Beta-Carotene

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.

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.
