2. Why do we need Sugar? Write 5 to 10 sentences on the importance
of sugar in our bodies.
3. What are the negative effects of sugar in our bodies?
4. What is the best and worst forms of sugar? (list multiple)
Best-
Worst-
5. How much sugar should you consume in a day?

Answers

1. Sugar is the generic name for sweet-tasting, soluble carbohydrate and sugar cane is crushed, the juice is heated and filtered, then sent to a series of crystallisation steps to create crystals of raw sugar, followed by centrifugation to remove any remaining juice or syrup. The last step produces a small stream of remaining syrup called cane mill molasses containing up to 55% (wt.) sucrose and substantial amounts of invert sugar (glucose/fructose mixture) impurities. Sucrose is the fraction that becomes crystallised sugar

2. Sugars are an important source of energy with glucose being the most important for the body. The brain requires around 130 grams of sugar (glucose) per day to keep functioning. Sugar helps you store energy for later. Sugar is import to have in a healthy diet. The body has a natural feedback mechanism by which high glucose levels lead to increased insulin production and the body requires healthy insulin levels to function properly

3. To much sugar can cause weight gain and may increase your risk for heart disease. Sugary foods quickly spike blood sugar and insulin levels, causing increased androgen secretion, oil production and inflammation, all of which play a role in acne development. Excessive sugar intake may increase your chances of developing type 2 diabetes and higher your risk of getting cancer

4. Best sugars: stevia l, honey, pure maple syrup and coconut sugar

Worst sugars: added sugars , high fructose corn syrup, processed sugar

5. The AHA suggests an added-sugar limit of no more than 100 calories per day (about 24 grams of sugar) for most women and no more than 150 calories per day (36 grams of sugar) for most men.

What are some potential risks and safety concerns that come with lifelong fitness? Given your activity level, what minor or major injury risks do you face on a regular basis? How do you protect yourself from these risks?

Answers

Answer:

These include cardiovascular disease, heart failure, stroke, certain cancers, osteoporosis, obesity, type 2 diabetes, and hypertension (8). A recent study found that higher levels of total daily sitting time were associated with an increased risk of cardiovascular disease and diabetes, independent of physical activity.

Some of the most common minor injuries include strains, sprains, and bruises. These will most often occur during some sort of physical activity. Some people confuse strains and sprains and call them the same thing but there is a slight difference.

How Can One Prevent a Sprain or Strain?

Participate in a conditioning program to build muscle strength.

Do stretching exercises daily.

Always wear properly fitting shoes.

Nourish the muscles by eating a well-balanced diet.

Warm up before any sports activity, including practice.

A high level of exercise can result in muscle and bone injuries, as well as heart-related disorders, high blood pressure, and other complications, so the exercise should be maintained with a healthy diet.

What are the complications of the exercise?

There are several potential complications that can arise from exercise when the proper care is not taken, such as musculoskeletal injuries that include strains, sprains, fractures, etc.; cardiovascular issues such as heart attack due to complications; dehydration due to excess sweating and loss of electrolytes; fatigue; cramps, etc.

Hence, a high level of exercise can result in muscle and bone injuries, as well as heart-related disorders, high blood pressure, and other complications, so the exercise should be maintained with a healthy diet.

12. Why
are most weight loss aids ineffective?

Answers

Answer:

A few products, including green tea, fiber and low-fat dairy supplements, can have a modest weight loss benefit of 3-4 pounds (2 kilos), but it is important to know that most of these supplements were tested as part of a reduced calorie diet.

For most people, unless you alter your diet and get daily exercise, no supplement is going to have a big impact.

Explanation:

The key to weight loss is to eat whole grains, fruits, vegetables and lean meats, reduce calorie intake of high-fat foods, and to keep moving. Depending on the individual, increasing protein may be beneficial (especially for those trying to not lose lean tissue), but the only way to lose weight is to make a lifestyle change.

Write a one page paper on the relationship between stress and exercise. In your paper, list three exercises activities that you could use to lower your stress level. Discuss a time when you experienced a certain level of stress in your life. Did you use exercise as a way to lower your stress level? What type of exercise? If not, do you think the way you handled your stress level would have benefited from exercise?

Answers

Answer:

You know that exercise does your body good, but you're too busy and stressed to fit it into your routine. Hold on a second — there's good news when it comes to exercise and stress.

Virtually any form of exercise, from aerobics to yoga, can act as a stress reliever. If you're not an athlete or even if you're out of shape, you can still make a little exercise go a long way toward stress management. Discover the connection between exercise and stress relief and why exercise should be part of your stress management plan.

Exercise increases your overall health and your sense of well-being, which puts more pep in your step every day. But exercise also has some direct stress-busting benefits.

It improves your mood. Regular exercise can increase self-confidence, improve your mood, help you relax, and lower symptoms of mild depression and anxiety. Exercise can also improve your sleep, which is often disrupted by stress, depression and anxiety. All of these exercise benefits can ease your stress levels and give you a sense of command over your body and your life.

It reduces negative effects of stress. Exercise can provide stress relief for your body while imitating effects of stress, such as the flight or fight response, and helping your body and its systems practice working together through those effects. This can also lead to positive effects in your body—including your cardiovascular, digestive and immune systems—by helping protect your body from harmful effects of stress.

Walk before you run. Build up your fitness level gradually. Excitement about a new program can lead to overdoing it and possibly even injury.

Whatever you do, don't think of exercise as just one more thing on your to-do list. Find an activity you enjoy — whether it's an active tennis match or a meditative meander down to a local park and back — and make it part of your regular routine. Any form of physical activity can help you unwind and become an important part of your approach to easing stress.
