What does the blood pressure reading 130/90 mean? Is this a healthy blood pressure or not?
Lorico [155]

Answer with Explanation:

High Blood Pressure refers to a condition wherein the heart is pumping more blood, thus causing a narrowing of the arteries. Such narrowing of arteries causes the pressure of blood to increase.

A person's blood pressure is dependent on the "systole" and "diastole" of the person. The "systole" is the pressure on top of the reading and is caused by the contraction of the ventricles (between the first and second heart sounds). The "diastole" refers to the relaxation of the muscles.

Depending on your health condition and age, a blood pressure reading of 130/90 may be normal or abnormal. For example, if you have a kidney disease, your blood pressure may be elevated than normal. So, this makes 130/90 a normal blood pressure for you. However, if your normal blood pressure is 120/80 then you suddenly get 130/90, then it means this is abnormal for you. There are probably factors, such as eating salt foods that contributed to this.

<u>Normal blood pressure is 120/80 and less than 140/90.</u> Thus, we can consider 130/90 as a healthy blood pressure. Those blood pressure lower than this may also be acceptable. Remember that when you are getting older, your blood pressure is increasing because the arteries in your body is changing regarding its structures.

When Charlene visits her doctor, she is told that one way to slow the aging process is by the consumption of antioxidants. As a
grandymaker [24]

Answer: C. Vitamin E

Explanation: By way of introduction, we all know that a sure way of slowing aging is by the consumption of foods that contain antioxidants.

It is important to note that here are plant foods which have rich sources of antioxidants. They are most abundant in fruits and vegetables, as well as other foods including nuts, wholegrains and some meats, poultry and fish. Aside from the Vitamin E giving at the option, there are other good sources.

Good sources of specific antioxidants include:

i. Allium sulphur compounds – leeks, onions and garlic.

ii. Anthocyanins – eggplant, grapes and berries.

iii. Beta-carotene – pumpkin, mangoes, apricots, carrots, spinach and parsley.

iv. Catechins – red wine and tea

copper – seafood, lean meat, milk and nuts.

v. Cryptoxanthins – red capsicum, pumpkin and mangoes.

vi. Flavonoids – tea, green tea, citrus fruits, red wine, onion and apples.

vii. Indoles – cruciferous vegetables such as broccoli, cabbage and cauliflower.

viii. Isoflavonoids – soybeans, tofu, lentils, peas and milk.

ix. Lignans – sesame seeds, bran, whole grains and vegetables.

x. Lutein – green, leafy vegetables like spinach, and corn.

xi. Lycopene – tomatoes, pink grapefruit and watermelon.

xii. Manganese – seafood, lean meat, milk and nuts.

xiii. Polyphenol – thyme and oregano

xiv. Selenium – seafood, offal, lean meat and whole grains

xv. Vitamin A – liver, sweet potatoes, carrots, milk, and egg yolks.

xvi. vitamins C – oranges, blackcurrants, kiwifruit, mangoes, broccoli, spinach, capsicum and strawberries.

xvii. Vitamins E – vegetable oils (such as wheatgerm oil), avocados, nuts, seeds and whole grains.

xviii. zinc – seafood, lean meat, milk and nuts

xix. Zoochemicals – red meat, offal and fish.

However, there is an increasing evidence that antioxidants are more effective when obtained from whole foods, rather than isolated from a food and presented in tablet form – and some supplements can actually increase cancer risk. For instance, vitamin A (beta-carotene) has been associated with a reduced risk of certain cancers, but an increase in others, such as lung cancer in smokers, if vitamin A is purified from foodstuffs. A study examining the effects of vitamin E found that it did not offer the same benefits when taken as a supplement. Also, antioxidant minerals or vitamins can act as pro-oxidants or damaging ‘oxidants’ if they are consumed at levels significantly above the recommended amounts for dietary intake.

In conclusion, a well-balanced diet, which includes consuming antioxidants from whole foods, is best. If there is need on taking a supplement, seek supplements that contain all nutrients at the recommended levels.
