heart and Brain

2015-02-17-GreenteaAGirlWithTea.jpg


Tea has been cultivated for centuries and remains one of the most widely consumed beverages in the world. Sipping a cup of green tea can offer much more than refreshment: the positive health benefits are impressive and well-documented. The delicate leaves of green tea are packed with cell-protecting polyphenol phytochemicals called catechins that have significant medicinal and antioxidant properties. They have been shown to protect against heart disease, cancer, cell damage from oxidative stress as well as promote brain health.

Anti-Cancer Effects
Eipgallocatechin gallate, or EGCG, is a potent polyphenol catechin in green tea that has been the most extensively studied and shown to have the greatest anti-cancer effects. In addition to helping prevent cancer, studies have shown that EGCG also inhibits cancer cell growth by preventing one cancer cell from splitting into two cells and inhibiting the mechanism that spreads cancers cells. It also repairs the UVB-induced DNA damage in skin cancer.

EGCG and Your Heart
EGCG also has the highest number of anti-oxidant properties with beneficial effects on the prevention of cardiovascular disease. These protective benefits for heart disease come from the plant compound's ability to improve blood flow, lower cholesterol and blood pressure, and protect against the oxidation of LDL particles that can lead to atherosclerosis. A study of 40,530 people in Japan, where green tea is most widely consumed, found that drinking green tea lowered the risk of mortality from cardiovascular disease by 31 percent in women and 22 percent in men.

What's Good for Your Heart is Good for Your Brain
EGCG in green tea has been shown to protect brain cells and have neuroprotective agents that protect against neurodegenerative disorders such as Parkinson's and Alzheimer's. The studies show that EGCG can be protect against the formation of beta-amyloid plaques that are thought to contribute to Alzheimer's. Studies have also shown that it potentially helps to improve working memory.
The nutrition guidelines for the Dr. Dean Ornish Program for Reversing Heart Disease suggest avoiding caffeine; however, green tea is an exception due to the significant well-studied benefits on health and heart disease. The nutrition guidelines recommend limiting green tea to 2 cups a day since it still does contain caffeine, which is a stimulant. Green tea, however, does have a calming effect that counteracts the high and jitteriness caused by caffeine because of its concentration of an amino acid called L-theanine. L-theanine boosts alpha wave activity in the brain that produces a state of relaxed concentration. A meta-analysis of 13 randomized control studies found that this relaxation effect also decreases blood pressure.

Caffeinated V. Decaffeinated
A cup of green tea has anywhere from 20-45 milligrams of caffeine, which is lower than black tea or coffee, which averages 145 to 200 milligrams per cup. Decaffeinated green tea has less caffeine, but the process to remove the caffeine also strips it of the beneficial polyphenols. If you do choose green tea that has been decaffeinated, select a brand that uses an "effervescence" method, which is a natural process using water and carbon dioxide without chemicals that preserves most of the polyphenols present in regular green tea. To derive the most benefit, drink freshly brewed green tea and avoid powdered tea, sweetened or bottled, which contain fewer polyphenols.

The Most Benefits
The concentration of theanine, EGCG and other elements are most abundant in fresh, high quality loose leaf green tea. The concentration can vary depending on the brand. Steeping tea in hot water for three to five minutes will most effectively extract the powerful polyphenol activity of EGCG.

What effect have you noticed when you replace your daily coffee with green tea?

Best ways to manage stress





 Meditation can trigger the     antidote to stress, called the relaxation response
Goal setting and relaxation techniques reduce stress and ease the physical and emotional burden
it can take.
Stressful experiences come in many forms, such as a demanding job, a chronic disease, or an argument with a loved one. But all types of stressors—even stress from positive experiences,
such as planning a party—can result in the same physical and emotional burden on health, especially when you’re an older adult. “As we age, our immune systems are less efficient, and adding stress to that can lead to disease progression or the onset of disease,” says Dr. Ann Webster, a health psychologist at the Benson-Henry Institute for Mind Body Medicine at Harvard-affiliated Massachusetts General Hospital.

The stress response

Stressful situations trigger a physical reaction known as the stress response. The brain relays warnings to the muscles, which tighten, and to the adrenal glands, which release stress hormones such as adrenaline and cortisol. These hormones help your body prepare to fight or flee to safety: your heart pounds, blood pressure rises, and more of your blood is sent to your brain and muscles; your breath quickens to get more oxygen into your blood; and your body releases sugars and fats into the blood for energy.
In the short term, the stress response can help you navigate a difficult situation. But chronic stress can lead to physical damage. “Stress increases blood sugar and can make diabetes worse. It can create high blood pressure and cause insomnia. It can also make people become anxious, worried, depressed, or frustrated,” says Dr. Webster. Chronic stress also increases the risk of heart disease, heartburn, and many other health problems.

Recognizing stress

Symptoms of stress can take many forms. Stress may cause physical complaints, such as tension headaches, back pain, indigestion, or heart palpitations. It may appear as cognitive problems, such as poor concentration and indecisiveness. Emotional symptoms of stress include crying, irritability, and edginess. And stress can also show up as negative behaviors. “Driving a car too fast, overeating, or smoking can all be behavioral symptoms of stress,” says Dr. Webster.

Managing stress

The first step toward reducing stress is learning what your triggers are. “If you know what pushes your buttons, then avoid it. But there are stresses we have to accept, so we must change our reactions to them,” explains Dr. Webster. She offers the following ways to reduce or manage stress:
  • Relaxation techniques. These are activities that trigger the relaxation response, a physiological change that can help lower your blood pressure, heart rate, breathing rate, oxygen consumption, and stress hormones. You can achieve this with activities such as meditation, guided imagery, yoga, and deep breathing exercises.

  • Cognitive behavioral therapy (CBT). CBT is based on the idea that changing unhealthy thinking can change your emotions. A CBT therapist will help you identify negative thinking and learn to automatically replace it with healthy or positive thoughts.

  • Goal setting. “When people set goals for themselves, they have a positive sense of commitment, feel they’re in control, and are optimistic,” says Dr. Webster. She recommends setting goals in your career, relationships, creativity, play, and health.

How to Rid Yourself of Belly Pooch Forever


Clean eating and hitting the gym can help you reach your weight-loss goal, but you might find you have a little extra pooch around your midsection. Here are three things you can do to help you achieve a trimmer belly.

When Eating
Take an honest look at your diet and your bathroom schedule. Your belly might not be caused by fat but by air trapped in your digestive system. If you're not getting enough fiber (you need 25 to 30 grams a day), constipation can cause bloating. On the other hand, overdoing it on fiber or eating too many gas-producing foods like broccoli, apples, or beans can also make your belly pooch a bit. Thankfully, there are also foods you can eat—like blueberries—that are proven to diminish belly fat.


When Doing Cardio
Studies show that including interval training in your cardio sessions is proven to diminish stomach fat. If you find that you normally stick to a consistent pace when running, biking, or swimming, mix it up by adding 10- to 60-second, fast-paced or sprinting intervals. High-intensity interval training (HIIT) works on the same principle as intervals, where you push to your maximum training for a period of time and follow up with a shorter rest period. 


When Strength Training
Basic crunches can help tone your abs, but they only target certain abdominal muscles. Incorporate full-body exercises like variations of plank or core moves using a ball. Also, try using different types of equipment.
