Understanding lactose intolerance

Lactose intolerance comes from a deficiency in an enzyme needed for digesting lactose, called lactase. Lactase is an intestinal enzyme that breaks down lactose to glucose and galactose, which are simple sugars. Lactase concentration is high at birth but declines steadily in most people of non-European ancestry after weaning. This normal decline occurs to a greater extent in some people than in others.

Bad food, bad brain?

When you think about your diet, you probably think about what it does to your figure.

The Kale Controversy!

No less a magazine than Mother Jones recently published an account of an alternative medicine researcher claiming the truly horrifying: kale might be bad for you. His patients, otherwise healthy, started presenting with digestive problems, fatigue, and skin and hair problems. He found that a lot of them had elevated thallium levels — and that a lot of them ate significant amounts of brassicas, the plant family that includes kale and cabbage. When he had some patients remove these foods from their diet, their thallium levels dropped and their symptoms improved.

Watch out, vampires! We can’t get enough of garlic’s health benefits

Garlic has been in use at least since the beginning of recorded history. It’s been found in ancient Egyptian pyramids and Greek temples. Ancient medicinal texts show beneficial uses in Egypt, Greece, Rome, China and India. The Greek physician Hippocrates prescribed garlic for a number of conditions. Garlic was fed to Greek soldiers to give them courage for war and Olympic athletes to increase their performance. In ancient China and Japan, it was used as an aid for digestion and respiration and as a food preservative. In India, it was used for digestive diseases, parasites, arthritis and heart disease. In Europe in the Middle Ages, it was used as a treatment for the plague.

Could periodic fasting improve your blood sugar and weight?

Fasting has been a part of many religions’ traditions for a long time, but some people are fasting for health reasons. Since at least the 1970s, researchers have studied the effects of occasional or "periodic" fasting, or reduction in daily caloric intake, on animals and humans. Now we know that fasting may increase antioxidant activity and help to lower blood sugar and insulin levels. The consensus on the topic is growing, and indicates that fasting can have many health benefits.

Gotta have that java? Know the pros and cons of coffee!

What is oleic acid and how much do you need?

Most people are familiar with the omega-3 and omega-6 fatty acids, but what is oleic acid, and why is it important? Oleic acid is a naturally occurring, odorless, colorless oil. Oleic acid is found in flaxseed oil, borage (a Mediterranean herb) oil, evening primrose oil, olive oil (less in virgin olive oil), pecan oil, canola oil, peanut oil, macadamia oil, sunflower oil, grape seed oil, sea buckthorn oil and sesame oil. You can also find it in animal fat. Oleic acid at appropriate levels has been implicated in cancer prevention in some (but not all studies), and reduces cholesterol levels.

3, 6, 9: What are the different omega fatty acids?

Essential fatty acids (omega-3 and omega-6) are indeed essential for your health, but they cannot be produced in the body, so you need to get them from foods or supplements. Ideally, your diet would have a healthy balance of both omega-3 and omega-6 fatty acids, but the modern American diet tends to be richer in omega-6. Unless you are following a Mediterranean diet, you could probably use some more omega-3! Let’s take a look at what the different “omegas” do.
