Unlike a potato (edible tuber of the nightshade family), the sweet potato is a large edible root of the morning glory family. Sweet potatoes are typically recognized by their copper-colored skin and vibrant orange flesh. However there are varieties grown worldwide that display colors such as white, cream, yellow, and purple. The more common orange-fleshed sweet potatoes are a top source of beta-carotene, a precursor to vitamin A.
True to their name, sweet potatoes have a naturally sweet flavor, which is further enhanced through cooking methods like roasting. They are versatile and can also be steamed, pureed, baked, or grilled. They can be added to stews and soups, and roasted or grilled and placed on top of leafy greens for a delicious salad.
Benefits of Sweet Potatoes
1. Rich in Phytochemicals
Sweet potatoes with orange flesh are rich in beta-carotene, while sweet potatoes with purple flesh are richer in anthocyanins. Beta-carotene and anthocyanins are naturally occurring plant chemicals (phytochemicals) that give vegetables their bright colors. These phytochemicals are researched for their potential role in human health and disease prevention.
2. Heart Healthy
Sweet potatoes are rich in both potassium and magnesium which are healthy for our blood vessels and heart. They are also rich in vitamin B6 which helps reduce the chemical homocysteine in our bodies. Homocysteine has been linked to heart attacks.
3. Reduce Stress
Sweet potatoes are rich in magnesium, which is the relaxation and anti-stress mineral.
4. Provide Energy
Sweet potatoes are rich in iron, which helps give us energy.
5. Help in Weight Loss
Sweet potatoes are rich in fiber, which helps keep our digestive system healthy and keep us lean.
Ways to Enjoy Sweet Potatoes
Roasted: Cut sweet potatoes into wedges. Coat with olive and spread in a single layer on a baking sheet. Sprinkle with herbs or spices if desired. Bake at 375 F for 25 – 35 minutes or until the insides are tender and the outsides are crisp.
In soups or salads: Add cooked, diced sweet potatoes to soups or salads.
Mashed: For mashed sweet potatoes, use a fork, masher, or blender to puree the sweet potatoes. Add a liquid such as broth, milk, or water if a smoother consistency is desired. Season with pepper, herbs, or spices as desired.
Smoothies and baked goods: Puree sweet potatoes and add them to baked goods and smoothies.
Cauliflower is a member of the cruciferous vegetable family – along with cabbage, kale, broccoli, and brussel sprouts. Recent studies suggest that cruciferous vegetables are an excellent source of natural antioxidants due to their various phytochemicals.
Recent research also demonstrate that cruciferous vegetables like cauliflower are highly correlated with preventing chronic diseases including cardiovascular disease, diabetes, neurodegenerative disorders, and various forms of cancer.
Top Benefits of Cauliflower
1. Reduces cancer risk
Numerous studies demonstrate that cauliflower is useful for preventing breast cancer as well as colon, liver, lung, and stomach cancers. Cauliflower has been shown to have chemo-preventive agents that stall early phases of cancer development to help shut off tumor growth.
2. Fights inflammation
Cauliflower is rich in antioxidants and anti-inflammatory compounds which lower oxidative stress and the presence of free-radicals in our body. These compounds include vitamins, beta-carotene, quercetin, rutin, and kaempferol.
Cauliflower also contains vitamin C (one cup serving contains 73% of the recommended daily value of vitamin C) which helps to reduce inflammation, boost immunity, and keep the body free of harmful bacteria, infections, and common colds.
3. Decreases risk of cardiovascular disease and brain disorders
High levels of inflammation are correlated with an increased risk of cardiovascular disease, diabetes, and neurodegenerative disorders like Alzheimer’s and Parkinson’s disease. Cauliflower’s anti-inflammatory abilities (found mainly in its supply of vitamin K, vitamin C, various antioxidants, and omega-3 fatty acids) help keep arteries and blood vessels free from plaque build-up. This lessens the chances of developing high blood pressure and high cholesterol levels.
4. Provides high levels of vitamins and minerals
Cauliflower is a good source of vitamins C and K. Vitamin C is important for immunity. Vitamin K is a fat soluble vitamin responsible for healthy skeletal structure, blood clotting, and fighting inflammation in the body.
5. Improves digestion
Cruciferous vegetables are beneficial for digestion because of their rich supply of sulphur-containing compounds called glucosinolates. These compounds support proper nutrient absorption and toxin and waste removal.
6. Aids in weight loss
Cauliflower is extremely low in calories (only 29 calories per cup), and yet is high in volume and filling fiber. This makes it an excellent choice for those looking to lose weight, since you can consume large amounts of cauliflower and fill up without over-consuming calories.
Cauliflower also helps to reduce constipation and to keep excess waste or water moving out of your body, which helps you feel immediately better.
7. Preserves eye health
The sulphoraphane found in cauliflower has been shown to protect the vulnerable tissues of the retinal area from oxidative stress that can result in blindness, cataracts, macular degeneration, and more.
Ways to enjoy Cauliflower
Roast it: Cauliflower is delicious when roasted because roasting draws out its natural sweetness and caramelizes the florets.
Salads and pilafs: Add roasted cauliflower to salads and grains like quinoa or rice dishes.
Puree into soup: Cauliflower adds a great creamy texture to soups. Just chop, boil, puree, and stir into your favorite recipe.
Serve mashed: Steam florets until tender, then puree them with milk, a drizzle of olive oil, and salt and pepper to taste.
Avocado – that buttery green fruit that you can spread on a sandwich, dice into a salad, and mash into guacamole (America’s favorite dip). Research has demonstrated that avocados offer some surprising and powerful health benefits.
One of the most nutrient-dense foods, avocados are high in fiber, folate, potassium, vitamin E, and magnesium. No doubt, avocado nutrition makes it a powerful superfood.
Avocados have been cultivated for thousands of years. A favorite of the Aztecs, they were originally native to Central America. There are generally two types available in the USA today – the Hass avocado from California and the West Indian avocado from Florida.
Hass avocados are nutty, buttery and rich in monounsaturated oil (18 to 30 percent oil in each avocado). The light green Florida avocado is larger and juicier than the Hass variety, but it is less buttery, considerably lower in oil (3 to 5 percent oil) and has roughly 25 to 50 percent less fat than the Hass variety.
The avocado’s monounsaturated fat content is its biggest health claim. The only other fruit with a comparable amount of monounsaturated fat is the olive. The monounsaturated fat in avocados is oleic acid, which helps lower cholesterol. One study found that after seven days on a diet that included avocados, there were significant decreases in both total cholesterol and LDL (bad) cholesterol, as well as an 11 percent increase in HDL (good) cholesterol.
Reasons To Eat Avocados
1. Avocados are packed with carotenoids
Avocados are a great source of lutein, a carotenoid that works as an antioxidant and helps protect against eye disease. They also contain related carotenoids zeaxanthin, alpha-carotene and beta-carotene, as well as vitamin E.
2. Avocados are rich in healthy fats
Since carotenoids are fat-soluble, they need to be eaten with fats at the same meal to be absorbed into the blood stream. Avocados are rich in monounsaturated fats that help the body absorb these carotenoids from the avocado and also from other foods. An easy way to do this is to add sliced avocado to a mixed salad.
3. Avocados make you feel full
Half an avocado contains 3.4 grams of fiber, including soluble and insoluble, both of which your body needs to keep the digestive system running smoothly. The soluble fiber also slows the breakdown of carbohydrates in your body, helping you feel full longer.
Avocados also contain oleic acid, a monounsaturated fat that activates the part of your brain that makes you feel full. Healthier unsaturated fats containing oleic acid have been shown to produce a greater feeling of satiety than less healthy saturated fats and trans fats found in processed foods.
4. Avocados are rich in folate
One cup of avocado contains almost a quarter of the recommended daily intake of folate, a vitamin which cuts the risk of birth defects. So if you are pregnant, or planning to be, avocados will help protect your unborn baby.
A high folate intake is also associated with a lower risk of heart attacks and heart disease. So avocados could help keep your heart healthy.
5. Avocados can help lower your cholesterol
In addition to making you feel full, the oleic acid in avocados can help lower cholesterol levels. In one study, an avocado-rich diet resulted in a significant reduction in total cholesterol levels and an 11 percent increase in HDL (good) cholesterol.
6. Avocados can regulate your blood pressure
Avocados are full of potassium and magnesium, two nutrients known to lower blood pressure. A one-cup serving of avocado contains 15% of the RDI of potassium compare to 11% in bananas, which are a typical high-potassium food. The avocado also contains 14% of the RDI of magnesium, more than several fruits including the banana, strawberry, and kiwi.
7. Avocados taste great
Avocados are a healthy way to boost the flavor and texture of your meals. Toss chopped avocados on a salad or bowl of soup. Serve guacamole as an appetizer or condiment.
