Beta-Carotene

Beta-carotene has two important functions in the body: It functions as an antioxidant, protecting cells against damage, and it can be converted to Vitamin A (retinol), critical to maintaining skin and eye health.

Without beta-carotene, our bodies are unable to manufacture Vitamin A. And without sufficient Vitamin A, nearly all of our systems are at risk, including lungs, kidneys and immune function. Research shows that people who consume the necessary levels of beta-carotene are able to lower their risk for coronary artery disease, stroke, macular degeneration, and other age-related diseases.

You can get beta-carotene from a variety of foods:

• Apricots
• Asparagus
• Broccoli
• Carrots
• Chinese cabbage
• Yam/Sweet Potato
• Spinach
• Kale

The National Institutes of Health recommends a daily intake of 3,000 IU for adult men and 2,310 IU for adult women. For children, amounts vary according to age. While beta-carotene deficiency is rare in most industrialized countries, it can be difficult getting the recommended levels simply from food. That's where supplements come in. In consult with your healthcare practitioner, design a plan that meets your individual needs. You may want to consider a supplement with a mixture of carotenoids, including beta-carotene, alpha-carotene, lycopene, astaxanthin, lutein and zeaxanthin.

It's possible to take too much beta-carotene. This is usually indicated by a yellowing of the skin, palms or soles and is known as carotenemia. Once consumption of beta carotene is reduced, this yellowing fades over time. As always, your best outcomes are achieved when working closely with Dr. Bossio or your healthcare practitioner.

Sweet Potato

Sweet Potato is a powerhouse of nutrition. This vibrant orange tuber is rich in vitamins, antioxidants, anti-inflammatory nutrients, and blood sugar-regulating nutrients. The antioxidant Beta-carotene, which gives Sweet Potato its orange flesh, is necessary for your body to produce Vitamin A. We need vitamin A for eye health, for a strong immune system, and for healthy skin. One medium Sweet Potato provides 100% of your daily needs for Vitamin A, as well as a healthy dose of vitamin C, several of the B vitamins, potassium, calcium, iron, magnesium, zinc, and vitamin E.

Some research has shown that, as antioxidants from Sweet Potato (called cyanidins and peonidins) and other phytonutrients pass through the digestive tract, they act in ways that may lower the health risk posed by heavy metals. Scientists are also studying the anti-inflammatory nutrients (anthocyanin) contained in purple Sweet Potatoes, which may provide protection against certain types of cancer. Sweet Potatoes also have a fascinating ability to potentially improve blood sugar regulation. Researchers are interested in determining what effect this may have on Type-2 Diabetes. High in fiber, including Sweet Potato in your diet can promote regularity of the bowels and healthy digestive function.

You can enjoy Sweet Potato as a main course, side dish, in soups, or in desserts. When shopping for these versatile veggies, remember that Yams are not the same as Sweet Potatoes. The two are not in the same "food family" and each has a different nutrient profile. Yams are usually imported from Africa or Asia, whereas the Sweet Potato is grown abundantly in the U.S. Finally, Sweet Potato color, both flesh and skin, can range from white to yellow-orange to brown or purple. There also are "firm" or "soft" varieties, which can make a difference in your cooking

Pumpkin

From Shakespeare's reference to "pumpion" in The Merry Wives of Windsor to The Legend of Sleepy Hollow, pumpkin is woven into the fabric of history and cuisine. Native Americans roasted long strips of pumpkin over an open flame and ate them. Colonists made pumpkin pie by slicing off the pumpkin top; removing the seeds; filling the rind with milk, spices, and honey; and then baking the pumpkin over hot ashes. And we all know pumpkin transforms into Jack-o-lanterns for Halloween decor. Today, we appreciate pumpkin not just for culinary traditions, but also for its abundance of nutrients and versatility in healthy meal preparation, such as soufflés, soups, bread, jam, butter, and desserts.

A member of the Cucurbitaceae family of vegetables (along with cucumber and squash), pumpkin is cultivated around the world for both its fleshy vibrant orange meat and seeds. It is a naturally low calorie (49 calories per one cup serving), yet filling food that offers the following health benefits:

Health Benefits

• Pumpkin contains no saturated fats or cholesterol. It is rich in dietary fiber, antioxidants, minerals, and many antioxidant vitamins, including A, C, and E.
• It is also an excellent source of many natural polyphenolic flavonoid compounds such as beta-carotenes, lutein, and zeaxanthin. Carotenes convert into vitamin A inside the body. Zeaxanthin is a natural antioxidant that may offer protection from age-related macular disease.
• Pumpkin is a good source of the B-complex group of vitamins including niacin, vitamin B-6 (pyridoxine), thiamin, and pantothenic acid.
• It is a rich source of copper, calcium, potassium, and phosphorus.
• Pumpkin seeds provide dietary fiber and pack a powerful mix of protein, minerals, and vitamins: 100 g (1 cup) of pumpkin seeds provide 559 calories, 30 g of protein, plus folate, iron, niacin, selenium, and zinc.
