It’s Squash Season!

I love winter squash! It’s probably one of my favourite vegetables! Winter squashes come in all different shapes, sizes and colours. They are diverse in appearance but all are solid in nutritional quality. Due to its orange colour, squash is a superb source of the carotenoids beta-carotene and lutein. Carotenoids which ac as antioxidants, reducing free radical damage, and may prevent heart disease. Lutein may also help preserve eye health by decreasing the risk for macular degeneration. Squash is also a source of potassium which is an electrolyte involved in fluid and electrolyte balance for the body as well as heart health and blood pressure regulation. Like most fruits and vegetables squash also offers Vitamin C. Folacin, also found in squash, functions in the prevention of birth defects and reduces the risk of certain cancers and heart disease. Of course, if you’ve ever tasted the creamy, smooth and satisfying texture of a squash you will realize that it is also an excellent source of fibre, which helps regulate cholesterol levels and keep digestion regular. 1 cup of cooked acorn squash has 11 grams of fibre which is almost 50% of what you need in a day! Fibre is important for keeping your regular as well as Winter squash is also a low-fat source of Vitamin E.

Squash seeds are also very nutritious. They are a good source of iron, another important mineral involved with oxygen transportation in the book. Save the seeds from your squash, wash them and let them dry and then bake them in the oven at 275F for about 15 min until they are crispy and crunchy.

Squash starts to become available towards the end of August. They are a harvest vegetable and once harvested and stored properly you can find local squash available until about March. It’s an great ingredient for many fall and winter dishes because of it’s heartiness and time of availability.

When buying a squash pick one that has a hard surface free of soft spots and bruises. You can buy a squash and keep it stored in a cool dry place with good air circulation for a couple of weeks.  Be sure to turn it over every once in a while to make sure that there are no mushy spots hiding underneath!

There are so many things you can do with squash. It’s amazing! But due to its hard flesh winter squash will have to be cooked before it is eaten. Most often you will hear of roasting squash. This is an easy way to cook it. Cubes of squash can also be added to soups, stews and chilies. Squash soup gives a creamy consistency when it is pureed which is one of the beauties of squash soups. It’s also used in sauces to give that same creaminess – without the cream and extra fat and calories.

Become Unbeatable … with Beets!

There is something stunning about the deep ruby red beet that creates a dramatic effect wherever and whenever it is presented. Beets don’t have to be red though, although that is probably the most common conceptualization of this vegetable; they also can be yellow or striped. Did you know that not only can the roots be eaten but you can also eat the leaves?

So, what are the benefits of beets? With their deep colour it’s understandable why beets are a stellar source of many vitamins and minerals that are essential for good health and nutrition. As with other fruits and vegetables beets provide Vitamin C, a vitamin that also acts as an antioxidant. Folacin, a powerful B-vitamin with preventative effects for birth defects, cancer and heart disease. Potassium found in beets may contribute to reducing the risk of heart disease and stroke. Iron is another important mineral found in beets.

When buying beets try and get ones that are equal in size so that they will cook evenly. Make sure your beets are firm and their skin is dry and there are no mushy parts. Keep your beets in a cool dry place, like the refrigerator, loosely wrapped in a paper towel. If you are not going to eat the beet leaves you can chop off the stalks for easier storage.

Before cooking your beets scrub them well under running water to remove the dirt. Then dry them well with paper towels.

Beets have many different uses. You can roast them, boil them, steam them. They can be pickled (I’ve always have a thing for the little pickled salad beets!). You can shave them and add them to salads raw. Beets can be added to smoothies or beet root juice is also very popular. And of course they are the signature ingredient in Borscht – a traditional Eastern European soup.

If you can, try not to peel the beets before you cook them. Leaving the skins on preserves valuable nutrients, as well as the colour of the beets. It’s okay to leave the beet tops on and remove them after cooking.

A big question in preparing beets is “what to do about the red stains”? Beets will stain your hands if you handle them either raw or cooked. The simple solution is to wear gloves. Just get a thin pair of plastic gloves. Beets will also stain surfaces. Wood and marble are especially difficult to get stains out of. You can remove the skins of cooked beets with paper towels. Cover surfaces with parchment paper to prevent beet staining.

Beets and Athletic Performance

One area of interest for beets in research is for their effects on athletic performance. Beets have been found to improve endurance and athletic performance. Beet root and beet root juice have been tested in various studies, such as this one in the Journal of the Academy of Nutrition and Dietetics, which  found that consuming whole beetroots improved performance with increased running velocity and decreased ratings of perceived exertion. Beets provide these effects because they are a natural source of nitrates which increases nitric oxide bioavaiability which is important to exercise performance.

FYI – Beets are red because of the red pigment “betacyanin”. Some people cannot properly metabolize betacyanin and it will pass through the digestion process unchanged and then be excreted. This is not something to be worried about.

Meet the Superheroes in Your Diet

Super heroes are an important part of our culture. We all love our super-heroes. And for our bodies their superheroes are called antioxidants. The main function of antioxidants is to protect our cells from oxidative damage. Antioxidants may also improve immune function and help prevent chronic diseases such as cancer and heart disease.

Oxidation is a natural process of life, it’s one of the contributors to aging. It is a reaction that occurs for various reasons, and results in the production of free-radicals.

The free radicals produced by oxidation are like the villains, they damage the cells of our bodies because they are what we call “unstable” meaning they are missing an important part of themselves – an electron (special sub atomic particle) from their outermost electron orbital. As a result, they are always looking to steal an electron from any innocent cell to complete their orbitol.

It follows that free radicals will produce more free radicals which will do more damage to our bodies. So it’s important we find ways to defend ourselves and stop the destruction before it goes too far. There are many reasons the free radicals get produced in the body, some of them you can avoid like smoking, others not so much like air pollution, sun exposure. EVEN exercise produces free radicals.

Your mission is to counteract the destruction caused by free radical production and save our cells by choosing foods which provide antioxidants to support our systems.

Super hero veggies

But where do we find antioxidants? Fruits and vegetables are the number one go to source for antioxidants. Eating the right number of servings of fruits and vegetables everyday is the best way to get your antioxidants. Other sources include: whole grains, nut and seeds, coffee, tea and even chocolate.

Here are some examples of nutrients that may function as antioxidants and where you can find them:

Vitamin E

Vitamin E is considered one of the, if not the greatest antioxidant.This is the primary function of the vitamin. Nuts and seeds (especially sunflower seeds!), vegetable oils and avocado are very high in vitamin E.

Vitamin C

Most fruits and vegetables, but especially citrus fruits like oranges and grapefruit, will give you Vitamin C. Where Vitamin C is concerned, fresher is better, and you don’t want to overcook your veggies because excessive heat and oxygen destroys Vitamin C.

Vitamin A

Vitamin A has many functions and one may be to act as an antioxidant. Vitamin A is particularly important in keeping eyes and skin healthy. Find Vitamin A in meat, specifically liver, as well as dairy products and fish.

Selenium

Selenium is a mineral that functions as an antioxidant. Brazil nuts are very high in selenium. Meat, poultry, seafood, eggs, beans and grains products also provide selenium.

Carotenoids

Carotenoids are a group of compounds that act as antioxidants. They include beta-carotene, lycopene (found in tomoatoes), lutein, and zeaxanthin. Carotenoids are pigments which give colour to many fruits and vegetables dark green, orange, yellow and red. Beta-carotene is a carotenoid may have additional benefits because it is converted to Vitamin A, another antioxidant, in the body.

Flavonoids

Flavonoids are another group of compounds, many of which have been shown to have antioxidant properties. Flavonoids are found mainly in berries (especially dark coloured ones like blueberries), onions, apples as well as cocoa (think chocolate!) tea (particularly green tea) and wine.

Antioxidant Supplements

There are many supplemental forms of all of these nutrients available. However, as long as you follow an adequate, balanced and nutritious diet and have all the recommended servings of fruits and vegetables, in every colour, you should have no trouble meeting your body’s antioxidant needs and therefore not require supplementation. More research is needed into the validity of antioxidant supplementation. You can have too much of a good thing and some antioxidants, like the fat soluble vitamins A & E can be toxic if you exceed the recommended amount.
